2023-03-29ASoC: codecs: rt711-sdca: simplify set_streamPierre-Louis Bossart1-23/+7
Using a dynamic allocation to store a single pointer is not very efficient/useful. Worse, the memory is released in the SoundWire stream.c file, but still accessed in the DAI shutdown, leading to kmemleak reports. And last the API requires the previous stream information to be cleared when the argument is NULL. Simplify the code to address all 3 problems.

The initial settings will be written before the codec probe function. But, the rt711->component doesn't be assigned yet.

2022-06-07ASoC: codecs: rt700/rt711/rt711-sdca: resume bus/codec in .set_jack_detectPierre-Louis Bossart1-12/+14
The .set_jack_detect() codec component callback is invoked during card registration, which happens when the machine driver is probed. The issue is that this callback can race with the bus suspend/resume, and IO timeouts can happen. This can be reproduced very easily if the machine driver is 'blacklisted' and manually probed after the bus suspends. The bus and codec need to be re-initialized using pm_runtime helpers. Previous contributions tried to make sure accesses to the bus during the .set_jack_detect() component callback only happen when the bus is active. This was done by changing the regcache status on a component remove. This is however a layering violation, the regcache status should only be modified on device probe, suspend and resume. The component probe/remove should not modify how the device regcache is handled. This solution also didn't handle all the possible race conditions, and the RT700 headset codec was not handled. This patch tries to resume the codec device before handling the jack initializations. In case the codec has not yet been initialized, pm_runtime may not be enabled yet, so we don't squelch the -EACCES error code and only stop the jack information. When the codec reports as attached, the jack initialization will proceed as usual.

Realtek headset codec drivers typically check if the card is instantiated before proceeding with the jack detection.

The endianness flag is used on the CODEC side to specify an ambivalence to endian, typically because it is lost over the hardware link. This device receives audio over a SoundWire DAI and as such should have endianness applied.

2021-12-24ASoC/SoundWire: dai: expand 'stream' concept beyond SoundWirePierre-Louis Bossart1-1/+1
The HDAudio ASoC support relies on the set_tdm_slots() helper to store the HDaudio stream tag in the tx_mask. This only works because of the pre-existing order in soc-pcm.c, where the hw_params() is handled for codec_dais *before* cpu_dais. When the order is reversed, the stream_tag is used as a mask in the codec fixup functions: /* fixup params based on TDM slot masks */ if (substream->stream == SNDRV_PCM_STREAM_PLAYBACK && codec_dai->tx_mask) soc_pcm_codec_params_fixup(&codec_params, codec_dai->tx_mask); As a result of this confusion, the codec_params_fixup() ends-up generating bad channel masks, depending on what stream_tag was allocated. We could add a flag to state that the tx_mask is really not a mask, but it would be quite ugly to persist in overloading concepts. Instead, this patch suggests a more generic get/set 'stream' API based on the existing model for SoundWire. We can expand the concept to store 'stream' opaque information that is specific to different DAI types. In the case of HDAudio DAIs, we only need to store a stream tag as an unsigned char pointer. The TDM rx_ and tx_masks should really only be used to store masks. Rename get_sdw_stream/set_sdw_stream callbacks and helpers as get_stream/set_stream. No functionality change beyond the rename.

2021-06-21ASoC: rt711-sdca-sdw: fix race condition on system suspendPierre-Louis Bossart1-0/+4
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.
