It allows to prevent conflicts between audio components that share same parent PLL. For instance, this property allows to have HDMI audio, speaker and headphones in the system playing audio simultaneously, which is a common pattern for consumer devices. Reviewed-by:

All references to the slave_id field have been removed, so remove the field as well to prevent new references from creeping in again. Originally this allowed slave DMA drivers to configure which device is accessed with the dmaengine_slave_config() call, but this was inconsistent, as the same information is also passed while requesting a channel, and never changes in practice. In modern kernels, the device is always selected when requesting the channel, so the .slave_id field is no longer useful. Reviewed-by:

The display driver wants to pass a custom flag to the DMA engine driver, which it started doing by using the slave_id field that was traditionally used for a different purpose. As there is no longer a correct use for the slave_id field, it should really be removed, and the remaining users changed over to something different. The new mechanism for passing nonstandard settings is using the .peripheral_config field, so use that to pass a newly defined structure here, making it clear that this will not work in portable drivers.

The slave_id was previously used to pick one DMA slave instead of another, but this is now done through the DMA descriptors in device tree. For the qcom_adm driver, the configuration is documented in the DT binding to contain a tuple of device identifier and a "crci" field, but the implementation ends up using only a single cell for identifying the slave, with the crci getting passed in nonstandard properties of the device, and passed through the dma driver using the old slave_id field. Part of the problem apparently is that the nand driver ends up using only a single DMA request ID, but requires distinct values for "crci" depending on the type of transfer. Change both the dmaengine driver and the two slave drivers to allow the documented binding to work in addition to the ad-hoc passing of crci values. In order to no longer abuse the slave_id field, pass the data using the "peripheral_config" mechanism instead. Signed-off-by:

It appears that the code that reads the slave_id from the channel config was copied incorrectly from other drivers. Nothing ever sets this field on platforms that use this driver, so remove the reference. Reviewed-by:

Arnd Bergmann authored
The DMA resource is never set up anywhere, and passing this as slave_id has not been the proper procedure in a long time. As a preparation for removing all slave_id references from the ALSA code, remove this one. According to Dmitry Osipenko, this driver has never been used and the mechanism for configuring DMA would not work as it is implemented, so this part will get rewritten when the driver gets put into use again in the future.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>: We've been adding a 'deep buffer' PCM device to several SOF topologies in order to reduce power consumption. 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.

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.

A BE connected to more than one FE, e.g. in a mixer case, can go through the following transitions. play FE1 -> BE state is START pause FE1 -> BE state is PAUSED play FE2 -> BE state is START stop FE2 -> BE state is STOP (see note [1] below) release FE1 -> BE state is START stop FE1 -> BE state is STOP play FE1 -> BE state is START pause FE1 -> BE state is PAUSED play FE2 -> BE state is START release FE1 -> BE state is START stop FE2 -> BE state is START stop FE1 -> BE state is STOP play FE1 -> BE state is START play FE2 -> BE state is START (no change) pause FE1 -> BE state is START (no change) pause FE2 -> BE state is PAUSED release FE1 -> BE state is START release FE2 -> BE state is START (no change) stop FE1 -> BE state is START (no change) stop FE2 -> BE state is STOP The existing code for PAUSE_RELEASE only allows for the case where the BE is paused, which clearly would not work in the sequences above. 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.

On start/pause_release/resume, when more than one FE is connected to the same BE, it's possible that the trigger is sent more than once. 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. Signed-off-by:

When more than one FE is connected to a BE, e.g. in a mixing use case, the BE can be triggered multiple times when the FE are opened/started concurrently. 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. Signed-off-by:

The existing locking for DPCM has several issues a) a confusing mix of card->mutex and card->pcm_mutex. b) a dpcm_lock spinlock added inconsistently and on paths that could be recursively taken. 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.

Since the flow for DPCM is based on taking a lock for the FE first, we need to make sure during the connection between a BE and an FE that they both use the same 'atomicity', otherwise we may sleep in atomic context. 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. Signed-off-by:
