These include subsystem maintainers and reviewers who need to decide
whether the patch should be included, distributors and other maintainers
trying to decide whether a patch should be backported to other kernels, bug
hunters wondering whether the patch is responsible for a problem they are
chasing, users who want to know how the kernel has changed, and more. A
good changelog conveys the needed information to all of these people in the
most direct and concise way possible.
To that end, the summary line should describe the effects of and motivation
for the change as well as possible given the one-line constraint. The
detailed description can then amplify on those topics and provide any
needed additional information. If the patch fixes a bug, cite the commit
which introduced the bug if possible. If a problem is associated with
specific log or compiler output, include that output to help others
searching for a solution to the same problem. If the change is meant to
support other changes coming in later patch, say so. If internal APIs are
changed, detail those changes and how other developers should respond. In
general, the more you can put yourself into the shoes of everybody who will

Copyright 2009 Jonathan Corbet <corbet@lwn.net>
Debugfs exists as a simple way for kernel developers to make information
available to user space. Unlike /proc, which is only meant for information
about a process, or sysfs, which has strict one-value-per-file rules,
debugfs has no rules at all. Developers can put any information they want
there. The debugfs filesystem is also intended to not serve as a stable
ABI to user space; in theory, there are no stability constraints placed on
files exported there. The real world is not always so simple, though [1];
even debugfs interfaces are best designed with the idea that they will need
to be maintained forever.
Debugfs is typically mounted with a command like:
mount -t debugfs none /sys/kernel/debug
(Or an equivalent /etc/fstab line).
Note that the debugfs API is exported GPL-only to modules.
Code using debugfs should include <linux/debugfs.h>. Then, the first order
of business will be to create at least one directory to hold a set of
debugfs files:
struct dentry *debugfs_create_dir(const char *name, struct dentry *parent);
This call, if successful, will make a directory called name underneath the
indicated parent directory. If parent is NULL, the directory will be
created in the debugfs root. On success, the return value is a struct
dentry pointer which can be used to create files in the directory (and to
clean it up at the end). A NULL return value indicates that something went
wrong. If ERR_PTR(-ENODEV) is returned, that is an indication that the
kernel has been built without debugfs support and none of the functions
described below will work.
The most general way to create a file within a debugfs directory is with:
struct dentry *debugfs_create_file(const char *name, mode_t mode,
struct dentry *parent, void *data,
const struct file_operations *fops);
Here, name is the name of the file to create, mode describes the access
permissions the file should have, parent indicates the directory which
should hold the file, data will be stored in the i_private field of the
resulting inode structure, and fops is a set of file operations which
implement the file's behavior. At a minimum, the read() and/or write()
operations should be provided; others can be included as needed. Again,
the return value will be a dentry pointer to the created file, NULL for
error, or ERR_PTR(-ENODEV) if debugfs support is missing.
In a number of cases, the creation of a set of file operations is not
actually necessary; the debugfs code provides a number of helper functions
for simple situations. Files containing a single integer value can be
created with any of:
struct dentry *debugfs_create_u8(const char *name, mode_t mode,
struct dentry *parent, u8 *value);
struct dentry *debugfs_create_u16(const char *name, mode_t mode,
struct dentry *parent, u16 *value);
struct dentry *debugfs_create_u32(const char *name, mode_t mode,
struct dentry *parent, u32 *value);
struct dentry *debugfs_create_u64(const char *name, mode_t mode,
struct dentry *parent, u64 *value);
These files support both reading and writing the given value; if a specific
file should not be written to, simply set the mode bits accordingly. The
values in these files are in decimal; if hexadecimal is more appropriate,
the following functions can be used instead:
struct dentry *debugfs_create_x8(const char *name, mode_t mode,
struct dentry *parent, u8 *value);
struct dentry *debugfs_create_x16(const char *name, mode_t mode,
struct dentry *parent, u16 *value);
struct dentry *debugfs_create_x32(const char *name, mode_t mode,
struct dentry *parent, u32 *value);
Note that there is no debugfs_create_x64().
These functions are useful as long as the developer knows the size of the
value to be exported. Some types can have different widths on different
architectures, though, complicating the situation somewhat. There is a
function meant to help out in one special case:
struct dentry *debugfs_create_size_t(const char *name, mode_t mode,
struct dentry *parent,
size_t *value);
As might be expected, this function will create a debugfs file to represent
a variable of type size_t.
Boolean values can be placed in debugfs with:
struct dentry *debugfs_create_bool(const char *name, mode_t mode,
struct dentry *parent, u32 *value);
A read on the resulting file will yield either Y (for non-zero values) or
N, followed by a newline. If written to, it will accept either upper- or
lower-case values, or 1 or 0. Any other input will be silently ignored.
Finally, a block of arbitrary binary data can be exported with:
struct debugfs_blob_wrapper {
void *data;
unsigned long size;
};
struct dentry *debugfs_create_blob(const char *name, mode_t mode,
struct dentry *parent,
struct debugfs_blob_wrapper *blob);
A read of this file will return the data pointed to by the
debugfs_blob_wrapper structure. Some drivers use "blobs" as a simple way
to return several lines of (static) formatted text output. This function
can be used to export binary information, but there does not appear to be
any code which does so in the mainline. Note that all files created with
debugfs_create_blob() are read-only.
There are a couple of other directory-oriented helper functions:
struct dentry *debugfs_rename(struct dentry *old_dir,
struct dentry *old_dentry,
struct dentry *new_dir,
const char *new_name);
struct dentry *debugfs_create_symlink(const char *name,
struct dentry *parent,
const char *target);
A call to debugfs_rename() will give a new name to an existing debugfs
file, possibly in a different directory. The new_name must not exist prior
to the call; the return value is old_dentry with updated information.
Symbolic links can be created with debugfs_create_symlink().
There is one important thing that all debugfs users must take into account:
there is no automatic cleanup of any directories created in debugfs. If a
module is unloaded without explicitly removing debugfs entries, the result
will be a lot of stale pointers and no end of highly antisocial behavior.
So all debugfs users - at least those which can be built as modules - must
be prepared to remove all files and directories they create there. A file
can be removed with:
void debugfs_remove(struct dentry *dentry);
The dentry value can be NULL, in which case nothing will be removed.
Once upon a time, debugfs users were required to remember the dentry
pointer for every debugfs file they created so that all files could be
cleaned up. We live in more civilized times now, though, and debugfs users
can call:
void debugfs_remove_recursive(struct dentry *dentry);
If this function is passed a pointer for the dentry corresponding to the
top-level directory, the entire hierarchy below that directory will be
removed.

