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

|
||||
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.

KCONFIG_ALLCONFIG

--------------------------------------------------

(partially based on lkml email from/by Rob Landley, re: miniconfig)
|
||||
--------------------------------------------------
|
||||
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
|
||||
filename, "make *config" checks for a file named
|
||||
"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
|
||||
(usually a subset of all) preset config symbols. These variable
|
||||
settings are still subject to normal dependency checks.
|
||||
|
||||
Examples:
|
||||
KCONFIG_ALLCONFIG=custom-notebook.config make allnoconfig
|
||||
or
|
||||
KCONFIG_ALLCONFIG=mini.config make allnoconfig
|
||||
or
|
||||
make KCONFIG_ALLCONFIG=mini.config allnoconfig
|
||||

Environment variables in 'menuconfig'
|
||||
|
||||
KCONFIG_ALLCONFIG
|
||||
--------------------------------------------------
|
||||
(partially based on lkml email from/by Rob Landley, re: miniconfig)
|
||||
--------------------------------------------------
|
||||
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
|
||||
filename, "make *config" checks for a file named
|
||||
"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 dependencies of your miniconfig file, based on the miniconfig
|
||||
file.
|
||||
|
||||
This 'KCONFIG_ALLCONFIG' file is a config file which contains
|
||||
(usually a subset of all) preset config symbols. These variable
|
||||
settings are still subject to normal dependency checks.
|
||||
|
||||
Examples:
|
||||
KCONFIG_ALLCONFIG=custom-notebook.config make allnoconfig
|
||||
or
|
||||
KCONFIG_ALLCONFIG=mini.config make allnoconfig
|
||||
or
|
||||
make KCONFIG_ALLCONFIG=mini.config allnoconfig
|
||||
|
||||
These examples will disable most options (allnoconfig) but enable or
|
||||
disable the options that are explicitly listed in the specified
|
||||
mini-config files.
|
||||
|
||||
KCONFIG_NOSILENTUPDATE
|
||||
--------------------------------------------------
|
||||
If this variable has a non-blank value, it prevents silent kernel
|
||||
config udpates (requires explicit updates).
|
||||
|
||||
KCONFIG_CONFIG
|
||||
--------------------------------------------------
|
||||
This environment variable can be used to specify a default kernel config
|
||||
file name to override the default name of ".config".
|
||||
|
||||
KCONFIG_OVERWRITECONFIG
|
||||
--------------------------------------------------
|
||||
If you set KCONFIG_OVERWRITECONFIG in the environment, Kconfig will not
|
||||
break symlinks when .config is a symlink to somewhere else.
|
||||
|
||||
KCONFIG_NOTIMESTAMP
|
||||
--------------------------------------------------
|
||||
If this environment variable exists and is non-null, the timestamp line
|
||||
in generated .config files is omitted.
|
||||
|
||||
KCONFIG_AUTOCONFIG
|
||||
--------------------------------------------------
|
||||
This environment variable can be set to specify the path & name of the
|
||||
"auto.conf" file. Its default value is "include/config/auto.conf".
|
||||
|
||||
KCONFIG_AUTOHEADER
|
||||
--------------------------------------------------
|
||||
This environment variable can be set to specify the path & name of the
|
||||
"autoconf.h" (header) file. Its default value is "include/linux/autoconf.h".
|
||||

||||

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:

||||
|
||||

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:

|
||||
*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
