drm/amd/display: Fix nanosec stat overflow

2024-04-13T10:51:38Z

[ Upstream commit 14d68acfd04b39f34eea7bea65dda652e6db5bf6 ] [Why] Nanosec stats can overflow on long running systems potentially causing statistic logging issues. [How] Use 64bit types for nanosec stats to ensure no overflow. Reviewed-by: Rodrigo Siqueira Tested-by: Daniel Wheeler Signed-off-by: Aric Cyr Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/amd/display: Reinstate LFC optimization

2023-10-10T19:46:38Z

[ Upstream commit ded6119e825aaf0bfc7f2a578b549d610da852a7 ] [why] We want to streamline the calculations made when entering LFC. Previously, the optimizations led to screen tearing and were backed out to unblock development. [how] Integrate other calculations parameters, as well as screen tearing, fixes with the original LFC calculation optimizations.

[Why] Video Timing Extended Metadata packet (VTEM) is not specific to freesync. So move it out of freesync module [How] - Moved VTEM from freesync module to info_packet module - Created new structure for VTEM parameters that can be used for VRR and FVA Signed-off-by: Ahmad Othman Reviewed-by: Chris Park Acked-by: Ahmad Othman Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher

drm/amd/display: move vmid determination logic to a module

2019-06-22T14:34:14Z

Currently vmid is decided internally inside dc. With the introduction of new asics we are required to coordinate vmid use with external components. This change converts vmid logic to a DAL module allowing vmid to be passed in as a parameter to DC.

drm/amd/display: Pass app_tf by value rather than by reference

2019-02-28T03:23:55Z

Clang warns when an expression that equals zero is used as a null pointer constant (in lieu of NULL): drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:4435:3: warning: expression which evaluates to zero treated as a null pointer constant of type 'const enum color_transfer_func *' [-Wnon-literal-null-conversion] TRANSFER_FUNC_UNKNOWN, ^~~~~~~~~~~~~~~~~~~~~ 1 warning generated. This warning is caused by commit bb47de736661 ("drm/amdgpu: Set FreeSync state using drm VRR properties") and it could be solved by using NULL instead of TRANSFER_FUNC_UNKNOWN or casting TRANSFER_FUNC_UNKNOWN as a pointer. However, after looking into it, there doesn't appear to be a good reason to pass app_tf by reference as it is never mutated along the way. This is the only code path in which app_tf is used: mod_freesync_build_vrr_infopacket -> build_vrr_infopacket_v2 -> build_vrr_infopacket_fs2_data Neither mod_freesync_build_vrr_infopacket or build_vrr_infopacket_v2 modify app_tf's value and build_vrr_infopacket_fs2_data expects just the value so we can avoid dereferencing anything by just passing in app_tf's value to mod_freesync_build_vrr_infopacket and build_vrr_infopacket_v2. There is no functional change because build_vrr_infopacket_fs2_data doesn't do anything if TRANSFER_FUNC_UNKNOWN is passed to it, the same as not calling build_vrr_infopacket_fs2_data at all like before this change when NULL was used for app_tf.
