It also turns Tegra DRM HDMI driver into HDMI audio CODEC provider. Finally, HDMI audio is enabled in device-trees. For now the audio is enable only for Acer A500 tablet and Toshiba AC100 netbook because they're already supported by upstream, later on ASUS TF101 tablet will join them. I based S/PDIF patches on Arnd's Bergmann patch from a separate series [1] that removes obsolete slave_id. This eases merging of the patches by removing the merge conflict. This is a note for Mark Brown. I also based this series on top of power management series [2]. I.e. [2] should be applied first, otherwise "Add S/PDIF node to Tegra20 device-tree" patch should have merge conflict. This is a note for Thierry. [1] https://patchwork.ozlabs.org/project/linux-tegra/list/?series=273312 [2] https://patchwork.ozlabs.org/project/linux-tegra/list/?series=274534 Changelog: v4: - Added patches that update multi_v7_defconfig with the enabled S/PDIF and APB DMA drivers. v3: - Renamed S/PDIF device-tree clocks as was suggested by Rob Herring. - Added r-bs and acks that were given by Rob Herring to v2. v2: - Corrected I2S yaml problem that was reported by the DT bot for v1 by removing the non-existent required clock-names property. - Removed assigned-clocks property from S/PDIF yaml since this property is now inherited from the clocks property. - Reordered the "tegra20: spdif: Set FIFO trigger level" patch, making it the first sound/soc patch in the series, like it was suggested by Mark Brown in the comment to v1. Also reworded commit message of this patch to *not* make it looks like it should be backported to stable kernels.

This allows to play audio over S/PDIF and I2S simultaneously. The root of the problem is that audio components on Tegra share the same audio PLL, and thus, only a subset of rates can be supported if we want to play audio simultaneously. Filter out audio rates that don't match parent clock rate if device-tree has the nvidia,fixed-parent-rate property.

This creates problem for HDMI audio because it uses SPDIF and audio may not work if SPDIF's clock doesn't exactly match standard audio rate since some receivers may reject audio in that case. Filter out audio rates which SPDIF output can't support, assuming that other components won't change rate at runtime.

The typical use-case would be music playback over a headset: this additional PCM device provides more buffering and longer latencies, leaving the rest of the system sleep for longer periods. Notifications and 'regular' low-latency audio playback would still use the 'normal' PCM device and be mixed with the 'deep buffer' before rendering on the headphone endpoint. The tentative direction would be to expose this alternate device to PulseAudio/PipeWire/CRAS via the UCM SectionModifier definitions. That seemed a straightforward topology change until our automated validation stress tests started reporting issues on SoundWire platforms, when e.g. two START triggers might be send and conversely the STOP trigger is never sent. The SoundWire stream state management flagged inconsistent states when the two 'normal' and 'deep buffer' devices are used concurrently with rapid play/stop/pause monkey testing. Looking at the soc-pcm.c code, it seems that the BE state management needs a lot of love. a) there is no consistent protection for the BE state. In some parts of the code, the state updates are protected by a spinlock but in the trigger they are not. When we open/play/close the two PCM devices in stress tests, we end-up testing a state that is being modified. That can't be good. b) there is a conceptual deadlock: on stop we check the FE states to see if a shared BE can be stopped, but since we trigger the BE first the FE states have not been modified yet, so the TRIGGER_STOP is never sent. This patchset suggests the removal of the dedicated 'dpcm_lock' and follows the design suggested by Takashi Iwai. By default the protection relies on the 'pcm_mutex', except for the FE and BE triggers where the mutex cannot be used. In this case, the FE PCM lock is used instead. In the cases where a BE is added/removed, the pcm_mutex and FE PCM lock are both taken. In addition, the BE PCM lock is used to serialize access to a shared BE. With these patches I am able to run our entire validation suite without any issues with this new 'deep buffer' topology, and no regressions on existing solutions [1]. The tests were reproduced by Bard Liao for SoundWire devices. One might ask 'how come we didn't see this earlier'? The answer is probably that the .trigger callbacks in most implementations seems to perform DAPM operations, and sending the triggers multiple times is not an issue. In the case of SoundWire, we do use the .trigger callback to reconfigure the bus using the 'bank switch' mechanism. It could be acceptable to tolerate a trigger multiple times, but the deadlock on stop cannot be fixed at the SoundWire level alone. Opens: 1) The issues reported by Nvidia on the RFCv3 may or may not be present. We'd need test results to make sure the locking update does not introduce a regression on Tegra. 2) There are other reports of kernel oopses [2] that seem related to the lack of protection. I'd be good to confirm if this patchset solve these problems as well. [1] https://github.com/thesofproject/linux/pull/3146 [2] https://lore.kernel.org/alsa-devel/002f01d7b4f5$c030f4a0$4092dde0$@samsung.com/ changes since RFCv3: Used two patches from Takashi. We now use the pcm_mutex, the FE stream lock when adding and deleting a BE, and the BE stream lock to handle concurrency between streams using the same BE. Added a patch to use GFP_ATOMIC for the DPCM structure. Fixed PAUSE_RELEASE transition (GitHub comment from Kai Vehmanen) changes since RFCv2: Removal of dpcm_lock to use FE PCM locks (credits to Takashi Iwai for the suggestion). The FE PCM lock is now used before each use of for_each_dpcm_be() - with the exception of the trigger where the lock is already taken. This change is also applied in drivers which make use of this loop (compress, SH, FSL). Addition of BE PCM lock to deal with mutual exclusion between triggers for the same BE. Alignment of the BE atomicity on the FE on connections, this is required to avoid sleeping in atomic context.

