Good call on having the crash log in the original submission. Extra information can trivially be removed ;-) With that and the small nitpick below the patch is: Reviewed-by: Emil Velikov <emil.veli...@collabora.com> Personally I won't bother re-sending the patch. Simply fixup locally and commit. >> > >> > + #ifdef HAVE_DRM_GRALLOC Please move this (and the else/endif) at the start of the line. We don't indent pre-processor directives in Mesa (modulo odd case that slipped).
