2019-05-24drm/amd/display: Explicitly specify update type per plane info changeNicholas Kazlauskas1-24/+44
[Why] The bit for flip addr is being set causing the determination for FAST vs MEDIUM to always return MEDIUM when plane info is provided as a surface update. This causes extreme stuttering for the typical atomic update path on Linux. [How] Don't use update_flags->raw for determining FAST vs MEDIUM. It's too fragile to changes like this. Explicitly specify the update type per update flag instead. It's not as clever as checking the bits itself but at least it's correct.

2019-05-24drm/amd/display: Program VTG params after programming Global SyncJoshua Aberback4-50/+73
[Why] VTG has a parameter FP2, which is defined as: if VSTARTUP is before VSYNC: FP2 = number of lines in between VSTARTUP and VSYNC else FP2 = 0 Currently, FP2 is only programmed during "program_timing". However, the position of VSTARTUP is affected by the prefetching requirements on all pipes, so the position might change when we do memory request control on another pipe, so we need to make sure that FP2 stays up-to-date whenever we adjust VSTARTUP. [How] - refactor VTG_CONTROL programming into a new function "set_vtg_params" - call it after calling "program_global_sync" - make sure it's called after because it relies on the cached dlg params Signed-off-by: Joshua Aberback <joshua.aberback@amd.com> Reviewed-by: Tony Cheng <Tony.Cheng@amd.com> Acked-by: Bhawanpreet Lakha <Bhawanpreet.Lakha@amd.com> Acked-by: Jun Lei <Jun.Lei@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
