Public bug reported: [ Impact ]
* On ARL-H, the GPU isn't supported in 6.8. As such, display is using the simpleframebuffer driver which doesn't handle going into suspend and other issues. [ Fix ] * Add support of the GPU to 6.8. As ARL-H is reusing MTL design, adding the PCI ids and few tweaks is enough to enable it. As such, 5 upstream commits that landed in 6.9 are needed : 84bf82f4f8661 drm/i915/xelpg: Extend driver code of Xe_LPG to Xe_LPG+ c5b32a4194613 drm/i915/xelpg: Add workaround 14019877138 6d46d09a0d7dd drm/i915/mtl: Wake GT before sending H2G message 93cbc1accbcec drm/i915/mtl: Add fake PCH for Meteor Lake bddacdf4861c0 drm/i915: Add additional ARL PCI IDs [ Test Plan ] * Boot ARL-H hardware and verify that the i915 is loaded.
