2013-07-21ALSA: replace strict_strto*() with kstrto*()Jingoo Han1-3/+3
The usage of strict_strto*() is not preferred, because strict_strto*() is obsolete. Thus, kstrto*() should be used. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add snd_hda_get_int_hint() helper functionTakashi Iwai1-0/+20
It'll be used in hda_generic.c, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Protect user-defined arrays via mutexTakashi Iwai1-18/+49
The pincfgs, init_verbs and hints set by sysfs or patch might be changed dynamically on the fly, thus we need to protect it. Add a simple protection via a mutex. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-12-07ALSA: Remove the rest of __devinit* in commentsTakashi Iwai1-1/+1
Remove the leftover __devinit* in comments. They have been commented out because they couldn't fit with __dev* although they should have matched. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-08-30ALSA: hda - Clean up CONFIG_SND_HDA_POWER_SAVETakashi Iwai1-2/+2
CONFIG_SND_HDA_POWER_SAVE is no longer an experimental feature and its behavior can be well controlled via the default value and module parameter. Let's just replace it with the standard CONFIG_PM. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-08-09ALSA: hda - Load firmware in hda_intel.cTakashi Iwai1-26/+13
This is a preliminary work for the deferred probing for request_firmware() errors at init. This patch moves the call of request_firmware() to hda_intel.c, and call it in the earlier stage of probing rather than azx_probe_continue().

2011-11-01ALSA: hda_hwdep: Fix possible buffer overflowAlexander Stein1-2/+0
If a line in the firmware file is larger than the given buffer size (and so the firmware file size), size is set to a value larger than the actual buffer size. This results in an overflow in the buffer passed. Signed-off-by: Alexander Stein <alexander.stein@systec-electronic.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-10-31sound: Add export.h for THIS_MODULE/EXPORT_SYMBOL where neededPaul Gortmaker1-0/+1
These aren't modules, but they do make use of these macros, so they will need export.h to get that definition. Previously, they got it via the implicit module.h inclusion. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-09-28ALSA: hda - Allow patching with any vendor/subsystem idsTakashi Iwai1-3/+3
In the ugly real world, there area really broken devices that don't set codec SSID correctly. In such a case, the ID can be random, thus the patching won't work reliably. For applying the patch forcibly to such a device, the driver will skip the vendor and/or subsystem ID checks when zero or a negative number is given in [codec] section.

2009-12-15tree-wide: convert open calls to remove spaces to skip_spaces() lib functionAndré Goddard Rosa1-4/+3
Makes use of skip_spaces() defined in lib/string.c for removing leading spaces from strings all over the tree. It decreases lib.a code size by 47 bytes and reuses the function tree-wide: text data bss dec hex filename 64688 584 592 65864 10148 (TOTALS-BEFORE) 64641 584 592 65817 10119 (TOTALS-AFTER) Also, while at it, if we see (*str && isspace(*str)), we can be sure to remove the first condition (*str) as the second one (isspace(*str)) also evaluates to 0 whenever *str == 0, making it redundant. In other words, "a char equals zero is never a space". Julia Lawall tried the semantic patch (http://coccinelle.lip6.fr) below, and found occurrences of this pattern on 3 more files: drivers/leds/led-class.c drivers/leds/ledtrig-timer.c drivers/video/output.c @@ expression str; @@ ( // ignore skip_spaces cases while (*str && isspace(*str)) { \(str++;\|++str;\) } | - *str && isspace(*str) ) Signed-off-by: André Goddard Rosa <andre.goddard@gmail.com> Cc: Julia Lawall <julia@diku.dk> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: Jeff Dike <jdike@addtoit.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: "H.

