| * drm/amdgpu: Use correct enum to set powergating stateStefan Agner2018-06-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use enum amd_powergating_state instead of enum amd_clockgating_state. The underlying value stays the same, so there is no functional change in practise. This fixes a warning seen with clang: drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:1930:14: warning: implicit conversion from enumeration type 'enum amd_clockgating_state' to different enumeration type 'enum amd_powergating_state' [-Wenum-conversion] AMD_CG_STATE_UNGATE); ^~~~~~~~~~~~~~~~~~~ Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

| * gpu: drm: ttm: Adding new return type vm_fault_tSouptick Joarder2018-06-191-23/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. Ref-> commit 1c8f422059ae ("mm: change return type to vm_fault_t") Previously vm_insert_{mixed,pfn} returns err which driver mapped into VM_FAULT_* type. The new function vmf_insert_{mixed,pfn} will replace this inefficiency by returning VM_FAULT_* type.
