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.

ASoC: SOF: Compile and runtime IPC version selection

2022-06-14T10:22:12+00:00

The new IPC4 version is only supported by Intel platforms, iMX, AMD and MediaTek only uses the standard SOF IPC. There is no need for these platforms to build kernel support for IPC4 as it is just dead code for them. SND_SOC_SOF_IPC3 and SND_SOC_SOF_INTEL_IPC4 is introduced to allow compile time selection and exclusion of IPC implementations. To avoid randconfig failures add also support for runtime selection of the IPC ops in ipc.c based on sdev->pdata->ipc_type Signed-off-by: Peter Ujfalusi Reviewed-by: Bard Liao Reviewed-by: Ranjani Sridharan Link: https://lore.kernel.org/r/20220614075618.28605-1-peter.ujfalusi@linux.intel.com Signed-off-by: Mark Brown

Clone the existing code with prefix fixes as ipc3 fw_tracing implementation to be used when the core is converted to use generic ops for firmware tracing. Drop the dual licensing of the content as the implementation is based on debugfs.
