+Linux カーネルパッチ投稿者向けチェックリスト
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+本書では、パッチをより素早く取り込んでもらいたい開発者が実践すべき基本的な事柄
+をいくつか紹介します。ここにある全ての事柄は、Documentation/SubmittingPatches
+などのLinuxカーネルパッチ投稿に際しての心得を補足するものです。
+
+ 1: 妥当なCONFIGオプションや変更されたCONFIGオプション、つまり =y, =m, =n
+    全てで正しくビルドできることを確認してください。その際、gcc及びリンカが
+    warningやerrorを出していないことも確認してください。
+
+ 2: allnoconfig, allmodconfig オプションを用いて正しくビルドできることを
+    確認してください。
+
+ 3: 手許のクロスコンパイルツールやOSDLのPLMのようなものを用いて、複数の
+    アーキテクチャにおいても正しくビルドできることを確認してください。
+
+ 4: 64bit長の'unsigned long'を使用しているppc64は、クロスコンパイルでの
+    チェックに適当なアーキテクチャです。
+
+ 5: カーネルコーディングスタイルに準拠しているかどうか確認してください(!)
+
+ 6: CONFIGオプションの追加・変更をした場合には、CONFIGメニューが壊れていない
+    ことを確認してください。
+
+ 7: 新しくKconfigのオプションを追加する際には、必ずそのhelpも記述してください。
+
+ 8: 適切なKconfigの依存関係を考えながら慎重にチェックしてください。
+    ただし、この作業はマシンを使ったテストできちんと行うのがとても困難です。
+    うまくやるには、自分の頭で考えることです。
+
+ 9: sparseを利用してちゃんとしたコードチェックをしてください。
+
+10: 'make checkstack' と 'make namespacecheck' を利用し、問題が発見されたら
+    修正してください。'make checkstack' は明示的に問題を示しませんが、どれか
+    １つの関数が512バイトより大きいスタックを使っていれば、修正すべき候補と
+    なります。
+
+11: グローバルなkernel API を説明する kernel-doc をソースの中に含めてください。
+    ( staticな関数においては必須ではありませんが、含めてもらっても結構です )
+    そして、'make htmldocs' もしくは 'make mandocs' を利用して追記した
+    ドキュメントのチェックを行い、問題が見つかった場合には修正を行ってください。
+
+12: CONFIG_PREEMPT, CONFIG_DEBUG_PREEMPT, CONFIG_DEBUG_SLAB,
+    CONFIG_DEBUG_PAGEALLOC, CONFIG_DEBUG_MUTEXES, CONFIG_DEBUG_SPINLOCK,
+    CONFIG_DEBUG_SPINLOCK_SLEEP これら全てを同時に有効にして動作確認を
+    行ってください。
+
+13: CONFIG_SMP, CONFIG_PREEMPT を有効にした場合と無効にした場合の両方で
+    ビルドした上、動作確認を行ってください。
+
+14: もしパッチがディスクのI/O性能などに影響を与えるようであれば、
+    'CONFIG_LBD'オプションを有効にした場合と無効にした場合の両方で
+    テストを実施してみてください。
+
+15: lockdepの機能を全て有効にした上で、全てのコードパスを評価してください。
+
+16: /proc に新しいエントリを追加した場合には、Documentation/ 配下に
+    必ずドキュメントを追加してください。
+
+17: 新しいブートパラメータを追加した場合には、
+    必ずDocumentation/kernel-parameters.txt に説明を追加してください。
+
+18: 新しくmoduleにパラメータを追加した場合には、MODULE_PARM_DESC()を
+    利用して必ずその説明を記述してください。
+
+19: 新しいuserspaceインタフェースを作成した場合には、Documentation/ABI/ に
+    Documentation/ABI/README を参考にして必ずドキュメントを追加してください。
+
+20: 'make headers_check'を実行して全く問題がないことを確認してください。
+
+21: 少なくともslabアロケーションとpageアロケーションに失敗した場合の
+    挙動について、fault-injectionを利用して確認してください。
+    Documentation/fault-injection/ を参照してください。
+
+    追加したコードがかなりの量であったならば、サブシステム特有の
+    fault-injectionを追加したほうが良いかもしれません。
+
+22: 新たに追加したコードは、`gcc -W'でコンパイルしてください。
+    このオプションは大量の不要なメッセージを出力しますが、
+    "warning: comparison between signed and unsigned" のようなメッセージは、
+    バグを見つけるのに役に立ちます。
+
+23: 投稿したパッチが -mm パッチセットにマージされた後、全ての既存のパッチや
+    VM, VFS およびその他のサブシステムに関する様々な変更と、現時点でも共存
+    できることを確認するテストを行ってください。

