Date: July 2011
KernelVersion: 3.1
Contact: Kirill Smelkov <kirr@mns.spb.ru>
Description: Maximum time allowed for periodic transfers per microframe (μs)
[ USB 2.0 sets maximum allowed time for periodic transfers per
microframe to be 80%, that is 100 microseconds out of 125
microseconds (full microframe).
However there are cases, when 80% max isochronous bandwidth is
too limiting. For example two video streams could require 110
microseconds of isochronous bandwidth per microframe to work
together. ]
Through this setting it is possible to raise the limit so that
the host controller would allow allocating more than 100
microseconds of periodic bandwidth per microframe.
Beware, non-standard modes are usually not thoroughly tested by
hardware designers, and the hardware can malfunction when this
setting differ from default 100.

What: noswapaccount kernel command line parameter
When: 2.6.40
Why: The original implementation of memsw feature enabled by
CONFIG_CGROUP_MEM_RES_CTLR_SWAP could be disabled by the noswapaccount
kernel parameter (introduced in 2.6.29-rc1). Later on, this decision
turned out to be not ideal because we cannot have the feature compiled
in and disabled by default and let only interested to enable it
(e.g. general distribution kernels might need it). Therefore we have
added swapaccount[=0|1] parameter (introduced in 2.6.37) which provides
the both possibilities. If we remove noswapaccount we will have
less command line parameters with the same functionality and we
can also cleanup the parameter handling a bit ().

Supported chips:

Prefix: 'sch5636'
Addresses scanned: none, address read from Super I/O config space
Author: Hans de Goede <hdegoede@redhat.com>
Description
-----------
SMSC SCH5636 Super I/O chips include an embedded microcontroller for
hardware monitoring solutions, allowing motherboard manufacturers to create
their own custom hwmon solution based upon the SCH5636.
Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636 based
hwmon solution. The sch5636 driver runs a sanity check on loading to ensure
it is dealing with a Fujitsu Theseus and not with another custom SCH5636 based
hwmon solution.
The Fujitsu Theseus can monitor up to 5 voltages, 8 fans and 16
temperatures. Note that the driver detects how many fan headers /
temperature sensors are actually implemented on the motherboard, so you will
likely see fewer temperature and fan inputs.
An application note describing the Theseus' registers, as well as an
application note describing the protocol for communicating with the
microcontroller is available upon request. Please mail me if you want a copy.

13) いつ Acked-by: を使うのか
あなたがサブシステムまたはブランチのメンテナであれば、受け取ったパッチを自身の
ツリーにマージするために、わずかに変更が必要となる場合があります。なぜなら
あなたのツリーの中のコードと投稿者のツリーの中のコードは同一ではないためです。
もし、あなたが厳密に上記ルール(c)にこだわるのであれば、投稿者に再度差分を
とるよう依頼すべきです。しかし、これは時間とエネルギーを非生産的に浪費する
ことになります。ルール(b)はあなたにコードを修正する権利を与えてくれます。
しかし、投稿者のコードを修正し、その修正によるバグを投稿者に押し付けてしまう
ことはとても失礼なことです。この問題を解決するために、末尾の投稿者の
Signed-off-by とあなたがその末尾に追加する Signed-off-by の間に、修正を
加えたことを示す1行を追加することが推奨されています。
(その1行の書き方に)決まりはありませんが、大括弧の中に電子メールアドレスや氏名
と修正内容を記載するやり方は目につきやすく、最終段階での変更の責任があなたに
あることを明確にするのに十分な方法のようです。例えば、
Signed-off-by: Random J Developer <random@developer.example.org>
[lucky@maintainer.example.org: struct foo moved from foo.c to foo.h]
Signed-off-by: Lucky K Maintainer <lucky@maintainer.example.org>

shm_rmid_forced:
Linux lets you set resource limits, including how much memory one
process can consume, via setrlimit(2). Unfortunately, shared memory
segments are allowed to exist without association with any process, and
thus might not be counted against any resource limits. If enabled,
shared memory segments are automatically destroyed when their attach
count becomes zero after a detach or a process termination. It will
also destroy segments that were created, but never attached to, on exit
from the process. The only use left for IPC_RMID is to immediately
destroy an unattached segment. Of course, this breaks the way things are
defined, so some applications might stop working. Note that this
feature will do you no good unless you also configure your resource
limits (in particular, RLIMIT_AS and RLIMIT_NPROC). Most systems don't
need this.
Note that if you change this from 0 to 1, already created segments
without users and with a dead originative process will be destroyed.

