I've tested it on the 3 intel laptops I have at my disposal. one Haswell with 128MB of eDRAM, one Cometlake and one Alderlake. I tested panic in both fbdev console and gnome desktop. Best regards, v2: * Add the proper abstractions to build also for Xe. * Fix dim checkpatch issues. v3: * Add support for Y-tiled framebuffer when DPT is enabled.
