2015-09-18ALSA: hda - Fix mute-LED fixed modeTakashi Iwai1-9/+12
commit ee52e56e7b12834476cd0031c5986254ba1b6317 upstream. The mute-LED mode control has the fixed on/off states that are supposed to remain on/off regardless of the master switch. However, this doesn't work actually because the vmaster hook is called in the vmaster code itself. This patch fixes it by calling the hook indirectly after checking the mute LED mode.

2013-05-19ALSA: HDA: Fix Oops caused by dereference NULL pointerWang YanQing1-0/+3
commit 2195b063f6609e4c6268f291683902f25eaf9aa6 upstream. The interrupt handler azx_interrupt will call azx_update_rirb, which may call snd_hda_queue_unsol_event, snd_hda_queue_unsol_event will dereference chip->bus pointer. The problem is we alloc chip->bus in azx_codec_create which will be called after we enable IRQ and enable unsolicited event in azx_probe. This will cause Oops due dereference NULL pointer. I meet it, good luck:) [Rearranged the NULL check before the tracepoint and added another NULL check of bus->workq -- tiwai] Signed-off-by: Wang YanQing <udknight@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-10-02ALSA: hda - Fix Oops at codec reset/reconfigTakashi Iwai1-1/+1
commit 07dc59f0988cb54fd87bd373b3b27eb2401dd811 upstream. snd_hda_codec_reset() calls restore_pincfgs() where the codec is powered up again, which eventually tries to resume and initialize via the callbacks of the codec. However, it's the place just after codec free callback, thus no codec callbacks should be called after that. On a codec like CS4206, it results in Oops due to the access in init callback. This patch fixes the issue by clearing the codec callbacks properly after freeing codec.

2012-05-08Revert "ALSA: hda - Set codec to D3 forcibly even if not used"Takashi Iwai1-4/+0
This reverts commit 785f857d1cb0856b612b46a0545b74aa2596e44a. The commit causes a problem with the wrong D3 state after suspend because the call of hda_set_power_state() involves with the power-up sequence, which changes the power_count, and this confuses the resume sequence that checks the power_count as well. Originally, this go-to-D3 sequence should be a simple task without the power-up sequence. But, it'd need some proper sanity checks in the case of power-saved state, so it's not too easy to write now in the 3.4-rc cycle. In short, the safest option now is to revert this affecting commit. Of course, we need to clean up and robustify the power-saving code better for 3.5 kernel. Reported-by: Konstantin Khlebnikov <khlebnikov@openvz.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-03-13ALSA: hda - Add expose_enum_ctl flag to snd_hda_add_vmaster_hook()Takashi Iwai1-1/+4
Since it's not always safe to assume that the vmaster hook is purely the mute-LED control, add the flag indicating whether to expose the mute-LED enum control or not. Currently, conexant codec sets this off for non-HP laptops where EAPD may be used really as EAPD. Signed-off-by: Takashi Iwai <tiwai@suse.de>

Create snd_hda_add_vmaster_hook() and snd_hda_sync_vmaster_hook() helper functions to handle the mute-LED in vmaster hook more commonly. In the former function, a new enum control "Mute-LED Mode" is added. This provides user to choose whether the mute-LED should be turned on/off explicitly or to follow the master-mute status.

