-===================
-NFS Fault Injection
-===================
-
-Fault injection is a method for forcing errors that may not normally occur, or
-may be difficult to reproduce. Forcing these errors in a controlled environment
-can help the developer find and fix bugs before their code is shipped in a
-production system. Injecting an error on the Linux NFS server will allow us to
-observe how the client reacts and if it manages to recover its state correctly.
-
-NFSD_FAULT_INJECTION must be selected when configuring the kernel to use this
-feature.
-
-
-Using Fault Injection
-=====================
-On the client, mount the fault injection server through NFS v4.0+ and do some
-work over NFS (open files, take locks, ...).
-
-On the server, mount the debugfs filesystem to <debug_dir> and ls
-<debug_dir>/nfsd. This will show a list of files that will be used for
-injecting faults on the NFS server. As root, write a number n to the file
-corresponding to the action you want the server to take. The server will then
-process the first n items it finds. So if you want to forget 5 locks, echo '5'
-to <debug_dir>/nfsd/forget_locks. A value of 0 will tell the server to forget
-all corresponding items. A log message will be created containing the number
-of items forgotten (check dmesg).
-
-Go back to work on the client and check if the client recovered from the error
-correctly.
-
-
-Available Faults
-================
-forget_clients:
- The NFS server keeps a list of clients that have placed a mount call. If
- this list is cleared, the server will have no knowledge of who the client
- is, forcing the client to reauthenticate with the server.
-
-forget_openowners:
- The NFS server keeps a list of what files are currently opened and who
- they were opened by. Clearing this list will force the client to reopen
- its files.
-
-forget_locks:
- The NFS server keeps a list of what files are currently locked in the VFS.
- Clearing this list will force the client to reclaim its locks (files are
- unlocked through the VFS as they are cleared from this list).
-
-forget_delegations:
- A delegation is used to assure the client that a file, or part of a file,
- has not changed since the delegation was awarded. Clearing this list will
- force the client to reacquire its delegation before accessing the file
- again.
-
-recall_delegations:
- Delegations can be recalled by the server when another client attempts to
- access a file. This test will notify the client that its delegation has
- been revoked, forcing the client to reacquire the delegation before using
- the file again.
-
-
-tools/nfs/inject_faults.sh script
-=================================
-This script has been created to ease the fault injection process. This script
-will detect the mounted debugfs directory and write to the files located there
-based on the arguments passed by the user. For example, running
-`inject_faults.sh forget_locks 1` as root will instruct the server to forget
-one lock. Running `inject_faults forget_locks` will instruct the server to
-forgetall locks.

+description: |
+ The TI K3 family of SoCs usually have one or more dual-core Arm Cortex R5F
+ processor subsystems/clusters (R5FSS). The dual core cluster can be used
+ either in a LockStep mode providing safety/fault tolerance features or in a
+ Split mode providing two individual compute cores for doubling the compute
+ capacity. These are used together with other processors present on the SoC
+ to achieve various system level goals.
+
+ Each Dual-Core R5F sub-system is represented as a single DTS node
+ representing the cluster, with a pair of child DT nodes representing
+ the individual R5F cores. Each node has a number of required or optional
+ properties that enable the OS running on the host processor to perform
+ the device management of the remote processor and to communicate with the
+ remote processor.

+ The R5F Sub-System device node should define two R5F child nodes, each
+ node representing a TI instantiation of the Arm Cortex R5F core. There
+ are some specific integration differences for the IP like the usage of
+ a Region Address Translator (RAT) for translating the larger SoC bus
+ addresses into a 32-bit address space for the processor.
+
+ Each R5F core has an associated 64 KB of Tightly-Coupled Memory (TCM)
+ internal memories split between two banks - TCMA and TCMB (further
+ interleaved into two banks TCMB0 and TCMB1). These memories (also called
+ ATCM and BTCM) provide read/write performance on par with the core's L1
+ caches. Each of the TCMs can be enabled or disabled independently and
+ either of them can be configured to appear at that R5F's address 0x0.
+
+ The cores do not use an MMU, but has a Region Address Translater
+ (RAT) module that is accessible only from the R5Fs for providing
+ translations between 32-bit CPU addresses into larger system bus
+ addresses. Cache and memory access settings are provided through a
+ Memory Protection Unit (MPU), programmable only from the R5Fs.