-What is it? What can I do with it?
-==================================
-The auerswald USB kernel driver connects your linux 2.4.x
-system to the auerswald usb-enabled devices.
-
-There are two types of auerswald usb devices:
-a) small PBX systems (ISDN)
-b) COMfort system telephones (ISDN)
-
-The driver installation creates the devices
-/dev/usb/auer0..15. These devices carry a vendor-
-specific protocol. You may run all auerswald java
-software on it. The java software needs a native
-library "libAuerUsbJNINative.so" installed on
-your system. This library is available from
-auerswald and shipped as part of the java software.
-
-You may create the devices with:
-	mknod -m 666 /dev/usb/auer0 c 180 112
-	...
-	mknod -m 666 /dev/usb/auer15 c 180 127
-
-Future plans

 Alternatively, if the critical section might call some of the

+	  Reads on the Blackfin are speculative. In Blackfin terms, this means
+	  they can be interrupted at any time (even after they have been issued
+	  on to the external bus), and re-issued after the interrupt occurs.
+	  For memory - this is not a big deal, since memory does not change if
+	  it sees a read.
+
+	  If a FIFO is sitting on the end of the read, it will see two reads,
+	  when the core only sees one since the FIFO receives both the read
+	  which is cancelled (and not delivered to the core) and the one which
+	  is re-issued (which is delivered to the core).
+
+	  To solve this, interrupts are turned off before reads occur to
+	  I/O space. This option controls which the overhead/latency of
+	  controlling interrupts during this time
+	   "n" turns interrupts off every read
+		(higher overhead, but lower interrupt latency)
+	   "y" turns interrupts off every loop
+		(low overhead, but longer interrupt latency)
+
+	  default behavior is to leave this set to on (type "Y"). If you are experiencing
+	  interrupt latency issues, it is safe and OK to turn this off.

+ * example that utilizes the USB_QUIRK_RESET_RESUME quirk in order to
+ * recieve a reset_resume request rather than the normal resume.

+ * plus start_traffic, it seems easier to always do the switch when

+ * txdma queue with multiple requests (urb or usb_request) looks
+ * like it would work ... but fault handling would need much testing.
+ *
+ * The main issue with TX mode RNDIS relates to transfer lengths that
+ * are an exact multiple of the packet length.  It appears that there's
+ * a hiccup in that case (maybe the DMA completes before the ZLP gets
+ * written?) boiling down to not being able to rely on CPPI writing any
+ * terminating zero length packet before the next transfer is written.
+ * So that's punted to PIO; better yet, gadget drivers can avoid it.
+ *
+ * Plus, there's allegedly an undocumented constraint that rndis transfer
+ * length be a multiple of 64 bytes ... but the chip doesn't act that
+ * way, and we really don't _want_ that behavior anyway.
+ *
+ * On TX, "transparent" mode works ... although experiments have shown
+ * problems trying to use the SOP/EOP bits in different USB packets.
+ *
+ * REVISIT try to handle terminating zero length packets using CPPI
+ * instead of doing it by PIO after an IRQ.  (Meanwhile, make Ethernet

