Some of these, particularly the wm_adsp one in the immediate case, are needed as a basis for new work.
2024-03-28ASoC: rt-sdw*: add __func__ to all error logsPierre-Louis Bossart1-1/+1
The drivers for Realtek SoundWire codecs use similar logs, which is problematic to analyze problems reported by CI tools, e.g. "Failed to get private value: 752001 => 0000 ret=-5". It's not uncommon to have several Realtek devices on the same platform, having the same log thrown makes support difficult. This patch adds __func__ to all error logs which didn't already include it. No functionality change, only error logs are modified.

2023-08-07ASoC: rt711-sdca: enable pm_runtime in probe, keep status as 'suspended'Pierre-Louis Bossart1-2/+1
In stress cases involving module insertion/removal followed by playback/capture, it can happen that capture/playback is started before the codec enumeration completes. The codec driver registers its components with the ASoC framework during the probe stage, so there is currently no way for the card creation to wait for the codec enumeration/initialization to complete. In addition, when the capture/playback starts, the ASoC framework uses pm_runtime_get_sync() to properly refcount and power-manage devices. This is problematic in the SoundWire case because pm_runtime is enabled during the enumeration/initialization stage, so pm_runtime_get_sync() will return -EACCESS which is ignored. Additional errors will happen when setting the pm_runtime status as 'active' because the parent is not properly resumed, resulting in an error such as: "rt711 sdw:0:025d:0711:00: runtime PM trying to activate child device sdw:0:025d:0711:00 but parent (sdw-master-0) is not active" This patch suggests enabling pm_runtime during the probe, but marking the device as 'active' only after it is enumerated. That will force a dependency between the card and the codec, pm_runtime_get_sync() will have to wait for the codec device to resume and hence implicitly wait for the enumeration/initialization to be completed. In the nominal case where the codec device is already active the get_sync() would only perform a ref-count increase.

2021-06-21ASoC: rt711-sdca-sdw: fix race condition on system suspendPierre-Louis Bossart1-2/+44
In the initial driver we cancelled deferred work, but there is still a window of time where a new interrupt could result in new deferred work executed after the link is disabled, leading to an IO error. While we did not see this IO error on RT711-sdca-based platforms, the code pattern is similar to the RT700 case where the IO error was noted, so the fix is added for consistency. This patch uses an 'disable_irq_lock' mutex to prevent new interrupts from happening after the start of the system suspend. The choice of a mutex v. a spinlock is mainly due to the time required to clear interrupts, which requires a command to be transmitted by the SoundWire host IP and acknowledged with an interrupt. The 'interrupt_callback' routine is also not meant to be called from an interrupt context. An additional 'disable_irq' flag prevents race conditions where the status changes before the interrupts are disabled, but the workqueue handling status changes is scheduled after the completion of the system suspend. On resume the interrupts are re-enabled already by the io_init routine so we only clear the flag. The code is slightly different from the other codecs since the interrupt callback deals with the SDCA interrupts, leading to a much larger section that's protected by the mutex. The SoundWire interrupt scheme requires a read after clearing a status, it's not clear from the specifications what would happen if SDCA interrupts are disabled in the middle of the sequence, so the entire interrupt status read/write is kept as is, even if in the end we discard the information.

2021-06-08ASoC: rt711-sdca-sdw: use first_hw_init flag on resumePierre-Louis Bossart1-1/+1
The intent of the status check on resume was to verify if a SoundWire peripheral reported ATTACHED before waiting for the initialization to complete. This is required to avoid timeouts that will happen with 'ghost' devices that are exposed in the platform firmware but are not populated in hardware. Unfortunately we used 'hw_init' instead of 'first_hw_init'. Due to another error, the resume operation never timed out, but the volume settings were not properly restored.
