Subject: [PATCH v2 6/6] gpu: host1x: debug: Dump push buffer state
Date: Mon, 29 Jun 2020 06:18:42 +0300	[thread overview]
Message-ID: <20200629031842.32463-7-digetx@gmail.com> (raw)
In-Reply-To: <20200629031842.32463-1-digetx-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

When job hangs and there is a memory error pointing at channel's push
buffer, it is very handy to know the push buffer's state. This patch
makes the push buffer's state to be dumped into KMSG in addition to the
job's gathers.
