+ The generic interrupt handling layer is designed to provide a
+ complete abstraction of interrupt handling for device drivers.
+ It is able to handle all the different types of interrupt controller
+ hardware. Device drivers use generic API functions to request, enable,
+ disable and free interrupts. The drivers do not have to know anything
+ about interrupt hardware details, so they can be used on different
+ platforms without code changes.

+ This documentation is provided to developers who want to implement
+ an interrupt subsystem based for their architecture, with the help
+ of the generic IRQ handling layer.

+ <chapter id="rationale">
+ <title>Rationale</title>
+ <para>
+ The original implementation of interrupt handling in Linux is using
+ the __do_IRQ() super-handler, which is able to deal with every
+ type of interrupt logic.
+ </para>
+ <para>
+ Originally, Russell King identified different types of handlers to
+ build a quite universal set for the ARM interrupt handler
+ implementation in Linux 2.5/2.6. He distinguished between:
+ <itemizedlist>
+ <listitem><para>Level type</para></listitem>
+ <listitem><para>Edge type</para></listitem>
+ <listitem><para>Simple type</para></listitem>
+ </itemizedlist>
+ In the SMP world of the __do_IRQ() super-handler another type
+ was identified:
+ <itemizedlist>
+ <listitem><para>Per CPU type</para></listitem>
+ </itemizedlist>
+ </para>
+ <para>
+ This split implementation of highlevel IRQ handlers allows us to
+ optimize the flow of the interrupt handling for each specific
+ interrupt type. This reduces complexity in that particular codepath
+ and allows the optimized handling of a given type.
+ </para>
+ <para>
+ The original general IRQ implementation used hw_interrupt_type
+ structures and their ->ack(), ->end() [etc.] callbacks to
+ differentiate the flow control in the super-handler. This leads to
+ a mix of flow logic and lowlevel hardware logic, and it also leads
+ to unnecessary code duplication: for example in i386, there is a
+ ioapic_level_irq and a ioapic_edge_irq irq-type which share many
+ of the lowlevel details but have different flow handling.
+ </para>
+ <para>
+ A more natural abstraction is the clean separation of the
+ 'irq flow' and the 'chip details'.
+ </para>
+ <para>
+ Analysing a couple of architecture's IRQ subsystem implementations
+ reveals that most of them can use a generic set of 'irq flow'
+ methods and only need to add the chip level specific code.
+ The separation is also valuable for (sub)architectures
+ which need specific quirks in the irq flow itself but not in the
+ chip-details - and thus provides a more transparent IRQ subsystem
+ design.
+ </para>
+ <para>
+ Each interrupt descriptor is assigned its own highlevel flow
+ handler, which is normally one of the generic
+ implementations. (This highlevel flow handler implementation also
+ makes it simple to provide demultiplexing handlers which can be
+ found in embedded platforms on various architectures.)
+ </para>
+ <para>
+ The separation makes the generic interrupt handling layer more
+ flexible and extensible. For example, an (sub)architecture can
+ use a generic irq-flow implementation for 'level type' interrupts
+ and add a (sub)architecture specific 'edge type' implementation.
+ </para>
+ <para>
+ To make the transition to the new model easier and prevent the
+ breakage of existing implementations, the __do_IRQ() super-handler
+ is still available. This leads to a kind of duality for the time
+ being. Over time the new model should be used in more and more
+ architectures, as it enables smaller and cleaner IRQ subsystems.

+ Each interrupt is described by an interrupt descriptor structure

+ The descriptor structure contains status information and pointers
+ to the interrupt flow method and the interrupt chip structure
+ which are assigned to this interrupt.
+ </para>
+ <para>
+ Whenever an interrupt triggers, the lowlevel arch code calls into

+ <title>Delayed interrupt disable</title>
+ <para>
+ This per interrupt selectable feature, which was introduced by Russell
+ King in the ARM interrupt implementation, does not mask an interrupt
+ at the hardware level when disable_irq() is called. The interrupt is
+ kept enabled and is masked in the flow handler when an interrupt event
+ happens. This prevents losing edge interrupts on hardware which does
+ not store an edge interrupt event while the interrupt is disabled at
+ the hardware level. When an interrupt arrives while the IRQ_DISABLED
+ flag is set, then the interrupt is masked at the hardware level and
+ the IRQ_PENDING bit is set. When the interrupt is re-enabled by
+ enable_irq() the pending bit is checked and if it is set, the
+ interrupt is resent either via hardware or by a software resend
+ mechanism. (It's necessary to enable CONFIG_HARDIRQS_SW_RESEND when
+ you want to use the delayed interrupt disable feature and your
+ hardware is not capable of retriggering an interrupt.)
+ The delayed interrupt disable can be runtime enabled, per interrupt,
+ by setting the IRQ_DELAYED_DISABLE flag in the irq_desc status field.
+ </para>

+What is an IRQ?
+
+An IRQ is an interrupt request from a device.
+Currently they can come in over a pin, or over a packet.
+Several devices may be connected to the same pin thus
+sharing an IRQ.
+
+An IRQ number is a kernel identifier used to talk about a hardware
+interrupt source. Typically this is an index into the global irq_desc
+array, but except for what linux/interrupt.h implements the details
+are architecture specific.
+
+An IRQ number is an enumeration of the possible interrupt sources on a
+machine. Typically what is enumerated is the number of input pins on
+all of the interrupt controller in the system. In the case of ISA
+what is enumerated are the 16 input pins on the two i8259 interrupt
+controllers.
+
+Architectures can assign additional meaning to the IRQ numbers, and
+are encouraged to in the case where there is any manual configuration
+of the hardware involved. The ISA IRQs are a classic example of
+assigning this kind of additional meaning.

-===============================================================================
-Changes for patch v1
-
-- creation of devfs
-
-- modified miscellaneous character devices to support devfs
-===============================================================================
-Changes for patch v2
-
-- bug fix with manual inode creation
-===============================================================================
-Changes for patch v3
-
-- bugfixes
-
-- documentation improvements
-
-- created a couple of scripts (one to save&restore a devfs and the
- other to set up compatibility symlinks)
-
-- devfs support for SCSI discs. New name format is: sd_hHcCiIlL
-===============================================================================
-Changes for patch v4
-
-- bugfix for the directory reading code
-
-- bugfix for compilation with kerneld
-
-- devfs support for generic hard discs
-
-- rationalisation of the various watchdog drivers
-===============================================================================
-Changes for patch v5
-
-- support for mounting directly from entries in the devfs (it doesn't
- need to be mounted to do this), including the root filesystem.
- Mounting of swap partitions also works. Hence, now if you set
- CONFIG_DEVFS_ONLY to 'Y' then you won't be able to access your discs
- via ordinary device nodes. Naturally, the default is 'N' so that you
- can still use your old device nodes. If you want to mount from devfs
- entries, make sure you use: append = "root=/dev/sd_..." in your
- lilo.conf. It seems LILO looks for the device number (major&minor)
- and writes that into the kernel image :-(
-
-- support for character memory devices (/dev/null, /dev/zero, /dev/full
- and so on). Thanks to C. Scott Ananian <cananian@alumni.princeton.edu>

