This change reorganizes and cleanups our patches to reduce the patch number from 314 patches to 187. That's achieved by dropping patches that are later reverted and squashing fixes for earlier patches that introduced features. There are no code changes and the diff with upstream is the same before and after the cleanup. Having fewer patches makes easier to manage the patchset and also will ease to rebase them on top of the latest grub-2.04 release. Signed-off-by: Javier Martinez Canillas <javierm@redhat.com>

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.