+ * CPPI RX Woes:
+ * =============
+ * Consider a 1KB bulk RX buffer in two scenarios:  (a) it's fed two 300 byte
+ * packets back-to-back, and (b) it's fed two 512 byte packets back-to-back.
+ * (Full speed transfers have similar scenarios.)
+ *
+ * The correct behavior for Linux is that (a) fills the buffer with 300 bytes,
+ * and the next packet goes into a buffer that's queued later; while (b) fills
+ * the buffer with 1024 bytes.  How to do that with CPPI?
+ *
+ * - RX queues in "rndis" mode -- one single BD -- handle (a) correctly, but
+ *   (b) loses **BADLY** because nothing (!) happens when that second packet
+ *   fills the buffer, much less when a third one arrives.  (Which makes this
+ *   not a "true" RNDIS mode.  In the RNDIS protocol short-packet termination
+ *   is optional, and it's fine if peripherals -- not hosts! -- pad messages
+ *   out to end-of-buffer.  Standard PCI host controller DMA descriptors
+ *   implement that mode by default ... which is no accident.)
+ *
+ * - RX queues in "transparent" mode -- two BDs with 512 bytes each -- have
+ *   converse problems:  (b) is handled right, but (a) loses badly.  CPPI RX
+ *   ignores SOP/EOP markings and processes both of those BDs; so both packets
+ *   are loaded into the buffer (with a 212 byte gap between them), and the next
+ *   buffer queued will NOT get its 300 bytes of data. (It seems like SOP/EOP
+ *   are intended as outputs for RX queues, not inputs...)
+ *
+ * - A variant of "transparent" mode -- one BD at a time -- is the only way to
+ *   reliably make both cases work, with software handling both cases correctly
+ *   and at the significant penalty of needing an IRQ per packet.  (The lack of
+ *   I/O overlap can be slightly ameliorated by enabling double buffering.)
+ *
+ * So how to get rid of IRQ-per-packet?  The transparent multi-BD case could
+ * be used in special cases like mass storage, which sets URB_SHORT_NOT_OK
+ * (or maybe its peripheral side counterpart) to flag (a) scenarios as errors
+ * with guaranteed driver level fault recovery and scrubbing out what's left
+ * of that garbaged datastream.
+ *
+ * But there seems to be no way to identify the cases where CPPI RNDIS mode
+ * is appropriate -- which do NOT include RNDIS host drivers, but do include
+ * the CDC Ethernet driver! -- and the documentation is incomplete/wrong.
+ * So we can't _ever_ use RX RNDIS mode ... except by using a heuristic
+ * that applies best on the peripheral side (and which could fail rudely).
+ *
+ * Leaving only "transparent" mode; we avoid multi-bd modes in almost all
+ * cases other than mass storage class.  Otherwise we're correct but slow,
+ * since CPPI penalizes our need for a "true RNDIS" default mode.
+ */

+/* Heuristic, intended to kick in for ethernet/rndis peripheral ONLY

+ *	a largely unknowable variety of host side protocol variants
+ *  (b)	and short reads are NOT errors ... since full reads would

+ *  (c)	and read length is
+ *	- less than 64KB (max per cppi descriptor)

+ * Inventra (Multipoint) Dual-Role Controller Driver for Linux.
+ *
+ * This consists of a Host Controller Driver (HCD) and a peripheral
+ * controller driver implementing the "Gadget" API; OTG support is
+ * in the works.  These are normal Linux-USB controller drivers which
+ * use IRQs and have no dedicated thread.
+ *
+ * This version of the driver has only been used with products from
+ * Texas Instruments.  Those products integrate the Inventra logic
+ * with other DMA, IRQ, and bus modules, as well as other logic that
+ * needs to be reflected in this driver.
+ *
+ *
+ * NOTE:  the original Mentor code here was pretty much a collection
+ * of mechanisms that don't seem to have been fully integrated/working
+ * for *any* Linux kernel version.  This version aims at Linux 2.6.now,
+ * Key open issues include:
+ *
+ *  - Lack of host-side transaction scheduling, for all transfer types.
+ *    The hardware doesn't do it; instead, software must.
+ *
+ *    This is not an issue for OTG devices that don't support external
+ *    hubs, but for more "normal" USB hosts it's a user issue that the
+ *    "multipoint" support doesn't scale in the expected ways.  That
+ *    includes DaVinci EVM in a common non-OTG mode.
+ *
+ *      * Control and bulk use dedicated endpoints, and there's as
+ *        yet no mechanism to either (a) reclaim the hardware when
+ *        peripherals are NAKing, which gets complicated with bulk
+ *        endpoints, or (b) use more than a single bulk endpoint in
+ *        each direction.
+ *
+ *        RESULT:  one device may be perceived as blocking another one.
+ *
+ *      * Interrupt and isochronous will dynamically allocate endpoint
+ *        hardware, but (a) there's no record keeping for bandwidth;
+ *        (b) in the common case that few endpoints are available, there
+ *        is no mechanism to reuse endpoints to talk to multiple devices.
+ *
+ *        RESULT:  At one extreme, bandwidth can be overcommitted in
+ *        some hardware configurations, no faults will be reported.
+ *        At the other extreme, the bandwidth capabilities which do
+ *        exist tend to be severely undercommitted.  You can't yet hook
+ *        up both a keyboard and a mouse to an external USB hub.
+ */
+
+/*
+ * This gets many kinds of configuration information:
+ *	- Kconfig for everything user-configurable
+ *	- <asm/arch/hdrc_cnf.h> for SOC or family details
+ *	- platform_device for addressing, irq, and platform_data
+ *	- platform_data is mostly for board-specific informarion
+ *
+ * Most of the conditional compilation will (someday) vanish.

