Merge branch 'drm-next-5.1' of git://people.freedesktop.org/~agd5f/linux into drm-next
New stuff for 5.1. amdgpu: - DC bandwidth formula updates - Support for DCC on scanout surfaces - Support for multiple IH rings on soc15 asics - Fix xgmi locking - Add sysfs interface to get pcie usage stats - Simplify DC i2c/aux code - Initial support for BACO on vega10/20 - New runtime SMU feature debug interface - Expand existing sysfs power interfaces to new clock domains - Handle kexec properly - Simplify IH programming - Rework doorbell handling across asics - Drop old CI DPM implementation - DC page flipping fixes - Misc SR-IOV fixes amdkfd: - Simplify the interfaces between amdkfd and amdgpu ttm: - Add a callback to notify the driver when the lru changes sched: - Refactor mirror list handling - Rework hw fence processing Signed-off-by: Dave Airlie <airlied@redhat.com> From: Alex Deucher <alexdeucher@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190125231517.26268-1-alexander.deucher@amd.com
