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.
