[PATCH 0/2] x86: Use Multiboot framebuffer

Posted by Tu Dinh Ngoc 2 years, 2 months ago

Xen does not currently use the Multiboot framebuffer. This means there
is no graphics when booting Xen with Kexec.

This patchset parses and uses the Multiboot framebuffer information
during boot.

Tu Dinh Ngoc (2):
  x86: Parse Multiboot2 framebuffer information
  x86: Set up framebuffer given by Multiboot2
