+Subject: [PATCH] grub-core/video/efi_gop.c: Add support for BLT_ONLY adapters
+
+EFI GOP has support for multiple different bitness types of frame buffers
+and for a special "BLT only" type which is always defined to be RGBx.
+
+Because grub2 doesn't ever directly access the frame buffer but instead
+only renders graphics via the BLT interface anyway, we can easily support
+these adapters.
+
+The reason this has come up now is the emerging support for virtio-gpu
+in OVMF. That adapter does not have the notion of a memory mapped frame
+buffer and thus is BLT only.
