Subject: [PATCH v2 0/3] Add events to trace remoteproc lifecycle
Date: Mon, 16 Nov 2020 13:44:41 -0800 [thread overview]
Message-ID: <1605563084-30385-1-git-send-email-rishabhb@codeaurora.org> (raw)
Insert tracepoints in mdt_loader, qcom_scm and remoteproc_core drivers.
These tracepoints will be used to analyze the time taken
at each step during bootup/shutdown of the remoteproc. Tracepoints
in mdt_loader driver provides information about location and size
of firmware segments being loaded. Also trace the scm pas calls
used to boot/load remote processors.
Changelog:
v2 -> v1:
- Add traces in qcom_scm driver
- Add traces in remoteproc core to trace the remoteproc state
- Trace the physical address where segment is loaded in mdt_loader

soc: qcom: Add tracepoints to mdt loader
firmware: scm: Add tracepoints to scm driver for pas calls
remoteproc: Add ftrace events to trace lifecycle of remoteprocs
