2024-06-04drm/i915: Fix assert on pending async-put power domain work when it requeues ↵Imre Deak
itself Commit dd839aa857eb ("drm/i915: Fix incorrect assert about pending power domain async-put work") fixed the assert about a pending work dropping a display power reference asynchronously, leading to the drm_WARN_ON(!queue_delayed_work(&power_domains->async_put_work)); warn next time around a power reference was put asynchronously, due to a stale instance of the work still being pending. However the fix didn't consider the case where multiple power reference was acquired and put, requiring the work to requeue itself. Extend the fix for this case as well canceling the pending instance of the work before it requeues itself.

2024-05-31drm/i915/display: add platform descriptorsJani Nikula
We'll need to start identifying the platforms independently in display code in order to break free from the i915 and xe IS_<PLATFORM>() macros. This is fairly straightforward, as we already identify most platforms by PCI ID in display probe anyway. As the first step, add platform descriptors with pointers to display info. We'll have more platforms than display info, so minimize duplication: - Add separate skl/kbl/cfl/cml descriptors while they share the display info. - Add separate jsl/ehl descriptors while they share the display info. Identify ADL-P (and derivatives) and DG2 descriptors by their names even though their display info is Xe LPD or HPD.

2024-05-30drm/i915: move uapi.event outside spinlock in intel_crtc_vblank_workLuca Coelho
In intel_crtc_vblank_work(), we access uapi.event before grabbing the event_lock spinlock, but modify it inside the spinlock block. This causes some static analyzers to get confused and issue a warning. The uapi.event value is not protected by the event_lock, so we can safely move it out of the protected block to prevent false positives.
