drm/amdgpu: update to new mmu_notifier semantic

2017-08-31T23:12:59+00:00

Calls to mmu_notifier_invalidate_page() were replaced by calls to
mmu_notifier_invalidate_range() and are now bracketed by calls to
mmu_notifier_invalidate_range_start()/end()

Remove now useless invalidate_page callback.

drm/amdgpu: Use list_del_init in amdgpu_mn_unregister

2017-08-02T18:29:58+00:00

Otherwise bo->shadow_list (which is aliased by bo->mn_list) will not
appear empty in amdgpu_ttm_bo_destroy and cause an oops when freeing
former userptr BOs.

drm/amdgpu: Fix undue fallthroughs in golden registers initialization

2017-08-02T18:29:42+00:00

As I was staring at the si_init_golden_registers code, I noticed that
the Pitcairn initialization silently falls through the Cape Verde
initialization, and the Oland initialization falls through the Hainan
initialization. However there is no comment stating that this is
intentional, and the radeon driver doesn't have any such fallthrough,
so I suspect this is not supposed to happen.

drm/amdgpu/gfx9: simplify and fix GRBM index selection

2017-07-25T20:38:15+00:00

Copy the approach taken by gfx8, which simplifies the code, and set the
instance index properly. The latter is required for debugging, e.g. for
reading wave status by UMR.

drm/amdgpu: Fix KFD oversubscription by tracking queues correctly

2017-07-14T01:21:53+00:00

The number of compute queues available to the KFD was erroneously
calculated as 64. Only the first MEC can execute compute queues and
it has 32 queue slots.

This caused the oversubscription limit to be calculated incorrectly,
leading to a missing chained runlist command at the end of an
oversubscribed runlist.

v2: Remove unused num_mec field to avoid duplicate logic
v3: Separate num_mec removal into separate patches
