Which method is used to flush tlb does not depend on whether a reset is in progress or not. We should skip flush altogether if the GPU will get reset. So put both path under reset_domain read lock. Signed-off-by:

Here since we are in reset and takes the reset_domain write side lock already. We can't use the flush tlb helper which tries to take the read side. Signed-off-by:

is_hws_hang and is_resetting serves pretty much the same purpose and they all duplicates the work of the reset_domain lock, just check that directly instead. This also eliminate a few bugs listed below and get rid of dqm->ops.pre_reset. kfd_hws_hang did not need to avoid scheduling another reset. If the on-going reset decided to skip GPU reset we have a bad time, otherwise the extra reset will get cancelled anyway. remove_queue_mes forgot to check is_resetting flag compared to the pre-MES path unmap_queue_cpsch, so it did not block hw access during reset correctly.

We send back the ready to reset message before we stop anything. This is wrong. Move it to when we are actually ready for the FLR to happen. In the current state since we take tens of seconds to stop everything, it is very likely that host would give up waiting and reset the GPU before we send ready, so it would be the same as before. But this gets rid of the hack with reset_domain locking and also let us tell how slow ready to reset actually is from the host. The ready to reset speed can be improved later. Signed-off-by:

[Description] In newer DCN's the programming of SYMCLK_FE_SRC_SEL depends on the value of DIG_FE_SOURCE_SELECT. If DIG_FE_SOURCE_SELECT is not already programmed at the time of PHY / DIG enable then the FW sequence will program an incorrect SYMCLK source. Ensure that we program DIG_FE_SOURCE_SELECT for all DIO scenarios (DVI in this particular case) before going through the PHY / DIG enable sequence. Reviewed-by:

drm/amd/display: Add NULL check for 'afb' before dereferencing in amdgpu_dm_plane_handle_cursor_update This commit adds a null check for the 'afb' variable in the amdgpu_dm_plane_handle_cursor_update function.

These variables were previously assumed to be null at line 922, but they were used later in the code without checking if they were null.
