* ALSA: hda/realtek - Add auto-mute quirk for HP Spectre x360 laptopGirija Kumar Kasinadhuni2018-12-051-0/+7
| | | | | | | | | | | | | | commit e8ed64b08eddc05043e556832616a478bbe4bb00 upstream. This device makes a loud buzzing sound when a headphone is inserted while playing audio at full volume through the speaker.

* ALSA: hda/realtek - fix the pop noise on headphone for lenovo laptopsHui Wang2018-12-051-0/+20
| | | | | | | | | | | | | | | | | | | | | | | commit c4cfcf6f4297c9256b53790bacbbbd6901fef468 upstream. We have several Lenovo laptops with the codec alc285, when playing sound via headphone, we can hear click/pop noise in the headphone, if we let the headphone share the DAC of NID 0x2 with the speaker, the noise disappears. The Lenovo laptops here include P52, P72, X1 yoda2 and X1 carbon. I have tried to set preferred_dacs and override_conn, but neither of them worked. Thanks for Kailang, he told me to invalidate the NID 0x3 through override_wcaps.

* ALSA: hda/realtek - fix headset mic detection for MSI MS-B171Anisse Astier2018-12-051-0/+1
| | | | | | | | | | | | | | | | commit 8cd65271f8e545ddeed10ecc2e417936bdff168e upstream. MSI Cubi N 8GL (MS-B171) needs the same fixup as its older model, the MS-B120, in order for the headset mic to be properly detected. They both use a single 3-way jack for both mic and headset with an ALC283 codec, with the same pins used.

* ALSA: ac97: Fix incorrect bit shift at AC97-SPSA control writeTakashi Iwai2018-12-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | commit 7194eda1ba0872d917faf3b322540b4f57f11ba5 upstream. The function snd_ac97_put_spsa() gets the bit shift value from the associated private_value, but it extracts too much; the current code extracts 8 bit values in bits 8-15, but this is a combination of two nibbles (bits 8-11 and bits 12-15) for left and right shifts. Due to the incorrect bits extraction, the actual shift may go beyond the 32bit value, as spotted recently by UBSAN check: UBSAN: Undefined behaviour in sound/pci/ac97/ac97_codec.c:836:7 shift exponent 68 is too large for 32-bit type 'int' This patch fixes the shift value extraction by masking the properly with 0x0f instead of 0xff.

* ALSA: hda: Check the non-cached stream buffers more explicitlyTakashi Iwai2018-11-132-3/+9
| | | | | | | | | | | | | | | | | [ Upstream commit 78c9be61c3a5cd9e2439fd27a5ffad73a81958c7 ] Introduce a new flag, uc_buffer, to indicate that the controller requires the non-cached pages for stream buffers, either as a chip-specific requirement or specified via snoop=0 option. This improves the code-readability. Also, this patch fixes the incorrect behavior for C-Media chip where the stream buffers were never handled as non-cached due to the check of driver_type even if you pass snoop=0 option.

* ALSA: hda - Fix incorrect clearance of thinkpad_acpi hooksTakashi Iwai2018-11-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | commit 5e93a125f521efd00d71af31c2a301f3d46af48c upstream. Since the commit c647f806b8c2 ("ALSA: hda - Allow multiple ADCs for mic mute LED controls") we allow enabling the mic mute LED with multiple ADCs. The commit changed the function return value to be zero or a negative error, while this change was overlooked in the thinkpad_acpi helper code where it still expects a positive return value for success. This eventually leads to a NULL dereference on a system that has only a mic mute LED. This patch corrects the return value check in the corresponding code as well.

* ALSA: ca0106: Disable IZD on SB0570 DAC to fix audio popsAlex Stanoev2018-11-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit ac237c28d5ac1b241d58b1b7b4b9fa10efb22fb5 upstream. The Creative Audigy SE (SB0570) card currently exhibits an audible pop whenever playback is stopped or resumed, or during silent periods of an audio stream. Initialise the IZD bit to the 0 to eliminate these pops. The Infinite Zero Detection (IZD) feature on the DAC causes the output to be shunted to Vcap after 2048 samples of silence. This discharges the AC coupling capacitor through the output and causes the aforementioned pop/click noise. The behaviour of the IZD bit is described on page 15 of the WM8768GEDS datasheet: "With IZD=1, applying MUTE for 1024 consecutive input samples will cause all outputs to be connected directly to VCAP. This also happens if 2048 consecutive zero input samples are applied to all 6 channels, and IZD=0. It will be removed as soon as any channel receives a non-zero input". I believe the second sentence might be referring to IZD=1 instead of IZD=0 given the observed behaviour of the card. This change should make the DAC initialisation consistent with Creative's Windows driver, as this popping persists when initialising the card in Linux and soft rebooting into Windows, but is not present on a cold boot to Windows.

