But the graphics do work before this commit. I checked out the kernel tree on this commit and it just fails to create the framebuffer with no messages whatsoever: versatile-tft-panel 10000000.sysreg:display@0: no panel detected drm-clcd-pl111 dev:20: set up callbacks for Versatile PL110 drm-clcd-pl111 dev:20: found bridge on endpoint 1 drm-clcd-pl111 dev:20: Using non-panel bridge [drm] Supports vblank timestamp caching Rev 2 (21.10.2013). [drm] No driver support for vblank timestamp query. [drm] Initialized pl111 1.0.0 20170317 for dev:20 on minor 0 I guess this somehow broke it, then some more stuff down the road made the damage more visible. I'm trying to see if I can fix it, any hints welcome!
