Subject: [PATCH v5 0/4] remoteproc: Panic handling
Date: Mon, 23 Mar 2020 22:29:00 -0700 [thread overview]
Message-ID: <20200324052904.738594-1-bjorn.andersson@linaro.org> (raw)
Add support for invoking a panic handler in remoteproc drivers, to allow them
to invoke e.g. cache flushing on the remote processors in response to a kernel
panic - to aid in post mortem debugging of system issues.
Bjorn Andersson (4):
remoteproc: Traverse rproc_list under RCU read lock
remoteproc: Introduce "panic" callback in ops
remoteproc: qcom: q6v5: Add common panic handler
remoteproc: qcom: Introduce panic handler for PAS and ADSP
