Move the flip_pending assignment into __intel_fbc_post_update() from intel_fbc_post_update(). Now mirrors the pre_update() side. The only reason the assignment was in the higher level function is that we used to call __intel_fbc_post_update() from elsewhere as well. That got cleaned up in commit b39d2c62 ("drm/i915/fbc: Call intel_fbc_activate() directly from frontbuffer flush") Signed-off-by:

All of the functions used for intel_dvo_dev_ops.mode_valid have a return type of enum drm_mode_status, but the mode_valid field in the struct definition has a return type of int. The mismatched return type breaks forward edge kCFI since the underlying function definitions do not match the function hook definition. The return type of the mode_valid field should be changed from int to enum drm_mode_status. Reported-by:

The TV encoder has its own special clocking strategy, which means we can't just use intel_crtc_dotclock() to figure out what the resulting dotclock will be given the actual DPLL port_clock. Additionally the DPLL can't always generate exactly the frequency we initially asked for. This results in us computing a bogus dotclock/etc., and it won't match the readout which is handled by the encoder itself properly. Naturally the state checker becomes unhappy with the mismatch. To do this sanely we'll need to move the DPLL computation into encoder->compute_config() so that all the derived state gets correctly computed based on the actual DPLL output frequency. Start doing that just for the TV encoder initally as intel_crtc_dotclock() should be able to handle other encoder types well enough. Though eventually this should be done for all encoder types rather than doing it from intel_crtc_compute_config(). With this we actually do some of the DPLL state computation twice, but we can skip the second actual .find_dpll() search by flagging .clock_set=true after we've done it once. We also still need to avoid clobbering the correct adjusted_mode.crtc_clock set up by encoder->compute_config() when called a second time from intel_crtc_compute_config().

When an MST connector stays enabled during a commit the connector's MST state needs to be added to the atomic state, but the corresponding MST payload allocation shouldn't be set for deletion; fix such modesets by ensuring the above even if the connector was already enabled before the modeset.

On BDW+ M/N are double buffered and so we can easily reprogram them during a fastset. So for eDP panels that support seamless DRRS we can just change these without a full modeset. For earlier platforms we'd need to play tricks with M1/N1 vs. M2/N2 during the fastset to make sure we do the switch atomically. Not sure the added complexity is worth the hassle, so leave it alone for now. The slight downside is that we have to keep the link running at a link rate capable of supporting the highest refresh rate we want to use. For the moment we just pick the highest mode the panel reports and calculate the link based on that. This might need further refinement (eg. if we run into bandwidth restrictions)... v2: Only use the high link rate if the platform really supports the seamless M/N change uring fastset (ie. bdw+) v3: Rebase due to HAS_DOUBLE_BUFFERED_M_N() Reviewed-by:
