[PATCH v2 0/3] gfx: improvements when using multiboot2 and EFI

Posted by Roger Pau Monne 1 year, 1 month ago

Hello,

The following series contains some fixes and improvements related to
graphics usage when booting Xen.

Proposed patches fix some shortcomings when using multiboot2, mostly the
ignoring of the console=vga (or lack of) and the vga=gfx- parameters.
It also switches default Xen behaviour from trying to reuse the
currently set GOP mode instead of attempting to set the maximum
supported resolution.

Thanks, Roger.

Roger Pau Monne (3):
  efi: try to use the currently set GOP mode
  multiboot2: parse console= and vga= options when setting GOP mode
  multiboot2: do not set StdOut mode unconditionally
