Subject: [PATCH] switch stdvga to pci vgabios
Make stdvga provide the new vgabios binary (with pcibios support)
using the PCI option rom bar. Seabios will happily load it from
there. The new vga bios will also lookup the framebuffer address
in pci config space, so the magic bochs lfb @ 0xe0000000 is not
needed any more -> zap it.
Without the patch:
# dmesg | grep framebuffer
vesafb: framebuffer at 0xe0000000, mapped to 0xf7e80000, using 1875k, total 8192k
# lspci -vs2
00:02.0 VGA compatible controller: Technical Corp. Device 1111 (prog-if 00 [VGA controller])
Subsystem: Qumranet, Inc. Device 1100
Physical Slot: 2
Flags: fast devsel
Memory at f0000000 (32-bit, prefetchable) [size=8M]
Expansion ROM at <unassigned> [disabled]
With patch applied:
# dmesg | grep framebuffer
vesafb: framebuffer at 0xf0000000, mapped to 0xf7e80000, using 1875k, total 8192k
# lspci -vs2

cheers,
