[PULL] drm-intel-gt-next

[Joonas Lahtinen <joonas.lahtinen@linux.intel.com>]

Hi Dave & Daniel,

Here goes the drm-intel-gt-next PR for 5.11.

Most importantly there is a healthy chunk of Tigerlake
related fixes and a fix for user reported issue #2381 where
graphics output would stop at "switching to inteldrmfb from
simple".

Fixes to DMA mapped sg usage in i915 to unblock intel iommu
rework. Fixes to previously introduced WW mutex rework.

We're enabling eLLC for displayable buffers on SKL+. Plenty
of fixes to driver unbind/bind cycle. The GuC firmware
version is being updated (that just loads HuC for now).

The usual amount of fixes for CI found corner cases.

Expect a few conflicts with drm-intel-next (resolved in rerere)
as the platform enabling ones go there. I'll backmerge drm-next
once you've accepted this to pull all the changes to gt-next.

The -next-fixes and -fixes would come from Jani after this is
accepted, too.

Regards, Joonas