-
-
-What is it?
-
-Devfs is an alternative to "real" character and block special devices
-on your root filesystem. Kernel device drivers can register devices by
-name rather than major and minor numbers. These devices will appear in
-devfs automatically, with whatever default ownership and
-protection the driver specified. A daemon (devfsd) can be used to
-override these defaults. Devfs has been in the kernel since 2.3.46.
-
-NOTE that devfs is entirely optional. If you prefer the old
-disc-based device nodes, then simply leave CONFIG_DEVFS_FS=n (the
-default). In this case, nothing will change. ALSO NOTE that if you do
-enable devfs, the defaults are such that full compatibility is
-maintained with the old devices names.
-
-There are two aspects to devfs: one is the underlying device
-namespace, which is a namespace just like any mounted filesystem. The
-other aspect is the filesystem code which provides a view of the
-device namespace. The reason I make a distinction is because devfs
-can be mounted many times, with each mount showing the same device
-namespace. Changes made are global to all mounted devfs filesystems.
-Also, because the devfs namespace exists without any devfs mounts, you
-can easily mount the root filesystem by referring to an entry in the
-devfs namespace.
-
-
-The cost of devfs is a small increase in kernel code size and memory
-usage. About 7 pages of code (some of that in __init sections) and 72
-bytes for each entry in the namespace. A modest system has only a
-couple of hundred device entries, so this costs a few more
-pages. Compare this with the suggestion to put /dev on a <a
-href="#why-faq-ramdisc">ramdisc.
-
-On a typical machine, the cost is under 0.2 percent. On a modest
-system with 64 MBytes of RAM, the cost is under 0.1 percent. The
-accusations of "bloatware" levelled at devfs are not justified.
-
------------------------------------------------------------------------------
-
-
-Why do it?
-
-There are several problems that devfs addresses. Some of these
-problems are more serious than others (depending on your point of
-view), and some can be solved without devfs. However, the totality of
-these problems really calls out for devfs.
-
-The choice is a patchwork of inefficient user space solutions, which
-are complex and likely to be fragile, or to use a simple and efficient
-devfs which is robust.
-
-There have been many counter-proposals to devfs, all seeking to
-provide some of the benefits without actually implementing devfs. So
-far there has been an absence of code and no proposed alternative has
-been able to provide all the features that devfs does. Further,
-alternative proposals require far more complexity in user-space (and
-still deliver less functionality than devfs). Some people have the
-mantra of reducing "kernel bloat", but don't consider the effects on
-user-space.
-
-A good solution limits the total complexity of kernel-space and
-user-space.
-
-
-Major&minor allocation
-
-The existing scheme requires the allocation of major and minor device
-numbers for each and every device. This means that a central
-co-ordinating authority is required to issue these device numbers
-(unless you're developing a "private" device driver), in order to
-preserve uniqueness. Devfs shifts the burden to a namespace. This may
-not seem like a huge benefit, but actually it is. Since driver authors
-will naturally choose a device name which reflects the functionality
-of the device, there is far less potential for namespace conflict.
-Solving this requires a kernel change.
-
-/dev management
-
-Because you currently access devices through device nodes, these must
-be created by the system administrator. For standard devices you can
-usually find a MAKEDEV programme which creates all these (hundreds!)
-of nodes. This means that changes in the kernel must be reflected by
-changes in the MAKEDEV programme, or else the system administrator
-creates device nodes by hand.
-
-The basic problem is that there are two separate databases of
-major and minor numbers. One is in the kernel and one is in /dev (or
-in a MAKEDEV programme, if you want to look at it that way). This is
-duplication of information, which is not good practice.
-Solving this requires a kernel change.
-
-/dev growth
-
-A typical /dev has over 1200 nodes! Most of these devices simply don't
-exist because the hardware is not available. A huge /dev increases the
-time to access devices (I'm just referring to the dentry lookup times
-and the time taken to read inodes off disc: the next subsection shows
-some more horrors).
-
-An example of how big /dev can grow is if we consider SCSI devices:
-
-host 6 bits (say up to 64 hosts on a really big machine)
-channel 4 bits (say up to 16 SCSI buses per host)
-id 4 bits
-lun 3 bits
-partition 6 bits
-TOTAL 23 bits
-
-
-This requires 8 Mega (1024*1024) inodes if we want to store all
-possible device nodes. Even if we scrap everything but id,partition
-and assume a single host adapter with a single SCSI bus and only one
-logical unit per SCSI target (id), that's still 10 bits or 1024
-inodes. Each VFS inode takes around 256 bytes (kernel 2.1.78), so
-that's 256 kBytes of inode storage on disc (assuming real inodes take
-a similar amount of space as VFS inodes). This is actually not so bad,
-because disc is cheap these days. Embedded systems would care about
-256 kBytes of /dev inodes, but you could argue that embedded systems
-would have hand-tuned /dev directories. I've had to do just that on my
-embedded systems, but I would rather just leave it to devfs.
-
-Another issue is the time taken to lookup an inode when first
-referenced. Not only does this take time in scanning through a list in
-memory, but also the seek times to read the inodes off disc.
-This could be solved in user-space using a clever programme which
-scanned the kernel logs and deleted /dev entries which are not
-available and created them when they were available. This programme
-would need to be run every time a new module was loaded, which would
-slow things down a lot.
-
-There is an existing programme called scsidev which will automatically
-create device nodes for SCSI devices. It can do this by scanning files
-in /proc/scsi. Unfortunately, to extend this idea to other device
-nodes would require significant modifications to existing drivers (so
-they too would provide information in /proc). This is a non-trivial
-change (I should know: devfs has had to do something similar). Once
-you go to this much effort, you may as well use devfs itself (which
-also provides this information). Furthermore, such a system would
-likely be implemented in an ad-hoc fashion, as different drivers will
-provide their information in different ways.
-
-Devfs is much cleaner, because it (naturally) has a uniform mechanism
-to provide this information: the device nodes themselves!
-
-
-Node to driver file_operations translation
-
-There is an important difference between the way disc-based character
-and block nodes and devfs entries make the connection between an entry
-in /dev and the actual device driver.
-
-With the current 8 bit major and minor numbers the connection between
-disc-based c&b nodes and per-major drivers is done through a
-fixed-length table of 128 entries. The various filesystem types set
-the inode operations for c&b nodes to {chr,blk}dev_inode_operations,
-so when a device is opened a few quick levels of indirection bring us
-to the driver file_operations.
-
-For miscellaneous character devices a second step is required: there
-is a scan for the driver entry with the same minor number as the file
-that was opened, and the appropriate minor open method is called. This
-scanning is done *every time* you open a device node. Potentially, you
-may be searching through dozens of misc. entries before you find your
-open method. While not an enormous performance overhead, this does
-seem pointless.
-
-Linux *must* move beyond the 8 bit major and minor barrier,
-somehow. If we simply increase each to 16 bits, then the indexing
-scheme used for major driver lookup becomes untenable, because the
-major tables (one each for character and block devices) would need to
-be 64 k entries long (512 kBytes on x86, 1 MByte for 64 bit
-systems). So we would have to use a scheme like that used for
-miscellaneous character devices, which means the search time goes up
-linearly with the average number of major device drivers on your
-system. Not all "devices" are hardware, some are higher-level drivers
-like KGI, so you can get more "devices" without adding hardware
-You can improve this by creating an ordered (balanced:-)
-binary tree, in which case your search time becomes log(N).
-Alternatively, you can use hashing to speed up the search.
-But why do that search at all if you don't have to? Once again, it
-seems pointless.
-
-Note that devfs doesn't use the major&minor system. For devfs
-entries, the connection is done when you lookup the /dev entry. When
-devfs_register() is called, an internal table is appended which has
-the entry name and the file_operations. If the dentry cache doesn't
-have the /dev entry already, this internal table is scanned to get the
-file_operations, and an inode is created. If the dentry cache already
-has the entry, there is *no lookup time* (other than the dentry scan
-itself, but we can't avoid that anyway, and besides Linux dentries
-cream other OS's which don't have them:-). Furthermore, the number of
-node entries in a devfs is only the number of available device
-entries, not the number of *conceivable* entries. Even if you remove
-unnecessary entries in a disc-based /dev, the number of conceivable
-entries remains the same: you just limit yourself in order to save
-space.
-
-Devfs provides a fast connection between a VFS node and the device
-driver, in a scalable way.
-
-/dev as a system administration tool
-
-Right now /dev contains a list of conceivable devices, most of which I
-don't have. Devfs only shows those devices available on my
-system. This means that listing /dev is a handy way of checking what
-devices are available.
-
-Major&minor size
-
-Existing major and minor numbers are limited to 8 bits each. This is
-now a limiting factor for some drivers, particularly the SCSI disc
-driver, which consumes a single major number. Only 16 discs are
-supported, and each disc may have only 15 partitions. Maybe this isn't
-a problem for you, but some of us are building huge Linux systems with
-disc arrays. With devfs an arbitrary pointer can be associated with
-each device entry, which can be used to give an effective 32 bit
-device identifier (i.e. that's like having a 32 bit minor
-number). Since this is private to the kernel, there are no C library
-compatibility issues which you would have with increasing major and
-minor number sizes. See the section on "Allocation of Device Numbers"
-for details on maintaining compatibility with userspace.
-
-Solving this requires a kernel change.
-
-Since writing this, the kernel has been modified so that the SCSI disc
-driver has more major numbers allocated to it and now supports up to
-128 discs. Since these major numbers are non-contiguous (a result of
-unplanned expansion), the implementation is a little more cumbersome
-than originally.
-
-Just like the changes to IPv4 to fix impending limitations in the
-address space, people find ways around the limitations. In the long
-run, however, solutions like IPv6 or devfs can't be put off forever.
-
-Read-only root filesystem
-
-Having your device nodes on the root filesystem means that you can't
-operate properly with a read-only root filesystem. This is because you
-want to change ownerships and protections of tty devices. Existing
-practice prevents you using a CD-ROM as your root filesystem for a
-*real* system. Sure, you can boot off a CD-ROM, but you can't change
-tty ownerships, so it's only good for installing.
-
-Also, you can't use a shared NFS root filesystem for a cluster of
-discless Linux machines (having tty ownerships changed on a common
-/dev is not good). Nor can you embed your root filesystem in a
-ROM-FS.
-
-You can get around this by creating a RAMDISC at boot time, making
-an ext2 filesystem in it, mounting it somewhere and copying the
-contents of /dev into it, then unmounting it and mounting it over
-/dev.
-
-A devfs is a cleaner way of solving this.
-
-Non-Unix root filesystem
-
-Non-Unix filesystems (such as NTFS) can't be used for a root
-filesystem because they variously don't support character and block
-special files or symbolic links. You can't have a separate disc-based
-or RAMDISC-based filesystem mounted on /dev because you need device
-nodes before you can mount these. Devfs can be mounted without any
-device nodes. Devlinks won't work because symlinks aren't supported.
-An alternative solution is to use initrd to mount a RAMDISC initial
-root filesystem (which is populated with a minimal set of device
-nodes), and then construct a new /dev in another RAMDISC, and finally
-switch to your non-Unix root filesystem. This requires clever boot
-scripts and a fragile and conceptually complex boot procedure.
-
-Devfs solves this in a robust and conceptually simple way.
-
-PTY security
-
-Current pseudo-tty (pty) devices are owned by root and read-writable
-by everyone. The user of a pty-pair cannot change
-ownership/protections without being suid-root.
-
-This could be solved with a secure user-space daemon which runs as
-root and does the actual creation of pty-pairs. Such a daemon would
-require modification to *every* programme that wants to use this new
-mechanism. It also slows down creation of pty-pairs.
-
-An alternative is to create a new open_pty() syscall which does much
-the same thing as the user-space daemon. Once again, this requires
-modifications to pty-handling programmes.
-
-The devfs solution allows a device driver to "tag" certain device
-files so that when an unopened device is opened, the ownerships are
-changed to the current euid and egid of the opening process, and the
-protections are changed to the default registered by the driver. When
-the device is closed ownership is set back to root and protections are
-set back to read-write for everybody. No programme need be changed.
-The devpts filesystem provides this auto-ownership feature for Unix98
-ptys. It doesn't support old-style pty devices, nor does it have all
-the other features of devfs.
-
-Intelligent device management
-
-Devfs implements a simple yet powerful protocol for communication with
-a device management daemon (devfsd) which runs in user space. It is
-possible to send a message (either synchronously or asynchronously) to
-devfsd on any event, such as registration/unregistration of device
-entries, opening and closing devices, looking up inodes, scanning
-directories and more. This has many possibilities. Some of these are
-already implemented. See:
-
-
-http://www.atnf.csiro.au/~rgooch/linux/
-
-Device entry registration events can be used by devfsd to change
-permissions of newly-created device nodes. This is one mechanism to
-control device permissions.
-
-Device entry registration/unregistration events can be used to run
-programmes or scripts. This can be used to provide automatic mounting
-of filesystems when a new block device media is inserted into the
-drive.
-
-Asynchronous device open and close events can be used to implement
-clever permissions management. For example, the default permissions on
-/dev/dsp do not allow everybody to read from the device. This is
-sensible, as you don't want some remote user recording what you say at
-your console. However, the console user is also prevented from
-recording. This behaviour is not desirable. With asynchronous device
-open and close events, you can have devfsd run a programme or script
-when console devices are opened to change the ownerships for *other*
-device nodes (such as /dev/dsp). On closure, you can run a different
-script to restore permissions. An advantage of this scheme over
-modifying the C library tty handling is that this works even if your
-programme crashes (how many times have you seen the utmp database with
-lingering entries for non-existent logins?).
-
-Synchronous device open events can be used to perform intelligent
-device access protections. Before the device driver open() method is
-called, the daemon must first validate the open attempt, by running an
-external programme or script. This is far more flexible than access
-control lists, as access can be determined on the basis of other
-system conditions instead of just the UID and GID.
-
-Inode lookup events can be used to authenticate module autoload
-requests. Instead of using kmod directly, the event is sent to
-devfsd which can implement an arbitrary authentication before loading
-the module itself.
-
-Inode lookup events can also be used to construct arbitrary
-namespaces, without having to resort to populating devfs with symlinks
-to devices that don't exist.
-
-Speculative Device Scanning
-
-Consider an application (like cdparanoia) that wants to find all
-CD-ROM devices on the system (SCSI, IDE and other types), whether or
-not their respective modules are loaded. The application must
-speculatively open certain device nodes (such as /dev/sr0 for the SCSI
-CD-ROMs) in order to make sure the module is loaded. This requires
-that all Linux distributions follow the standard device naming scheme
-(last time I looked RedHat did things differently). Devfs solves the
-naming problem.
-
-The same application also wants to see which devices are actually
-available on the system. With the existing system it needs to read the
-/dev directory and speculatively open each /dev/sr* device to
-determine if the device exists or not. With a large /dev this is an
-inefficient operation, especially if there are many /dev/sr* nodes. A
-solution like scsidev could reduce the number of /dev/sr* entries (but
-of course that also requires all that inefficient directory scanning).
-
-With devfs, the application can open the /dev/sr directory
-(which triggers the module autoloading if required), and proceed to
-read /dev/sr. Since only the available devices will have
-entries, there are no inefficencies in directory scanning or device
-openings.
-
------------------------------------------------------------------------------
-
-Who else does it?
-
-FreeBSD has a devfs implementation. Solaris and AIX each have a
-pseudo-devfs (something akin to scsidev but for all devices, with some
-unspecified kernel support). BeOS, Plan9 and QNX also have it. SGI's
-IRIX 6.4 and above also have a device filesystem.
-
-While we shouldn't just automatically do something because others do
-it, we should not ignore the work of others either. FreeBSD has a lot
-of competent people working on it, so their opinion should not be
-blithely ignored.
-
------------------------------------------------------------------------------
-
-
-How it works
-
-Registering device entries
-
-For every entry (device node) in a devfs-based /dev a driver must call
-devfs_register(). This adds the name of the device entry, the
-file_operations structure pointer and a few other things to an
-internal table. Device entries may be added and removed at any
-time. When a device entry is registered, it automagically appears in
-any mounted devfs'.
-
-Inode lookup
-
-When a lookup operation on an entry is performed and if there is no
-driver information for that entry devfs will attempt to call
-devfsd. If still no driver information can be found then a negative
-dentry is yielded and the next stage operation will be called by the
-VFS (such as create() or mknod() inode methods). If driver information
-can be found, an inode is created (if one does not exist already) and
-all is well.
-
-Manually creating device nodes
-
-The mknod() method allows you to create an ordinary named pipe in the
-devfs, or you can create a character or block special inode if one
-does not already exist. You may wish to create a character or block
-special inode so that you can set permissions and ownership. Later, if
-a device driver registers an entry with the same name, the
-permissions, ownership and times are retained. This is how you can set
-the protections on a device even before the driver is loaded. Once you
-create an inode it appears in the directory listing.
-
-Unregistering device entries
-
-A device driver calls devfs_unregister() to unregister an entry.
-
-Chroot() gaols
-
-2.2.x kernels
-
-The semantics of inode creation are different when devfs is mounted
-with the "explicit" option. Now, when a device entry is registered, it
-will not appear until you use mknod() to create the device. It doesn't
-matter if you mknod() before or after the device is registered with
-devfs_register(). The purpose of this behaviour is to support
-chroot(2) gaols, where you want to mount a minimal devfs inside the
-gaol. Only the devices you specifically want to be available (through
-your mknod() setup) will be accessible.
-
-2.4.x kernels
-
-As of kernel 2.3.99, the VFS has had the ability to rebind parts of
-the global filesystem namespace into another part of the namespace.
-This now works even at the leaf-node level, which means that
-individual files and device nodes may be bound into other parts of the
-namespace. This is like making links, but better, because it works
-across filesystems (unlike hard links) and works through chroot()
-gaols (unlike symbolic links).
-
-Because of these improvements to the VFS, the multi-mount capability
-in devfs is no longer needed. The administrator may create a minimal
-device tree inside a chroot(2) gaol by using VFS bindings. As this
-provides most of the features of the devfs multi-mount capability, I
-removed the multi-mount support code (after issuing an RFC). This
-yielded code size reductions and simplifications.
-
-If you want to construct a minimal chroot() gaol, the following
-command should suffice:
-
-mount --bind /dev/null /gaol/dev/null
-
-
-Repeat for other device nodes you want to expose. Simple!