+
+description: |+
+
+ The Programmable Real-Time Unit and Industrial Communication Subsystem
+ (PRU-ICSS a.k.a. PRUSS) is present on various TI SoCs such as AM335x, AM437x,
+ Keystone 66AK2G, OMAP-L138/DA850 etc. A PRUSS consists of dual 32-bit RISC
+ cores (Programmable Real-Time Units, or PRUs), shared RAM, data and
+ instruction RAMs, some internal peripheral modules to facilitate industrial
+ communication, and an interrupt controller.
+
+ The programmable nature of the PRUs provide flexibility to implement custom
+ peripheral interfaces, fast real-time responses, or specialized data handling.
+ The common peripheral modules include the following,
+ - an Ethernet MII_RT module with two MII ports
+ - an MDIO port to control external Ethernet PHYs
+ - an Industrial Ethernet Peripheral (IEP) to manage/generate Industrial
+ Ethernet functions
+ - an Enhanced Capture Module (eCAP)
+ - an Industrial Ethernet Timer with 7/9 capture and 16 compare events
+ - a 16550-compatible UART to support PROFIBUS
+ - Enhanced GPIO with async capture and serial support
+
+ A PRU-ICSS subsystem can have up to three shared data memories. A PRU core
+ acts on a primary Data RAM (there are usually 2 Data RAMs) at its address
+ 0x0, but also has access to a secondary Data RAM (primary to the other PRU
+ core) at its address 0x2000. A shared Data RAM, if present, can be accessed
+ by both the PRU cores. The Interrupt Controller (INTC) and a CFG module are
+ common to both the PRU cores. Each PRU core also has a private instruction
+ RAM, and specific register spaces for Control and Debug functionalities.
+
+ Various sub-modules within a PRU-ICSS subsystem are represented as individual
+ nodes and are defined using a parent-child hierarchy depending on their
+ integration within the IP and the SoC. These nodes are described in the
+ following sections.
+
+
+ PRU-ICSS Node
+ ==============
+ Each PRU-ICSS instance is represented as its own node with the individual PRU
+ processor cores, the memories node, an INTC node and an MDIO node represented
+ as child nodes within this PRUSS node. This node shall be a child of the
+ corresponding interconnect bus nodes or target-module nodes.
+
+ See ../../mfd/syscon.yaml for generic SysCon binding details.

+JBD2 to also allows you to perform file-system specific delta commits known as
+fast commits. In order to use fast commits, you first need to call
+:c:func:`jbd2_fc_init` and tell how many blocks at the end of journal
+area should be reserved for fast commits. Along with that, you will also need
+to set following callbacks that perform correspodning work:
+
+`journal->j_fc_cleanup_cb`: Cleanup function called after every full commit and
+fast commit.
+
+`journal->j_fc_replay_cb`: Replay function called for replay of fast commit
+blocks.
+
+File system is free to perform fast commits as and when it wants as long as it
+gets permission from JBD2 to do so by calling the function
+:c:func:`jbd2_fc_begin_commit()`. Once a fast commit is done, the client
+file system should tell JBD2 about it by calling
+:c:func:`jbd2_fc_end_commit()`. If file system wants JBD2 to perform a full
+commit immediately after stopping the fast commit it can do so by calling
+:c:func:`jbd2_fc_end_commit_fallback()`. This is useful if fast commit operation
+fails for some reason and the only way to guarantee consistency is for JBD2 to
+perform the full traditional commit.
+
+JBD2 helper functions to manage fast commit buffers. File system can use
+:c:func:`jbd2_fc_get_buf()` and :c:func:`jbd2_fc_wait_bufs()` to allocate
+and wait on IO completion of fast commit buffers.
+
+Currently, only Ext4 implements fast commits. For details of its implementation
+of fast commits, please refer to the top level comments in
+fs/ext4/fast_commit.c.