2009-11-11ALSA: hda - Add power on/off counterTakashi Iwai1-0/+38
Added the power on/off counter and expose via sysfs files. The sysfs files, power_on_acct and power_off_acct, are created under each codec hwdep sysfs directory (e.g. /sys/class/sound/hwC0D0). The files show the msec length of the codec power-on and power-off, respectively. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-24ALSA: hda - Add patch module optionTakashi Iwai1-19/+217
Added the patch module option to apply a "patch" as a firmware to modify pin configurations or give additional hints to the driver before actually initializing and configuring the codec. This can be used as a workaround when the BIOS doesn't give sufficient information or give wrong information that doesn't match with the real hardware setup, until it's fixed statically in the driver via a quirk. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-05-16ALSA: hda - Split codec->name to vendor and chip name stringsTakashi Iwai1-3/+6
Split the name string in hda_codec struct to vendor_name and chip_name strings to be stored directly from the preset name. Since mostly only the chip name is referred in many patch_*.c, this results in the reduction of many codes in the end. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-03-13ALSA: hda - power up before codec initializationTakashi Iwai1-5/+9
Change the power state of each widget before starting the initialization work so that all verbs are executed properly. Also, keep power-up during hwdep reconfiguration. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-03-02ALSA: hda - Add show for init_verbs and hints sysfs entriesTakashi Iwai1-2/+33

2009-03-02ALSA: hda - Add hint string helper functionsTakashi Iwai1-13/+99
Added snd_hda_get_hint() and snd_hda_get_bool_hint() helper functions to retrieve a hint value. Internally, the hint is stored in a pair of two strings, key and val. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-02-23ALSA: hda - Add pseudo device-locking for clear/reconfigTakashi Iwai1-2/+13

2008-11-27ALSA: hda - Modularize HD-audio driverTakashi Iwai1-1/+1
Split the monolithc HD-audio driver into several pieces: - snd-hda-intel HD-audio PCI controller driver; loaded via udev - snd-hda-codec HD-audio codec bus driver - snd-hda-codec-* Specific HD-audio codec drivers When built as modules, snd-hda-codec (that is invoked by snd-hda-intel) looks up the codec vendor ID and loads the corresponding codec module automatically via request_module(). When built in a kernel, each codec drivers are statically hooked up before probing the PCI. This patch adds appropriate EXPORT_SYMBOL_GPL()'s and the module information for each driver, and driver-linking codes between codec-bus and codec drivers. TODO: - Avoid EXPORT_SYMBOL*() when built-in kernel - Restore __devinit appropriately depending on the condition Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-11-27ALSA: hda - Fix PCM reconfigureTakashi Iwai1-1/+1
The reconfiguration of PCM affected all PCM streams on the bus, but this this should be done rather only for the target codec. This patch does the following: - introduce bitmap indicating the PCM device usages on a hda_bus - refactor the PCM build functions - fix __devinit prefix in some fucntions - add a proper ifdef around HDA-reconfig-specific functions Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-11-21ALSA: hda - Make CONFIG_SND_HDA_RECONFIG for codec reconfigurationTakashi Iwai1-0/+4
Make the codec re-configuration feature selectable via Kconfig, CONFIG_SND_HDA_RECONFIG. Also mark it as experimental (as it really is). Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-10-13ALSA: hda - Add hints for reconfigTakashi Iwai1-0/+34
This patch adds the "hints" for reconfiguring codecs. The hints are simply string arrays and can be freely used/parsed by the codec patch. The hints can be input via hwdep sysfs files. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-10-13ALSA: hda - Add init_verbs entriesTakashi Iwai1-0/+37
This patch enables the additional init verbs for each codec. The verbs can be entered via hwdep sysfs file. These verbs are executed at reconfiguring the codec for non-standard setups like overriding the pin-defcfg. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-10-13ALSA: hda - Add sysfs entries to hwdep devicesTakashi Iwai1-0/+157
Added the sysfs entries to hwdep devices so that the new features like reconfiguration can be done via sysfs. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-05-27[ALSA] Replace CONFIG_SND_DEBUG_DETECT with CONFIG_SND_DEBUG_VERBOSETakashi Iwai1-1/+1

2008-01-31[ALSA] Remove sound/driver.hTakashi Iwai1-1/+0
This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.
