2009-03-18ALSA: hda - Workaround for buggy DMA position on ATI controllersTakashi Iwai
The position-buffer on ATI controllers are unreliable as well as on VIA chips, thus the same workaround for DMA position reading as VIA is useful for ATI. Cc: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-03-18ALSA: hda - Fix DMA mask for ATI controllersTakashi Iwai
ATI controllers (at least some SB0600 models) appear buggy to handle 64bit DMA. As a workaround, reset GCAP bit0 and let the driver to use only 32bit DMA on these controllers. Cc: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-03-02ALSA: hda - Remove Toshiba probe_mask quirkTakashi Iwai
Revert the Toshiba probe_mask quirk for 2.6.29 kernel (commit 38f1df27e3191d76e983cb9c6b4392582fd32fda). In the current tree, the digital-only codec is handled properly so no codec conflict should occur. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-03-02ALSA: hda - Add probe_mask default for Toshiba laptop with ALC268Takashi Iwai
Some Toshiba laptops have another ALC268 codec on slot#3 that conflicts with the primary codec. The codec#3 is for the digital I/O, and should be fixed by the driver, but it'd need a bunch of changes. So, let's fix the probe problem temporarily by setting the default probe_mask value.

2009-02-13ALSA: hda - Add forced codec-slots for ASUS W5FTakashi Iwai
ASUS W5F needs the fixed codec-slots to probe to override the BIOS problem. Tested-by: Giovanni Moser Frainer <giovanni@redix.com.br> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-02-13ALSA: hda - Allow fixed codec-probe maskTakashi Iwai
Some devices have broken BIOS and they don't set the codec probe-bit properly after cleared by the driver. This makes the driver skipping the necessary codec slots. Since BIOS update isn't always easy, now the semantics of probe_mask option is changed a bit. When it contains the bit 8 (0x100), the lower bits are used to probe that slots regardless of codec-probe bits returned by the hardware. For example, probe_mask=0x103 will force to probe the codec slot #0 and #1. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-01-12ALSA: hda - Use own workqueueTakashi Iwai
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.

2008-12-19ALSA: hda - Add probe_only optionTakashi Iwai
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>

2008-12-11ALSA: hda - Fix a compile warning when CONFIG_PM=nTakashi Iwai
Fixed the compile warning regarding the unused function when built with CONFIG_PM=n: sound/pci/hda/hda_intel.c:1905: warning: ‘snd_hda_codecs_inuse’ defined but not used snd_hda_codecs_inuse() is used only in the resume callback. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-12-07Sound: hda - Restore PCI configuration space with interrupts offRafael J. Wysocki
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.

2008-11-27ALSA: hda - make some functions staticTakashi Iwai

2008-11-24ALSA: hda - Add probe_mask quirk for Medion MD96630Takashi Iwai
Medion MD96630 has ALC268 codec on slot#2 although it's not used for any purpose. This codec conflicts with the primiary codec ALC888 on slot#0, and gives mixer errors. This patch adds a corresponding entry to probe_mask blacklist. Reference: Novell bnc#412528 https://bugzilla.novell.com/show_bug.cgi?id=412528 Signed-off-by: Takashi Iwai <tiwai@suse.de>

2008-11-06ALSA: hda - Make codec-probing more robustTakashi Iwai
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>

2008-10-29ALSA: hda - Add reboot notifierTakashi Iwai
The current snd-hda-intel driver seems blocking the power-off on some devices like eeepc. Although this is likely a BIOS problem, we can add a workaround by disabling IRQ lines before power-off operation. This patch adds the reboot notifier to achieve it.

2008-06-13ALSA: hda - Add a warning if pending IRQ is foundTakashi Iwai

2008-06-13ALSA: hda - Fix bdl_pos_adj value for ATI SB chipsetsTakashi Iwai
ATI SB controllers seem to report the DMA ahead in the amount of FIFO. Thus bdl_pos_adj should be 32 for them as default. Also, the default value is set to -1, which means to make the driver to choose the appropriate value. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
2008-06-13ALSA: hda - bdl_pos_adj option to each instanceTakashi Iwai

2008-06-13ALSA: hda - remove position_fix=3Takashi Iwai
position_fix=3 is the option to correct the DMA position with the FIFO size. But, it never worked correctly, and we have now more other workarounds for the DMA position fixes. Thus better to remove it. Also, change POS_FIX_NONE to POS_FIX_LPIB to represent its real role better. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
2008-06-13ALSA: hda - Add bdl_pos_adj optionTakashi Iwai
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.