+================================
+Linux I2C slave testunit backend
+================================
+
+by Wolfram Sang <wsa@sang-engineering.com> in 2020
+
+This backend can be used to trigger test cases for I2C bus masters which
+require a remote device with certain capabilities (and which are usually not so
+easy to obtain). Examples include multi-master testing, and SMBus Host Notify
+testing. For some tests, the I2C slave controller must be able to switch
+between master and slave mode because it needs to send data, too.
+
+Note that this is a device for testing and debugging. It should not be enabled
+in a production build. And while there is some versioning and we try hard to
+keep backward compatibility, there is no stable ABI guaranteed!
+
+Instantiating the device is regular. Example for bus 0, address 0x30:
+
+# echo "slave-testunit 0x1030" > /sys/bus/i2c/devices/i2c-0/new_device
+
+After that, you will have a write-only device listening. Reads will just return
+an 8-bit version number of the testunit. When writing, the device consists of 4
+8-bit registers and all must be written to start a testcase, i.e. you must
+always write 4 bytes to the device. The registers are:
+
+0x00 CMD - which test to trigger
+0x01 DATAL - configuration byte 1 for the test
+0x02 DATAH - configuration byte 2 for the test
+0x03 DELAY - delay in n * 10ms until test is started
+
+Using 'i2cset' from the i2c-tools package, the generic command looks like:
+
+# i2cset -y <bus_num> <testunit_address> <CMD> <DATAL> <DATAH> <DELAY> i
+
+DELAY is a generic parameter which will delay the execution of the test in CMD.
+While a command is running (including the delay), new commands will not be
+acknowledged. You need to wait until the old one is completed.
+
+The commands are described in the following section. An invalid command will
+result in the transfer not being acknowledged.
+
+Commands
+--------
+
+0x00 NOOP (reserved for future use)
+
+0x01 READ_BYTES (also needs master mode)
+ DATAL - address to read data from (lower 7 bits, highest bit currently unused)
+ DATAH - number of bytes to read
+
+This is useful to test if your bus master driver is handling multi-master
+correctly. You can trigger the testunit to read bytes from another device on
+the bus. If the bus master under test also wants to access the bus at the same
+time, the bus will be busy. Example to read 128 bytes from device 0x50 after
+50ms of delay:
+
+# i2cset -y 0 0x30 0x01 0x50 0x80 0x05 i
+
+0x02 SMBUS_HOST_NOTIFY (also needs master mode)
+ DATAL - low byte of the status word to send
+ DATAH - high byte of the status word to send
+
+This test will send an SMBUS_HOST_NOTIFY message to the host. Note that the
+status word is currently ignored in the Linux Kernel. Example to send a
+notification after 10ms:
+
+# i2cset -y 0 0x30 0x02 0x42 0x64 0x01 i

+
+ If no filter range matches an MSR index that is getting accessed, KVM will
+ fall back to rejecting access to the MSR. In this mode, all MSRs that should
+ be processed by KVM need to explicitly be marked as allowed in the bitmaps.
+
+This ioctl allows user space to define up to 16 bitmaps of MSR ranges to
+specify whether a certain MSR access should be explicitly filtered for or not.
+
+If this ioctl has never been invoked, MSR accesses are not guarded and the
+default KVM in-kernel emulation behavior is fully preserved.
+
+Calling this ioctl with an empty set of ranges (all nmsrs == 0) disables MSR
+filtering. In that mode, ``KVM_MSR_FILTER_DEFAULT_DENY`` is invalid and causes
+an error.
+
+As soon as the filtering is in place, every MSR access is processed through
+the filtering except for accesses to the x2APIC MSRs (from 0x800 to 0x8ff);
+x2APIC MSRs are always allowed, independent of the ``default_allow`` setting,
+and their behavior depends on the ``X2APIC_ENABLE`` bit of the APIC base
+register.
+
+If a bit is within one of the defined ranges, read and write accesses are
+guarded by the bitmap's value for the MSR index if the kind of access
+is included in the ``struct kvm_msr_filter_range`` flags. If no range
+cover this particular access, the behavior is determined by the flags
+field in the kvm_msr_filter struct: ``KVM_MSR_FILTER_DEFAULT_ALLOW``
+and ``KVM_MSR_FILTER_DEFAULT_DENY``.
+
+Each bitmap range specifies a range of MSRs to potentially allow access on.
+The range goes from MSR index [base .. base+nmsrs]. The flags field
+indicates whether reads, writes or both reads and writes are filtered
+by setting a 1 bit in the bitmap for the corresponding MSR index.
+
+If an MSR access is not permitted through the filtering, it generates a
+#GP inside the guest. When combined with KVM_CAP_X86_USER_SPACE_MSR, that
+allows user space to deflect and potentially handle various MSR accesses
+into user space.
+
+If a vCPU is in running state while this ioctl is invoked, the vCPU may

