GFX Passthrough
...o that i have alsa-backed sound emulation , for some reason
i have only oss-backed if not applied ?!)
Before all that, you need to read out the VGA Bios of the to-be-passthroughed-
Graphiccard with a tool; i used nvflash.exe under DOS for this task.
The patches assume you saved this file as "vgabios-pt.bin"
1. check out xen unstable:
hg clone http://xenbits.xensource.com/xen-unstable.hg
2. go into there and do an "initial build" so that qemu-dm gets checked-out:

Improving xen-qemu-dm-4.0 dependencies
Hi,
When I first built my Debian package, I needed to depend on qemu-system
| qemu, since there was no other ways to pull needed BIOS files.
It seems the situation changed, and that I could depend on less stuff
from the qemu package. Maybe only the package named "etherboot" and
"vgabios". To do that, my plan is to simply package a folder named:
/usr/share/xen/qemu
with in it symlinks, in a similar way of what you can find in
/usr/share/qemu
So, my question is simple. Out of this, what do I need for xen-qemu-dm?

[PATCH v2 0/3] hvmloader: Make ROM dependencies optional
This patch set mainly allows the user to build a seabios or rombios only
version of hvmloader.
In addition, when building a seabios only hvmloader, Option ROMs like

from the build. Dependency on the bcc compiler can also be avoided the

A question on vmx loader in xen - how and when rombios is loaded into memory
A "main" function is defined in
Xen-3.1.0-source/tools/firmware/hvmloader/hvmloader.c.
In this main function, rombios, vgabios and vmxassist are copied to
specified address,
with following commands
memcpy((void *)ROMBIOS_PHYSICAL_ADDRESS, rombios, rombios_sz);

They are statically compiled into hvmloader in the way of C array and are loaded with hvmloader.
Please step into the directory hvmloader/ and search for "roms.h" in Makefile.

[PATCH] Add virtio gpu driver.

The virtio-gpu driver doesn't matter much here, it doesn't use it
anyway.

Yes, vgabios code needs to know. Currently it has bar #2 for the vga
framebuffer bar hardcoded. It's 16bit code. I don't feel like making
the probing more complicated ...