-
-Operational issues
-
-
-Instructions for the impatient
-
-Nobody likes reading documentation. People just want to get in there
-and play. So this section tells you quickly the steps you need to take
-to run with devfs mounted over /dev. Skip these steps and you will end
-up with a nearly unbootable system. Subsequent sections describe the
-issues in more detail, and discuss non-essential configuration
-options.
-
-Devfsd
-OK, if you're reading this, I assume you want to play with
-devfs. First you should ensure that /usr/src/linux contains a
-recent kernel source tree. Then you need to compile devfsd, the device
-management daemon, available at
-
-http://www.atnf.csiro.au/~rgooch/linux/.
-Because the kernel has a naming scheme
-which is quite different from the old naming scheme, you need to
-install devfsd so that software and configuration files that use the
-old naming scheme will not break.
-
-Compile and install devfsd. You will be provided with a default
-configuration file /etc/devfsd.conf which will provide
-compatibility symlinks for the old naming scheme. Don't change this
-config file unless you know what you're doing. Even if you think you
-do know what you're doing, don't change it until you've followed all
-the steps below and booted a devfs-enabled system and verified that it
-works.
-
-Now edit your main system boot script so that devfsd is started at the
-very beginning (before any filesystem
-checks). /etc/rc.d/rc.sysinit is often the main boot script
-on systems with SysV-style boot scripts. On systems with BSD-style
-boot scripts it is often /etc/rc. Also check
-/sbin/rc.
-
-NOTE that the line you put into the boot
-script should be exactly:
-
-/sbin/devfsd /dev
-
-DO NOT use some special daemon-launching
-programme, otherwise the boot script may not wait for devfsd to finish
-initialising.
-
-System Libraries
-There may still be some problems because of broken software making
-assumptions about device names. In particular, some software does not
-handle devices which are symbolic links. If you are running a libc 5
-based system, install libc 5.4.44 (if you have libc 5.4.46, go back to
-libc 5.4.44, which is actually correct). If you are running a glibc
-based system, make sure you have glibc 2.1.3 or later.
-
-/etc/securetty
-PAM (Pluggable Authentication Modules) is supposed to be a flexible
-mechanism for providing better user authentication and access to
-services. Unfortunately, it's also fragile, complex and undocumented
-(check out RedHat 6.1, and probably other distributions as well). PAM
-has problems with symbolic links. Append the following lines to your
-/etc/securetty file:
-
-vc/1
-vc/2
-vc/3
-vc/4
-vc/5
-vc/6
-vc/7
-vc/8
-
-This will not weaken security. If you have a version of util-linux
-earlier than 2.10.h, please upgrade to 2.10.h or later. If you
-absolutely cannot upgrade, then also append the following lines to
-your /etc/securetty file:
-
-1
-2
-3
-4
-5
-6
-7
-8
-
-This may potentially weaken security by allowing root logins over the
-network (a password is still required, though). However, since there
-are problems with dealing with symlinks, I'm suspicious of the level
-of security offered in any case.
-
-XFree86
-While not essential, it's probably a good idea to upgrade to XFree86
-4.0, as patches went in to make it more devfs-friendly. If you don't,
-you'll probably need to apply the following patch to
-/etc/security/console.perms so that ordinary users can run
-startx. Note that not all distributions have this file (e.g. Debian),
-so if it's not present, don't worry about it.

