* ALSA: hda - Limit codec-verb retry to limited hardwaresTakashi Iwai2009-06-01
| | | | | | | | | | | The reset of a BUS controller during operations is somehow risky and shouldn't be done inevitably for devices that have apparently no such codec-communication problems. This patch adds the check of the hardware and limits the bus-reset capability. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: hda - Add codec bus reset and verb-retry at critical errorsTakashi Iwai2009-06-01
| | | | | | | | | | | | Some machines machine cause a severe CORB/RIRB stall in certain weird conditions, such as PA access at the start up together with fglrx driver. This seems unable to be recovered without the controller reset. This patch allows the bus controller reset at critical errors so that the communication gets recovered again.

* ALSA: hda - Split codec->name to vendor and chip name stringsTakashi Iwai2009-05-16
| | | | | | | | | 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>
* ALSA: hda - Retry codec-verbs at errorsTakashi Iwai2009-04-21
| | | | | | | | | | | | | The current error-recovery scheme for the codec communication errors doesn't work always well. Especially falling back to the single-command mode causes the fatal problem on many systems. In this patch, the problematic verb is re-issued again after the error (even with polling mode) instead of the single-cmd mode. The single-cmd mode will be used only when specified via the command option explicitly, mainly just for testing. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: hda - Fix misc workqueue issuesTakashi Iwai2009-02-05
| | | | | | | | | | Some fixes regarding snd-hda-intel workqueue: - Use create_singlethread_workqueue() instead of create_workqueue() as per-CPU work isn't required. - Allocate workq name string properly - Renamed the workq name to "hd-audio*" to be more obvious. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: hda - Use own workqueueTakashi Iwai2009-01-12
| | | | | | | | | | | | | | snd-hda-intel driver used schedule_work() fot the delayed DMA pointer updates, but this has several potential problems: - it may block other eventsd works longer - it may deadlock when probing fails and flush_scheduled_work() is called during probe callback (as probe callback itself could be invoked from eventd) This patch adds an own workq for each driver instance to solve these problems.

* ALSA: hda - Add probe_only optionTakashi Iwai2008-12-19
| | | | | | | | | | | | | Added probe_only module option to hd-audio driver. This option specifies whether the driver creates and initializes the codec-parser after probing. When this option is set, the driver skips the codec parsing and initialization but gives you proc and other accesses. It's useful to see the initial codec state for debugging. The default of this value is off, so the default behavior is as same as before. Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | The global functions in hda_codec.c and other core parts are only for HD-audio codec and controller drivers. When the HD-audio driver is built in kernel, all stuff have to be statically linked, thus we don't need any exports. This patch introduces a conditional macro to do export only when needed.

| * ALSA: hda - Modularize HD-audio driverTakashi Iwai2008-11-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ALSA: hda - Fix PCM reconfigureTakashi Iwai2008-11-27
| | | | | | | | | | | | | 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>

* ALSA: hda - Fix double free of jack instancesTakashi Iwai2008-11-21
| | | | | | | | | | | | | | | The jack instances created in patch_sigmatel.c may be double-freed. The device management code checks the invalid element, and thus there is no real breakage, but it spews annoying warning messages. But, we can't simply remove the release calls of these jack instances because they have to be freed when the codec is re-configured. Now, a new flag, bus->shutdown is introduced to indicate that the bus is really being unloaded, i.e. the objects managed by the device manager will be automatically deleted. We release these objects only when this flag isn't set. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: hda - Don't reset SPDIF in each status changeTakashi Iwai2008-08-13
| | | | | | | | | | | The SPDIF output is toggled at each time any SPDIF status bits are changed because of the known problems on some codecs. But, this also results in loosing the sync, and the problem is more obvious on HDMI output over SPDIF. Since the toggle is necessary only for some codecs, we should check whether this workaround is needed and skip if unnecessary.

* [ALSA] hda-intel - Fix PCM device number assignmentTakashi Iwai2008-04-24
| | | | | | | | | | | | | | | | | In the current scheme, PCM device numbers are assigned incrementally in the order of codecs. This causes problems when the codec number is irregular, e.g. codec #0 for HDMI and codec #1 for analog. Then the HDMI becomes the first PCM, which is picked up as the default output device. Unfortuantely this doesn't work well with normal setups. This patch introduced the fixed device numbers for the PCM types, namely, analog, SPDIF, HDMI and modem. The PCM devices are assigned according to the corresponding PCM type. After this patch, HDMI will be always assigned to PCM #3, SPDIF to PCM #1, and the first analog to PCM #0, etc. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* [ALSA] hda-intel - Add workarounds for STAC codecsTakashi Iwai2008-01-31
| | | | | | | | | | | Some machines with STAC codecs seem to have problems (e.g. no audible playback) when the delay in codec-read routine is too short. I still don't figure out which command sequence causes this problem (due to lack of test hardware), but it's known that increasing the delay fixes. So, added a stupid workaround here temporarily...

* [ALSA] hda-intel - Fix resume logic, when dynamic power managment is onMaxim Levitsky2007-10-16
| | | | | | | | | | | | | | | Comment in hda_intel.c states that 'the explicit resume is needed only when POWER_SAVE isn't set', but this is not true. There is no code that will automaticly power up the codec on resume, but only code that powers it up when user accesses it.

* [ALSA] hda-intel - Add POWER_SAVE optionTakashi Iwai2007-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | Added CONFIG_SND_HDA_POWER_SAVE kconfig. It's an experimental option to achieve an aggressive power-saving. With this option, the driver will turn on/off the power of each codec and controller chip dynamically on demand. The patch introduces a new module option 'power_save'. It specifies the second of time-out for automatic power-down. As default, it's 10 seconds. Setting 0 means to suppress the power-saving feature. The codec may have analog-input loopbacks, which are usually represented by mixer elements such as 'Mic Playback Switch' or 'CD Playback Switch'. When these are on, we cannot turn off the mixer and the codec chip has to be kept on. For bookkeeping these states, a new codec-callback is introduced. For the bus-controller side, a new callback pm_notify is introduced, which can be used to turn on/off the contoller appropriately. Note that this power-saving might cause slight click-noise at power-on/off. Also, it might take some time to wake up the codec, and might even drop some tones at the very beginning. This seems to be the side-effect of turning off the controller chip. This turn-off of the controller can be disabled by undefining HDA_POWER_SAVE_RESET_CONTOLLER in hda_intel.c.
