GCEA/MMHUB EA error should not result to DF freeze, this is fixed in next generation, but for some reasons the GCEA/MMHUB EA error will result to DF freeze in previous generation, diver should avoid to indicate GCEA/MMHUB EA error as hw fatal error in kernel message by read GCEA/MMHUB err status registers. Changed from V1: make query_ras_error_status function more general make read mmhub er status register more friendly Changed from V2: move ras error status query function into do_recovery workqueue Changed from V3: remove useless code from V2, print GCEA error status instance number Signed-off-by: -

[Why] When running a game/benchmark with v-sync disabled, disabling a plane (which is v-sync) can cause an underflow. This is due to flips that are pending before pipe locking being applied after locks are released and pipes have been re-arranged or disconnected. This can potentially apply a flip on the incorrect pipe. [How] Check that any pending flips are cleared before locking any pipes to ensure flips are applied on the correct pipes. Signed-off-by:

Always start vblank timer, but only calls vblank function when vblank is enabled. This is used to fix the dead lock issue. When drm_crtc_vblank_off want to disable vblank, it first get event_lock, and then call hrtimer_cancel, but hrtimer_cancel want to wait timer handler function finished.

Move doorbell allocation for a process into kfd device and allocate doorbell space in each PDD during process creation. Currently, KFD manages its own doorbell space but for some devices, amdgpu would allocate the complete doorbell space instead of leaving a chunk of doorbell space for KFD to manage. In a system with mix of such devices, KFD would need to request process doorbell space based on the type of device, either from amdgpu or from its own doorbell space. Signed-off-by:

Remember KFD module initializaton status in a global variable. Skip KFD device probing when the module was not initialized. Other amdgpu_amdkfd calls are then protected by the adev->kfd.dev check. Also print a clear error message when KFD disables itself. Amdgpu continues its initialization even when KFD failed. Signed-off-by:
