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 dcda9b04 ("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Per discussion on the alsa-devel mailing list [1], the legacy PIN to PCM device mapping is obsolete nowadays.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.

We fixed the bug introduced by the patch for managing the shared clocks at the commit 809f44a0 ("ALSA: usb-audio: Clear fixed clock rate at closing EP"), but it was merely a workaround. By this change, the clock reference rate is cleared at each EP close, hence the still remaining EP may need a re-setup of rate unnecessarily. This patch introduces the proper refcounting for the clock reference object so that the clock setup is done only when needed.

This is a second attempt to fix the bug appearing on Android with the recent kernel; the first try was ff878b40 and reverted at commit 79764ec7. 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. This patch fixes it as well by tracking the clock rate change in the prepare callback with a new flag "need_update" for the clock reference object, just like others. - The configure_endpoints() are simplified and folded back into snd_usb_pcm_prepare().

The snd_hdac_ext_stream_release() routine uses the bus reg_lock, but releases it before calling snd_hdac_stream_release() where the bus reg_lock is taken again. This creates a timing window where the link stream release could test an invalid 'opened' boolean status and fail to recouple the host and link parts. Fix by exposing a locked version of snd_hdac_stream_release() and use it without releasing the spinlock.

The logic is needlessly complicated, the basic rule is: The host streams can be found by checking the 'opened' boolean. The link streams can be found by checking the 'link_locked' boolean. Once a stream is found, it can be unconditionally decoupled. The snd_hdac_ext_stream_decouple_locked() routine will make sure the register status is modified as needed and the 'decoupled' boolean set.

During the code change to add the support for devres-managed card instance, we put an explicit kfree(card) call at the error path in snd_card_new(). This is needed for the early error path before the card is initialized with the device, but is rather superfluous and causes a double-free at the error path after the card instance is initialized, as the destructor of the card object already contains a kfree() call. This patch fixes the double-free situation by removing the superfluous kfree(). Meanwhile we need to call kfree() explicitly for the early error path, so it's added there instead.

The recent fix in commit 6392dcd1 ("ALSA: usb-audio: Register card at the last interface") tried to delay the card registration until the last found interface is probed. 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.
