| * ALSA: hda: Fix position reporting on PoulsboTakashi Iwai2022-10-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hans reported that his Sony VAIO VPX11S1E showed the broken sound behavior at the start of the stream for a couple of seconds, and it turned out that the position_fix=1 option fixes the issue. It implies that the position reporting is inaccurate, and very likely hitting on all Poulsbo devices. The patch applies the workaround for Poulsbo generically to switch to LPIB mode instead of the default position buffer.

| * ALSA: hda/hdmi: Don't skip notification handling during PM operationTakashi Iwai2022-10-011-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The HDMI driver skips the notification handling from the graphics driver when the codec driver is being in the PM operation. This behavior was introduced by the commit eb399d3c99d8 ("ALSA: hda - Skip ELD notification during PM process"). This skip may cause a problem, as we may miss the ELD update when the connection/disconnection happens right at the runtime-PM operation of the audio codec. Although this workaround was valid at that time, it's no longer true; the fix was required just because the ELD update procedure needed to wake up the audio codec, which had lead to a runtime-resume during a runtime-suspend. Meanwhile, the ELD update procedure doesn't need a codec wake up any longer since the commit 788d441a164c ("ALSA: hda - Use component ops for i915 HDMI/DP audio jack handling"); i.e. there is no much reason for skipping the notification. Let's drop those checks for addressing the missing notification.

| * ALSA: usb-audio: Fix potential memory leaksTakashi Iwai2022-09-301-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the driver hits -ENOMEM at allocating a URB or a buffer, it aborts and goes to the error path that releases the all previously allocated resources. However, when -ENOMEM hits at the middle of the sync EP URB allocation loop, the partially allocated URBs might be left without released, because ep->nurbs is still zero at that point. Fix it by setting ep->nurbs at first, so that the error handler loops over the full URB list.

| * ALSA: hda/realtek: More robust component matching for CS35L41Takashi Iwai2022-09-301-25/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the previous commit implies, a system may have a different SPI bus number that is embedded in the device string. And, assuming the fixed bus number is rather fragile; it may be assigned differently depending on the configuration or on the boot environment. Once when a bus number change happens, the binding fails, resulting in the silence. This patch tries to make the matching a bit more relaxed, allowing to bind with a different bus number (or without it). So the previous fix, the introduction of ALC245_FIXUP_CS35L41_SPI1_2 fixup became superfluous, and this is unified to ALC245_FIXUP_CS35L41_SPI_2.

| * ALSA: pcm: Avoid reference to status->stateTakashi Iwai2022-09-275-98/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the PCM core and driver code, there are lots place referring to the current PCM state via runtime->status->state. This patch introduced a local PCM state in runtime itself and replaces those references with runtime->state. It has improvements in two aspects: - The reduction of a indirect access leads to more code optimization - It avoids a possible (unexpected) modification of the state via mmap of the status record The status->state is updated together with runtime->state, so that user-space can still read the current state via mmap like before, too. This patch touches only the ALSA core code. The changes in each driver will follow in later patches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use __GFP_RETRY_MAYFAIL instead of __GFP__NORETRY in snd_dma_dev_alloc(), snd_dma_wc_alloc() and friends, to allocate pages for device memory. The MAYFAIL flag retains the semantics of not triggering the OOM killer, but lowers the risk of alloc failure. MAYFAIL flag was added in commit dcda9b04713c3 ("mm, tree wide: replace __GFP_REPEAT by __GFP_RETRY_MAYFAIL with more useful semantic"). This change addresses recurring failures with SOF audio driver in test cases where a system suspend-resume stress test is run, combined with an active high memory-load use-case. The failure typically shows up as: [ 379.480229] sof-audio-pci-intel-tgl 0000:00:1f.3: booting DSP firmware [ 379.484803] sof-audio-pci-intel-tgl 0000:00:1f.3: error: memory alloc failed: -12 [ 379.484810] sof-audio-pci-intel-tgl 0000:00:1f.3: error: dma prepare for ICCMAX stream failed Multiple fixes to reduce the memory usage of DSP boot have been identified in SOF driver, but even with those fixes, debug on affected systems has shown that even a single page alloc may fail with __GFP_NORETRY. When this occurs, system is under significant load on physical memory, but a lot of reclaimable pages are available, so the system has not run out of memory. With __GFP_RETRY_MAYFAIL, the errors are not hit in these stress tests. The alloc failure is severe as audio capability is completely lost if alloc failure is hit at system resume. An alternative solution was considered where the resources for DSP boot would be kept allocated until driver is unbound. This would avoid the allocation failure, but consume memory that is only needed temporarily at probe and resume time. It seems better to not hang on to the memory, but rather work a bit harder for allocating the pages at resume.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per discussion on the alsa-devel mailing list [1], the legacy PIN to PCM device mapping is obsolete nowadays. The maximum number of the simultaneously usable PCM devices is equal to the HDMI codec converters. Remove the extra PCM devices (beyond the detected converters) and force the use of the dynamic PCM device allocation. The legacy code is removed. I believe that all HDMI codecs have the jack sensing feature. Move the check to the codec probe function and print a warning, if a codec without this feature is detected.

| * | ALSA: usb-audio: Split endpoint setups for hw_params and prepare (take#2)Takashi Iwai2022-09-203-63/+70

The details taken from the v1 patch: One of the former changes for the endpoint management was the more consistent setup of endpoints at hw_params. snd_usb_endpoint_configure() is a single function that does the full setup, and it's called from both PCM hw_params and prepare callbacks. Although the EP setup at the prepare phase is usually skipped (by checking need_setup flag), it may be still effective in some cases like suspend/resume that requires the interface setup again. As it's a full and single setup, the invocation of snd_usb_endpoint_configure() includes not only the USB interface setup but also the buffer release and allocation. OTOH, doing the buffer release and re-allocation at PCM prepare phase is rather superfluous, and better to be done only in the hw_params phase. For those optimizations, this patch splits the endpoint setup to two phases: snd_usb_endpoint_set_params() and snd_usb_endpoint_prepare(), to be called from hw_params and from prepare, respectively. Note that this patch changes the driver operation slightly, effectively moving the USB interface setup again to PCM prepare stage instead of hw_params stage, while the buffer allocation and such initializations are still done at hw_params stage. And, the change of the USB interface setup timing (moving to prepare) gave an interesting "fix", too: it was reported that the recent kernels caused silent output at the beginning on playbacks on some devices on Android, and this change casually fixed the regression. It seems that those devices are picky about the sample rate change (or the interface change?), and don't follow the too immediate rate changes. Meanwhile, Android operates the PCM in the following order: - open, then hw_params with the possibly highest sample rate - close without prepare - re-open, hw_params with the normal sample rate - prepare, and start streaming This procedure ended up the hw_params twice with different rates, and because the recent kernel did set up the sample rate twice one and after, it screwed up the device. OTOH, the earlier kernels didn't set up the USB interface at hw_params, hence this problem didn't appear. Now, with this patch, the USB interface setup is again back to the prepare phase, and it works around the problem automagically. Although we should address the sample rate problem in a more solid way in future, let's keep things working as before for now. *** What's new in the take#2 patch: - The regression caused by the v1 patch (bko#216500) was due to the missing check of need_setup flag at hw_params. Now the check is added, and the snd_usb_endpoint_set_params() call is skipped when the running EP is re-opened. - There was another bug in v1 where the clock reference rate wasn't updated at hw_params phase, which may lead to a lack of the proper hw constraints when an application doesn't issue the prepare but only the hw_params call.

Fix by exposing a locked version of snd_hdac_stream_release() and use it without releasing the spinlock.

It assumed that the probe callback gets called for those later interfaces, but it's not always true; as the driver loops over the descriptor and probes the matching ones, it's not separately called via multiple probe calls. This results in the missing card registration, i.e. no sound device. For addressing this problem, replace the check whether the last interface is processed with usb_interface_claimed() instead of the comparison with the probe interface number.
