[PATCH v2 0/2] remoteproc: imx_dsp_rproc: Add coredump and recovery support

[PATCH v2 0/2] remoteproc: imx_dsp_rproc: Add coredump and recovery support

[Shengjiu Wang]

When recovery is triggered, rproc_stop() is called first then
rproc_start(), but there is no rproc_unprepare_device() and
rproc_prepare_device() in the flow. As the software reset is needed
before DSP starts, so move software reset from imx_dsp_runtime_resume()
to .load() to make the recovery work. And make sure memory is cleared
before loading firmware.

Add call rproc_coredump_set_elf_info() to initialize the elf info for
coredump, otherwise coredump will report error "ELF class is not set".

changes in v2:
- move .reset() from runtime resume to .load()
- IRAM and DRAM still in the coredump scope.

This is a much better approach.  During my last review I said that I would not
move forward with this work until Daniel or Iuliana provide their R-B and yet,
they have not been added to the recipient list.

I will have a look at this patchset at the beginning of next week.
I also plan to test it.

Thanks Mathieu, we will have a look at this asap.

We are part of imx@lists.linux.dev so we got the mail.

Hello Shengjiu,

Commit mostly looking good but the key point when writing a commit
is to explain why the commit is needed and less about what the
commit does (this should be obvious from the source code).


So, I would start with the context and that is:

Following commit: 6eed169c7fefd9cdbbccb5ba7a98470cc0c09c63
    remoteproc: imx_rproc: Enable attach recovery for i.MX8QM/QXP

enabled FW recovery, but is broken because <and here explain the reason that
you mostly described in the original commit>.

Then at the end add the Fixes tag.

Also, allow me on more day on Monday to test this patch.

Thanks,
Daniel.

[PATCH v2 2/2] remoteproc: imx_dsp_rproc: Add support of coredump

[Shengjiu Wang]

Add call rproc_coredump_set_elf_info() to initialize the elf info for
coredump, otherwise coredump will report error "ELF class is not set".