+1.3 ATTRIBUTE: KVM_ARM_VCPU_PMU_V3_FILTER
+-----------------------------------------

+ pointer to a struct kvm_pmu_event_filter
+
+:Returns:

+ ======= ======================================================
+ -ENODEV PMUv3 not supported or GIC not initialized

+ configured as required prior to calling this attribute
+ -EBUSY PMUv3 already initialized
+ -EINVAL Invalid filter range
+ ======= ======================================================
+
+Request the installation of a PMU event filter described as follows::
+
+ struct kvm_pmu_event_filter {
+ __u16 base_event;
+ __u16 nevents;
+
+ #define KVM_PMU_EVENT_ALLOW 0
+ #define KVM_PMU_EVENT_DENY 1
+
+ __u8 action;
+ __u8 pad[3];
+ };
+
+A filter range is defined as the range [@base_event, @base_event + @nevents),
+together with an @action (KVM_PMU_EVENT_ALLOW or KVM_PMU_EVENT_DENY). The
+first registered range defines the global policy (global ALLOW if the first
+@action is DENY, global DENY if the first @action is ALLOW). Multiple ranges
+can be programmed, and must fit within the event space defined by the PMU
+architecture (10 bits on ARMv8.0, 16 bits from ARMv8.1 onwards).
+
+Note: "Cancelling" a filter by registering the opposite action for the same
+range doesn't change the default action. For example, installing an ALLOW
+filter for event range [0:10) as the first filter and then applying a DENY
+action for the same range will leave the whole range as disabled.
+
+Restrictions: Event 0 (SW_INCR) is never filtered, as it doesn't count a
+hardware event. Filtering event 0x1E (CHAIN) has no effect either, as it
+isn't strictly speaking an event. Filtering the cycle counter is possible
+using event 0x11 (CPU_CYCLES).

- Support for EZchip development platforms,
- based on ARC700 cores.
- We handle few flavors:
- - Hardware Emulator AKA HE which is FPGA based chassis
- - Simulator based on MetaWare nSIM
- - NPS400 chip based on ASIC
-
-config EZNPS_MTM_EXT
- bool "ARC-EZchip MTM Extensions"
- select CPUMASK_OFFSTACK
- depends on ARC_PLAT_EZNPS && SMP
- default y
- help
- Here we add new hierarchy for CPUs topology.
- We got:
- Core
- Thread
- At the new thread level each CPU represent one HW thread.
- At highest hierarchy each core contain 16 threads,
- any of them seem like CPU from Linux point of view.
- All threads within same core share the execution unit of the
- core and HW scheduler round robin between them.
-
-config EZNPS_MEM_ERROR_ALIGN
- bool "ARC-EZchip Memory error as an exception"
- depends on EZNPS_MTM_EXT
- default n
- help
- On the real chip of the NPS, user memory errors are handled
- as a machine check exception, which is fatal, whereas on
- simulator platform for NPS, is handled as a Level 2 interrupt
- (just a stock ARC700) which is recoverable. This option makes
- simulator behave like hardware.
-
-config EZNPS_SHARED_AUX_REGS
- bool "ARC-EZchip Shared Auxiliary Registers Per Core"
- depends on ARC_PLAT_EZNPS
- default y
- help
- On the real chip of the NPS, auxiliary registers are shared between
- all the cpus of the core, whereas on simulator platform for NPS,
- each cpu has a different set of auxiliary registers. Configuration
- should be unset if auxiliary registers are not shared between the cpus
- of the core, so there will be a need to initialize them per cpu.

