| * drm/radeon: remove init of CIK VMIDs 8-16 for amdkfdOded Gabbay2017-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | VMIDs 8-16 in Kaveri were reserved for use by the amdkfd driver. Because we removed amdkfd support from radeon, those VMIDs are now used by radeon and are initialized by radeon. This patch removes the function that initialized those VMIDs for amdkfd use. This initialization overridden the radeon initialization and caused GPU faults and GUI crashed.

| * drm/amd/display: Do DC mode-change check when adding CRTCsLeo (Sunpeng) Li2017-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Within atomic check, dm_update_crtcs_state is called twice. First to remove from the dc_state, and subsequently to add to it. In both calls, a secondary mode-change check is done using dc-level states. We shouldn't be doing this while removing, since a new dc_stream_state has not been created to do the necessary comparison. Because of this, the mode_changed flag within the DRM state can be mistakenly set to false. Doing so only when adding prevents this. We are also guaranteed that a call to add will come after remove, or else the atomic check fails (and a commit will not happen).

| * drm/amdgpu: move UVD/VCE and VCN structure out from unionLeo Liu2017-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the enablement of VCN Dec and Enc from user space, User space queries kernel for the IP information, if HW has UVD/VCE, the info comes from these IP blocks, but this could end up mis-interpret for VCN when they are in the union, the other way same when HW with VCN block.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The malidp_hw_device structure that the driver uses to handle the differences between versions of the IP contains both non-changeable data and fields that get updated at probe time. Previously we were copying the read-only part into allocated memory, but that can be completely avoided by splitting the structure into a read-only part and keeping the runtime modifiable fields into the old structure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference() and drm_*_unreference() helpers. drm_*_reference() and drm_*_unreference() functions are just compatibility alias for drm_*_get() and drm_*_put() and should not be used by new code. So convert all users of compatibility functions to use the new APIs.
