drm/radeon: don't probe MST on hw we don't support it on

2015-06-18T18:36:56+00:00

If you do radeon.mst=1 on a gpu without mst hw, and then
plug some mst hw it will oops instead of falling back.

So check we have DCE5 at least before proceeding.

drm/radeon: Add RADEON_INFO_VA_UNMAP_WORKING query

2015-06-18T18:36:56+00:00

This tells userspace that it's safe to use the RADEON_VA_UNMAP operation
of the DRM_RADEON_GEM_VA ioctl.

drm/radeon: Make sure radeon_vm_bo_set_addr always unreserves the BO

2015-06-11T14:27:54+00:00

Some error paths didn't unreserve the BO. This resulted in a deadlock
down the road on the next attempt to reserve the (still reserved) BO.

drm/radeon: fix freeze for laptop with Turks/Thames GPU.

2015-06-11T14:26:42+00:00

Laptop with Turks/Thames GPU will freeze if dpm is enabled. It seems
the SMC engine is relying on some state inside the CP engine. CP needs
to chew at least one packet for it to get in good state for dynamic
power management.

This patch simply disabled and re-enable DPM after the ring test which
is enough to avoid the freeze.

drm/radeon: partially revert "fix VM_CONTEXT*_PAGE_TABLE_END_ADDR handling"

2015-05-28T13:54:43+00:00

We have that bug for years and some users report side effects when fixing it on older hardware.

So revert it for VM_CONTEXT0_PAGE_TABLE_END_ADDR, but keep it for VM 1-15.