+/* The read-ahead cache present in the Brahma-B53 CPU is a special piece of

+ * is to prefetch instruction and/or data with a line size of either 64 bytes
+ * or 256 bytes. The rationale is that the data-bus of the CPU interface is
+ * optimized for 256-byte transactions, and enabling the read-ahead cache
+ * provides a significant performance boost (typically twice the performance
+ * for a memcpy benchmark application).
+ *
+ * The read-ahead cache is transparent for Virtual Address cache maintenance
+ * operations: IC IVAU, DC IVAC, DC CVAC, DC CVAU and DC CIVAC. So no special
+ * handling is needed for the DMA API above and beyond what is included in the
+ * arm64 implementation.
+ *
+ * In addition, since the Point of Unification is typically between L1 and L2
+ * for the Brahma-B53 processor no special read-ahead cache handling is needed
+ * for the IC IALLU and IC IALLUIS cache maintenance operations.
+ *
+ * However, it is not possible to specify the cache level (L3) for the cache
+ * maintenance instructions operating by set/way to operate on the read-ahead
+ * cache. The read-ahead cache will maintain coherency when inner cache lines
+ * are cleaned by set/way, but if it is necessary to invalidate inner cache
+ * lines by set/way to maintain coherency with system masters operating on
+ * shared memory that does not have hardware support for coherency, then it
+ * will also be necessary to explicitly invalidate the read-ahead cache.

+ * Ext4 Fast Commits
+ * -----------------
+ *
+ * Ext4 fast commits implement fine grained journalling for Ext4.
+ *
+ * Fast commits are organized as a log of tag-length-value (TLV) structs. (See
+ * struct ext4_fc_tl). Each TLV contains some delta that is replayed TLV by
+ * TLV during the recovery phase. For the scenarios for which we currently
+ * don't have replay code, fast commit falls back to full commits.
+ * Fast commits record delta in one of the following three categories.
+ *
+ * (A) Directory entry updates:
+ *
+ * - EXT4_FC_TAG_UNLINK - records directory entry unlink
+ * - EXT4_FC_TAG_LINK - records directory entry link
+ * - EXT4_FC_TAG_CREAT - records inode and directory entry creation
+ *
+ * (B) File specific data range updates:
+ *
+ * - EXT4_FC_TAG_ADD_RANGE - records addition of new blocks to an inode
+ * - EXT4_FC_TAG_DEL_RANGE - records deletion of blocks from an inode
+ *
+ * (C) Inode metadata (mtime / ctime etc):
+ *
+ * - EXT4_FC_TAG_INODE - record the inode that should be replayed
+ * during recovery. Note that iblocks field is
+ * not replayed and instead derived during
+ * replay.
+ * Commit Operation
+ * ----------------
+ * With fast commits, we maintain all the directory entry operations in the
+ * order in which they are issued in an in-memory queue. This queue is flushed
+ * to disk during the commit operation. We also maintain a list of inodes
+ * that need to be committed during a fast commit in another in memory queue of
+ * inodes. During the commit operation, we commit in the following order:
+ *
+ * [1] Lock inodes for any further data updates by setting COMMITTING state
+ * [2] Submit data buffers of all the inodes
+ * [3] Wait for [2] to complete
+ * [4] Commit all the directory entry updates in the fast commit space
+ * [5] Commit all the changed inode structures
+ * [6] Write tail tag (this tag ensures the atomicity, please read the following
+ * section for more details).
+ * [7] Wait for [4], [5] and [6] to complete.
+ *
+ * All the inode updates must call ext4_fc_start_update() before starting an
+ * update. If such an ongoing update is present, fast commit waits for it to
+ * complete. The completion of such an update is marked by
+ * ext4_fc_stop_update().
+ *
+ * Fast Commit Ineligibility
+ * -------------------------
+ * Not all operations are supported by fast commits today (e.g extended
+ * attributes). Fast commit ineligiblity is marked by calling one of the
+ * two following functions:
+ *
+ * - ext4_fc_mark_ineligible(): This makes next fast commit operation to fall
+ * back to full commit. This is useful in case of transient errors.
+ *
+ * - ext4_fc_start_ineligible() and ext4_fc_stop_ineligible() - This makes all
+ * the fast commits happening between ext4_fc_start_ineligible() and
+ * ext4_fc_stop_ineligible() and one fast commit after the call to
+ * ext4_fc_stop_ineligible() to fall back to full commits. It is important to
+ * make one more fast commit to fall back to full commit after stop call so
+ * that it guaranteed that the fast commit ineligible operation contained
+ * within ext4_fc_start_ineligible() and ext4_fc_stop_ineligible() is
+ * followed by at least 1 full commit.
+ *
+ * Atomicity of commits
+ * --------------------
+ * In order to gaurantee atomicity during the commit operation, fast commit
+ * uses "EXT4_FC_TAG_TAIL" tag that marks a fast commit as complete. Tail
+ * tag contains CRC of the contents and TID of the transaction after which
+ * this fast commit should be applied. Recovery code replays fast commit
+ * logs only if there's at least 1 valid tail present. For every fast commit
+ * operation, there is 1 tail. This means, we may end up with multiple tails
+ * in the fast commit space. Here's an example:
+ *
+ * - Create a new file A and remove existing file B
+ * - fsync()
+ * - Append contents to file A
+ * - Truncate file A
+ * - fsync()
+ *
+ * The fast commit space at the end of above operations would look like this:
+ * [HEAD] [CREAT A] [UNLINK B] [TAIL] [ADD_RANGE A] [DEL_RANGE A] [TAIL]
+ * |<--- Fast Commit 1 --->|<--- Fast Commit 2 ---->|
+ *
+ * Replay code should thus check for all the valid tails in the FC area.
+ *
+ * TODOs
+ * -----
+ * 1) Make fast commit atomic updates more fine grained. Today, a fast commit
+ * eligible update must be protected within ext4_fc_start_update() and
+ * ext4_fc_stop_update(). These routines are called at much higher
+ * routines. This can be made more fine grained by combining with
+ * ext4_journal_start().
+ *
+ * 2) Same above for ext4_fc_start_ineligible() and ext4_fc_stop_ineligible()
+ *
+ * 3) Handle more ineligible cases.