Linux内核补丁是通过邮件被提交的，最好把补丁作为邮件体的内嵌文本。有些维护者
接收附件，但是附件的内容格式应该是"text/plain"。然而，附件一般是不赞成的，
因为这会使补丁的引用部分在评论过程中变的很困难。
??ㄦ?ュ?????Linux?????歌ˉ涓???????浠跺?㈡?风????ㄥ?????琛ヤ????跺??璇ュ??浜?????????????濮???舵?????渚?濡?锛?
浠?浠?涓???芥?瑰?????????????ゅ?惰〃绗???????绌烘?硷???????虫????ㄦ??涓?琛????寮?澶存?????缁?灏俱??
用来发送Linux内核补丁的邮件客户端在发送补丁时应该处于文本的原始状态。例如，
他们不能改变或者删除制表符或者空格，甚至是在每一行的开头或者结尾。
涓?瑕????杩?"format=flowed"妯″????????琛ヤ?????杩???蜂??寮?璧蜂?????棰????浠ュ?????瀹崇?????琛????
不要通过"format=flowed"模式发送补丁。这样会引起不可预期以及有害的断行。
涓?瑕?璁╀????????浠跺?㈡?风??杩?琛??????ㄦ?㈣?????杩???蜂??浼???村??浣????琛ヤ?????
不要让你的邮件客户端进行自动换行。这样也会破坏你的补丁。
???浠跺?㈡?风??涓???芥?瑰???????????瀛?绗????缂??????瑰?????瑕??????????琛ヤ???????芥??ASCII??????UTF-8缂??????瑰??锛?
濡????浣?浣跨??UTF-8缂??????瑰???????????浠讹????ｄ??浣?灏?浼???垮??涓?浜??????藉????????瀛?绗???????棰????
邮件客户端不能改变文本的字符集编码方式。要发送的补丁只能是ASCII或者UTF-8编码方式，
如果你使用UTF-8编码方式发送邮件，那么你将会避免一些可能发生的字符集问题。
???浠跺?㈡?风??搴?璇ュ舰???骞朵??淇???? References: ?????? In-Reply-To: ???棰?锛???ｄ??
???浠惰??棰?灏变??浼?涓???????
邮件客户端应该形成并且保持 References: 或者 In-Reply-To: 标题，那么
邮件话题就不会中断。
澶???剁??甯?(?????????璐寸??甯?)???甯镐????界?ㄤ??琛ヤ??锛????涓哄?惰〃绗?浼?杞????涓虹┖??笺??浣跨??xclipboard, xclip
??????xcutsel涔?璁稿??浠ワ??浣???????濂芥??璇?涓?涓?????????垮??浣跨?ㄥ????剁??甯????
复制粘帖(或者剪贴粘帖)通常不能用于补丁，因为制表符会转换为空格。使用xclipboard, xclip
或者xcutsel也许可以，但是最好测试一下或者避免使用复制粘帖。
涓?瑕???ㄤ娇???PGP/GPG缃插????????浠朵腑??????琛ヤ?????杩???蜂??浣垮??寰?澶???????涓???借?诲??????????ㄤ??浣????琛ヤ?????
锛?杩?涓????棰?搴?璇ユ?????浠ヤ慨澶????锛?
不要在使用PGP/GPG署名的邮件中包含补丁。这样会使得很多脚本不能读取和适用于你的补丁。
（这个问题应该是可以修复的）
??ㄧ???????搁??浠跺??琛ㄥ?????琛ヤ??涔????锛?缁????宸卞?????涓?涓?琛ヤ?????涓?涓???????涓绘??锛?淇?瀛???ユ?跺?扮??
???浠讹??灏?琛ヤ?????'patch'??戒护???涓?锛?濡??????????浜?锛????缁??????搁??浠跺??琛ㄥ????????
在给内核邮件列表发送补丁之前，给自己发送一个补丁是个不错的主意，保存接收到的
邮件，将补丁用'patch'命令打上，如果成功了，再给内核邮件列表发送。

