Hi,
This patch series updates the vgabios git tree at
git://git.qemu.org/vgabios.git to vgabios v0.6c.
Patches are creates using 'git cvsimport' with some cleanups afterwards:
drop binary updates, drop cvs $Id$ changes from commits. Replace
'vruppert' with Volkers real name.
Note that vgabios v0.6c depends on a newer revision of the bochs vbe
interface which is only supported in the qemu devel versions but not in
the 0.12.x stable branch.
please apply,
Gerd
Volker Ruppert (5):
- use VBE LFB address from PCI base address if present (rewrite of
the cirrus specific function in main vgabios code) - removed
unnecessary spaces
- added support for a lot more non-standard VBE modes (e.g.
widescreen modes) - requires latest Bochs VBE code (16 MB video
memory, VBE_DISPI_ID5, VRAM size in 64k pages stored in VBE
register) - check if VBE mode is supported with current VRAM size
- preparing for release 0.6c
- biosfn_write_teletype: fixed attribute when scrolling in text mode
- updates for release 0.6c
