[0/9] remoteproc: qcom: post mortem debug support

Message

Bjorn Andersson Aug. 7, 2019, 5:39 a.m. UTC

The following series introduces two components that aids in post mortem
debugging of Qualcomm systems. The first part is used to store information
about loaded images in IMEM, for post mortem tools to know where the kernel
loaded the remoteproc firmware. The second part invokes a stop operation on the
remoteprocs during a kernel panic, in order to trigger them to flush caches
etc.
