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: Kconfig: Rename SND_SOC_SOF_INTEL_IPC4 to SND_SOC_SOF_IPC4

2023-09-19T12:49:07+00:00

ASoC: SOF: ipc4: add definition of telemetry slot for exception handling

2023-09-19T12:48:47+00:00

Core dump includes hardware platform information, cpu registers and
exception call stack. FW saves core dump to telemetry slot in shared
memory window for host in the event of FW exception. This patch creates
exception node in debugfs for user to dump telemetry data.

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
