Subject: [PATCH v2 7/8] drm/lima: increase default job timeout to 10s
Date: Wed, 24 Jan 2024 03:59:46 +0100	[thread overview]
Message-ID: <20240124025947.2110659-8-nunes.erico@gmail.com> (raw)
In-Reply-To: <20240124025947.2110659-1-nunes.erico@gmail.com>

The previous 500ms default timeout was fairly optimistic and could be
hit by real world applications. Many distributions targeting devices
with a Mali-4xx already bumped this timeout to a higher limit.
We can be generous here with a high value as 10s since this should
mostly catch buggy jobs like infinite loop shaders, and these don't
seem to happen very often in real applications.