-
-Disable devpts
-I've had a report of devpts mounted on /dev/pts not working
-correctly. Since devfs will also manage /dev/pts, there is no
-need to mount devpts as well. You should either edit your
-/etc/fstab so devpts is not mounted, or disable devpts from
-your kernel configuration.
-
-Unsupported drivers
-Not all drivers have devfs support. If you depend on one of these
-drivers, you will need to create a script or tarfile that you can use
-at boot time to create device nodes as appropriate. There is a
-section which describes this. Another
-section lists the drivers which have
-devfs support.
-
-/dev/mouse
-
-Many disributions configure /dev/mouse to be the mouse device
-for XFree86 and GPM. I actually think this is a bad idea, because it
-adds another level of indirection. When looking at a config file, if
-you see /dev/mouse you're left wondering which mouse
-is being referred to. Hence I recommend putting the actual mouse
-device (for example /dev/psaux) into your
-/etc/X11/XF86Config file (and similarly for the GPM
-configuration file).
-
-Alternatively, use the same technique used for unsupported drivers
-described above.
-
-The Kernel
-Finally, you need to make sure devfs is compiled into your kernel. Set
-CONFIG_EXPERIMENTAL=y, CONFIG_DEVFS_FS=y and CONFIG_DEVFS_MOUNT=y by
-using favourite configuration tool (i.e. make config or
-make xconfig) and then make clean and then recompile your kernel and
-modules. At boot, devfs will be mounted onto /dev.
-
-If you encounter problems booting (for example if you forgot a
-configuration step), you can pass devfs=nomount at the kernel
-boot command line. This will prevent the kernel from mounting devfs at
-boot time onto /dev.
-
-In general, a kernel built with CONFIG_DEVFS_FS=y but without mounting
-devfs onto /dev is completely safe, and requires no
-configuration changes. One exception to take note of is when
-LABEL= directives are used in /etc/fstab. In this
-case you will be unable to boot properly. This is because the
-mount(8) programme uses /proc/partitions as part of
-the volume label search process, and the device names it finds are not
-available, because setting CONFIG_DEVFS_FS=y changes the names in
-/proc/partitions, irrespective of whether devfs is mounted.
-
-Now you've finished all the steps required. You're now ready to boot
-your shiny new kernel. Enjoy.
-
-Changing the configuration
-
-OK, you've now booted a devfs-enabled system, and everything works.
-Now you may feel like changing the configuration (common targets are
-/etc/fstab and /etc/devfsd.conf). Since you have a
-system that works, if you make any changes and it doesn't work, you
-now know that you only have to restore your configuration files to the
-default and it will work again.
-
-
-Permissions persistence across reboots
-
-If you don't use mknod(2) to create a device file, nor use chmod(2) or
-chown(2) to change the ownerships/permissions, the inode ctime will
-remain at 0 (the epoch, 12 am, 1-JAN-1970, GMT). Anything with a ctime
-later than this has had it's ownership/permissions changed. Hence, a
-simple script or programme may be used to tar up all changed inodes,
-prior to shutdown. Although effective, many consider this approach a
-kludge.
-
-A much better approach is to use devfsd to save and restore
-permissions. It may be configured to record changes in permissions and
-will save them in a database (in fact a directory tree), and restore
-these upon boot. This is an efficient method and results in immediate
-saving of current permissions (unlike the tar approach, which saves
-permissions at some unspecified future time).
-
-The default configuration file supplied with devfsd has config entries
-which you may uncomment to enable persistence management.
-
-If you decide to use the tar approach anyway, be aware that tar will
-first unlink(2) an inode before creating a new device node. The
-unlink(2) has the effect of breaking the connection between a devfs
-entry and the device driver. If you use the "devfs=only" boot option,
-you lose access to the device driver, requiring you to reload the
-module. I consider this a bug in tar (there is no real need to
-unlink(2) the inode first).
-
-Alternatively, you can use devfsd to provide more sophisticated
-management of device permissions. You can use devfsd to store
-permissions for whole groups of devices with a single configuration
-entry, rather than the conventional single entry per device entry.
-
-Permissions database stored in mounted-over /dev
-
-If you wish to save and restore your device permissions into the
-disc-based /dev while still mounting devfs onto /dev
-you may do so. This requires a 2.4.x kernel (in fact, 2.3.99 or
-later), which has the VFS binding facility. You need to do the
-following to set this up:
-
-
-
-make sure the kernel does not mount devfs at boot time
-
-
-make sure you have a correct /dev/console entry in your
-root file-system (where your disc-based /dev lives)
-
-create the /dev-state directory
-
-
-add the following lines near the very beginning of your boot
-scripts:
-
-mount --bind /dev /dev-state
-mount -t devfs none /dev
-devfsd /dev
-
-
-
-
-add the following lines to your /etc/devfsd.conf file:
-
-REGISTER ^pt[sy] IGNORE
-CREATE ^pt[sy] IGNORE
-CHANGE ^pt[sy] IGNORE
-DELETE ^pt[sy] IGNORE
-REGISTER .* COPY /dev-state/$devname $devpath
-CREATE .* COPY $devpath /dev-state/$devname
-CHANGE .* COPY $devpath /dev-state/$devname
-DELETE .* CFUNCTION GLOBAL unlink /dev-state/$devname
-RESTORE /dev-state
-
-Note that the sample devfsd.conf file contains these lines,
-as well as other sample configurations you may find useful. See the
-devfsd distribution
-
-
-reboot.
-
-
-
-
-Permissions database stored in normal directory
-
-If you are using an older kernel which doesn't support VFS binding,
-then you won't be able to have the permissions database in a
-mounted-over /dev. However, you can still use a regular
-directory to store the database. The sample /etc/devfsd.conf
-file above may still be used. You will need to create the
-/dev-state directory prior to installing devfsd. If you have
-old permissions in /dev, then just copy (or move) the device
-nodes over to the new directory.
-
-Which method is better?
-
-The best method is to have the permissions database stored in the
-mounted-over /dev. This is because you will not need to copy
-device nodes over to /dev-state, and because it allows you to
-switch between devfs and non-devfs kernels, without requiring you to
-copy permissions between /dev-state (for devfs) and
-/dev (for non-devfs).
-
-
-Dealing with drivers without devfs support
-
-Currently, not all device drivers in the kernel have been modified to
-use devfs. Device drivers which do not yet have devfs support will not
-automagically appear in devfs. The simplest way to create device nodes
-for these drivers is to unpack a tarfile containing the required
-device nodes. You can do this in your boot scripts. All your drivers
-will now work as before.
-
-Hopefully for most people devfs will have enough support so that they
-can mount devfs directly over /dev without losing most functionality
-(i.e. losing access to various devices). As of 22-JAN-1998 (devfs
-patch version 10) I am now running this way. All the devices I have
-are available in devfs, so I don't lose anything.
-
-WARNING: if your configuration requires the old-style device names
-(i.e. /dev/hda1 or /dev/sda1), you must install devfsd and configure
-it to maintain compatibility entries. It is almost certain that you
-will require this. Note that the kernel creates a compatibility entry
-for the root device, so you don't need initrd.
-
-Note that you no longer need to mount devpts if you use Unix98 PTYs,
-as devfs can manage /dev/pts itself. This saves you some RAM, as you
-don't need to compile and install devpts. Note that some versions of
-glibc have a bug with Unix98 pty handling on devfs systems. Contact
-the glibc maintainers for a fix. Glibc 2.1.3 has the fix.
-
-Note also that apart from editing /etc/fstab, other things will need
-to be changed if you *don't* install devfsd. Some software (like the X
-server) hard-wire device names in their source. It really is much
-easier to install devfsd so that compatibility entries are created.
-You can then slowly migrate your system to using the new device names
-(for example, by starting with /etc/fstab), and then limiting the
-compatibility entries that devfsd creates.
-
-IF YOU CONFIGURE TO MOUNT DEVFS AT BOOT, MAKE SURE YOU INSTALL DEVFSD
-BEFORE YOU BOOT A DEVFS-ENABLED KERNEL!
-
-Now that devfs has gone into the 2.3.46 kernel, I'm getting a lot of
-reports back. Many of these are because people are trying to run
-without devfsd, and hence some things break. Please just run devfsd if
-things break. I want to concentrate on real bugs rather than
-misconfiguration problems at the moment. If people are willing to fix
-bugs/false assumptions in other code (i.e. glibc, X server) and submit
-that to the respective maintainers, that would be great.
-
-
-All the way with Devfs
-
-The devfs kernel patch creates a rationalised device tree. As stated
-above, if you want to keep using the old /dev naming scheme,
-you just need to configure devfsd appopriately (see the man
-page). People who prefer the old names can ignore this section. For
-those of us who like the rationalised names and an uncluttered
-/dev, read on.
-
-If you don't run devfsd, or don't enable compatibility entry
-management, then you will have to configure your system to use the new
-names. For example, you will then need to edit your
-/etc/fstab to use the new disc naming scheme. If you want to
-be able to boot non-devfs kernels, you will need compatibility
-symlinks in the underlying disc-based /dev pointing back to
-the old-style names for when you boot a kernel without devfs.
-
-You can selectively decide which devices you want compatibility
-entries for. For example, you may only want compatibility entries for
-BSD pseudo-terminal devices (otherwise you'll have to patch you C
-library or use Unix98 ptys instead). It's just a matter of putting in
-the correct regular expression into /dev/devfsd.conf.
-
-There are other choices of naming schemes that you may prefer. For
-example, I don't use the kernel-supplied
-names, because they are too verbose. A common misconception is
-that the kernel-supplied names are meant to be used directly in
-configuration files. This is not the case. They are designed to
-reflect the layout of the devices attached and to provide easy
-classification.
-
-If you like the kernel-supplied names, that's fine. If you don't then
-you should be using devfsd to construct a namespace more to your
-liking. Devfsd has built-in code to construct a
-namespace that is both logical and easy to
-manage. In essence, it creates a convenient abbreviation of the
-kernel-supplied namespace.
-
-You are of course free to build your own namespace. Devfsd has all the
-infrastructure required to make this easy for you. All you need do is
-write a script. You can even write some C code and devfsd can load the
-shared object as a callable extension.
-
-
-Other Issues
-
-The init programme
-Another thing to take note of is whether your init programme
-creates a Unix socket /dev/telinit. Some versions of init
-create /dev/telinit so that the telinit programme can
-communicate with the init process. If you have such a system you need
-to make sure that devfs is mounted over /dev *before* init
-starts. In other words, you can't leave the mounting of devfs to
-/etc/rc, since this is executed after init. Other
-versions of init require a named pipe /dev/initctl
-which must exist *before* init starts. Once again, you need to
-mount devfs and then create the named pipe *before* init
-starts.
-
-The default behaviour now is not to mount devfs onto /dev at
-boot time for 2.3.x and later kernels. You can correct this with the
-"devfs=mount" boot option. This solves any problems with init,
-and also prevents the dreaded:
-
-Cannot open initial console
-
-message. For 2.2.x kernels where you need to apply the devfs patch,
-the default is to mount.
-
-If you have automatic mounting of devfs onto /dev then you
-may need to create /dev/initctl in your boot scripts. The
-following lines should suffice:
-
-mknod /dev/initctl p
-kill -SIGUSR1 1 # tell init that /dev/initctl now exists
-
-Alternatively, if you don't want the kernel to mount devfs onto
-/dev then you could use the following procedure is a
-guideline for how to get around /dev/initctl problems:
-
-# cd /sbin
-# mv init init.real
-# cat > init
-#! /bin/sh
-mount -n -t devfs none /dev
-mknod /dev/initctl p
-exec /sbin/init.real $*
-[control-D]
-# chmod a+x init
-
-Note that newer versions of init create /dev/initctl
-automatically, so you don't have to worry about this.
-
-Module autoloading
-You will need to configure devfsd to enable module
-autoloading. The following lines should be placed in your
-/etc/devfsd.conf file:
-
-LOOKUP .* MODLOAD
-
-
-As of devfsd-v1.3.10, a generic /etc/modules.devfs
-configuration file is installed, which is used by the MODLOAD
-action. This should be sufficient for most configurations. If you
-require further configuration, edit your /etc/modules.conf
-file. The way module autoloading work with devfs is:
-
-
-a process attempts to lookup a device node (e.g. /dev/fred)
-
-
-if that device node does not exist, the full pathname is passed to
-devfsd as a string
-
-
-devfsd will pass the string to the modprobe programme (provided the
-configuration line shown above is present), and specifies that
-/etc/modules.devfs is the configuration file
-
-
-/etc/modules.devfs includes /etc/modules.conf to
-access local configurations
-
-modprobe will search it's configuration files, looking for an alias
-that translates the pathname into a module name
-
-
-the translated pathname is then used to load the module.
-
-
-If you wanted a lookup of /dev/fred to load the
-mymod module, you would require the following configuration
-line in /etc/modules.conf:
-
-alias /dev/fred mymod
-
-The /etc/modules.devfs configuration file provides many such
-aliases for standard device names. If you look closely at this file,
-you will note that some modules require multiple alias configuration
-lines. This is required to support module autoloading for old and new
-device names.
-
-Mounting root off a devfs device
-If you wish to mount root off a devfs device when you pass the
-"devfs=only" boot option, then you need to pass in the
-"root=<device>" option to the kernel when booting. If you use
-LILO, then you must have this in lilo.conf:
-
-append = "root=<device>"
-
-Surprised? Yep, so was I. It turns out if you have (as most people
-do):
-
-root = <device>
-
-
-then LILO will determine the device number of <device> and will
-write that device number into a special place in the kernel image
-before starting the kernel, and the kernel will use that device number
-to mount the root filesystem. So, using the "append" variety ensures
-that LILO passes the root filesystem device as a string, which devfs
-can then use.
-
-Note that this isn't an issue if you don't pass "devfs=only".
-
-TTY issues
-The ttyname(3) function in some versions of the C library makes
-false assumptions about device entries which are symbolic links. The
-tty(1) programme is one that depends on this function. I've
-written a patch to libc 5.4.43 which fixes this. This has been
-included in libc 5.4.44 and a similar fix is in glibc 2.1.3.
-
-
-Kernel Naming Scheme
-
-The kernel provides a default naming scheme. This scheme is designed
-to make it easy to search for specific devices or device types, and to
-view the available devices. Some device types (such as hard discs),
-have a directory of entries, making it easy to see what devices of
-that class are available. Often, the entries are symbolic links into a
-directory tree that reflects the topology of available devices. The
-topological tree is useful for finding how your devices are arranged.
-
-Below is a list of the naming schemes for the most common drivers. A
-list of reserved device names is
-available for reference. Please send email to
-rgooch@atnf.csiro.au to obtain an allocation. Please be
-patient (the maintainer is busy). An alternative name may be allocated
-instead of the requested name, at the discretion of the maintainer.
-
-Disc Devices
-
-All discs, whether SCSI, IDE or whatever, are placed under the
-/dev/discs hierarchy:
-
- /dev/discs/disc0 first disc
- /dev/discs/disc1 second disc
-
-
-Each of these entries is a symbolic link to the directory for that
-device. The device directory contains:
-
- disc for the whole disc
- part* for individual partitions
-
-
-CD-ROM Devices
-
-All CD-ROMs, whether SCSI, IDE or whatever, are placed under the
-/dev/cdroms hierarchy:
-
- /dev/cdroms/cdrom0 first CD-ROM
- /dev/cdroms/cdrom1 second CD-ROM
-
-
-Each of these entries is a symbolic link to the real device entry for
-that device.
-
-Tape Devices
-
-All tapes, whether SCSI, IDE or whatever, are placed under the
-/dev/tapes hierarchy:
-
- /dev/tapes/tape0 first tape
- /dev/tapes/tape1 second tape
-
-
-Each of these entries is a symbolic link to the directory for that
-device. The device directory contains:
-
- mt for mode 0
- mtl for mode 1
- mtm for mode 2
- mta for mode 3
- mtn for mode 0, no rewind
- mtln for mode 1, no rewind
- mtmn for mode 2, no rewind
- mtan for mode 3, no rewind
-
-
-SCSI Devices
-
-To uniquely identify any SCSI device requires the following
-information:
-
- controller (host adapter)
- bus (SCSI channel)
- target (SCSI ID)
- unit (Logical Unit Number)
-
-
-All SCSI devices are placed under /dev/scsi (assuming devfs
-is mounted on /dev). Hence, a SCSI device with the following
-parameters: c=1,b=2,t=3,u=4 would appear as:
-
- /dev/scsi/host1/bus2/target3/lun4 device directory
-
-
-Inside this directory, a number of device entries may be created,
-depending on which SCSI device-type drivers were installed.
-
-See the section on the disc naming scheme to see what entries the SCSI
-disc driver creates.
-
-See the section on the tape naming scheme to see what entries the SCSI
-tape driver creates.
-
-The SCSI CD-ROM driver creates:
-
- cd
-
-
-The SCSI generic driver creates:
-
- generic
-
-
-IDE Devices
-
-To uniquely identify any IDE device requires the following
-information:
-
- controller
- bus (aka. primary/secondary)
- target (aka. master/slave)
- unit
-
-
-All IDE devices are placed under /dev/ide, and uses a similar
-naming scheme to the SCSI subsystem.
-
-XT Hard Discs
-
-All XT discs are placed under /dev/xd. The first XT disc has
-the directory /dev/xd/disc0.
-
-TTY devices
-
-The tty devices now appear as:
-
- New name Old-name Device Type
- -------- -------- -----------
- /dev/tts/{0,1,...} /dev/ttyS{0,1,...} Serial ports
- /dev/cua/{0,1,...} /dev/cua{0,1,...} Call out devices
- /dev/vc/0 /dev/tty Current virtual console
- /dev/vc/{1,2,...} /dev/tty{1...63} Virtual consoles
- /dev/vcc/{0,1,...} /dev/vcs{1...63} Virtual consoles
- /dev/pty/m{0,1,...} /dev/ptyp?? PTY masters
- /dev/pty/s{0,1,...} /dev/ttyp?? PTY slaves
-
-
-RAMDISCS
-
-The RAMDISCS are placed in their own directory, and are named thus:
-
- /dev/rd/{0,1,2,...}
-
-
-Meta Devices
-
-The meta devices are placed in their own directory, and are named
-thus:
-
- /dev/md/{0,1,2,...}
-
-
-Floppy discs
-
-Floppy discs are placed in the /dev/floppy directory.
-
-Loop devices
-
-Loop devices are placed in the /dev/loop directory.
-
-Sound devices
-
-Sound devices are placed in the /dev/sound directory
-(audio, sequencer, ...).
-
-
-Devfsd Naming Scheme
-
-Devfsd provides a naming scheme which is a convenient abbreviation of
-the kernel-supplied namespace. In some
-cases, the kernel-supplied naming scheme is quite convenient, so
-devfsd does not provide another naming scheme. The convenience names
-that devfsd creates are in fact the same names as the original devfs
-kernel patch created (before Linus mandated the Big Name
-Change). These are referred to as "new compatibility entries".
-
-In order to configure devfsd to create these convenience names, the
-following lines should be placed in your /etc/devfsd.conf:
-
-REGISTER .* MKNEWCOMPAT
-UNREGISTER .* RMNEWCOMPAT
-
-This will cause devfsd to create (and destroy) symbolic links which
-point to the kernel-supplied names.
-
-SCSI Hard Discs
-
-All SCSI discs are placed under /dev/sd (assuming devfs is
-mounted on /dev). Hence, a SCSI disc with the following
-parameters: c=1,b=2,t=3,u=4 would appear as:
-
- /dev/sd/c1b2t3u4 for the whole disc
- /dev/sd/c1b2t3u4p5 for the 5th partition
- /dev/sd/c1b2t3u4p5s6 for the 6th slice in the 5th partition
-
-
-SCSI Tapes
-
-All SCSI tapes are placed under /dev/st. A similar naming
-scheme is used as for SCSI discs. A SCSI tape with the
-parameters:c=1,b=2,t=3,u=4 would appear as:
-
- /dev/st/c1b2t3u4m0 for mode 0
- /dev/st/c1b2t3u4m1 for mode 1
- /dev/st/c1b2t3u4m2 for mode 2
- /dev/st/c1b2t3u4m3 for mode 3
- /dev/st/c1b2t3u4m0n for mode 0, no rewind
- /dev/st/c1b2t3u4m1n for mode 1, no rewind
- /dev/st/c1b2t3u4m2n for mode 2, no rewind
- /dev/st/c1b2t3u4m3n for mode 3, no rewind
-
-
-SCSI CD-ROMs
-
-All SCSI CD-ROMs are placed under /dev/sr. A similar naming
-scheme is used as for SCSI discs. A SCSI CD-ROM with the
-parameters:c=1,b=2,t=3,u=4 would appear as:
-
- /dev/sr/c1b2t3u4
-
-
-SCSI Generic Devices
-
-The generic (aka. raw) interface for all SCSI devices are placed under
-/dev/sg. A similar naming scheme is used as for SCSI discs. A
-SCSI generic device with the parameters:c=1,b=2,t=3,u=4 would appear
-as:
-
- /dev/sg/c1b2t3u4
-
-
-IDE Hard Discs
-
-All IDE discs are placed under /dev/ide/hd, using a similar
-convention to SCSI discs. The following mappings exist between the new
-and the old names:
-
- /dev/hda /dev/ide/hd/c0b0t0u0
- /dev/hdb /dev/ide/hd/c0b0t1u0
- /dev/hdc /dev/ide/hd/c0b1t0u0
- /dev/hdd /dev/ide/hd/c0b1t1u0
-
-
-IDE Tapes
-
-A similar naming scheme is used as for IDE discs. The entries will
-appear in the /dev/ide/mt directory.
-
-IDE CD-ROM
-
-A similar naming scheme is used as for IDE discs. The entries will
-appear in the /dev/ide/cd directory.
-
-IDE Floppies
-
-A similar naming scheme is used as for IDE discs. The entries will
-appear in the /dev/ide/fd directory.
-
-XT Hard Discs
-
-All XT discs are placed under /dev/xd. The first XT disc
-would appear as /dev/xd/c0t0.
-
-
-Old Compatibility Names
-
-The old compatibility names are the legacy device names, such as
-/dev/hda, /dev/sda, /dev/rtc and so on.
-Devfsd can be configured to create compatibility symlinks so that you
-may continue to use the old names in your configuration files and so
-that old applications will continue to function correctly.
-
-In order to configure devfsd to create these legacy names, the
-following lines should be placed in your /etc/devfsd.conf:
-
-REGISTER .* MKOLDCOMPAT
-UNREGISTER .* RMOLDCOMPAT
-
-This will cause devfsd to create (and destroy) symbolic links which
-point to the kernel-supplied names.

-Allocation of Device Numbers
-
-Devfs allows you to write a driver which doesn't need to allocate a
-device number (major&minor numbers) for the internal operation of the
-kernel. However, there are a number of userspace programmes that use
-the device number as a unique handle for a device. An example is the
-find programme, which uses device numbers to determine whether
-an inode is on a different filesystem than another inode. The device
-number used is the one for the block device which a filesystem is
-using. To preserve compatibility with userspace programmes, block
-devices using devfs need to have unique device numbers allocated to
-them. Furthermore, POSIX specifies device numbers, so some kind of
-device number needs to be presented to userspace.
-
-The simplest option (especially when porting drivers to devfs) is to
-keep using the old major and minor numbers. Devfs will take whatever
-values are given for major&minor and pass them onto userspace.
-
-This device number is a 16 bit number, so this leaves plenty of space
-for large numbers of discs and partitions. This scheme can also be
-used for character devices, in particular the tty devices, which are
-currently limited to 256 pseudo-ttys (this limits the total number of
-simultaneous xterms and remote logins). Note that the device number
-is limited to the range 36864-61439 (majors 144-239), in order to
-avoid any possible conflicts with existing official allocations.
-
-Please note that using dynamically allocated block device numbers may
-break the NFS daemons (both user and kernel mode), which expect dev_t
-for a given device to be constant over the lifetime of remote mounts.
-
-A final note on this scheme: since it doesn't increase the size of
-device numbers, there are no compatibility issues with userspace.

