winsys/amdgpu: Handle RADEON_FLAG_NO_CPU_ACCESS
Failing to do this was resulting in the kernel driver unnecessarily leaving open the possibility of CPU access to tiled BOs. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=93862 (This change shouldn't be backported to stable branches, because released versions of xf86-video-amdgpu unnecessarily try to map the front buffer) Reviewed-by: Edward O'Callaghan <[email protected]> Reviewed-by: Christian König <[email protected]> Reviewed-by: Marek Olšák <[email protected]> Reviewed-by: Alex Deucher <[email protected]>