?????????杞?浠跺?????缃???荤?????
这里给出一些详细的MUA配置提示，可以用于给Linux内核发送补丁。这些并不意味是
所有的软件包配置总结。
璇存??锛?
TUI = 浠ユ?????涓哄?虹???????ㄦ?锋?ュ??
GUI = ??惧舰?????㈢?ㄦ?锋?ュ??
说明：
TUI = 以文本为基础的用户接口
GUI = 图形界面用户接口
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Alpine (TUI)
???缃????椤癸??
???"Sending Preferences"??ㄥ??锛?
配置选项：
在"Sending Preferences"部分：
- "Do Not Send Flowed Text"蹇?椤诲?????
- "Strip Whitespace Before Sending"蹇?椤诲?抽??
- "Do Not Send Flowed Text"必须开启
- "Strip Whitespace Before Sending"必须关闭
褰???????浠舵?讹????????搴?璇ユ?惧?ㄨˉ涓?浼???虹?扮????版?癸????跺?????涓?CTRL-R缁???????锛?浣挎??瀹????
琛ヤ?????浠跺????ュ?伴??浠朵腑???
当写邮件时，光标应该放在补丁会出现的地方，然后按下CTRL-R组合键，使指定的
补丁文件嵌入到邮件中。
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Evolution (GUI)
涓?浜?寮????????????????浣跨?ㄥ????????琛ヤ??
一些开发者成功的使用它发送补丁
褰??????╅??浠堕??椤癸??Preformat
浠?Format->Heading->Preformatted (Ctrl-7)??????宸ュ?锋??
当选择邮件选项：Preformat
从Format->Heading->Preformatted (Ctrl-7)或者工具栏
??跺??浣跨??锛?
Insert->Text File... (Alt-n x)?????ヨˉ涓????浠躲??
然后使用：
Insert->Text File... (Alt-n x)插入补丁文件。
浣?杩????浠?"diff -Nru old.c new.c | xclip"锛???????Preformat锛???跺??浣跨?ㄤ腑??撮??杩?琛?绮?甯????
你还可以"diff -Nru old.c new.c | xclip"，选择Preformat，然后使用中间键进行粘帖。
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Kmail (GUI)
涓?浜?寮????????????????浣跨?ㄥ????????琛ヤ?????
一些开发者成功的使用它发送补丁。
榛?璁よ?剧疆涓?涓?HTML??煎??????????????锛?涓?瑕??????ㄥ?????
默认设置不为HTML格式是合适的；不要启用它。
褰?涔????涓?灏????浠剁????跺??锛???ㄩ??椤逛?????涓?瑕??????╄????ㄦ?㈣????????涓????缂虹?瑰氨???浣???ㄩ??浠朵腑杈???ョ??浠讳????????

?????╄????ㄦ?㈣??锛?浣????杩?涓?浼?澶卞?诲凡???????????ㄦ?㈣?????
当书写一封邮件的时候，在选项下面不要选择自动换行。唯一的缺点就是你在邮件中输入的任何文本
都不会被自动换行，因此你必须在发送补丁之前手动换行。最简单的方法就是启用自动换行来书写邮件，
然后把它保存为草稿。一旦你在草稿中再次打开它，它已经全部自动换行了，那么你的邮件虽然没有
选择自动换行，但是还不会失去已有的自动换行。
??ㄩ??浠剁??搴????锛??????ヨˉ涓?涔????锛???句??甯哥?ㄧ??琛ヤ??瀹????绗?锛?涓?涓?杩?瀛????(---)???
在邮件的底部，插入补丁之前，放上常用的补丁定界符：三个连字号(---)。
??跺?????"Message"????????＄??锛??????╂????ユ??浠讹????ョ????????浣????琛ヤ?????浠躲??杩????涓?涓?棰?澶???????椤癸??浣????浠?
???杩?瀹????缃?浣???????浠跺缓绔?宸ュ?锋????????锛?杩????浠ュ甫涓?"insert file"??炬?????
然后在"Message"菜单条目，选择插入文件，接着选取你的补丁文件。还有一个额外的选项，你可以
通过它配置你的邮件建立工具栏菜单，还可以带上"insert file"图标。
浣????浠ュ????ㄥ?伴??杩?GPG???璁伴??浠讹??浣???????宓?琛ヤ?????濂戒??瑕?浣跨??GPG???璁板??浠????浣?涓哄??宓??????????绛惧??琛ヤ??锛?
褰?浠?GPG涓???????7浣?缂??????朵??浣夸??浠?????????村??澶???????
你可以安全地通过GPG标记附件，但是内嵌补丁最好不要使用GPG标记它们。作为内嵌文本的签发补丁，
当从GPG中提取7位编码时会使他们变的更加复杂。
濡????浣????瑕?浠ラ??浠剁??褰㈠????????琛ヤ??锛???ｄ??灏卞?抽????瑰?婚??浠讹????跺?????涓?灞???э??绐????"Suggest automatic
display"锛?杩???峰??宓????浠舵?村?规??璁╄?昏???????般??
如果你非要以附件的形式发送补丁，那么就右键点击附件，然后选中属性，突出"Suggest automatic
display"，这样内嵌附件更容易让读者看到。
褰?浣?瑕?淇?瀛?灏?瑕?????????????宓???????琛ヤ??锛?浣????浠ヤ??娑???????琛ㄧ????奸????╁?????琛ヤ????????浠讹????跺????冲?婚?????
"save as"???浣????浠ヤ娇??ㄤ??涓?娌℃????存?圭????????琛ヤ????????浠讹??濡????瀹????浠ユ?ｇ‘???褰㈠??缁???????褰?浣?姝ｇ????ㄥ??