* ALSA: hda - Enable runtime PM only for discrete GPUTakashi Iwai2018-09-132-23/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent change of vga_switcheroo allowed the runtime PM for HD-audio on AMD GPUs, but this also resulted in a regression. When the HD-audio controller driver gets runtime-suspended, HD-audio link is turned off, and the hotplug notification is ignored. This leads to the inconsistent audio state (the connection isn't notified and ELD is ignored). The best fix would be to implement the proper ELD notification via the audio component, but it's still not ready. As a quick workaround, this patch adds the check of runtime_idle and allows the runtime suspend only when the vga_switcheroo is bound with discrete GPU. That is, a system with a single GPU and APU would be again without runtime PM to keep the HD-audio link for the hotplug notification and ELD read out. Also, the codec->auto_runtime_pm flag is set only for the discrete GPU at the time GPU gets bound via vga_switcheroo (i.e. only dGPU is forcibly runtime-PM enabled), so that APU can still get the ELD notification. For identifying which GPU is bound, a new vga_switcheroo client callback, gpu_bound, is implemented. The vga_switcheroo simply calls this when GPU is bound, and tells whether it's dGPU or APU.

* ALSA: hda - Fix cancel_work_sync() stall from jackpoll workTakashi Iwai2018-08-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | On AMD/ATI controllers, the HD-audio controller driver allows a bus reset upon the error recovery, and its procedure includes the cancellation of pending jack polling work as found in snd_hda_bus_codec_reset(). This works usually fine, but it becomes a problem when the reset happens from the jack poll work itself; then calling cancel_work_sync() from the work being processed tries to wait the finish endlessly. As a workaround, this patch adds the check of current_work() and applies the cancel_work_sync() only when it's not from the jackpoll_work. This doesn't fix the root cause of the reported error below, but at least, it eases the unexpected stall of the whole system.

|/ | | | | | | | | | | | | | | | | | | | | | | Commit c647f806b8c2 ("ALSA: hda - Allow multiple ADCs for mic mute LED controls") changed the return value of the snd_hda_gen_add_micmute_led() without actually updating the callers. Admittedly, almost no callers actually cared about the return value. But one call site very much did: the Dell wmi code. It would see the registration return zero, which _used_ to mean "failed" but now means "success", and clear the dell_micmute_led_set_func pointer. End result: the successful registration would end up calling the Dell code that thought it had all failed, and call through a NULL pointer. To make matters worse, it ends up being a tail-call, and with the retpoline sequence you don't even see the caller (dell_micmute_update()) in the stack trace, so the error ended up way less obvious than it should have been.

Notice that in this particular case, I replaced the code comment with a proper "fall through" annotation, which is what GCC is expecting to find. Signed-off-by: Gustavo A. R.

| * ALSA: hda/realtek - Add mute LED quirk for HP Spectre x360Alexandru Gagniuc2018-08-051-0/+1
| | | | | | | | | | | | | | | | | | | | This device has the same issues as the HP x360 wrt the MUTE LED and the front speakers not working. This patch fixes the MUTE LED issue, but doesn't touch the HDA verbs. The fix for the x360 does not work on the Spectre.

| * ALSA: pci: Remove empty init and exitTakashi Iwai2018-08-032-28/+0
| | | | | | | | | | | | | | | | | | | | | | | | For a sake of code simplification, remove the init and the exit entries that do nothing. Notes for readers: actually it's OK to remove *both* init and exit, but not OK to remove the exit entry. By removing only the exit while keeping init, the module becomes permanently loaded; i.e. you cannot unload it any longer! Signed-off-by: Takashi Iwai <tiwai@suse.de>

| * | ALSA: hda/hdmi: Use single mutex unlock in error pathsTakashi Iwai2018-07-291-34/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of calling mutex_unlock() at each error path multiple times, take the standard goto-and-a-single-unlock approach. This will simplify the code and make easier to find the unbalanced mutex locks. No functional changes, but only the code readability improvement as a preliminary work for further changes.

| * | ALSA: ctxfi: cthw20k2: Replace mdelay() with msleep() and usleep_range()Jia-Ju Bai2018-07-271-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hw_pll_init(), hw_dac_stop(), hw_dac_start() and hw_adc_init() are never called in atomic context. They call mdelay() to busily wait, which is not necessary. mdelay() can be replaced with msleep(). This is found by a static analysis tool named DCNS written by myself.
