Sure. amdxdna_cmd_set_state() updates the return code to command buffer. So
application which issues the command will be able to get the return code.
The function return value "ret" is used by mailbox receiving kernel thread to
deal with the error.
I miss a clearer answer for the indicated function call incidence.
Can it be helpful to determine the state value before it would be passed to a
concrete call?
aie2_sched_resp_handler() is called either after get the firmware
response through mailbox or the request is timed out/ canceled. So in
this handler, it based on the response to set the state field in command
buffer.
What do you mean here for "determine the state value before it would be
passed to a concrete call?". What is your concern here? Maybe you can
provide a simple patch if you think there is anything can be improved?
Thanks,
