2016-03-04ALSA: hda - hdmi defer to register acomp eld notifierLibin Yang1-12/+12
Defer to register acomp eld notifier until hdmi audio driver is fully ready. After registering eld notifier, gfx driver can use this callback function to notify audio driver the monitor connection event. However this action may happen when audio driver is adding the pins or doing other initialization. This is not always safe, however. For example, using per_pin->lock before the lock is initialized. Let's register the eld notifier after the initialization is done. Signed-off-by: Libin Yang <libin.yang@linux.intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

This patch applies the microphone-related fix created for the Acer Aspire E1-572 to the E1-472 as well, as it uses the same Realtek ALC282 CODEC and demonstrates the same issues. This patch allows an external, headset microphone to be used and limits the gain on the (quite noisy) internal microphone.

2016-02-26ALSA: hda - Loop interrupt handling until really clearedTakashi Iwai1-21/+26
Currently the interrupt handler of HD-audio driver assumes that no irq update is needed while processing the irq. But in reality, it has been confirmed that the HW irq is issued even during the irq handling. Since we clear the irq status at the beginning, process the interrupt, then exits from the handler, the lately issued interrupt is left untouched without being properly processed. This patch changes the interrupt handler code to loop over the check-and-process. The handler tries repeatedly as long as the IRQ status are turned on, and either stream or CORB/RIRB is handled. For checking the stream handling, snd_hdac_bus_handle_stream_irq() returns a value indicating the stream indices bits. Other than that, the change is only in the irq handler itself.

HP EliteBook 755 G2 with ALC3228 (ALC280) codec [103c:221c] requires the known fixup (ALC269_FIXUP_HEADSET_MIC) for making the headset mic working.

2016-02-22ALSA: hda - Apply clock gate workaround to Skylake, tooTakashi Iwai1-9/+7
Some Skylake machines show the codec probe errors in certain situations, e.g. HP Z240 desktop fails to probe the onboard Realtek codec at reloading the snd-hda-intel module like: snd_hda_intel 0000:00:1f.3: spurious response 0x200:0x2, last cmd=0x000000 snd_hda_intel 0000:00:1f.3: azx_get_response timeout, switching to polling mode: lastcmd=0x000f0000 snd_hda_intel 0000:00:1f.3: No response from codec, disabling MSI: last cmd=0x000f0000 snd_hda_intel 0000:00:1f.3: Codec #0 probe error; disabling it... hdaudio hdaudioC0D2: no AFG or MFG node found snd_hda_intel 0000:00:1f.3: no codecs initialized Also, HP G470 G3 suffers from the similar problem, as reported in bugzilla below. On this machine, the codec probe error appears even at a fresh boot. As Libin suggested, the same workaround used for Broxton in the commit [6639484ddaf6: ALSA: hda - disable dynamic clock gating on Broxton before reset] can be applied for Skylake in order to fix this problem. The Intel HW team also confirmed that this is needed for SKL. This patch makes the workaround applied to both SKL and BXT platforms. The referred macros are moved and one superfluous macro (IS_BROXTON()) is another one (IS_BXT()) as well.

2016-02-15ALSA: hda - Cancel probe work instead of flush at removeTakashi Iwai1-2/+2
The commit [991f86d7ae4e: ALSA: hda - Flush the pending probe work at remove] introduced the sync of async probe work at remove for fixing the race. However, this may lead to another hangup when the module removal is performed quickly before starting the probe work, because it issues flush_work() and it's blocked forever. The workaround is to use cancel_work_sync() instead of flush_work() there.

2016-02-09ALSA: hda - Fix bad dereference of jack objectTakashi Iwai7-10/+13
The hda_jack_tbl entries are managed by snd_array for allowing multiple jacks. It's good per se, but the problem is that struct hda_jack_callback keeps the hda_jack_tbl pointer. Since snd_array doesn't preserve each pointer at resizing the array, we can't keep the original pointer but have to deduce the pointer at each time via snd_array_entry() instead. Actually, this resulted in the deference to the wrong pointer on codecs that have many pins such as CS4208. This patch replaces the pointer to the NID value as the search key. As an unexpected good side effect, this even simplifies the code, as only NID is needed in most cases. Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

This reverts commit 0c25ad80408e95e0a4fbaf0056950206e95f726f. The original commit disabled the aamixer path due to the noise problem, but it turned out that some mobo with the same PCI SSID doesn't suffer from the issue, and the disabled function (analog loopback) is still demanded by users. Since the recent commit [e7fdd52779a6: ALSA: hda - Implement loopback control switch for Realtek and other codecs], we have the dynamic mixer switch to enable/disable the aamix path, and we don't have to disable the path statically any longer. So, let's revert the disablement, so that only the user suffering from the noise problem can turn off the aamix on the fly.