+ * - Mass storage behaved ok when last tested.  Network traffic patterns
+ *   (with lots of short transfers etc) need retesting; they turn up the
+ *   worst cases of the DMA, since short packets are typical but are not
+ *   required.
+ *
+ * - TX/IN
+ *     + both pio and dma behave in with network and g_zero tests
+ *     + no cppi throughput issues other than no-hw-queueing
+ *     + failed with FLAT_REG (DaVinci)
+ *     + seems to behave with double buffering, PIO -and- CPPI
+ *     + with gadgetfs + AIO, requests got lost?
+ *
+ * - RX/OUT
+ *     + both pio and dma behave in with network and g_zero tests
+ *     + dma is slow in typical case (short_not_ok is clear)
+ *     + double buffering ok with PIO
+ *     + double buffering *FAILS* with CPPI, wrong data bytes sometimes
+ *     + request lossage observed with gadgetfs
+ *
+ * - ISO not tested ... might work, but only weakly isochronous
+ *
+ * - Gadget driver disabling of softconnect during bind() is ignored; so
+ *   drivers can't hold off host requests until userspace is ready.
+ *   (Workaround:  they can turn it off later.)

+/* MUSB HOST status 22-mar-2006
+ *
+ * - There's still lots of partial code duplication for fault paths, so
+ *   they aren't handled as consistently as they need to be.
+ *
+ * - PIO mostly behaved when last tested.
+ *     + including ep0, with all usbtest cases 9, 10
+ *     + usbtest 14 (ep0out) doesn't seem to run at all
+ *     + double buffered OUT/TX endpoints saw stalls(!) with certain usbtest
+ *       configurations, but otherwise double buffering passes basic tests.
+ *     + for 2.6.N, for N > ~10, needs API changes for hcd framework.
+ *
+ * - DMA (CPPI) ... partially behaves, not currently recommended
+ *     + about 1/15 the speed of typical EHCI implementations (PCI)
+ *     + RX, all too often reqpkt seems to misbehave after tx
+ *     + TX, no known issues (other than evident silicon issue)
+ *
+ * - DMA (Mentor/OMAP) ...has at least toggle update problems
+ *
+ * - Still no traffic scheduling code to make NAKing for bulk or control
+ *   transfers unable to starve other requests; or to make efficient use
+ *   of hardware with periodic transfers.  (Note that network drivers
+ *   commonly post bulk reads that stay pending for a long time; these
+ *   would make very visible trouble.)
+ *
+ * - Not tested with HNP, but some SRP paths seem to behave.
+ *
+ * NOTE 24-August-2006:
+ *
+ * - Bulk traffic finally uses both sides of hardware ep1, freeing up an
+ *   extra endpoint for periodic use enabling hub + keybd + mouse.  That
+ *   mostly works, except that with "usbnet" it's easy to trigger cases
+ *   with "ping" where RX loses.  (a) ping to davinci, even "ping -f",
+ *   fine; but (b) ping _from_ davinci, even "ping -c 1", ICMP RX loses
+ *   although ARP RX wins.  (That test was done with a full speed link.)
+ */
+
+
+/*
+ * NOTE on endpoint usage:
+ *
+ * CONTROL transfers all go through ep0.  BULK ones go through dedicated IN
+ * and OUT endpoints ... hardware is dedicated for those "async" queue(s).
+ *
+ * (Yes, bulk _could_ use more of the endpoints than that, and would even
+ * benefit from it ... one remote device may easily be NAKing while others
+ * need to perform transfers in that same direction.  The same thing could
+ * be done in software though, assuming dma cooperates.)
+ *
+ * INTERUPPT and ISOCHRONOUS transfers are scheduled to the other endpoints.
+ * So far that scheduling is both dumb and optimistic:  the endpoint will be
+ * "claimed" until its software queue is no longer refilled.  No multiplexing
+ * of transfers between endpoints, or anything clever.

+ *
+ * When regular file inodes are unlinked or a directory inode is removed, the

+ * 'ubifs_jnl_delete_inode()', the deletion inode is not in the journal
+ * anymore, and in fact it might not be on the flash anymore, because it might
+ * have been garbage-collected already. And for optimization reasons UBIFS does
+ * not read the orphan area if it has been unmounted cleanly, so it would have
+ * no indication in the journal that there is a deleted inode which has to be
+ * removed from TNC.
+ *
+ * However, if there was no commit between 'ubifs_jnl_update()' and
+ * 'ubifs_jnl_delete_inode()', then there is no need to write the deletion
+ * inode to the media for the second time. And this is quite a typical case.
