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.

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
Added the show method for init_verbs and hints hwdep sysfs entries. They show the current values. Signed-off-by: Takashi Iwai <tiwai@suse.de>
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
Added the pseudo device-locking using card->shutdown flag to avoid the crash via clear/reconfig during operations. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-02-23ALSA: hda - Rename {override,cur}_pin with {user,driver}_pinTakashi Iwai1-16/+16
Rename from override_pin and cur_pin with user_pin and driver_pin, respectively, to be a bit more intuitive. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-02-20ALSA: hda - Add generic pincfg initializationTakashi Iwai1-0/+66
Added the generic pincfg cache and save/restore functions. Also introduced the pin-overriding via hwdep sysfs. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-02-20ALSA: hda - Fix parse of init_verbs sysfs entryTakashi Iwai1-7/+8
Fixed the parse of init_verbs hwdep sysfs entry. Simplieied using sscanf. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-02-12ALSA: hda - Register (new) devices at reconfigTakashi Iwai1-1/+1
The devices that have been newly added during reconfig must be registered. Otherwise they won't be visible to user-space. Signed-off-by: Takashi Iwai <tiwai@suse.de>
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
Replace CONFIG_SND_DEBUG_DETECT with CONFIG_SND_DEBUG_VERBOSE to represent its meaning more better. This config isn't provided only for the detection but for more verbose debug prints in general. Signed-off-by: Takashi Iwai <tiwai@suse.de>
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.

2007-10-16[ALSA] hda-intel - Fix compile warning in snd_hwdep_ioctl_compat()Takashi Iwai1-1/+1
Fix missing cast: sound/pci/hda/hda_hwdep.c:86: warning: passing argument 4 of 'hda_hwdep_ioctl' makes integer from pointer without a cast Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2007-10-16[ALSA] hda-intel - Add hwdep interfaceTakashi Iwai1-0/+122
Added a hwdep interface for each codec (enabled per kconfig). This interface can be used for reading/writing HD-audio verbs and other purposes as future extensions. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
