2022-12-07ASoC: Intel: Skylake: Topology and shutdown fixesMark Brown4-62/+44
Merge series from Cezary Rojewski <[email protected]>: Even though skylake-driver is going to be replaced by the avs-driver, the goal is to keep it functional on all the configurations it supports until its EOL. When comparing chrome trees against upstream skylake-driver, couple fixes pop up that are not part of upstream repository. These fixes are backed up by real bugs (issue trackers), address real problems. There is no reason for them to stay in the internal tree. Patches 1-4 combined together address issue where the driver updates the presumably static audio format descriptions coming from the topology files through its "fixup" functions. As long as given audio format is used by a single path, nothing collides and any updates are harmless. However, when multiple paths e.g.: DMIC and HDMI1 utilize the same audio format descriptor, any updates caused by the opening of the first path, may cause the second to fail. The 5th change from the set fixes driver hang sporadically occurring during shutdown procedure. Once HDAudio links are powered down along with the AudioDSP, the hang stops reproducing. The last change helps survive in environments with limited/fragmented memory. While the BDL is small already, other buffers can be allocated using scatter-gather. This basically aligns the code with what the avs-driver does.

2022-12-05ASoC: Intel: avs: Data probing and fw loggingMark Brown22-100/+1172
Merge series from Cezary Rojewski <[email protected]>: The patchset focuses on debug functionality for the avs-driver. Two major blocks are covered here: data probing and AudioDSP firmware logging. Both are configured and controlled through debugfs. Data probing is a AudioDSP debug functionality which allows for gathering the actual data that is being routed to or from a module. Helps in debugging its processing capabilities - navigate to a specific module which may have caused a glitch within a pipeline (set of modules bound together). First few allow for assigning compress stream to a HDAudio stream, what is currently limited to pcm substreams only. These patches were already present on this list and reviewed in the past [1]. The next few tidy existing debug-related code up so it's ready for addition of new functionalities and make it clear which part of the avs is debug related and which is not. These also simplify the existing locking around the trace fifo. Afterward, debug-related IPCs are defined along with stub soc-component and compress DAI operations. Not much is done there as it's not a standard PCM streaming scenario. Most code found in compress operations is inherited from the HOST side of HDAudio streaming found in pcm.c file of the driver. Finally, a debugfs file operations are defined. These facilitate connecting to DSP modules from which the data shall be gathered as well as control and configuration of firmware logging. Additionally, entries are added to allow for dumping snapshots of key memory windows.
2022-12-05ASoC: sof_es8336: fix possible use-after-free in sof_es8336_remove()Yang Yingliang1-1/+1
sof_es8336_remove() calls cancel_delayed_work(). However, that function does not wait until the work function finishes. This means that the callback function may still be running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling cancel_delayed_work_sync(), which ensures that the work is properly cancelled, no longer running, and unable to re-schedule itself.

2022-12-04ASoC/tda998x: Fix reporting of nonexistent capture streamsMark Brown298-1064/+2171
Merge series from Mark Brown <[email protected]>: The recently added pcm-test selftest has pointed out that systems with the tda998x driver end up advertising that they support capture when in reality as far as I can see the tda998x devices are transmit only. The DAIs registered through hdmi-codec are bidirectional, meaning that for I2S systems when combined with a typical bidrectional CPU DAI the overall capability of the PCM is bidirectional. In most cases the I2S links will clock OK but no useful audio will be returned which isn't so bad but we should still not advertise the useless capability, and some systems may notice problems for example due to pinmux management. This is happening due to the hdmi-codec helpers not providing any mechanism for indicating unidirectional audio so add one and use it in the tda998x driver. It is likely other hdmi-codec users are also affected but I don't have those systems to hand.

Currently the hdmi-codec driver always registers both playback and capture capabilities but for most systems there's no actual capture capability, usually HDMI is transmit only. Provide platform data which allows the users to indicate what is supported so that we don't end up advertising things to userspace that we can't actually support. In order to avoid breaking existing users the flags in platform data are a bit awkward and specify what should be disabled rather than doing the perhaps more expected thing and defaulting to not supporting capture.

2022-12-01ASoC: da7219: Fix pole orientation detection on OMTP headsets when playing musicDavid Rau2-6/+37
The OMTP pin define headsets can be mis-detected as line out instead of OMTP, causing obvious issues with audio quality. This patch is to put increased resistances within the device at a suitable point. To solve this issue better, the new mechanism setup ground switches with conditional delay control and these allow for more stabile detection process to operate as intended. This conditional delay control will not impact the hardware process but use extra system resource. This commit improves control of ground switches in the AAD logic.
