I've tested it on the 4 intel laptops I have at my disposal. * Haswell with 128MB of eDRAM. * Comet Lake. * Alder Lake (with DPT, and Y-tiling). * Lunar Lake (with DPT, and 4-tiling, and using the Xe driver. 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. v4: * Add support for Xe driver, which shares most of the code. * Add support for 4-tiled framebuffer found in newest GPU.
