Subject: [PATCH] drm/radeon: fix VCE fence command
Date: Tue, 15 Apr 2014 00:10:22 +0200 [thread overview]
Message-ID: <1397513422-1566-1-git-send-email-christophjaeger@linux.com> (raw)
Due to a type mismatch that causes an implicit type conversion, the
upper 32 bits of the GPU address have been zeroed out when adding to the
command buffer.
Picked up by Coverity - CID 1198624.
