Message-ID: <20200424200135.28825-1-mathieu.poirier@linaro.org> (raw)

This is the third revision of this series that tries to address the
problem of synchronising with a remote processor with as much
flexibility as possible.

Two things to pay attention to:

1) Function rproc_actuate() has been abandoned to avoid creating another
   way to start a remote processor from a kernel driver.  Arnaud expressed
   the opinion that it is semantically questionnable to synchronise with a
   remote processor when calling rproc_boot().  We could rename
   rproc_boot() to rproc_actuate() but I'll wait to see what other people
   think before doing so.

2) The allocation of the synchronisation states has been split from the
   remote processor allocation.  A new function rproc_set_state_machine()
   does all the work now.  Proceeding this way has made the patchset a
   lot more simple.

Other than the above I have tried to address all the comments made on the
second revision.  If a comment was not addressed it simply fell through
the cracks rather than ignored.  In such a case please reiterate your point
of view and I'll be sure to address it.    

Applies cleanly on rproc-next (305ac5a766b1).

Best regards,
Mathieu
