Disable the DMC event handlers before loading the firmware and after uninitializing the display, to make sure the firmware is inactive. This matches the Bspec "Sequences for Display C5 and C6" page for GEN12+. Add a TODO comment for doing the same on pre-GEN12 platforms. v2: - Add a macro for the number of event handlers. - Disable the event handlers only on GEN12+. - s/dev_priv/i915/ in docbook comment.

HDMI2.1 requires some higher resolution video modes to be enumerated only if HDMI2.1 Fixed Rate Link (FRL) is supported. Current platforms do not support FRL transmission so prune modes that require HDMI2.1 FRL. v2: Fixed the condition to check for dotclock > 600. Return MODE_CLOCK_HIGH as mode status. Signed-off-by:

The issue here was on for_each_intel_encoder_mask_with_psr() over the new_crtc_state encoder mask, so if the CRTC was being disabled mask would be zero and it would not have any chance to disable PSR. So here doing for_each_intel_encoder_mask_with_psr() over the old_crtc_state encoder mask and then using the new_crtc_state to check if PSR needs to be disabled.

This patches fixes a issue but not in the right way as for_each_oldnew_intel_crtc_in_state() will interate over all CRTCs not only the crtc passed as parameter, also this two for_each loops are not necessary and only make code harder to understand.

JSP is based on ICP and we don't really need to differentiate between the two. So let's just delcare JSP to be ICP. The only slight change here is for Wa_14011294188 which we used to apply for JSP but now we'll only apply to MCC. This should be fine since the issue being dealt with was introduced in TGP and inherited into MCC. JSP being derived from ICP should not need this workaround. Signed-off-by:

Display is turned off by i915_drm_suspend() during the suspend procedure, removing the last reference of some gem objects that were used by display. The issue is that those objects are only actually freed when mm.free_work executed and that can happen very late in the suspend process causing issues. So here draining all freed objects released by display fixing suspend issues. Signed-off-by:

The ddc pin and aux channel sanitization may disable DVI/HDMI and DP, respectively, of ports parsed earlier, in "last one wins" fashion. With parsing and printing interleaved, we'll end up logging support first and disabling later anyway. Now that we've split ddi port info parsing and printing, take it further by doing the printing in a separate loop, fixing the logging. Note that this also changes the logging order from VBT child device order to port number order. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Eliminate the PIPECONF RMWs from .comit_commit() so that we can finally declare the whole vblank evade part (and the noarm() part) of the pipe commit free of register reads. Or at least I hope that's the last read... Only the i9xx/ilk codepaths need this for now, but let's add the same thing for hsw+ just in case we want to start calling that during fastsets at some point (eg. to change dithering settings/etc.). Should open up the way to start experimenting with different DSB usage approaches for pipe commits. Signed-off-by:

Currently i915 disables d3cold for i915 pci dev. This blocks D3 for i915 gfx pci upstream bridge (VSP). Let's disable d3cold at gfx root port to make sure that i915 gfx VSP can transition to D3 to save some power. We don't need to disable/enable d3cold in rpm, s2idle suspend/resume handlers. Disabling/Enabling d3cold at gfx root port in probe/remove phase is sufficient.

When the last reference of a gem object is removed it is added to the mm.free_list list and mm.free_work is queued to actually free the object. So gem objects that had their last reference removed by display during drm_atomic_helper_shutdown() are added to mm.free_list what could cause that mm.free_work is executed at the same time as intel_runtime_pm_driver_release() causing raw-wakerefs warning. So here only calling i915_gem_suspend() and by consequence i915_gem_drain_freed_objects() only after display is down making sure all display gem objecs are freed when intel_runtime_pm_driver_release() is executed.

This reverts commit 73867c87 ("drm/i915/display: Remove check for low voltage sku for max dp source rate"), which, on an i7-11850H iGPU with a Thinkpad X1 Extreme Gen 4, attached to a LG LP160UQ1-SPB1 embedded panel, causes wild flickering glitching technicolor pyrotechnics on resumption from suspend. The display shows strobing colors in an utter disaster explosion of pantone, as though bombs were dropped on the leprechauns at the base of the rainbow. Rebooting the machine fixes the issue, presumably because the display is initialized by firmware rather than by i915. Otherwise, the GPU appears to work fine. Bisection traced it back to this commit, which makes sense given the issues. Note: This re-opens, and puts back to the drawing board, https://gitlab.freedesktop.org/drm/intel/-/issues/5272 which was fixed by the regressing commit.
