Subject: [PATCH] drm/etnaviv: relax submit size limits
Date: Thu,  6 Jan 2022 19:10:21 +0100	[thread overview]
Message-ID: <20220106181021.3760251-1-l.stach@pengutronix.de> (raw)

While all userspace tried to limit commandstreams to 64K in size,
a bug in the Mesa driver lead to command streams of up to 128K
being submitted. Allow those to avoid breaking existing userspace.

Fixes: 6dfa2fab8ddd ("drm/etnaviv: limit submit sizes")
Cc: stable@vger.kernel.org
Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
