+For these reasons, the "summary" must be no more than 70-75

+should do.
+
+The "summary phrase" may be prefixed by tags enclosed in square
+brackets: "Subject: [PATCH tag] <summary phrase>". The tags are not

+should be treated. Common tags might include a version descriptor if
+the multiple versions of the patch have been sent out in response to
+comments (i.e., "v1, v2, v3"), or "RFC" to indicate a request for
+comments. If there are four patches in a patch series the individual

+that developers understand the order in which the patches should be
+applied and that they have reviewed or applied all of the patches in

+another moment discussing this issue. When writing a changelog, you should
+bear in mind that a number of different people will be reading your words.
+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

+general, the more you can put yourself into the shoes of everybody who will

+
+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.

+keep here as reference -- tiwai
+
+----------------------------------------------------------------
+
+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

+ * { OUT => SFN } Change CON first, so new data will not glitch
+ * { OUT => IN } Change CON first, so new data will not glitch
+ * { SFN => IN } Change CON first
+ * { SFN => OUT } Change DAT first, so new data will not glitch [1]
+ *
+ * We do not currently deal with the UP registers as these control

- * The three states the pin can be are {IN,OUT,SFN} which gives us 9

- * { IN => OUT } Change DAT first
- * { IN => SFN } Change CON first
- * { OUT => SFN } Change CON first, so new data will not glitch
- * { OUT => IN } Change CON first, so new data will not glitch
- * { SFN => IN } Change CON first
- * { SFN => OUT } Change DAT first, so new data will not glitch [1]
- *
- * We do not currently deal with the UP registers as these control

+ help
+ This kernel feature is useful for number crunching applications
+ that may need to compute untrusted bytecode during their
+ execution. By using pipes or other transports made available to
+ the process as file descriptors supporting the read/write
+ syscalls, it's possible to isolate those applications in
+ their own address space using seccomp. Once seccomp is
+ enabled via /proc/<pid>/seccomp, it cannot be disabled
+ and the task is only allowed to execute a few safe syscalls
+ defined by each seccomp mode.
+
+ If unsure, say Y.

- If you have a SCSI device that supports more than one LUN (Logical
- Unit Number), e.g. a CD jukebox, and only one LUN is detected, you
- can say Y here to force the SCSI driver to probe for multiple LUNs.
- A SCSI device with multiple LUNs acts logically like multiple SCSI
- devices. The vast majority of SCSI devices have only one LUN, and
- so most people can say N here. The max_luns boot/module parameter
- allows to override this setting.
+ Some devices support more than one LUN (Logical Unit Number) in order
+ to allow access to several media, e.g. CD jukebox, USB card reader,
+ mobile phone in mass storage mode. This option forces the kernel to
+ probe for all LUNs by default. This setting can be overriden by
+ max_luns boot/module parameter. Note that this option does not affect
+ devices conforming to SCSI-3 or higher as they can explicitely report
+ their number of LUNs. It is safe to say Y here unless you have one of
+ those rare devices which reacts in an unexpected way when probed for
+ multiple LUNs.

+ *
+ * This file is released under the GPLv2.

+ * CUSE enables character devices to be implemented from userland much
+ * like FUSE allows filesystems. On initialization /dev/cuse is
+ * created. By opening the file and replying to the CUSE_INIT request
+ * userland CUSE server can create a character device. After that the
+ * operation is very similar to FUSE.
+ *
+ * A CUSE instance involves the following objects.
+ *
+ * cuse_conn : contains fuse_conn and serves as bonding structure
+ * channel : file handle connected to the userland CUSE server
+ * cdev : the implemented character device
+ * dev : generic device for cdev
+ *
+ * Note that 'channel' is what 'dev' is in FUSE. As CUSE deals with
+ * devices, it's called 'channel' to reduce confusion.
+ *
+ * channel determines when the character device dies. When channel is
+ * closed, everything begins to destruct. The cuse_conn is taken off
+ * the lookup table preventing further access from cdev, cdev and
+ * generic device are removed and the base reference of cuse_conn is
+ * put.
+ *
+ * On each open, the matching cuse_conn is looked up and if found an
+ * additional reference is taken which is released when the file is
+ * closed.

- * The permissions for the special ACL entries (u::, g::[m::], o::) are
- * actually stored in the file mode (if there is both a group and a mask,
- * the group is stored in the ACL entry and the mask is stored on the file).
- * This allows the mode to remain automatically in sync with the ACL without
- * the need for a call-back to the ACL system at every point where the mode
- * could change. This function takes the permissions from the specified mode
- * and places it in the supplied ACL.
- *
- * This implementation draws its validity from the fact that, when the ACL
- * was assigned, the mode was copied from the ACL.
- * If the mode did not change, therefore, the mode remains exactly what was
- * taken from the special ACL entries at assignment.
- * If a subsequent chmod() was done, the POSIX spec says that the change in
- * mode must cause an update to the ACL seen at user level and used for
- * access checks. Before and after a mode change, therefore, the file mode
- * most accurately reflects what the special ACL entries should permit/deny.
- *
- * CAVEAT: If someone sets the SGI_ACL_FILE attribute directly,
- * the existing mode bits will override whatever is in the
- * ACL. Similarly, if there is a pre-existing ACL that was
- * never in sync with its mode (owing to a bug in 6.5 and
- * before), it will now magically (or mystically) be
- * synchronized. This could cause slight astonishment, but
- * it is better than inconsistent permissions.
- *
- * The supplied ACL is a template that may contain any combination
- * of special entries. These are treated as place holders when we fill
- * out the ACL. This routine does not add or remove special entries, it
- * simply unites each special entry with its associated set of permissions.

+Arch requirements
+-----------------
+
+If your architecture does not have hardware performance metrics, you can
+still use the generic software counters based on hrtimers for sampling.
+
+So to start with, in order to add HAVE_PERF_COUNTERS to your Kconfig, you
+will need at least this:
+ - asm/perf_counter.h - a basic stub will suffice at first
+ - support for atomic64 types (and associated helper functions)
+ - set_perf_counter_pending() implemented
+
+If your architecture does have hardware capabilities, you can override the
+weak stub hw_perf_counter_init() to register hardware counters.
