ASoC: SOF: IPC4: query fw_context_save feature from fw

2023-12-15T12:57:56+00:00

Driver queries fw_context_save feature when fw is ready and can skip library reload with this feature since library is saved in persistent memory. The default value of fw_context_save is true unless fw reports false.

ASoC: SOF: Intel: Do not use resource managed allocation for ipc4_data

2023-11-29T13:25:14+00:00

Manage the ipc4_data allocation in code instead of devm since the ops_init might be called more than once due to IPC type fallback.

ASoC: SOF: ipc4/Intel: Support for firmware exception

2023-09-19T17:22:11+00:00

Merge series from Peter Ujfalusi : When a firmware crashes it creats a panic information into a telemetry slot. The panic format is defined by Zephyr, includes stack and additional information to help to identify the reason for the crash. Part of the firmware exception handling the firmware also sends an EXCEPTION_CAUGHT notification. This series implements the kernel side handling of the exception: print information into the kernel log export the whole telemetry slot to user space for tools extract additional information from the panic dump.

ASoC: SOF: Intel: Use generic names for IPC types

2023-09-19T12:49:11+00:00

Use the new SOF_IPC_TYPE_3, SOF_IPC_TYPE_4 in core code. No functional changes, just renaming.

Get the FW panic information from telemetry data in memory window and dump it to kernel log. The old platforms before CAVS 2.5+ don't support it since there is no support in FW for them.

ASoC: SOF: Intel: tgl: unify core_put on IPC3 & IPC4 path

2023-05-23T12:56:00+00:00

Firmware may do context saving before powering off primary core, so driver needs to send ipc msg by set_core_state. In IPC4 path, firmware needs to save current context to IMR before powering off primary core. Firmware does nothing for set_core_state message in IPC3 path. So IPC4 and IPC3 can share the same operation sequence.

ASoC: SOF: Intel: Split the set_power_op for IPC3 and IPC4

2023-04-20T11:52:02+00:00

Suspending to S0iX with IPC3 requires the PM_GATE IPC to be sent again to stop the DMA trace. But with IPC4, this is not needed as the trace is stopped with the LARGE_CONFIG_SET IPC. Also, sending the MOD_D0IX IPC to set the D0I3 state again when the DSP is in D0I3 already results in an imbalance in PM runtime states in the firmware. So split the set_power_state ops for IPC3 and IPC4 to avoid sending the MOD_D0IX IPC when the DSP is already in D0I3 with IPC4.

ASoC: SOF: Intel: pci-tgl: unblock S5 entry if DMA stop has failed"

2022-12-12T15:44:20+00:00

If system shutdown has not been completed cleanly, it is possible the DMA stream shutdown has not been done, or was not clean. If this is the case, Intel TGL/ADL HDA platforms may fail to shutdown cleanly due to pending HDA DMA transactions. To avoid this, detect this scenario in the shutdown callback, and perform an additional controller reset. This has been tested to unblock S5 entry if this condition is hit.
