[PATCH v2 0/3] Add events to trace remoteproc lifecycle

From: Rishabh Bhatnagar
Date: Mon Nov 16 2020 - 16:45:13 EST


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

Rishabh Bhatnagar (3):
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