-Questions and Answers
-
-
-Making things work
-Alternatives to devfs
-What I don't like about devfs
-How to report bugs
-Strange kernel messages
-Compilation problems with devfsd
-
-
-
-Making things work
-
-Here are some common questions and answers.
-
-
-
-Devfsd doesn't start
-
-Make sure you have compiled and installed devfsd
-Make sure devfsd is being started from your boot
-scripts
-Make sure you have configured your kernel to enable devfs (see
-below)
-Make sure devfs is mounted (see below)
-
-
-Devfsd is not managing all my permissions
-
-Make sure you are capturing the appropriate events. For example,
-device entries created by the kernel generate REGISTER events,
-but those created by devfsd generate CREATE events.
-
-
-Devfsd is not capturing all REGISTER events
-
-See the previous entry: you may need to capture CREATE events.
-
-
-X will not start
-
-Make sure you followed the steps
-outlined above.
-
-
-Why don't my network devices appear in devfs?
-
-This is not a bug. Network devices have their own, completely separate
-namespace. They are accessed via socket(2) and
-setsockopt(2) calls, and thus require no device nodes. I have
-raised the possibilty of moving network devices into the device
-namespace, but have had no response.
-
-
-How can I test if I have devfs compiled into my kernel?
-
-All filesystems built-in or currently loaded are listed in
-/proc/filesystems. If you see a devfs entry, then
-you know that devfs was compiled into your kernel. If you have
-correctly configured and rebuilt your kernel, then devfs will be
-built-in. If you think you've configured it in, but
-/proc/filesystems doesn't show it, you've made a mistake.
-Common mistakes include:
-
-Using a 2.2.x kernel without applying the devfs patch (if you
-don't know how to patch your kernel, use 2.4.x instead, don't bother
-asking me how to patch)
-Forgetting to set CONFIG_EXPERIMENTAL=y
-Forgetting to set CONFIG_DEVFS_FS=y
-Forgetting to set CONFIG_DEVFS_MOUNT=y (if you want devfs
-to be automatically mounted at boot)
-Editing your .config manually, instead of using make
-config or make xconfig
-Forgetting to run make dep; make clean after changing the
-configuration and before compiling
-Forgetting to compile your kernel and modules
-Forgetting to install your kernel
-Forgetting to install your modules
-
-Please check twice that you've done all these steps before sending in
-a bug report.
-
-
-
-How can I test if devfs is mounted on /dev?
-
-The device filesystem will always create an entry called
-".devfsd", which is used to communicate with the daemon. Even
-if the daemon is not running, this entry will exist. Testing for the
-existence of this entry is the approved method of determining if devfs
-is mounted or not. Note that the type of entry (i.e. regular file,
-character device, named pipe, etc.) may change without notice. Only
-the existence of the entry should be relied upon.
-
-
-When I start devfsd, I see the error:
-Error opening file: ".devfsd" No such file or directory?
-
-This means that devfs is not mounted. Make sure you have devfs mounted.
-
-
-How do I mount devfs?
-
-First make sure you have devfs compiled into your kernel (see
-above). Then you will either need to:
-
-set CONFIG_DEVFS_MOUNT=y in your kernel config
-pass devfs=mount to your boot loader
-mount devfs manually in your boot scripts with:
-mount -t none devfs /dev
-
-
-
-Mount by volume LABEL=<label> doesn't work with
-devfs
-
-Most probably you are not mounting devfs onto /dev. What
-happens is that if your kernel config has CONFIG_DEVFS_FS=y
-then the contents of /proc/partitions will have the devfs
-names (such as scsi/host0/bus0/target0/lun0/part1). The
-contents of /proc/partitions are used by mount(8) when
-mounting by volume label. If devfs is not mounted on /dev,
-then mount(8) will fail to find devices. The solution is to
-make sure that devfs is mounted on /dev. See above for how to
-do that.
-
-
-I have extra or incorrect entries in /dev
-
-You may have stale entries in your dev-state area. Check for a
-RESTORE configuration line in your devfsd configuration
-(typically /etc/devfsd.conf). If you have this line, check
-the contents of the specified directory for stale entries. Remove
-any entries which are incorrect, then reboot.
-
-
-I get "Unable to open initial console" messages at boot
-
-This usually happens when you don't have devfs automounted onto
-/dev at boot time, and there is no valid
-/dev/console entry on your root file-system. Create a valid
-/dev/console device node.
-
-
-
-
-
-Alternatives to devfs
-
-I've attempted to collate all the anti-devfs proposals and explain
-their limitations. Under construction.
-
-
-Why not just pass device create/remove events to a daemon?
-
-Here the suggestion is to develop an API in the kernel so that devices
-can register create and remove events, and a daemon listens for those
-events. The daemon would then populate/depopulate /dev (which
-resides on disc).
-
-This has several limitations:
-
-
-it only works for modules loaded and unloaded (or devices inserted
-and removed) after the kernel has finished booting. Without a database
-of events, there is no way the daemon could fully populate
-/dev
-
-
-if you add a database to this scheme, the question is then how to
-present that database to user-space. If you make it a list of strings
-with embedded event codes which are passed through a pipe to the
-daemon, then this is only of use to the daemon. I would argue that the
-natural way to present this data is via a filesystem (since many of
-the events will be of a hierarchical nature), such as devfs.
-Presenting the data as a filesystem makes it easy for the user to see
-what is available and also makes it easy to write scripts to scan the
-"database"
-
-
-the tight binding between device nodes and drivers is no longer
-possible (requiring the otherwise perfectly avoidable
-table lookups)
-
-
-you cannot catch inode lookup events on /dev which means
-that module autoloading requires device nodes to be created. This is a
-problem, particularly for drivers where only a few inodes are created
-from a potentially large set
-
-
-this technique can't be used when the root FS is mounted
-read-only
-
-
-
-
-Just implement a better scsidev
-
-This suggestion involves taking the scsidev programme and
-extending it to scan for all devices, not just SCSI devices. The
-scsidev programme works by scanning /proc/scsi
-
-Problems:
-
-
-the kernel does not currently provide a list of all devices
-available. Not all drivers register entries in /proc or
-generate kernel messages
-
-
-there is no uniform mechanism to register devices other than the
-devfs API
-
-
-implementing such an API is then the same as the
-proposal above
-
-
-
-
-Put /dev on a ramdisc
-
-This suggestion involves creating a ramdisc and populating it with
-device nodes and then mounting it over /dev.
-
-Problems:
-
-
-
-this doesn't help when mounting the root filesystem, since you
-still need a device node to do that
-
-
-if you want to use this technique for the root device node as
-well, you need to use initrd. This complicates the booting sequence
-and makes it significantly harder to administer and configure. The
-initrd is essentially opaque, robbing the system administrator of easy
-configuration
-
-
-insufficient information is available to correctly populate the
-ramdisc. So we come back to the
-proposal above to "solve" this
-
-
-a ramdisc-based solution would take more kernel memory, since the
-backing store would be (at best) normal VFS inodes and dentries, which
-take 284 bytes and 112 bytes, respectively, for each entry. Compare
-that to 72 bytes for devfs
-
-
-
-
-Do nothing: there's no problem
-
-Sometimes people can be heard to claim that the existing scheme is
-fine. This is what they're ignoring:
-
-
-device number size (8 bits each for major and minor) is a real
-limitation, and must be fixed somehow. Systems with large numbers of
-SCSI devices, for example, will continue to consume the remaining
-unallocated major numbers. USB will also need to push beyond the 8 bit
-minor limitation
-
-
-simply increasing the device number size is insufficient. Apart
-from causing a lot of pain, it doesn't solve the management issues
-of a /dev with thousands or more device nodes
-
-
-ignoring the problem of a huge /dev will not make it go
-away, and dismisses the legitimacy of a large number of people who
-want a dynamic /dev
-
-
-the standard response then becomes: "write a device management
-daemon", which brings us back to the
-proposal above
-
-
-
-
-What I don't like about devfs
-
-Here are some common complaints about devfs, and some suggestions and
-solutions that may make it more palatable for you. I can't please
-everybody, but I do try :-)
-
-I hate the naming scheme
-
-First, remember that no naming scheme will please everybody. You hate
-the scheme, others love it. Who's to say who's right and who's wrong?
-Ultimately, the person who writes the code gets to choose, and what
-exists now is a combination of the choices made by the
-devfs author and the
-kernel maintainer (Linus).
-
-However, not all is lost. If you want to create your own naming
-scheme, it is a simple matter to write a standalone script, hack
-devfsd, or write a script called by devfsd. You can create whatever
-naming scheme you like.
-
-Further, if you want to remove all traces of the devfs naming scheme
-from /dev, you can mount devfs elsewhere (say
-/devfs) and populate /dev with links into
-/devfs. This population can be automated using devfsd if you
-wish.
-
-You can even use the VFS binding facility to make the links, rather
-than using symbolic links. This way, you don't even have to see the
-"destination" of these symbolic links.
-
-Devfs puts policy into the kernel
-
-There's already policy in the kernel. Device numbers are in fact
-policy (why should the kernel dictate what device numbers I use?).
-Face it, some policy has to be in the kernel. The real difference
-between device names as policy and device numbers as policy is that
-no one will use device numbers directly, because device
-numbers are devoid of meaning to humans and are ugly. At least with
-the devfs device names, (even though you can add your own naming
-scheme) some people will use the devfs-supplied names directly. This
-offends some people :-)
-
-Devfs is bloatware
-
-This is not even remotely true. As shown above,
-both code and data size are quite modest.
-
-
-How to report bugs
-
-If you have (or think you have) a bug with devfs, please follow the
-steps below:
-
-
-
-make sure you have enabled debugging output when configuring your
-kernel. You will need to set (at least) the following config options:
-
-CONFIG_DEVFS_DEBUG=y
-CONFIG_DEBUG_KERNEL=y
-CONFIG_DEBUG_SLAB=y
-
-
-
-please make sure you have the latest devfs patches applied. The
-latest kernel version might not have the latest devfs patches applied
-yet (Linus is very busy)
-
-
-save a copy of your complete kernel logs (preferably by
-using the dmesg programme) for later inclusion in your bug
-report. You may need to use the -s switch to increase the
-internal buffer size so you can capture all the boot messages.
-Don't edit or trim the dmesg output
-
-
-
-
-try booting with devfs=dall passed to the kernel boot
-command line (read the documentation on your bootloader on how to do
-this), and save the result to a file. This may be quite verbose, and
-it may overflow the messages buffer, but try to get as much of it as
-you can
-
-
-send a copy of your devfsd configuration file(s)
-
-send the bug report to me first.
-Don't expect that I will see it if you post it to the linux-kernel
-mailing list. Include all the information listed above, plus
-anything else that you think might be relevant. Put the string
-devfs somewhere in the subject line, so my mail filters mark
-it as urgent
-
-
-
-
-Here is a general guide on how to ask questions in a way that greatly
-improves your chances of getting a reply:
-
-http://www.tuxedo.org/~esr/faqs/smart-questions.html. If you have
-a bug to report, you should also read
-
-http://www.chiark.greenend.org.uk/~sgtatham/bugs.html.
-
-
-Strange kernel messages
-
-You may see devfs-related messages in your kernel logs. Below are some
-messages and what they mean (and what you should do about them, if
-anything).
-
-
-
-devfs_register(fred): could not append to parent, err: -17
-
-You need to check what the error code means, but usually 17 means
-EEXIST. This means that a driver attempted to create an entry
-fred in a directory, but there already was an entry with that
-name. This is often caused by flawed boot scripts which untar a bunch
-of inodes into /dev, as a way to restore permissions. This
-message is harmless, as the device nodes will still
-provide access to the driver (unless you use the devfs=only
-boot option, which is only for dedicated souls:-). If you want to get
-rid of these annoying messages, upgrade to devfsd-v1.3.20 and use the
-recommended RESTORE directive to restore permissions.
-
-
-devfs_mk_dir(bill): using old entry in dir: c1808724 ""

- Device File System (devfs) Boot Options
-
- Richard Gooch <rgooch@atnf.csiro.au>
-
- 18-AUG-2001
-
-
-When CONFIG_DEVFS_DEBUG is enabled, you can pass several boot options
-to the kernel to debug devfs. The boot options are prefixed by
-"devfs=", and are separated by commas. Spaces are not allowed. The
-syntax looks like this:
-
-devfs=<option1>,<option2>,<option3>
-
-and so on. For example, if you wanted to turn on debugging for module
-load requests and device registration, you would do:
-
-devfs=dmod,dreg
-
-You may prefix "no" to any option. This will invert the option.
-
-
-Debugging Options
-=================
-
-These requires CONFIG_DEVFS_DEBUG to be enabled.
-Note that all debugging options have 'd' as the first character. By
-default all options are off. All debugging output is sent to the
-kernel logs. The debugging options do not take effect until the devfs
-version message appears (just prior to the root filesystem being
-mounted).
-
-These are the options:
-
-dmod print module load requests to <request_module>
-
-dreg print device register requests to <devfs_register>
-
-dunreg print device unregister requests to <devfs_unregister>
-
-dchange print device change requests to <devfs_set_flags>
-
-dilookup print inode lookup requests
-
-diget print VFS inode allocations
-
-diunlink print inode unlinks
-
-dichange print inode changes
-
-dimknod print calls to mknod(2)
-
-dall some debugging turned on
-
-
-Other Options
-=============
-
-These control the default behaviour of devfs. The options are:
-
-mount mount devfs onto /dev at boot time
-
-only disable non-devfs device nodes for devfs-capable drivers

+IRQ-flags state tracing
+
+started by Ingo Molnar <mingo@redhat.com>
+
+the "irq-flags tracing" feature "traces" hardirq and softirq state, in
+that it gives interested subsystems an opportunity to be notified of
+every hardirqs-off/hardirqs-on, softirqs-off/softirqs-on event that
+happens in the kernel.
+
+CONFIG_TRACE_IRQFLAGS_SUPPORT is needed for CONFIG_PROVE_SPIN_LOCKING
+and CONFIG_PROVE_RW_LOCKING to be offered by the generic lock debugging
+code. Otherwise only CONFIG_PROVE_MUTEX_LOCKING and
+CONFIG_PROVE_RWSEM_LOCKING will be offered on an architecture - these
+are locking APIs that are not used in IRQ context. (the one exception
+for rwsems is worked around)
+
+architecture support for this is certainly not in the "trivial"
+category, because lots of lowlevel assembly code deal with irq-flags
+state changes. But an architecture can be irq-flags-tracing enabled in a
+rather straightforward and risk-free manner.
+
+Architectures that want to support this need to do a couple of
+code-organizational changes first:
+
+- move their irq-flags manipulation code from their asm/system.h header
+ to asm/irqflags.h
+
+- rename local_irq_disable()/etc to raw_local_irq_disable()/etc. so that
+ the linux/irqflags.h code can inject callbacks and can construct the
+ real local_irq_disable()/etc APIs.
+
+- add and enable TRACE_IRQFLAGS_SUPPORT in their arch level Kconfig file
+
+and then a couple of functional changes are needed as well to implement
+irq-flags-tracing support:
+
+- in lowlevel entry code add (build-conditional) calls to the
+ trace_hardirqs_off()/trace_hardirqs_on() functions. The lock validator
+ closely guards whether the 'real' irq-flags matches the 'virtual'
+ irq-flags state, and complains loudly (and turns itself off) if the
+ two do not match. Usually most of the time for arch support for
+ irq-flags-tracing is spent in this state: look at the lockdep
+ complaint, try to figure out the assembly code we did not cover yet,
+ fix and repeat. Once the system has booted up and works without a
+ lockdep complaint in the irq-flags-tracing functions arch support is
+ complete.
+- if the architecture has non-maskable interrupts then those need to be
+ excluded from the irq-tracing [and lock validation] mechanism via
+ lockdep_off()/lockdep_on().
+
+in general there is no risk from having an incomplete irq-flags-tracing
+implementation in an architecture: lockdep will detect that and will
+turn itself off. I.e. the lock validator will still be reliable. There
+should be no crashes due to irq-tracing bugs. (except if the assembly
+changes break other code by modifying conditions or registers that
+shouldnt be)

