drm/amd/display: fix odm scaling

2025-04-10T12:30:52+00:00

[ Upstream commit 6566cae7aef30da8833f1fa0eb854baf33b96676 ] There are two issues with scaling calculations, odm recout calculation and matching viewport to actual recout. This change fixes both issues. Odm recout calculation via special casing and viewport matching issue by reworking the viewport calcualtion to use scaling ratios and recout to derrive the required offset and size.

drm/amd/display: Remove interface for periodic interrupt 1

2022-10-26T11:25:50+00:00

[ Upstream commit 97d8d6f075bd8f988589be02b91f6fa644d0b0b8 ] [why] Only a single VLINE interrupt is available so interface should not expose the second one which is used by DMU firmware. [how] Remove references to periodic_interrupt1 and VLINE1 from DC interfaces.

drm/amd/display: Calc DLG from dummy p-state if full p-state unsupported

2020-09-29T20:08:50+00:00

[Why] Currently, when full p-state changes are not supported, DLG parameters are calculated for no p-state support at all. However, we are required to always support dummy p-state changes, so we should instead calculate DLG based on dummy p-state latency when full p-state is unsupported. This behaviour already exists for DCN2. [How] - move DLG calculation inside WM calculation - if p-state unsupported, do not recalculate for set A, instead copy from set C, and perform DLG calculation with dummy p-state latency Signed-off-by: Joshua Aberback Reviewed-by: Jun Lei Acked-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

drm/amd/display: Check for flip pending before locking pipes.

2020-09-22T16:28:56+00:00

[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.

drm/amd/display: Rename set_mst_bandwidth to align with DP spec

2020-09-15T21:52:41+00:00

[Why] The function set_mst_bandwidth is poorly name since it isn't clear what it does, and it also does not reflect any part of the allocation sequence described in the DP spec.

drm/amd/display: Detect plane change when detect pipe change.

2020-09-15T21:52:40+00:00

[Why] If plane has changed, dcn20_detect_pipe_changes doesn't update dc_plane_state->update_flags, and the following dcn20_program_pipe can't reprogram hubp correctly. [How] Add a new flags bit "plane_changed" in pipe_ctx->update_flags.If old plane isn’t identical to new plane, this bit will be set and guide “dcn20_program_pipe” to programing HUBP correctly.

drm/amd/display: Send DISPLAY_OFF after power down on boot

2020-08-26T20:40:17+00:00

[WHY] update_clocks might not be called on headless adapters. This means DISPLAY_OFF may not be sent in headless cases. [HOW] If hardware is powered down on boot because it is headless (mode set does not happen on that adapter) also send DISPLAY_OFF notification.
