Chris Wilson ccc9e67ab2 drm/i915/display: Defer initial modeset until after GGTT is initialised ... Prior to sanitizing the GGTT, the only operations allowed in intel_display_init_nogem() are those to reserve the preallocated (and active) regions in the GGTT leftover from the BIOS. Trying to allocate a GGTT vma (such as intel_pin_and_fence_fb_obj during the initial modeset) may then conflict with other preallocated regions that have not yet been protected. Move the initial modesetting from the end of init_nogem to the beginning of init so that any vma pinning (either framebuffers or DSB, for example), is after the GGTT is ready to handle it. This will prevent the DSB object from being destroyed too early: [ 53.449241] BUG: KASAN: use-after-free in i915_init_ggtt+0x324/0x9e0 [i915] [ 53.449309] Read of size 8 at addr ffff88811b1e8070 by