+Runtime locking correctness validator
+=====================================
+
+started by Ingo Molnar <mingo@redhat.com>
+additions by Arjan van de Ven <arjan@linux.intel.com>
+
+Lock-class
+----------
+
+The basic object the validator operates upon is a 'class' of locks.
+
+A class of locks is a group of locks that are logically the same with
+respect to locking rules, even if the locks may have multiple (possibly
+tens of thousands of) instantiations. For example a lock in the inode
+struct is one class, while each inode has its own instantiation of that
+lock class.
+
+The validator tracks the 'state' of lock-classes, and it tracks
+dependencies between different lock-classes. The validator maintains a
+rolling proof that the state and the dependencies are correct.
+
+Unlike an lock instantiation, the lock-class itself never goes away: when
+a lock-class is used for the first time after bootup it gets registered,
+and all subsequent uses of that lock-class will be attached to this
+lock-class.
+
+State
+-----
+
+The validator tracks lock-class usage history into 5 separate state bits:
+
+- 'ever held in hardirq context' [ == hardirq-safe ]
+- 'ever held in softirq context' [ == softirq-safe ]
+- 'ever held with hardirqs enabled' [ == hardirq-unsafe ]
+- 'ever held with softirqs and hardirqs enabled' [ == softirq-unsafe ]
+
+- 'ever used' [ == !unused ]
+
+Single-lock state rules:
+------------------------
+
+A softirq-unsafe lock-class is automatically hardirq-unsafe as well. The
+following states are exclusive, and only one of them is allowed to be
+set for any lock-class:
+
+ <hardirq-safe> and <hardirq-unsafe>
+ <softirq-safe> and <softirq-unsafe>
+
+The validator detects and reports lock usage that violate these
+single-lock state rules.
+
+Multi-lock dependency rules:
+----------------------------
+
+The same lock-class must not be acquired twice, because this could lead
+to lock recursion deadlocks.
+
+Furthermore, two locks may not be taken in different order:
+
+ <L1> -> <L2>
+ <L2> -> <L1>
+
+because this could lead to lock inversion deadlocks. (The validator
+finds such dependencies in arbitrary complexity, i.e. there can be any
+other locking sequence between the acquire-lock operations, the
+validator will still track all dependencies between locks.)
+
+Furthermore, the following usage based lock dependencies are not allowed
+between any two lock-classes:
+
+ <hardirq-safe> -> <hardirq-unsafe>
+ <softirq-safe> -> <softirq-unsafe>
+
+The first rule comes from the fact the a hardirq-safe lock could be
+taken by a hardirq context, interrupting a hardirq-unsafe lock - and
+thus could result in a lock inversion deadlock. Likewise, a softirq-safe
+lock could be taken by an softirq context, interrupting a softirq-unsafe
+lock.
+
+The above rules are enforced for any locking sequence that occurs in the
+kernel: when acquiring a new lock, the validator checks whether there is
+any rule violation between the new lock and any of the held locks.
+
+When a lock-class changes its state, the following aspects of the above
+dependency rules are enforced:
+
+- if a new hardirq-safe lock is discovered, we check whether it
+ took any hardirq-unsafe lock in the past.
+
+- if a new softirq-safe lock is discovered, we check whether it took
+ any softirq-unsafe lock in the past.
+
+- if a new hardirq-unsafe lock is discovered, we check whether any
+ hardirq-safe lock took it in the past.
+
+- if a new softirq-unsafe lock is discovered, we check whether any
+ softirq-safe lock took it in the past.
+
+(Again, we do these checks too on the basis that an interrupt context
+could interrupt _any_ of the irq-unsafe or hardirq-unsafe locks, which
+could lead to a lock inversion deadlock - even if that lock scenario did
+not trigger in practice yet.)
+
+Exception: Nested data dependencies leading to nested locking
+-------------------------------------------------------------
+
+There are a few cases where the Linux kernel acquires more than one
+instance of the same lock-class. Such cases typically happen when there
+is some sort of hierarchy within objects of the same type. In these
+cases there is an inherent "natural" ordering between the two objects
+(defined by the properties of the hierarchy), and the kernel grabs the
+locks in this fixed order on each of the objects.
+
+An example of such an object hieararchy that results in "nested locking"
+is that of a "whole disk" block-dev object and a "partition" block-dev
+object; the partition is "part of" the whole device and as long as one
+always takes the whole disk lock as a higher lock than the partition
+lock, the lock ordering is fully correct. The validator does not
+automatically detect this natural ordering, as the locking rule behind
+the ordering is not static.
+
+In order to teach the validator about this correct usage model, new
+versions of the various locking primitives were added that allow you to
+specify a "nesting level". An example call, for the block device mutex,
+looks like this:
+
+enum bdev_bd_mutex_lock_class
+{
+ BD_MUTEX_NORMAL,
+ BD_MUTEX_WHOLE,
+ BD_MUTEX_PARTITION
+};
+
+ mutex_lock_nested(&bdev->bd_contains->bd_mutex, BD_MUTEX_PARTITION);
+
+In this case the locking is done on a bdev object that is known to be a
+partition.
+
+The validator treats a lock that is taken in such a nested fasion as a
+separate (sub)class for the purposes of validation.
+
+Note: When changing code to use the _nested() primitives, be careful and
+check really thoroughly that the hiearchy is correctly mapped; otherwise
+you can get false positives or false negatives.
+
+Proof of 100% correctness:
+--------------------------
+
+The validator achieves perfect, mathematical 'closure' (proof of locking
+correctness) in the sense that for every simple, standalone single-task
+locking sequence that occured at least once during the lifetime of the
+kernel, the validator proves it with a 100% certainty that no
+combination and timing of these locking sequences can cause any class of
+lock related deadlock. [*]
+
+I.e. complex multi-CPU and multi-task locking scenarios do not have to
+occur in practice to prove a deadlock: only the simple 'component'
+locking chains have to occur at least once (anytime, in any
+task/context) for the validator to be able to prove correctness. (For
+example, complex deadlocks that would normally need more than 3 CPUs and
+a very unlikely constellation of tasks, irq-contexts and timings to
+occur, can be detected on a plain, lightly loaded single-CPU system as
+well!)
+
+This radically decreases the complexity of locking related QA of the
+kernel: what has to be done during QA is to trigger as many "simple"
+single-task locking dependencies in the kernel as possible, at least
+once, to prove locking correctness - instead of having to trigger every
+possible combination of locking interaction between CPUs, combined with
+every possible hardirq and softirq nesting scenario (which is impossible
+to do in practice).
+
+[*] assuming that the validator itself is 100% correct, and no other
+ part of the system corrupts the state of the validator in any way.
+ We also assume that all NMI/SMM paths [which could interrupt
+ even hardirq-disabled codepaths] are correct and do not interfere
+ with the validator. We also assume that the 64-bit 'chain hash'
+ value is unique for every lock-chain in the system. Also, lock
+ recursion must not be higher than 20.
+
+Performance:
+------------
+
+The above rules require _massive_ amounts of runtime checking. If we did
+that for every lock taken and for every irqs-enable event, it would
+render the system practically unusably slow. The complexity of checking
+is O(N^2), so even with just a few hundred lock-classes we'd have to do
+tens of thousands of checks for every event.
+
+This problem is solved by checking any given 'locking scenario' (unique
+sequence of locks taken after each other) only once. A simple stack of
+held locks is maintained, and a lightweight 64-bit hash value is
+calculated, which hash is unique for every lock chain. The hash value,
+when the chain is validated for the first time, is then put into a hash
+table, which hash-table can be checked in a lockfree manner. If the
+locking chain occurs again later on, the hash table tells us that we
+dont have to validate the chain again.

+/proc/sys/net/ipv4/vs/* Variables:
+
+am_droprate - INTEGER
+ default 10
+
+ It sets the always mode drop rate, which is used in the mode 3
+ of the drop_rate defense.
+
+amemthresh - INTEGER
+ default 1024
+
+ It sets the available memory threshold (in pages), which is
+ used in the automatic modes of defense. When there is no
+ enough available memory, the respective strategy will be
+ enabled and the variable is automatically set to 2, otherwise
+ the strategy is disabled and the variable is set to 1.
+
+cache_bypass - BOOLEAN
+ 0 - disabled (default)
+ not 0 - enabled
+
+ If it is enabled, forward packets to the original destination
+ directly when no cache server is available and destination
+ address is not local (iph->daddr is RTN_UNICAST). It is mostly
+ used in transparent web cache cluster.
+
+debug_level - INTEGER
+ 0 - transmission error messages (default)
+ 1 - non-fatal error messages
+ 2 - configuration
+ 3 - destination trash
+ 4 - drop entry
+ 5 - service lookup
+ 6 - scheduling
+ 7 - connection new/expire, lookup and synchronization
+ 8 - state transition
+ 9 - binding destination, template checks and applications
+ 10 - IPVS packet transmission
+ 11 - IPVS packet handling (ip_vs_in/ip_vs_out)
+ 12 or more - packet traversal
+
+ Only available when IPVS is compiled with the CONFIG_IPVS_DEBUG
+
+ Higher debugging levels include the messages for lower debugging
+ levels, so setting debug level 2, includes level 0, 1 and 2
+ messages. Thus, logging becomes more and more verbose the higher
+ the level.
+
+drop_entry - INTEGER
+ 0 - disabled (default)
+
+ The drop_entry defense is to randomly drop entries in the
+ connection hash table, just in order to collect back some
+ memory for new connections. In the current code, the
+ drop_entry procedure can be activated every second, then it
+ randomly scans 1/32 of the whole and drops entries that are in
+ the SYN-RECV/SYNACK state, which should be effective against
+ syn-flooding attack.
+
+ The valid values of drop_entry are from 0 to 3, where 0 means
+ that this strategy is always disabled, 1 and 2 mean automatic
+ modes (when there is no enough available memory, the strategy
+ is enabled and the variable is automatically set to 2,
+ otherwise the strategy is disabled and the variable is set to
+ 1), and 3 means that that the strategy is always enabled.
+
+drop_packet - INTEGER
+ 0 - disabled (default)
+
+ The drop_packet defense is designed to drop 1/rate packets
+ before forwarding them to real servers. If the rate is 1, then
+ drop all the incoming packets.
+
+ The value definition is the same as that of the drop_entry. In
+ the automatic mode, the rate is determined by the follow
+ formula: rate = amemthresh / (amemthresh - available_memory)
+ when available memory is less than the available memory
+ threshold. When the mode 3 is set, the always mode drop rate
+ is controlled by the /proc/sys/net/ipv4/vs/am_droprate.
+
+expire_nodest_conn - BOOLEAN
+ 0 - disabled (default)
+ not 0 - enabled
+
+ The default value is 0, the load balancer will silently drop
+ packets when its destination server is not available. It may
+ be useful, when user-space monitoring program deletes the
+ destination server (because of server overload or wrong
+ detection) and add back the server later, and the connections
+ to the server can continue.
+
+ If this feature is enabled, the load balancer will expire the
+ connection immediately when a packet arrives and its
+ destination server is not available, then the client program
+ will be notified that the connection is closed. This is
+ equivalent to the feature some people requires to flush
+ connections when its destination is not available.
+
+expire_quiescent_template - BOOLEAN
+ 0 - disabled (default)
+ not 0 - enabled
+
+ When set to a non-zero value, the load balancer will expire
+ persistent templates when the destination server is quiescent.
+ This may be useful, when a user makes a destination server
+ quiescent by setting its weight to 0 and it is desired that
+ subsequent otherwise persistent connections are sent to a
+ different destination server. By default new persistent
+ connections are allowed to quiescent destination servers.
+
+ If this feature is enabled, the load balancer will expire the
+ persistence template if it is to be used to schedule a new
+ connection and the destination server is quiescent.
+
+nat_icmp_send - BOOLEAN
+ 0 - disabled (default)
+ not 0 - enabled
+
+ It controls sending icmp error messages (ICMP_DEST_UNREACH)
+ for VS/NAT when the load balancer receives packets from real
+ servers but the connection entries don't exist.
+
+secure_tcp - INTEGER
+ 0 - disabled (default)
+
+ The secure_tcp defense is to use a more complicated state
+ transition table and some possible short timeouts of each
+ state. In the VS/NAT, it delays the entering the ESTABLISHED
+ until the real server starts to send data and ACK packet
+ (after 3-way handshake).
+
+ The value definition is the same as that of drop_entry or
+ drop_packet.
+
+sync_threshold - INTEGER
+ default 3
+
+ It sets synchronization threshold, which is the minimum number
+ of incoming packets that a connection needs to receive before
+ the connection will be synchronized. A connection will be
+ synchronized, every time the number of its incoming packets
+ modulus 50 equals the threshold. The range of the threshold is
+ from 0 to 49.

