2015-08-03drm/radeon: SDMA fix hibernation (CI GPU family).Jérôme Glisse
commit 2ba8d1bb8f6b589037f7db1f01144fc80750e8f7 upstream. In order for hibernation to reliably work we need to properly turn off the SDMA block, sadly after numerous attemps i haven't not found proper sequence for clean and full shutdown. So simply reset both SDMA block, this makes hibernation works reliably on sea island GPU family (CI) Hibernation and suspend to ram were tested (several times) on : Bonaire Hawaii Mullins Kaveri Kabini Signed-off-by: Jérôme Glisse <jglisse@redhat.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit 799028d5d85384cce140323be633c8d5f079193f upstream.

2014-03-12drm/radeon/cik: stop the sdma engines in the enable() functionAlex Deucher
We always stop the rings when disabling the engines so just call the stop functions directly from the sdma enable function. This way the rings' status is set correctly on suspend so there are no problems on resume. Fixes resume failures that result in acceleration getting disabled.

2014-03-12drm/radeon/cik: properly set sdma ring status on disableAlex Deucher
When we disable the rings, set the status properly. If not other code pathes may try and use the rings which are not functional at this point. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
2014-01-29drm/radeon: clean up active vram sizingAlex Deucher
If we are not able to properly initialize one of the gpu engines for buffer paging, we limit vram to the size of the cpu visible aperture. We generally either use the gfx or dma engine to do this. Clean up the size limiting code to only adjust the size based on what ring is selected for buffer paging rather than making assumptions about which engine is selected for paging.

2013-12-24drm/radeon: remove generic rptr/wptr functions (v2)Alex Deucher
Fill in asic family specific versions rather than using the generic version. This lets us handle asic specific differences more easily. In this case, we disable sw swapping of the rtpr writeback value on r6xx+ since the hw does it for us. Fixes bogus rptr readback on BE systems. v2: remove missed cpu_to_le32(), add comments Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
