commit 3899ca844b82fb201fb764f56eec483acb59a29c upstream. Need to expand the check to handle short circuiting if the selected state is the same as current state. bug: https://bugs.freedesktop.org/show_bug.cgi?id=87796 Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/radeon: drop ttm two ended allocation

2015-03-26T12:59:38Z

commit a239118a24b3bf9089751068e431dfb63dc4168b upstream. radeon_bo_create() calls radeon_ttm_placement_from_domain() before ttm_bo_init() is called. radeon_ttm_placement_from_domain() uses the ttm bo size to determine when to select top down allocation but since the ttm bo is not initialized yet the check is always false. It only took effect when buffers were validated later. It also seemed to regress suspend and resume on some systems possibly due to it not taking effect in radeon_bo_create(). radeon_bo_create() and radeon_ttm_placement_from_domain() need to be reworked substantially for this to be optimally effective. Re-enable it at that point. Noticed-by: Oded Gabbay Reviewed-by: Christian König Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/radeon: Changing number of compute pipe lines

2015-03-26T12:59:38Z

commit e405ca3a1bf166f741506c07c2a277b5d48af8f7 upstream. The current CP firmware can handle Usermode Queues only on MEC1. To reflect this firmware change, this commit reduces number of compute pipelines to 4 - 1, from 8 - 1 (the first pipeline is allocated for kgd).

drm/radeon: fix wait to actually occur after the signaling callback

2015-03-26T12:59:38Z

commit b6610101718d4ab90d793c482625e98eb1262cad upstream. A normal wait adds to the front of the tail. By doing something similar to fence_default_wait the fence code can run without racing. This is a complete fix for "panic on suspend from KDE with radeon", and a partial fix for "Radeon: System pauses on TAHITI". On tahiti si_irq_set needs to be fixed too, to completely flush the writes before radeon_fence_activity is called in radeon_fence_enable_signaling.
