From 62f837e2ea7b854215efb2e110b176dad61c2af0 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Michel=20D=C3=A4nzer?= Date: Tue, 26 Jan 2016 16:15:59 +0900 Subject: [PATCH] winsys/amdgpu: Handle RADEON_FLAG_NO_CPU_ACCESS MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Failing to do this was resulting in the kernel driver unnecessarily leaving open the possibility of CPU access to tiled BOs.
