ASoC: SOF: ipc4: Ensure DSP is in D0I0 during sof_ipc4_set_get_data()

2023-04-13T14:55:18+00:00

[ Upstream commit e51f49512d98783b90799c9cc2002895ec3aa0eb ] The set_get_data() IPC op bypasses the check for the no_pm flag as done with the regular IPC tx_msg op. Since set_get_data should be performed when the DSP is in D0I0, set the DSP power state to D0I0 before sending the IPC's in sof_ipc4_set_get_data().

It can help debugging IPC timeout issues (like we do with IPC3) if we dump the IPC and DSP information.

ASoC: SOF: ipc4: Add support for mtrace log extraction

2022-09-09T17:48:48+00:00

One of the debugging/logging features for an IPC4 based firmware is the use of the debug window to deliver log messages to host via the shared SRAM. The initial implementation of the mtrace supports only TGL/MTL style of logging, but can be extended to support other types, like APL, SKL, CNL, etc. The window is split into 16 'slots' where the first slot contains the descriptors for the remaining 15 slots. Each DSP core logs to a separate slot and the slot allocation is not fixed, we can not assume that the first slot is always used by core0 for example. The firmware sends LOG_BUFFER_STATUS message when new log batch is available from one of the cores (after it updated the write_ptr in the given slot). Host should update the read_ptr in the same slot when it has taken out log data. The patch also updates the sof_ipc4_fw_data struct with parameters needed for the mtrace to be enabled and used safely.