Extend the allowed states to restart the BE when PAUSE_RELEASE is received, and increase the refcount if the BE is already in START. [1] the existing logic does not move the BE state back to PAUSED when the FE2 is stopped. This patch does not change the logic; it would be painful to keep a history of changes on the FE side, the state machine is already rather complicated with transitions based on the last BE state and the trigger type.

| | | * | | ASoC: soc-pcm: test refcount before triggeringPierre-Louis Bossart2021-12-141-11/+42

This is not desirable, we only want to trigger a BE once, which is straightforward to implement with a refcount. For stop/pause/suspend, the problem is more complicated: the check implemented in snd_soc_dpcm_can_be_free_stop() may fail due to a conceptual deadlock when we trigger the BE before the FE. In this case, the FE states have not yet changed, so there are corner cases where the TRIGGER_STOP is never sent - the dual case of start where multiple triggers might be sent. This patch suggests an unconditional trigger in all cases, without checking the FE states, using a refcount protected by the BE PCM stream lock.

This race condition is problematic in the case of SoundWire BE dailinks, and this is not desirable in a general case. This patch relies on the existing BE PCM lock, which takes atomicity into account. The locking model assumes that all interactions start with the FE, so that there is no deadlock between FE and BE locks.

The use of irqsave/irqrestore was also overkill. The suggested model is: 1) The pcm_mutex is the top-most protection of BE links in the FE. The pcm_mutex is applied always on either the top PCM callbacks or the external call from DAPM, not taken in the internal functions. 2) the FE stream lock is taken in higher levels before invoking dpcm_be_dai_trigger() 3) when adding and deleting a BE, both the pcm_mutex and FE stream lock are taken.

If the FE is nonatomic, this patch forces the BE to be nonatomic as well. That should have no negative impact since the BE 'inherits' the FE properties. However, if the FE is atomic and the BE is not, then the configuration is flagged as invalid.

This is necessary to support certain functionality such as voice call audio. See PATCH 4/5 for details. Also, qcom,apq8016-sbc.txt is converted to DT schema by adding it to the existing qcom,sm8250.yaml. The bindings are similar enough that it is easier to share a single schema instead of duplicating everything into multiple ones.