2016-01-20ALSA: hda - Flush the pending probe work at removeTakashi Iwai1-1/+9
As HD-audio driver does deferred probe internally via workqueue, the driver might go into the mixed state doing both probe and remove when the module gets unloaded during the probe work.

Currently HD-audio driver on Intel Skylake or Broxteon gives an error message when binding with i915 audio component fails. However, this isn't any serious error on a system without Intel graphics. Indeed there are such systems, where a third-party codec (e.g. Creative) is put on the mobo while using other discrete GPU (e.g. Nvidia). Printing a kernel "error" message is overreaction in such a case. This patch downgrades the print level for that message. For systems that mandate the i915 binding (e.g. Haswell or Broadwell HDMI/DP), another kernel error message is shown in addition to make clear what went wrong.

Lenovo Thinkpads with Realtek codecs may still have some loud crackling noises at reboot/shutdown even though a few previous fixes have been applied. It's because the previous fix (disabling the default shutup callback) takes effect only at transition of the codec power state. Meanwhile, at reboot or shutdown, we don't take down the codec power as default, thus it triggers the same problem unless the codec is powered down casually by runtime PM.

2015-12-15ALSA: hda - Increase default bdl_pos_adj for Baytrail/BraswellTakashi Iwai1-0/+9
Intel Atom processors seem to have a problem at recording when bdl_pos_adj is set to an odd value. When a value like 1 is used, it may drop the samples unexpectedly. Actually, for the old Atoms, we used to set AZX_DRIVER_SCH type, and this assigns 32 as default. Meanwhile the newer chips, Baytrail and Braswell, are set as AZX_DRIVER_PCH, and the lower default value, 1, is assigned. This patch changes the default values for these chipsets to a safer default, 32, again. Since changing the driver type (AZX_DRIVER_XXX) leads to the rename of the driver string, it would result in a possible regression. So, we can't change the type. Instead, in this patch, manual (ugly) PCI ID checks are added on top. A drawback by this increase is the slight increase of the latency, but it's a sub-ms order in normal situations, so mostly negligible.

2015-12-15ALSA: hda - Clean up the code to check bdl_pos_adj optionTakashi Iwai3-16/+18
Just a minor cleanup; instead of passing an array, pass the assigned bdl_pos_adj option value directory in struct azx. Also split the code to get the default bdl_pos_adj value for the change that will follow after this. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-12-10ALSA: hda - Move audio component accesses to hdac_i915.cTakashi Iwai1-43/+26
A couple of i915_audio_component ops have been added and accessed directly from patch_hdmi.c. Ideally all these should be factored out into hdac_i915.c. This patch does it, adds two new helper functions for setting N/CTS and fetching ELD bytes. One bonus is that the hackish widget vs port mapping is also moved to hdac_i915.c, so that it can be fixed / enhanced more cleanly.

2015-12-10ALSA: hda - Use component ops for i915 HDMI/DP audio jack handlingTakashi Iwai1-14/+97
Since we have a new audio component ops to fetch the current ELD and state now, we can reduce the usage of unsol event of HDMI/DP pins. The unsol event isn't only unreliable, but it also needs the power up/down of the codec and link at each time, which is a significant power and time loss. In this patch, the jack creation and unsol/jack event handling are modified to use the audio component for the dedicated Intel chips. The jack handling got slightly more codes than a simple usage of hda_jack layer since we need to deal directly with snd_jack object; the hda_jack layer is basically designed for the pin sense read and unsol events, both of which aren't used any longer in our case.

2015-12-10ALSA: hda - Fix superfluous HDMI jack repollTakashi Iwai1-1/+4
The recent commit [e90247f9fcee: ALSA: hda - Split ELD update code from hdmi_present_sense()] rewrote the HDMI jack handling code, but a slight behavior change sneaked in unexpectedly. When the jack isn't connected, it tries repoll unnecessarily. This patch addresses the flaw, to the right behavior as before.

2015-12-10ALSA: hda - Allow i915 binding later in codec driverTakashi Iwai2-3/+14
Due to the recent change, HDA controller driver for Intel PCH tries to bind i915 audio component always at the probe time no matter whether HDMI/DP codec is found. This is, however, superflulous for old chipsets (e.g. on IVB) where they don't have always the HDMI/DP codecs but often have only a discrete GPU instead. For the newer chipsets, we need already the i915 binding from the beginning due to power well control. Meanwhile, for older chipsets where we don't need power well, we don't need the i915 binding at the controller level. This patch removes again the i915 binding in the HDA controller driver for old Intel PCHs, but adds the binding in HDMI/DP codec driver instead. This allows still the use of the direct notification from the graphics driver while we can avoid the unnecessary load of i915 driver for machines only with another GPU.
