Subject: [PATCH 3/6] remoteproc: sysmon: Inform current rproc about all active rprocs
Date: Wed, 19 Feb 2020 18:57:42 -0800 [thread overview]
Message-ID: <1582167465-2549-4-git-send-email-sidgup@codeaurora.org> (raw)
In-Reply-To: <1582167465-2549-1-git-send-email-sidgup@codeaurora.org>
A remoteproc that has just recovered from a crash will not be aware of the
state of other remoteprocs. Send sysmon notifications on behalf of all the
active/online remoteprocs to the one that just booted up.
