2022-03-04drm/i915: Remove framestart_delay sanitationVille Syrjälä
Now that we track framestart_delay in the crtc state with readout and state checker support we can remove the explicit framestart_delay sanitation code. Also I'm not convinced reprogramming this while the pipe is running is even valid. CHICKEN_TRANS (hsw+) and TRANS_CHICKEN2 (cpt+) docs at least make no mention of double buffering which seems to imply that live reprogramming is not supported. On older platforms PIPECONF and PCH_TRANSCONF (ibx) are double buffered though, so might be that we could do this on the older platforms. But doesn't really make sense to special case old platforms for this. So from now on if the BIOS has misprogrammed this we shall simply do a full modeset at boot to fix it up. Such systems will of course lose fastboot, but I think less code (and less uncertainty what reprogramming this on a running pipe will even do) outweighs that.

2022-03-03drm/i915: Fix the async flip wm0/ddb optimizationVille Syrjälä
The current implementation of the async flip wm0/ddb optimization does not work at all. The biggest problem is that we skip the whole intel_pipe_update_{start,end}() dance and thus never actually complete the commit that is trying to do the wm/ddb change. To fix this we need to move the do_async_flip flag to the crtc state since we handle commits per-pipe, not per-plane. Also since all planes can now be included in the first/last "async flip" (which gets converted to a sync flip to do the wm/ddb mangling) we need to be more careful when checking if the plane state is async flip comptatible. Only planes doing the async flip should be checked and other planes are perfectly fine not adhereing to any async flip related limitations. However for subsequent commits which are actually going do the async flip in hardware we want to make sure no other planes are in the state. That should never happen assuming we did our job correctly, so we'll toss in a WARN to make sure we catch any bugs here.

2022-03-03drm/i915: Check async flip capability early onVille Syrjälä
Since the async flip state check is done very late and thus it can see potentially all the planes in the state (due to the wm/ddb optimization) we need to move the "can the requested plane do async flips at all?" check much earlier. For this purpose we introduce intel_async_flip_check_uapi() that gets called early during the atomic check. And for good measure we'll throw in a couple of basic checks: - is the crtc active? - was a modeset flagged? - is+was the plane enabled?

Currently we are observing occasional screen flickering when PSR2 selective fetch is enabled. More specifically glitch seems to happen on full frame update when cursor moves to coords x = -1 or y = -1. According to Bspec SF Single full frame should not be set if SF Partial Frame Enable is not set. This happened to be true for ADLP as PSR2_MAN_TRK_CTL_ENABLE is always set and for ADL_P it's actually "SF Partial Frame Enable" (Bit 31). Setting "SF Partial Frame Enable" bit also on full update seems to fix screen flickering. Also make code more clear by setting PSR2_MAN_TRK_CTL_ENABLE only if not on ADL_P.

2022-03-01drm/i915: make a handful of read-only arrays static constColin Ian King
Don't populate the read-only arrays on the stack but instead make them static const and signed 8 bit ints. Also makes the object code a little smaller. Reformat the statements to clear up checkpatch warning.

2022-02-28drm/i915: Move intel_display_power_well_is_enabled() to ↵Imre Deak
intel_display_power_well.c Move intel_display_power_well_is_enabled() to intel_power_well.c, as a step towards making the low-level power well internals (i915_power_well_ops/desc structs) hidden. Eventually the call to this function and in general accessing power wells directly from elsewhere in the driver should be replaced by the use of power domains. No functional change.

2022-02-28drm/i915: Add function to call a power well's sync_hw() hookImre Deak
Add a function to call a power well's sync_hw() hook, instead of open-coding the same, as a step towards making the low-level power well internals (i915_power_well_ops/desc structs) hidden. The cached-enable state should be always up-to-date, so update it whenever sync_hw() is called. No functional change.

Move the power well get/put/enable/disable hooks to the new intel_display_power_well.c file. The motivation is to reduce the clutter in intel_display_power.c, keeping the functionality related to power domains in that file and moving the low-level power well functionality to intel_display_power_well.c.
