* drm/radeon: cope with foreign fences inside the reservation objectMaarten Lankhorst2014-10-031-1/+1
| | | | | | | | Not the whole world is a radeon! :-) Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Maarten Lankhorst <maarten.lankhorst@canonical.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
* drm/radeon: add the infrastructure for concurrent buffer accessChristian König2014-09-111-12/+13
| | | | | | | | This allows us to specify if we want to sync to the shared fences of a reservation object or not. Signed-off-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
* drm/radeon: Only flush HDP cache for indirect buffers from userspaceMichel Dänzer2014-08-181-1/+1
| | | | | | | | It isn't necessary for command streams generated by the kernel (at least not while we aren't storing ring or indirect buffers in VRAM). Signed-off-by: Michel Dänzer <michel.daenzer@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

* drm/radeon: use lower_32_bits where appropriateChristian König2014-06-091-4/+4
| | | | | | | | | Replace occurrences of "v & 0xffffffff" with lower_32_bits(v) when it's next to an upper_32_bits(v). Also remove unnecessary "upper_32_bits(v) & 0xffffffff" code snippets.

* drm/radeon: drop radeon_ring_force_activityChristian König2014-02-181-2/+0
| | | | | | | | | The reason for the false positives was fixed quite some time ago and since most engines can still execute NOPs while being locked up it leads to false negatives. Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com>
