Subject: [PATCH 2/2] remoteproc: k3-m4: Leave crash recovery enabled
Date: Mon,  9 Nov 2026 08:48:30 +0300	[thread overview]
Message-ID: <20261109054830.42715-3-dev@chrispinetinega.com> (raw)
In-Reply-To: <20261109054830.42715-1-dev@chrispinetinega.com>

The M4 driver disables recovery, but nothing reported a crash to the
remoteproc core, so there was nothing to recover from. Now that
RP_MBOX_CRASH reaches rproc_report_crash(), recovery resets the M4F and
boots its firmware again, while Linux keeps running. The stop is a
plain reset, so it does not need the crashed core's cooperation.

Leave recovery enabled by default. Userspace can still disable it
through /sys/class/remoteproc/remoteprocN/recovery.