--------------------------------------------------
The allyesconfig/allmodconfig/allnoconfig/randconfig variants can
also use the environment variable KCONFIG_ALLCONFIG as a flag or a
filename that contains config symbols that the user requires to be
set to a specific value. If KCONFIG_ALLCONFIG is used without a

"all{yes/mod/no/random}.config" (corresponding to the *config command
that was used) for symbol values that are to be forced. If this file
is not found, it checks for a file named "all.config" to contain forced
values.
This enables you to create "miniature" config (miniconfig) or custom
config files containing just the config symbols that you are interested
in. Then the kernel config system generates the full .config file,
including symbols of your miniconfig file.
This 'KCONFIG_ALLCONFIG' file is a config file which contains

Examples:

----------------------------------------------------------------
STATE OF DEVELOPMENT:
This driver is being developed on the initiative of Piotr Makowski (oponek@gmail.com) and financed by Lars Bergmann.
Development is carried out by Rainer Zimmermann (mail@lightshed.de).
ESI provided a sample Maya44 card for the development work.
However, unfortunately it has turned out difficult to get detailed programming information, so I (Rainer Zimmermann) had to find out some card-specific information by experiment and conjecture. Some information (in particular, several GPIO bits) is still missing.
This is the first testing version of the Maya44 driver released to the alsa-devel mailing list (Feb 5, 2008).
The following functions work, as tested by Rainer Zimmermann and Piotr Makowski:
- playback and capture at all sampling rates
- input/output level
- crossmixing
- line/mic switch
- phantom power switch
- analogue monitor a.k.a bypass
The following functions *should* work, but are not fully tested:
- Channel 3+4 analogue - S/PDIF input switching
- S/PDIF output
- all inputs/outputs on the M/IO/DIO extension card
- internal/external clock selection
*In particular, we would appreciate testing of these functions by anyone who has access to an M/IO/DIO extension card.*
Things that do not seem to work:
- The level meters ("multi track") in 'alsamixer' do not seem to react to signals in (if this is a bug, it would probably be in the existing ICE1724 code).
- Ardour 2.1 seems to work only via JACK, not using ALSA directly or via OSS. This still needs to be tracked down.
DRIVER DETAILS:
the following files were added:
pci/ice1724/maya44.c - Maya44 specific code
pci/ice1724/maya44.h
pci/ice1724/ice1724.patch
pci/ice1724/ice1724.h.patch - PROPOSED patch to ice1724.h (see SAMPLING RATES)
i2c/other/wm8776.c - low-level access routines for Wolfson WM8776 codecs
include/wm8776.h
Note that the wm8776.c code is meant to be card-independent and does not actually register the codec with the ALSA infrastructure.
This is done in maya44.c, mainly because some of the WM8776 controls are used in Maya44-specific ways, and should be named appropriately.
the following files were created in pci/ice1724, simply #including the corresponding file from the alsa-kernel tree:
wtm.h
vt1720_mobo.h
revo.h
prodigy192.h
pontis.h
phase.h
maya44.h
juli.h
aureon.h
amp.h
envy24ht.h
se.h
prodigy_hifi.h
*I hope this is the correct way to do things.*
SAMPLING RATES:
The Maya44 card (or more exactly, the Wolfson WM8776 codecs) allow a maximum sampling rate of 192 kHz for playback and 92 kHz for capture.
As the ICE1724 chip only allows one global sampling rate, this is handled as follows:
* setting the sampling rate on any open PCM device on the maya44 card will always set the *global* sampling rate for all playback and capture channels.
* In the current state of the driver, setting rates of up to 192 kHz is permitted even for capture devices.
*AVOID CAPTURING AT RATES ABOVE 96kHz*, even though it may appear to work. The codec cannot actually capture at such rates, meaning poor quality.
I propose some additional code for limiting the sampling rate when setting on a capture pcm device. However because of the global sampling rate, this logic would be somewhat problematic.
The proposed code (currently deactivated) is in ice1712.h.patch, ice1724.c and maya44.c (in pci/ice1712).
SOUND DEVICES:
PCM devices correspond to inputs/outputs as follows (assuming Maya44 is card #0):
hw:0,0 input - stereo, analog input 1+2
hw:0,0 output - stereo, analog output 1+2
hw:0,1 input - stereo, analog input 3+4 OR S/PDIF input
hw:0,1 output - stereo, analog output 3+4 (and SPDIF out)
NAMING OF MIXER CONTROLS:
(for more information about the signal flow, please refer to the block diagram on p.24 of the ESI Maya44 manual, or in the ESI windows software).
PCM: (digital) output level for channel 1+2
PCM 1: same for channel 3+4
Mic Phantom+48V: switch for +48V phantom power for electrostatic microphones on input 1/2.
Make sure this is not turned on while any other source is connected to input 1/2.
It might damage the source and/or the maya44 card.
Mic/Line input: if switch is is on, input jack 1/2 is microphone input (mono), otherwise line input (stereo).
Bypass: analogue bypass from ADC input to output for channel 1+2. Same as "Monitor" in the windows driver.
Bypass 1: same for channel 3+4.
Crossmix: cross-mixer from channels 1+2 to channels 3+4
Crossmix 1: cross-mixer from channels 3+4 to channels 1+2
IEC958 Output: switch for S/PDIF output.
This is not supported by the ESI windows driver.
S/PDIF should output the same signal as channel 3+4. [untested!]
Digitial output selectors:
These switches allow a direct digital routing from the ADCs to the DACs.
Each switch determines where the digital input data to one of the DACs comes from.
They are not supported by the ESI windows driver.
For normal operation, they should all be set to "PCM out".
H/W: Output source channel 1
H/W 1: Output source channel 2
H/W 2: Output source channel 3
H/W 3: Output source channel 4
H/W 4 ... H/W 9: unknown function, left in to enable testing.
Possibly some of these control S/PDIF output(s).
If these turn out to be unused, they will go away in later driver versions.
Selectable values for each of the digital output selectors are:
"PCM out" -> DAC output of the corresponding channel (default setting)
"Input 1"...
"Input 4" -> direct routing from ADC output of the selected input channel