-# namespace.pl. Mon Aug 30 2004
-#
-# Perform a name space analysis on the linux kernel.
-#
-# Copyright Keith Owens <kaos@ocs.com.au>. GPL.
-#
-# Invoke by changing directory to the top of the kernel object
-# tree then namespace.pl, no parameters.
-#
-# Tuned for 2.1.x kernels with the new module handling, it will
-# work with 2.0 kernels as well.
-#
-# Last change 2.6.9-rc1, adding support for separate source and object
-# trees.
-#
-# The source must be compiled/assembled first, the object files
-# are the primary input to this script. Incomplete or missing
-# objects will result in a flawed analysis. Compile both vmlinux
-# and modules.
-#
-# Even with complete objects, treat the result of the analysis
-# with caution. Some external references are only used by
-# certain architectures, others with certain combinations of
-# configuration parameters. Ideally the source should include
-# something like
-#
-# #ifndef CONFIG_...
-# static
-# #endif
-# symbol_definition;
-#
-# so the symbols are defined as static unless a particular
-# CONFIG_... requires it to be external.
-#
-# A symbol that is suffixed with '(export only)' has these properties
-#
-# * It is global.
-# * It is marked EXPORT_SYMBOL or EXPORT_SYMBOL_GPL, either in the same
-# source file or a different source file.
-# * Given the current .config, nothing uses the symbol.
-#
-# The symbol is a candidate for conversion to static, plus removal of the
-# export. But be careful that a different .config might use the symbol.
-#
-#
-# Name space analysis and cleanup is an iterative process. You cannot
-# expect to find all the problems in a single pass.
-#
-# * Identify possibly unnecessary global declarations, verify that they
-# really are unnecessary and change them to static.
-# * Compile and fix up gcc warnings about static, removing dead symbols
-# as necessary.
-# * make clean and rebuild with different configs (especially
-# CONFIG_MODULES=n) to see which symbols are being defined when the
-# config does not require them. These symbols bloat the kernel object
-# for no good reason, which is frustrating for embedded systems.
-# * Wrap config sensitive symbols in #ifdef CONFIG_foo, as long as the
-# code does not get too ugly.
-# * Repeat the name space analysis until you can live with with the
-# result.
