2024-06-05drm/i915: Add a separate definition for PIPE_CRC_RES_HSWVille Syrjälä2-1/+6
On hsw+ we only have one CRC result register, instead of the five we have on ivb, and some of the others have been repurposed to serve other CRC related purposes. Since the hsw+ vs. pre-hsw register operate quite differently let's add a separate definition for the hsw+ variant to make the situation a bit more clear. Also since we only use this from a hsw+ codepath there is no real benefit to be had with reusing the ivb register definition.

2024-06-04drm/i915: Fix assert on pending async-put power domain work when it requeues ↵Imre Deak1-6/+6
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.

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.