-Envinronmental monitoring:
+Pretimeouts:
+
+Some watchdog timers can be set to have a trigger go off before the

+the pretimeout. So, for instance, if you set the timeout to 60 seconds
+and the pretimeout to 10 seconds, the pretimout will go of in 50
+seconds. Setting a pretimeout to zero disables it.
+
+There is also a get function for getting the pretimeout:

+
+Not all watchdog drivers will support a pretimeout.

+config ROM
+ bool "Specify ROM linker regions"

+ Define a ROM region for the linker script. This creates a kernel

+ regions being copied out to RAM at startup.
+
+config ROMBASE
+ hex "Address of the base of ROM device"
+ default "0"
+ depends on ROM
+ help
+ Define the address that the ROM region starts at. Some platforms
+ use this to set their chip select region accordingly for the boot
+ device.
+
+config ROMVEC
+ hex "Address of the base of the ROM vectors"
+ default "0"
+ depends on ROM
+ help
+ This is almost always the same as the base of the ROM. Since on all
+ 68000 type varients the vectors are at the base of the boot device
+ on system startup.
+
+config ROMVECSIZE
+ hex "Size of ROM vector region (in bytes)"
+ default "0x400"
+ depends on ROM
+ help
+ Define the size of the vector region in ROM. For most 68000
+ varients this would be 0x400 bytes in size. Set to 0 if you do
+ not want a vector region at the start of the ROM.
+
+config ROMSTART
+ hex "Address of the base of system image in ROM"
+ default "0x400"
+ depends on ROM
+ help
+ Define the start address of the system image in ROM. Commonly this
+ is strait after the ROM vectors.
+
+config ROMSIZE
+ hex "Size of the ROM device"
+ default "0x100000"
+ depends on ROM

+ Size of the ROM device. On some platforms this is used to setup

+ * Copyright (C) 2006 Red Hat, Inc., Ingo Molnar <mingo@redhat.com>
+ *
+ * this code maps all the lock dependencies as they occur in a live kernel
+ * and will warn about the following classes of locking bugs:
+ *
+ * - lock inversion scenarios
+ * - circular lock dependencies
+ * - hardirq/softirq safe/unsafe locking bugs
+ *
+ * Bugs are reported even if the current locking scenario does not cause
+ * any deadlock at this point.
+ *
+ * I.e. if anytime in the past two locks were taken in a different order,
+ * even if it happened for another task, even if those were different
+ * locks (but of the same class as this lock), this code will detect it.
+ *
+ * Thanks to Arjan van de Ven for coming up with the initial idea of
+ * mapping lock dependencies runtime.

+ This feature enables the kernel to prove that all locking

+ sequences (on an arbitrary number of CPUs, running an
+ arbitrary number of tasks and interrupt contexts) cause a
+ deadlock.
+
+ In short, this feature enables the kernel to report locking
+ related deadlocks before they actually occur.
+
+ The proof does not depend on how hard and complex a
+ deadlock scenario would be to trigger: how many
+ participant CPUs, tasks and irq-contexts would be needed
+ for it to trigger. The proof also does not depend on
+ timing: if a race and a resulting deadlock is possible
+ theoretically (no matter how unlikely the race scenario
+ is), it will be proven so and will immediately be
+ reported by the kernel (once the event is observed that
+ makes the deadlock theoretically possible).
+
+ If a deadlock is impossible (i.e. the locking rules, as
+ observed by the kernel, are mathematically correct), the
+ kernel reports nothing.
+
+ NOTE: this feature can also be enabled for rwlocks, mutexes
+ and rwsems - in which case all dependencies between these
+ different locking variants are observed and mapped too, and
+ the proof of observed correctness is also maintained for an
+ arbitrary combination of these separate locking variants.

+
+ Here's a block diagram of how most of the cards work:
+
+ +-----------+
+ record | |<-------------------- Inputs
+ <-------| | |
+ PCI | Transport | |
+ bus | engine | \|/
+ ------->| | +-------+
+ play | |--->|monitor|-------> Outputs
+ +-----------+ | mixer |
+ +-------+
+
+ The lines going to and from the PCI bus represent "pipes". A pipe performs
+ audio transport - moving audio data to and from buffers on the host via
+ bus mastering.
+
+ The inputs and outputs on the right represent input and output "busses."
+ A bus is a physical, real connection to the outside world. An example
+ of a bus would be the 1/4" analog connectors on the back of Layla or
+ an RCA S/PDIF connector.
+
+ For most cards, there is a one-to-one correspondence between outputs
+ and busses; that is, each individual pipe is hard-wired to a single bus.
+
+ Cards that work this way are Darla20, Gina20, Layla20, Darla24, Gina24,
+ Layla24, Mona, and Indigo.
+
+
+ Mia has a feature called "virtual outputs."
+
+
+ +-----------+
+ record | |<----------------------------- Inputs
+ <-------| | |
+ PCI | Transport | |
+ bus | engine | \|/
+ ------->| | +------+ +-------+
+ play | |-->|vmixer|-->|monitor|-------> Outputs
+ +-----------+ +------+ | mixer |
+ +-------+
+
+
+ Obviously, the difference here is the box labeled "vmixer." Vmixer is
+ short for "virtual output mixer." For Mia, pipes are *not* hard-wired
+ to a single bus; the vmixer lets you mix any pipe to any bus in any
+ combination.
+
+ Note, however, that the left-hand side of the diagram is unchanged.
+ Transport works exactly the same way - the difference is in the mixer stage.
+
+
+ Pipes and busses are numbered starting at zero.
+
+
+
+ Pipe index
+ ==========
+
+ A number of calls in CEchoGals refer to a "pipe index". A pipe index is
+ a unique number for a pipe that unambiguously refers to a playback or record
+ pipe. Pipe indices are numbered starting with analog outputs, followed by
+ digital outputs, then analog inputs, then digital inputs.
+
+ Take Gina24 as an example:
+
+ Pipe index

+ You get the pipe index by calling CEchoGals::OpenAudio; the other transport
+ functions take the pipe index as a parameter. If you need a pipe index for
+ some other reason, use the handy Makepipe_index method.
+
+
+ Some calls take a CChannelMask parameter; CChannelMask is a handy way to
+ group pipe indices.
+
+
+
+ Digital mode switch
+ ===================
+
+ Some cards (right now, Gina24, Layla24, and Mona) have a Digital Mode Switch
+ or DMS. Cards with a DMS can be set to one of three mutually exclusive
+ digital modes: S/PDIF RCA, S/PDIF optical, or ADAT optical.
+
+ This may create some confusion since ADAT optical is 8 channels wide and
+ S/PDIF is only two channels wide. Gina24, Layla24, and Mona handle this
+ by acting as if they always have 8 digital outs and ins. If you are in
+ either S/PDIF mode, the last 6 channels don't do anything - data sent
+ out these channels is thrown away and you will always record zeros.
+
+ Note that with Gina24, Layla24, and Mona, sample rates above 50 kHz are
+ only available if you have the card configured for S/PDIF optical or S/PDIF
+ RCA.
+
+
+
+ Double speed mode
+ =================
+
+ Some of the cards support 88.2 kHz and 96 kHz sampling (Darla24, Gina24,
+ Layla24, Mona, Mia, and Indigo). For these cards, the driver sometimes has
+ to worry about "double speed mode"; double speed mode applies whenever the
+ sampling rate is above 50 kHz.
+
+ For instance, Mona and Layla24 support word clock sync. However, they
+ actually support two different word clock modes - single speed (below
+ 50 kHz) and double speed (above 50 kHz). The hardware detects if a single
+ or double speed word clock signal is present; the generic code uses that
+ information to determine which mode to use.
+
+ The generic code takes care of all this for you.

+
+Setting the sample rates on Layla24 is somewhat schizophrenic.
+
+For standard rates, it works exactly like Mona and Gina24. That is, for
+8, 11.025, 16, 22.05, 32, 44.1, 48, 88.2, and 96 kHz, you just set the
+appropriate bits in the control register and write the control register.
+
+In order to support MIDI time code sync (and possibly SMPTE LTC sync in
+the future), Layla24 also has "continuous sample rate mode". In this mode,
+Layla24 can generate any sample rate between 25 and 50 kHz inclusive, or
+50 to 100 kHz inclusive for double speed mode.
+
+To use continuous mode:
+
+-Set the clock select bits in the control register to 0xe (see the #define
+ below)
+
+-Set double-speed mode if you want to use sample rates above 50 kHz
+
+-Write the control register as you would normally
+
+-Now, you need to set the frequency register. First, you need to determine the
+ value for the frequency register. This is given by the following formula:
+
+frequency_reg = (LAYLA24_MAGIC_NUMBER / sample_rate) - 2
+
+Note the #define below for the magic number
+
+-Wait for the DSP handshake
+-Write the frequency_reg value to the .SampleRate field of the comm page
+-Send the vector command SET_LAYLA24_FREQUENCY_REG (see vmonkey.h)
+
+Once you have set the control register up for continuous mode, you can just
+write the frequency register to change the sample rate. This could be
+used for MIDI time code sync. For MTC sync, the control register is set for
+continuous mode. The driver then just keeps writing the
+SET_LAYLA24_FREQUENCY_REG command.
