I've tested it on the 4 intel laptops I have at my disposal. * Haswell with 128MB of eDRAM. * Comet Lake i7-10850H * Raptor Lake i7-1370P (with DPT, and Y-tiling). * Lunar Lake Ultra 5 228V (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. v5: * Rebase on top of git@gitlab.freedesktop.org:drm/i915/kernel.git drm-intel-next * Use struct intel_display instead of drm_i915_private. * Use iosys_map for intel_bo_panic_map(). v6: * Rebase on top of git@gitlab.freedesktop.org:drm/i915/kernel.git drm-intel-next * Use struct intel_display instead of drm_i915_private for intel_atomic_plane.c Jocelyn Falempe (8): drm/i915/fbdev: Add intel_fbdev_get_map() drm/i915/display/i9xx: Add a disable_tiling() for i9xx planes drm/i915/display: Add a disable_tiling() for skl planes drm/i915/gem: Add i915_gem_object_panic_map() drm/i915/display: Add drm_panic support drm/i915/display: Flush the front buffer in panic handler drm/i915/display: Add drm_panic support for Y-tiling with DPT drm/i915/display: Add drm_panic support for 4-tiling with DPT drivers/gpu/drm/i915/display/i9xx_plane.c | 23 +++ .../gpu/drm/i915/display/intel_atomic_plane.c | 169 +++++++++++++++++- drivers/gpu/drm/i915/display/intel_bo.c | 5 + drivers/gpu/drm/i915/display/intel_bo.h | 1 + .../drm/i915/display/intel_display_types.h | 2 + drivers/gpu/drm/i915/display/intel_fb_pin.c | 5 + drivers/gpu/drm/i915/display/intel_fb_pin.h | 2 + drivers/gpu/drm/i915/display/intel_fbdev.c | 5 + drivers/gpu/drm/i915/display/intel_fbdev.h | 6 +- .../drm/i915/display/skl_universal_plane.c | 27 +++ drivers/gpu/drm/i915/gem/i915_gem_object.h | 2 + drivers/gpu/drm/i915/gem/i915_gem_pages.c | 29 +++ drivers/gpu/drm/i915/i915_vma.h | 5 + drivers/gpu/drm/xe/display/intel_bo.c | 10 ++ drivers/gpu/drm/xe/display/xe_fb_pin.c | 5 + 15 files changed, 294 insertions(+), 2 deletions(-) base-commit: 010363c4618920838ca8777fdabd46871d289bf9 -- 2.49.0
