Subject: [RFC PATCH v3 0/6] drm/i915: Add drm_panic support

This is a draft of drm_panic support for i915.

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.

Jocelyn Falempe (6):
  drm/i915/fbdev: Add intel_fbdev_get_vaddr()
  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: Add drm_panic support
  drm/i915: Add drm_panic support for Y-tiling with DPT
