From: Matthew Nicholls Date: Mon, 29 Jan 2018 16:26:18 +0000 (+0000) Subject: radv: remove predication on cache flushes X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ef272b161e05e8216f2d1f4df5023f3aed0ae4fa;p=mesa.git radv: remove predication on cache flushes This can lead to a situation where cache flushes could get conditionally disabled while still clearing the flush_bits, and thus flushes due to application pipeline barriers may never get executed. Fixes: a6c2001ace (radv: add support for cmd predication.)
