* drm/amd/display: Add vrr_active_variable to dc_stream_updateHarry VanZyllDeJong2022-06-151-2/+1
| | | | | | | | | | | | | | | [WHY] The display driver on some OSes need to track it in order to perform memory clock switching decisions. [HOW] Propagate the vrr active state to dirty bit so that on mode set it disables dynamic memory clock switching.

* drm/amd/display: Firmware assisted MCLK switch and FSFelipe Clark2022-06-151-0/+4
| | | | | | | | | | | | | | | | | | | [WHY] Memory clock switching has great potential for power savings. [HOW] The driver code was modified to notify the DMCUB firmware that it should stretch the vertical blank of frames when a memory clock switch is about to start so that no blackouts happen on the screen due to unavailability of the frame buffer. The driver logic to determine when such firmware assisted strategy can be initiated is also implemented and consists on checking prerequisites of the feature.

* drm/amd/display: Add flip interval workaroundAngus Wang2022-04-051-0/+12
| | | | | | | | | | | | | | | | | | | | [WHY] Some games experience low FPS issues when FreeSync is on and VSync is toggled to half refresh rate. [HOW] First create a function to determine workaround conditions, which is when we detect 2 or more VSync interrupts between flips and a very short VSync to flip interval. We do the workaround during VSync interrupts and set the v_total_max and min to nominal. We also cleanup after we exit the game.

| | | | | | | | | | | | | | [Why] Change set_drr to pass in the entire dc_crtc_timing_adjust structure instead of passing in the parameters individually.

| | | | | | | | | | | | | | | | [Why] In cases where refresh range is slightly below 10, FreeSync is not active or supported.

* drm/amd/display: Pass app_tf by value rather than by referenceNathan Chancellor2019-02-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
