2023-03-21ASoC: SOF: ipc4-control: Return on error in sof_ipc4_widget_kcontrol_setup()Peter Ujfalusi
The patch adding the bytes control support moved the error check outside of the list_for_each_entry() which was not correct as at the end of the list_for_each_entry() the scontrol will no longer point where the error happened, but it to the list head. Restore the original logic and return on the first error with the error code.

2023-03-14ASoC: SOF: ipc4: Add support for bytes controlMark Brown
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: This series will add support for bytes control and topology types. With IPC4 only the binary payload is sent to the firmware via LARGE_CONFIG message (which does similar multi-part message handling as the IPC3 control message did). The bytes payload itself is not checked by the kernel but user space expected to wrap it in sof_abi_hdr struct in order to get the target information of the binary data. The SOF firmware and sof-ctl have been updated to support blobs used in IPC4 setups.
2023-03-13ASoC: SOF: ipc4-control: Add support for bytes control get and putPeter Ujfalusi
Add support for bytes control by implementing bytes_get/put and bytes_ext_get/put and blobs with either module init instance or large config type. For module init instance type the put will only update the stored configuration blob and it is going to be taken into use next time the module is (re-)initialized. Large config type of blobs are sent to the firmware whenever the DSP is powered up.

2023-03-07ASoC: SOF: IPC4: update gain ipc msg definition to align with fwRander Wang
Recent firmware changes modified the curve duration from 32 to 64 bits, which breaks volume ramps. A simple solution would be to change the definition, but unfortunately the ASoC topology framework only supports up to 32 bit tokens. This patch suggests breaking the 64 bit value in low and high parts, with only the low-part extracted from topology and high-part only zeroes. Since the curve duration is represented in hundred of nanoseconds, we can still represent a 400s ramp, which is just fine. The defacto ABI change has no effect on existing users since the IPC4 firmware has not been released just yet.

2023-01-27ASoC: SOF: Protect swidget->use_count with mutex for kcontrol access racePeter Ujfalusi
The use_count of the swidget is protect by ALSA core PCM locking with the exception when an associated kcontrol is changed. It has been observed that a rightly timed kcontrol access during stream stop can result of an attempt to send a control update to a widget which has been freed up between the check of the use_count and the message sending. We need to protect the entire sof_widget_setup() and sof_widget_free() execution to make it safe to rely on the use_count. Move the code under an _unlocked() function and use a mutex to protect the execution of the functions for concurrency. On the control path we need to use the lock only for the kcontrol access, the widget_kcontrol_setup() op is called with the lock already held.
