2012-06-18ALSA: hda - Handle open while transitioning to D3.Dylan Reid1-1/+1
This addresses an issue encountered when a pcm is opened while transitioning to low power state (codec->power_on == 1 && codec->power_transition == -1). Add snd_pcm_power_up_d3wait to hda_codec. This function is used to power up from azx_open as opposed to snd_hda_power_up used from codec_exec_verb. When powering up from azx_open, wait for pending power downs to complete, avoiding the power up continuing in parallel with the power down on the work queue. The specific issue seen was with the CS4210 codec, it powers off the ADC and DAC nid in its suspend handler. If it is re-opened before the ~100ms power down process completes, the ADC and DAC nid are initialized while powered down and audio is lost until another suspend/resume cycle.

2012-06-08ALSA: hda - HDMI Audio init all connectors when VGA-switcheroo is offSteven Newbury1-1/+4
When VGA_SWITCHEROO support is enabled hda_intel initialises the HDMI audio device on the current VGA device. When it's not enabled it only initialises the HDMI device on the default VGA adaptor, this means secondary cards get no audio support which is very unhelpful for multi-seat! With this patch, when SUPPORT_VGA_SWITCHEROO is disabled hda_intel initialises all HDMI audio devices, not just the default VGA.

2012-06-08ALSA: hda - Fix uninitialized HDMI controllers with VGA-switcherooTakashi Iwai1-1/+1
When VGA-switcheroo is built in but unused on systems with multiple graphics cards, the initializations of non-default graphics cards are skipped and never enabled (because the switcheroo is activated only when the controller supports). The current behavior is for avoiding the system lockup by accessing the disabled GPU, but due to the recent change in VGA-switcheroo, it determines the state simply by checking with the default VGA device. This is the culprit. Now with the new vga_switcheroo_get_client_state(), we can know the initial state of the bound GPU, thus can determine the initial audio client state more correctly.

2012-05-14ALSA: hda - Check the dead HDMI audio controller by vga-switcherooTakashi Iwai1-2/+52
When a discrete-GPU is disabled by the VGA switcheroo, the corresponding HD-audio controller for HDMI output is also disabled. Such a dead controller still appears in the PCI device list, but you can't access properly any longer (even calling pci_read_config_*() triggers Oops!) which leads the stall of the whole communication of the driver. This patch adds a check of graphics controller at the probe time to see whether it's disabled by vga-switcheroo. If disabled, skip the whole initialization of this controller.

2012-05-09ALSA: HDA: Lessen CPU usage when waiting for chip to respondDavid Henningsson1-2/+4
When an IRQ for some reason gets lost, we wait up to a second using udelay, which is CPU intensive. This patch improves the situation by waiting about 30 ms in the CPU intensive mode, then stepping down to using msleep(2) instead. In essence, we trade some granularity in exchange for less CPU consumption when the waiting time is a bit longer. As a result, PulseAudio should no longer be killed by the kernel for taking up to much RT-prio CPU time. At least not for *this* reason.

2012-05-08ALSA: hda - Always resume the codec immediatelyTakashi Iwai1-13/+1
This is a fix for the problem in commit 785f857d1c, the pop noise issue on some machines with ALC269. The problem was the uninitialized state after the resume due to the delayed resume of the codec chips. In that commit, we tried to fix by forcibly putting the codec to D3 at suspend. But, this still also leaves the uninitialized state after resume, and it _might_ be still problematic with some BIOS. Since the commit turned out to regress another issues, we reverted it in the end. Now, in this fix, try to fix by turning on the codec immediately at the resume path. We need to take care of the power-saving in this case. When the device is woken up at the power-saved state, it should go power-saving again after the resume. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-05-08Revert "ALSA: hda - Set codec to D3 forcibly even if not used"Takashi Iwai1-1/+13
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>

2012-03-07ALSA: hda - Set codec to D3 forcibly even if not usedTakashi Iwai1-13/+1
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>

2012-01-23ALSA: hda - Fix buffer-alignment regression with Nvidia HDMITakashi Iwai1-2/+4
The commit 2ae66c26550cd94b0e2606a9275eb0ab7070ad0e ALSA: hda: option to enable arbitrary buffer/period sizes introduced a regression on machines with Intel controller and Nvidia HDMI. The reason is that the driver modifies the global variable align_buffer_size when an Intel controller is found, and the Nvidia HDMI controller is probed after Intel although Nvidia chips require the aligned buffers.

2011-11-29ALSA: hda_intel - revert a quirk that affect VIA chipsetsMarc Vertes1-1/+0
This quirk sould be reverted. It has the following probems: 1) The quirk was intended to "ASUS MV2-MX SE" motherboards only, but the ID used matches a much broader range, potentially all boards containing a VIA chipset model in the family of vendor VIA 0x1106 and audio device ID 0x3288, which encompasses VIA-VT82xx, VIA-VT1xx and VIA-VT20xx chipsets. 2) VIA chipsets rely on azx_via_get_position() to handle correctly dma transfers during capture. Using POS_FIX_LPIB instead of POS_FIX_VIACOMBO leads to partially corrupted input buffers during capture. The effects of this bug are not immediately visible, it took strong DSP expertise, some expensive signal generator and a spectrum analyzer to identify it and verify correct behaviour using original default. 3) It's almost certain that the quirk did not fix the real problem, if there was one.

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.

The commit ef18beded8ddbaafdf4914bab209f77e60ae3a18 introduced a mechanism to assign the previously used slot for the next reopen of a PCM stream. But the PCM device number isn't always unique (it may have multiple substreams), and also the code doesn't check the stream direction, thus both playback and capture streams share the same device number.

2011-09-28ALSA: hda - Add snoop optionTakashi Iwai1-19/+129
Added a new option "snoop" for the traffic control of the HD-audio controller chip. When set to 0, the non-snooping mode is used with the traffic control bit is set in each stream control register. This may allow better operations in the low power mode, but the actual implementation is depending pretty much on the chipset. As already implemented, more or less each chipset has own snoop-control register bit. Now this setup refers to the snoop option, too. Also, a new VIA chipset may require the non-snooping mode when set so in BIOS. In such a case, the option value is overridden. As default, it's still set to snoop=1 for keeping the same behavior as before. In near future, it'll be set to 0 as default after checking it works in every system well.
