2025-05-29ASoC: SOF: ipc4-control: Use SOF_CTRL_CMD_BINARY as numid for bytes_extPeter Ujfalusi
commit 4d14b1069e9e672dbe1adab52594076da6f4a62d upstream. The header.numid is set to scontrol->comp_id in bytes_ext_get and it is ignored during bytes_ext_put. The use of comp_id is not quite great as it is kernel internal identification number. Set the header.numid to SOF_CTRL_CMD_BINARY during get and validate the numid during put to provide consistent and compatible identification number as IPC3. For IPC4 existing tooling also ignored the numid but with the use of SOF_CTRL_CMD_BINARY the different handling of the blobs can be dropped, providing better user experience.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v6.8 This is a relatively quiet release, there's a lot of driver specific changes and the usual high level of activity in the SOF core but the one big core change was Mormioto-san's work to support more N:M CPU:CODEC mapping cases. Highlights include: - Enhanced support for N:M CPU:CODEC mappings in the core and in audio-graph-card2. - Support for falling back to older SOF IPC versions where firmware for new versions is not available. - Support for notification of control changes generated by SOF firmware with IPC4. - Device tree support for describing parts of the card which can be active over suspend (for very low power playback or wake word use cases). - ACPI parsing support for the ES83xx driver, reducing the number of quirks neede for x86 systems. - Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm SM8250, SM8550, SM8650 and X1E80100. - Removal of Freescale MPC8610 support, the SoC is no longer supported by Linux.
2023-12-01ASoC: SOF: ipc4-topology: Correct data structures for the GAIN modulePeter Ujfalusi
Move the base_cfg to struct sof_ipc4_gain_data. This struct describes the message payload passed to the firmware via the mailbox. It is not wise to be 'clever' and try to use the first part of a struct as IPC message without marking the message section as packed and aligned.

Implement the sof_ipc_tplg_control_ops.update function to support a control change notification from the firmware on switch or enum control types. Based on the module notification message content, look up the swidget, then the scontrol which was the source of the notification then if the message contains the changed values update the cached values. If only a notification without values received, marked the control as dirty and on next read access fetch the new values from the firmware.

2023-05-23ASoC: sof: Improve sof_ipc4_bytes_ext_put functionPaul Olaru
The function is improved in the way that if the firmware returns a validation error on the newly sent bytes, then the kernel will automatically restore to the old bytes value for a given kcontrol. This way, if the firmware rejects a data blob then the kernel will also reject it, instead of saving it for the next suspend/resume cycle. The old behaviour is that the kernel would save it anyway and on next firmware boot it would apply the previously-rejected configuration, leading to errors during playback. Additionally, the function also saves previously validated configurations, so that if the firmware does end up rejecting a new bytes value the kernel can send an old, previously-valid configuration.

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.
