Subject: [PATCH] gpu: host1x: Initialize firewall class to the jobs one
Date: Sun, 14 May 2017 00:01:14 +0300	[thread overview]
Message-ID: <20170513210114.31680-1-digetx@gmail.com> (raw)

The commands stream is prepended by the jobs class on the CDMA submission,
so that explicitly setting a module class in the commands stream isn't
necessary. The firewall initializes its class to 0 and the command stream
that doesn't explicitly specify the class effectively bypasses the firewall.
