I'm with Mani, we should try to fix ath10k instead. Hopefully we can
find a fix soon.
Hi Team,
Any updates on this? I can reproduce this hard crash on v5.9-rc1 as
well.
It is not a blocker for us because we switched to a userspace
workaround, where we do not wait for modem to shutdown gracefully and
SIGKILL it instead, during the shutdown/reboot process. But I'm happy
to take a swing at any intermediate/in-progress solution available.
Govind submitted this patch and later he asked to drop it, but I think
it would be a good idea to test it anyway:
ath10k: Move msa region map/unmap to init/deinit path
https://lkml.kernel.org/r/[email protected]
(patchwork is down so I cannot give a patchwork link)
This patchwork is not fixing the issue and changing MSA mapping sequence
is major design change.
This issue is only seen with DB845 which uses SCM call, newer targets
QCS404/SC7180/SM8150 will not have this issue as MSA mapping is
hard-coded in TZ.
Probably changes in qmi layer to give different indication for this
scenario and changes in FW is required to mitigate this issue
gracefully.
BR,
Govind
