* Revert "Sound: hda - Restore PCI configuration space with interrupts off"Takashi Iwai2009-02-16
| | | | | | | | | | | | | This reverts commit 32e176c14d7a425b681ef003c9061001ddb7fc7b. That commit caused a regression with suspend on Thinkpad SL300.

* 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.

| * Sound: hda - Restore PCI configuration space with interrupts offRafael J. Wysocki2008-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | Move the restoration of the standard PCI configuration registers in the snd_hda_intel driver to a ->resume_early() callback executed with interrupts disabled, since doing that with interrupts enabled may lead to problems in some cases. This patch addresses the regression from 2.6.26 tracked as http://bugzilla.kernel.org/show_bug.cgi?id=12121 . Signed-off-by: Rafael J.

* | 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>

* | | ALSA: hda - Make codec-probing more robustTakashi Iwai2008-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an error occurs during the codec probing, typically accessing to an non-existing codec slot, the controller chip gets often screwed up and can no longer communicate with the codecs. This patch adds a preparation phase just to probe codec addresses before actually creating codec instances. If any error occurs during this probing phase, the driver resets the controller to recover. This will (hopefully) fix the famous "single_cmd" errors. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: hda - Add bdl_pos_adj optionTakashi Iwai2008-06-13
| | | | | | | | | | | | | | | | | | | | Added a new option, bdl_pos_adj, to adjust the delay of IRQ-wakeup timing. Most HD-audio hardwares have a problem that a BDL IRQ is issued before actually the data and the DMA pointer are updated. We have already a mechanism to force to delay snd_pcm_period_elapsed() calls via workq, but this costs much CPU, and typically the delay is within one sample. Thus, it's more clever to adjust the BDL entries instead. The new option adds the size of the delay in frames. As default, it's set to 1 -- that is, one sample delay. Even the hardware is really correct, one sample delay is relatively harmless in comparison with reporting wrong positions.
