2022-06-07drm/amd/display: add DP sanity checks during enable streamWenjing Liu4-6/+15
[why] 1. When HPD deassertion is pulled in the middle of enabe stream link training, we will abort current training and turn off PHY. This causes current link settings to be zeroed this causes later stream enablement sequence to fail as we prefer to carry on enablement process despite of link training failure for SST. 2. When HPD is toggled after detection before before the enable stream sequence as a result. There could be a race condition where we could end up enable stream based on the previous link even though the link is updated after the HPD toggle. This causes an issue where our link bandwidth is no longer enough to accommodate the timing therefore causes us to oversubscribe MST payload time slots. As discussed we decided to add basic sanity check to make sure that our code can handle the oversubscription failure silently without system hang. [how] 1. Keep PHY powered on when HPD is deasserted during enable stream and wait for the detection sequence to power it off later. 2. Do not allocate payload if the required timeslot for current timing is greater than 64 timeslots.

2022-06-06drm/amd/display: Implement MPO PSR SULeo Li2-4/+144
[WHY] For additional power savings, PSR SU (also referred to as PSR2) can be enabled on eDP panels with PSR SU support. PSR2 saves more power compared to PSR1 by allowing more opportunities for the display hardware to be shut down. In comparison to PSR1, Shut down can now occur in-between frames, as well as in display regions where there is no visible update. In otherwords, it allows for some display hw components to be enabled only for a **selectively updated** region of the visible display. Hence PSR SU. [HOW] To define the SU region, support from the OS is required. OS needs to inform driver of damaged regions that need to be flushed to the eDP panel. Today, such support is lacking in most compositors. Therefore, an in-between solution is to implement PSR SU for MPO and cursor scenarios. The plane bounds can be used to define the damaged region to be flushed to panel. This is achieved by: * Leveraging dm_crtc_state->mpo_requested flag to identify when MPO is enabled. * If MPO is enabled, only add updated plane bounds to dirty region. Determine plane update by either: * Existence of drm damaged clips attached to the plane (added by a damage-aware compositor) * Change in fb id (flip) * Change in plane bounds (position and dimensions) * If cursor is enabled, the old_pos and new_pos of cursor plus cursor size is used as damaged regions(*). (*) Cursor updates follow a different code path through DC. PSR SU for cursor is already implemented in DC, and the only thing required to enable is to set DC_PSR_VERSION_SU_1 on the eDP link. See dcn10_dmub_update_cursor_data().

2022-06-06drm/amd/display: calculate psr config settings in runtime in DMDavid Zhang1-5/+10
[why] Currently the psr configuration parameters are hardcoded before feeding into the DC helper before passing to DMUB FW. We'd rework to call a shared helper to calculate/update generic psr config fields which are relying on the stream timing and eDP sink PSR caps to avoid hard-coding. [how] - drop part of hard-coded psr config fields by replacing w/ the call of helper from DM before feeding into DC link setup psr helper - For those DM specific psr config fields, e.g. allow smu opt, is not to be set/updated from the shared helper but to rely on the DC feature mask - for the psr version field in psr_config structure, since only the field psr_version of DC link psr_settings matters for that fed to DMUB FW, thus no need to set/update the psr_version field of psr_config structure.

2022-06-03drm/amd/display: FCLK P-state support updatesChaitanya Dhere2-5/+7
[Why] Previously we used to send FCLK P-state enable messages upon each call to update_clocks based on dml output. This resulted in increased message transactions between DC and PMFW. [How] Update the code to check safe_to_lower status and send the message based on dml input only on boot. This reduces message transactions. Also remove other unwanted code based on current code status. Signed-off-by: Chaitanya Dhere <chaitanya.dhere@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2022-06-03drm/amd/display: Introduce new update_clocks logicJun Lei1-52/+73
[why] DCN has sidebands to control some clocks, it is useful for clk_mgr to always update the clocks it explicitly controls rather than skip them because it enables more configurations to work without SMU [how] only skip handling clocks where SMU manages the frequency for clocks with DENTIST sideband (DISP/DPP), only skip the voltage request when SMU not available, but otherwise proceed normally Signed-off-by: Jun Lei <Jun.Lei@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2022-06-03drm/amd/display: do not override CURSOR_REQ_MODE when SubVP is not enabledSamson Tam1-2/+5
[Why] HUBP_UNBOUNDED_REQ_MODE and CURSOR_REQ_MODE are normally set together. In hubp32_prepare_subvp_buffering() call, CURSOR_REQ_MODE is set based on whether SubVP is enabled or not. For non MPO case, both REQ_MODE registers are set to 1. But since SubVP is not enabled, then CURSOR_REQ_MODE is set to 0, overriding the previous value. [How] Do not set CURSOR_REQ_MODE to 0 if SubVP is not enabled. This will allow CURSOR_REQ_MODE to stay as 1 in the non MPO case. Add note to follow up and check case for single pipe MPO and SubVP enabled as this would cause both REQ_MODE registers to be set to 0 but SubVP enabled would override CURSOR_REQ_MODE to 1.