2012-03-09ALSA: hda - Initialize vmaster slave volumesTakashi Iwai1-3/+62
When the driver is changed to use vmaster or a new slave element is added by the improvement of the parser code, user may face often the silent output because of the muted slave mixer although Master volume is properly set. And they complain. And I get upset. Although such a mixer element should be initialized via "alsactl init", it'd be more user-friendly if the known output slaves are unmuted and set to 0dB so that user can control the volume only with Master as default. Since Master is still set muted as default even with this change, no risk of the speaker blow up, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-03-07ALSA: hda - Set codec to D3 forcibly even if not usedTakashi Iwai1-0/+4
We've seen a problem with a pop-noise at suspend/resume on a HP machine with ALC269, and it turned out to be an issue that the controller going to D3 while the codec is unused. When the device is once suspended and resumed and kept unused, the driver doesn't initialize the codecs. Instead, the codec chips are set up dynamically at the first usage. Now, suppose the device going to suspend again before the codec is set up. The controller is turned off to D3 while the codec chips are untouched. This caused a pop noise because the codec chip might have been turned on implicitly by the hardware. As a workaround, the codec chip needs to be set to D3 when going to suspend no matter whether it was used or not. Also, for making it happening, the controller has to be always set up in the resume path. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2012-02-29ALSA: hda - Add a fake mute featureTakashi Iwai1-2/+6
Some codecs don't supply the mute amp-capabilities although the lowest volume gives the mute. It'd be handy if the parser provides the mute mixers in such a case. This patch adds an extension amp-cap bit (which is used only in the driver) to represent the min volume = mute state. Also modified the amp cache code to support the fake mute feature when this bit is set but the real mute bit is unset. In addition, conexant cx5051 parser uses this new feature to implement the missing mute controls.

2012-02-03ALSA: hda - Add suffix argument to snd_hda_add_vmaster()Takashi Iwai1-6/+16
In most cases, the slave strings for vmaster are identical between volumes and switches except for "xxx Volume" and "xxx Switch" suffix. Now snd_hda_add_vmaster() takes the optional suffix argument so that each string can be composed with the given suffix, and we can share the slave name strings in both volume and switch calls nicely.

2011-11-26ALSA: hda - Supports more audio streamsTakashi Iwai1-0/+6
So far, the driver supports up to 10 streams. This is a restriction in hda_intel.c and hda_codec.c: in the former, the fixed array size limits the amount, and in the latter, the fixed device-number assignment table (in get_empty_pcm_device()) limits the possibility. This patch reduces the restriction by - using linked list for managing PCM instances in hda_intel.c, and - assigning non-fixed device numbers for the extra devices Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-11-21ALSA: hda - Don't add channel suffix for headphone pin labelsTakashi Iwai1-21/+31
The multiple headphone pins are usually handled as copied from the same source, not as individual channels like front and surround. Thus it'd be more correct to avoid the channel suffix for "Headphone" pin labels in snd_hda_get_pin_label() but give an index number instead. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-11-16ALSA: hda - Cache the jack-detection valueTakashi Iwai1-37/+3
Introduce a table containing the pins and their jack-detection states for avoiding the unnecessary verbs to check the pin status at each time. When the unsol event is enabled via snd_hda_jack_detect_enable(), it automatically adds the given NID to the table. Then the driver supposes that the codec driver will set the dirty flag appropariately when an unsolicited event is invoked for that pin. The behavior for reading other pins that aren't registered in the table doesn't change. Only the pins assigned to the table are cached, so far. In near futre, this table can be extended to use the central place for the unsolicited events of all pins, etc, and eventually include the jack-detect kcontrols that replace the current input-jack stuff.

2011-11-10ALSA: hda - Re-enable the check NO_PRESENCE misc bitTakashi Iwai1-0/+4
We disabled the check of NO_PRESENCE bit of the default pin-config in commit f4419172 temporarily. One problem was that the first implementation was wrong -- the bit after the shift must be checked. However, this would still give many regressions on machines with broken BIOS. They set this bit wrongly even on active pins. A workaround is to check whether all pins contain this bit. As far as I've checked, broken BIOSen set this bit on all pins, no matter whether active or not. In such a case, the driver should ignore this bit check. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-11-10ALSA: hda - Don't add elements of other codecs to vmaster slaveTakashi Iwai1-21/+39
When a virtual mater control is created, the driver looks for slave elements from the assigned card instance. But this may include the elements of other codecs when multiple codecs are on the same HD-audio bus. This works at the first time, but it'll give Oops when it's once freed and re-created via reconfig sysfs. This patch changes the element-look-up strategy to limit only to the mixer elements of the same codec.

The procedure for codec D-state change may have exceptional cases depending on the codec chip, such as a longer delay or suppressing D3. This patch adds a new codec ops, set_power_state() to override the system default function. For ease of porting, snd_hda_codec_set_power_to_all() helper function is extracted from the default set_power_state() function.
