2023-10-16drm: renesas: shmobile: Wait for page flip when turning CRTC offGeert Uytterhoeven2-0/+40
Turning a CRTC off will prevent a queued page flip from ever completing, potentially confusing userspace. Wait for queued page flips to complete before turning the CRTC off to avoid this.

There is no need to call drm_plane_force_disable() from the plane's .destroy() callback, as the plane should have been disabled already before. See also commit 3c858a33858baa8c ("drm/plane_helper: don't disable plane in destroy function") for the generic plane helper case.

The SH-Mobile LCD Controller is part of a PM Domain on all relevant SoCs (clock domain on all, power domain on some). Hence it may not be sufficient to manage the LCDC module clock explicitly (e.g. if the selected clock source differs from SHMOB_DRM_CLK_BUS). Fix this by using Runtime PM for all clock handling.

2023-09-28drm/i915/fdi: Recompute state for affected CRTCs on FDI linksImre Deak3-0/+52
Recompute the state of all CRTCs on an FDI link during a modeset that may be affected by the modeset of other CRTCs on the same link. This ensures that each CRTC on the link maximizes its BW use (after another CRTC is disabled). In practice this means recomputing pipe B's config on IVB if pipe C gets disabled. v2: - Add the change recomputing affected CRTC states in a separate patch.

2023-09-28drm/i915/fdi: Improve FDI BW sharing between pipe B and CImre Deak9-40/+140
At the moment modesetting pipe C on IVB will fail if pipe B uses 4 FDI lanes. Make the BW sharing more dynamic by trying to reduce pipe B's link bpp in this case, until pipe B uses only up to 2 FDI lanes. For this instead of the encoder compute config retry loop - which reduced link bpp only for the encoder's pipe - reduce the maximum link bpp for pipe B/C as required after all CRTC states are computed and recompute the CRTC states with the new bpp limit. Atm, all FDI encoder's compute config function returns an error if a BW constrain prevents increasing the pipe bpp value. The corresponding crtc_state->bw_constrained check can be replaced with checking crtc_state->max_link_bpp_x16, add TODO comments for this. SDVO is an exception where this case is only handled in the outer config retry loop, failing the modeset with a WARN, add a FIXME comment to handle this in the encoder code similarly to other encoders. v2: - Don't assume that a CRTC is already in the atomic state, while reducing its link bpp. - Add DocBook description to intel_fdi_atomic_check_link(). v3: - Enable BW management for FDI links in a separate patch. (Ville) v4: (Ville) - Fail the SDVO encoder config computation if it doesn't support the link bpp limit. - Add TODO: comments about checking link_bpp_x16 instead of bw_constrained. v5: - Replace link bpp limit check with a FIXME: comment in intel_sdvo_compute_config().

2023-09-28drm/i915: Add helpers for BW management on shared display linksImre Deak7-5/+311
At the moment a modeset fails if the config computation of a pipe can't fit its required BW to the available link BW even though the limitation may be resolved by reducing the BW requirement of other pipes. To improve the above this patch adds helper functions checking the overall BW limits after all CRTC states have been computed. If the check fails the maximum link bpp for a selected pipe will be reduced and all the CRTC states will be recomputed until either the overall BW limit check passes, or further bpp reduction is not possible (because all pipes/encoders sharing the link BW reached their minimum link bpp). Atm, the MST encoder allocates twice the required BW for YUV420 format streams. A follow-up patchset will fix that, add a code comment about this. This change prepares for upcoming patches enabling the above BW management on FDI and MST links. v2: - Rename intel_crtc_state::max_link_bpp to max_link_bpp_x16 and intel_link_bw_limits::max_bpp to max_bpp_x16. (Jani) v3: - Add the helper functions in a separate patch. (Ville) - Add the functions to intel_link_bw.c instead of intel_atomic.c (Ville) - Return -ENOSPC instead of -EINVAL to userspace in case of a link BW limit failure. v4: - Make intel_atomic_check_config() static. v5: (Ville) - Rename intel_link_bw_limits::min_bpp_pipes to min_bpp_reached_pipes and intel_link_bw_reset_pipe_limit_to_min() to intel_link_bw_set_min_bpp_for_pipe(). - Rename pipe_bpp to link_bpp in intel_link_bw_reduce_bpp(). - Add FIXME: comment about MST encoder's YUV420 BW allocation and tracking the link bpp limit accordingly. v6: - Move intel_link_bw_compute_pipe_bpp() to intel_fdi.c (Ville) - WARN_ON(BIT(pipe) & min_bpp_reached_pipes) in intel_link_bw_set_bpp_limit_for_pipe().

2023-09-27drm/i915/dsb: Use DEwake to combat PkgC latencyVille Syrjälä3-14/+82
Normally we could be in a deep PkgC state all the way up to the point when DSB starts its execution at the transcoders undelayed vblank. The DSB will then have to wait for the hardware to wake up before it can execute anything. This will waste a huge chunk of the vblank time just waiting, and risks the DSB execution spilling into the vertical active period. That will be very bad, especially when programming the LUTs as the anti-collision logic will cause DSB to corrupt LUT writes during vertical active. To avoid these problems we can instruct the DSB to pre-wake the display engine on a specific scanline so that everything will be 100% ready to go when we hit the transcoder's undelayed vblank. One annoyance is that the scanline is specified as just that, a single scanline. So if we happen to start the DSB execution after passing said scanline no DEwake will happen and we may drop back into some PkgC state before reaching the transcoder's undelayed vblank. To prevent that we'll use the "force DEwake" bit to manually force the display engine to stay awake. We'll then have to clear the force bit again after the DSB is done (the force bit remains effective even when the DSB is otherwise disabled).