浣?涓?寰?涓????浠?浠????????????逛负缁?????????翠?????璇汇??
当你要保存将要发送的内嵌文本补丁，你可以从消息列表窗格选择包含补丁的邮件，然后右击选择
"save as"。你可以使用一个没有更改的包含补丁的邮件，如果它是以正确的形式组成。当你正真在它
自己的窗口之下察看，那时没有选项可以保存邮件--已经有一个这样的bug被汇报到了kmail的bugzilla
并且希望这将会被处理。邮件是以只针对某个用户可读写的权限被保存的，所以如果你想把邮件复制到其他地方，
你不得不把他们的权限改为组或者整体可读。

不要使用它。

Mutt (TUI)
寰?澶?Linux寮????浜哄??浣跨??mutt瀹㈡?风??锛????浠ヨ?????瀹????瀹?宸ヤ????????甯告??浜????
很多Linux开发人员使用mutt客户端，所以证明它肯定工作的非常漂亮。
Mutt涓????甯?缂?杈????锛????浠ヤ??绠′??浣跨?ㄤ??涔?缂?杈???ㄩ?戒??搴?璇ュ甫????????ㄦ??琛????澶у????扮??杈???ㄩ?藉甫???
涓?涓?"insert file"???椤癸??瀹????浠ラ??杩?涓???瑰?????浠跺??瀹圭????瑰???????ユ??浠躲??
Mutt不自带编辑器，所以不管你使用什么编辑器都不应该带有自动断行。大多数编辑器都带有
一个"insert file"选项，它可以通过不改变文件内容的方式插入文件。
'vim'浣?涓?mutt???缂?杈????锛?
'vim'作为mutt的编辑器：
set editor="vi"
濡????浣跨??xclip锛???插?ヤ互涓???戒护
如果使用xclip，敲入以下命令
:set paste
???涓????涔??????????shift-insert??????浣跨??
按中键之前或者shift-insert或者使用
:r filename
濡??????宠?????琛ヤ??浣?涓哄??宓??????????
(a)ttach宸ヤ?????寰?濂斤??涓?甯????"set paste"???
如果想要把补丁作为内嵌文本。
(a)ttach工作的很好，不带有"set paste"。
???缃????椤癸??
瀹?搴?璇ヤ互榛?璁よ?剧疆???褰㈠??宸ヤ?????
??惰??锛????"send_charset"璁剧疆涓?"us-ascii::utf-8"涔????涓?涓?涓???????涓绘?????
配置选项：
它应该以默认设置的形式工作。
然而，把"send_charset"设置为"us-ascii::utf-8"也是一个不错的主意。
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Pine (TUI)
Pine杩???绘??涓?浜?绌烘?煎????????棰?锛?浣????杩?浜???板?ㄥ??璇ラ?借??淇?澶?浜????
Pine过去有一些空格删减问题，但是这些现在应该都被修复了。
濡???????浠ワ??璇蜂娇???alpine(pine???缁ф?胯??)
如果可以，请使用alpine(pine的继承者)
???缃????椤癸??
- ???杩?????????????瑕?娑???ゆ??绋???????