Machine check
mce=off disable machine check
mce=bootlog Enable logging of machine checks left over from booting.
Disabled by default on AMD because some BIOS leave bogus ones.
If your BIOS doesn't do that it's a good idea to enable though
to make sure you log even machine check events that result
in a reboot. On Intel systems it is enabled by default.
Please see Documentation/x86/x86_64/machinecheck for sysfs runtime tunables.
mce=off
Disable machine check
mce=no_cmci
Disable CMCI(Corrected Machine Check Interrupt) that
Intel processor supports. Usually this disablement is
not recommended, but it might be handy if your hardware
is misbehaving.
Note that you'll get more problems without CMCI than with
due to the shared banks, i.e. you might get duplicated
error logs.
mce=dont_log_ce
Don't make logs for corrected errors. All events reported
as corrected are silently cleared by OS.
This option will be useful if you have no interest in any
of corrected errors.
mce=ignore_ce
Disable features for corrected errors, e.g. polling timer
and CMCI. All events reported as corrected are not cleared
by OS and remained in its error banks.
Usually this disablement is not recommended, however if
there is an agent checking/clearing corrected errors
(e.g. BIOS or hardware monitoring applications), conflicting
with OS's error handling, and you cannot deactivate the agent,
then this option will be a help.
mce=bootlog
Enable logging of machine checks left over from booting.
Disabled by default on AMD because some BIOS leave bogus ones.
If your BIOS doesn't do that it's a good idea to enable though
to make sure you log even machine check events that result
in a reboot. On Intel systems it is enabled by default.
mce=nobootlog
Disable boot machine check logging.
mce=tolerancelevel (number)
mce=tolerancelevel[,monarchtimeout] (number,number)
tolerance levels:
0: always panic on uncorrected errors, log corrected errors
1: panic or SIGBUS on uncorrected errors, log corrected errors
2: SIGBUS or log uncorrected errors, log corrected errors
3: never panic or SIGBUS, log all errors (for testing only)
Default is 1

Implement faster copy_to_user and clear_user methods for CPU
cores where a 8-word STM instruction give significantly higher
memory write throughput than a sequence of individual 32bit stores.
A possible side effect is a slight increase in scheduling latency
between threads sharing the same address space if they invoke
such copy operations with large buffers.
However, if the CPU data cache is using a write-allocate mode,
this option is unlikely to provide any performance gain.
