efifb (EFI frame buffer) doesn't work in RHEL-6.3 guests on RHEL-6.3
qemu-kvm without the "pci=nocrs" guest kernel parameter. This is because
dynamic MMIO range allocation places the emulated Cirrus card's frame
buffer much lower than specified in the _CRS. Try to sync the related
bits.
v1->v2:
- dropped most of v1 and started from scratch
- ASL / AML heavily based on SeaBIOS commit 2062f2ba by Gerd Hoffmann
<kra...@redhat.com>
- to be applied on top of:
- (svn rev 13538)
- Bei Guan's patch in
<caeqjb-tt0fxup3fjnd+cn7clk5jdjpgjpqpbc+amt+28ohd...@mail.gmail.com>
- my first two patches in <5000520c.6020...@redhat.com>
v2->v3:
- (rebased to svn r13552)
- coding style fixes
- Ssdt.asl: changed license to 2-clause BSDL, paraphrasing Dsdt.asl
retested for v3 (pci=nocrs never passed, efifb working):