配置选项：
- 最近的版本需要消除流程文本
- "no-strip-whitespace-before-send"选项也是需要的。
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Sylpheed (GUI)

- 内嵌文本可以很好的工作（或者使用附件）。
- 允许使用外部的编辑器。
- 对于目录较多时非常慢。
- 如果通过non-SSL连接，无法使用TLS SMTP授权。
- 在组成窗口中有一个很有用的ruler bar。
- 给地址本中添加地址就不会正确的了解显示名。
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Thunderbird (GUI)
榛?璁ゆ????典??锛?thunderbird寰?瀹规??????????????锛?浣????杩????涓?浜???规?????浠ュ己??跺?????寰???村ソ???
默认情况下，thunderbird很容易损坏文本，但是还有一些方法可以强制它变得更好。
- ??ㄧ?ㄦ?峰????疯?剧疆???锛?缁???????瀵诲??锛?涓?瑕???????"Compose messages in HTML format"???
- 在用户帐号设置里，组成和寻址，不要选择"Compose messages in HTML format"。
- 缂?杈?浣????Thunderbird???缃?璁剧疆??ヤ娇瀹?涓?瑕????琛?浣跨??锛?user_pref("mailnews.wraplength", 0);
- 编辑你的Thunderbird配置设置来使它不要拆行使用：user_pref("mailnews.wraplength", 0);
- 缂?杈?浣????Thunderbird???缃?璁剧疆锛?浣垮??涓?瑕?浣跨??"format=flowed"??煎??锛?user_pref("mailnews.
- 编辑你的Thunderbird配置设置，使它不要使用"format=flowed"格式：user_pref("mailnews.
send_plaintext_flowed", false);
- 浣????瑕?浣?Thunderbird???涓洪???????煎????瑰??锛?
濡????榛?璁ゆ????典??浣?涔??????????HTML??煎??锛???ｄ?????寰???俱??浠?浠?浠????棰???????涓????妗?涓???????"Preformat"??煎?????

??煎??锛???跺?????棰???????涓????妗?涓???????"Preformat"??煎?????
- 你需要使Thunderbird变为预先格式方式：
如果默认情况下你书写的是HTML格式，那不是很难。仅仅从标题栏的下拉框中选择"Preformat"格式。
如果默认情况下你书写的是文本格式，你不得把它改为HTML格式（仅仅作为一次性的）来书写新的消息，
然后强制使它回到文本格式，否则它就会拆行。要实现它，在写信的图标上使用shift键来使它变为HTML
格式，然后标题栏的下拉框中选择"Preformat"格式。
- ???璁镐娇??ㄥ????ㄧ??缂?杈????锛?

??????View->Toolbars->Customize...??????褰?浣?涔????淇℃???????跺??浠?浠???瑰?诲??灏卞??浠ヤ?????
- 允许使用外部的编辑器：
针对Thunderbird打补丁最简单的方法就是使用一个"external editor"扩展，然后使用你最喜欢的
$EDITOR来读取或者合并补丁到文本中。要实现它，可以下载并且安装这个扩展，然后添加一个使用它的
按键View->Toolbars->Customize...最后当你书写信息的时候仅仅点击它就可以了。
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
TkRat (GUI)
???浠ヤ娇??ㄥ?????浣跨??"Insert file..."??????澶???ㄧ??缂?杈???ㄣ??
可以使用它。使用"Insert file..."或者外部的编辑器。
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Gmail (Web GUI)
涓?瑕?浣跨?ㄥ????????琛ヤ?????
不要使用它发送补丁。
Gmail缃?椤靛?㈡?风???????ㄥ?版????惰〃绗?杞????涓虹┖??笺??
Gmail网页客户端自动地把制表符转换为空格。
??界?跺?惰〃绗?杞????涓虹┖??奸??棰????浠ヨ??澶???ㄧ??杈???ㄨВ??筹???????跺??杩?浼?浣跨?ㄥ??杞???㈣?????姣?琛???????涓?78涓?瀛?绗????
虽然制表符转换为空格问题可以被外部编辑器解决，同时它还会使用回车换行把每行拆分为78个字符。
???涓?涓????棰????Gmail杩?浼????浠讳??涓????ASCII???瀛?绗????淇℃????逛负base64缂???????瀹????涓?瑗垮????????娆ф床浜虹?????瀛????
另一个问题是Gmail还会把任何不是ASCII的字符的信息改为base64编码。它把东西变的像欧洲人的名字。
