Pass-through a graphic card
PATCH 1/1 Pass-through a graphic card
Hi folk,
This patch is for pass-through the principal graphic card to a hvm guest.
This is what is done inside :
- We map the VGA frame buffer into the guest's memory (0xa0000 ->0xbffff)
- We get the vga bios address from /dev/iomem and we put it at the
end of hvmloader. Etherboot has been moved to 0xD0000 to let enough space to load the dom0 vgabios (it could be pretty big).
- Map the vga ioport using /dev/ioports.
- We disable the vga code into xen, hvm.c:313
- Then we start qemu with the new option -enable-dom0 to have the
dom0's keyboard and the mouse redirected into the guest.
This patch work only with the principal graphic card and you must have a box with vt-d.

Here an example of how to enable the feature :
--------------
kernel = "/usr/lib/xen/boot/hvmloader" builder='hvm'
memory = 512
name = "winxp"
vif=[ 'type=ioemu,bridge=eth0,mac=00:16:3E:2E:26:BE' ] disk=['file:/mnt/img/winxp/disk.img,ioemu:hda,w'] boot="c"
vnc=0
timer_mode=2
pci = [ '0a:01.0' ]vga_pass through=1
--------------
Be careful, vnc must be at 0. 0a:01.0 is the pci id of my graphic card, of course it must be hide with pciback.
Thanks for your comments.

Be careful, vnc must be at 0.
Can't you have the dom0 option override the vnc option?

Here, a new patch with the modifications that Samuel suggested.
Could you adjust your mail client so it attaches patches as text/plain or include them inline to the body. Using text/xdiff means that many mail clients won't quote the patch when replying making sending patch feedback really much more difficult / convoluted
Regards,
Daniel.

Hi,
Here a new version of the vga pass through patch.
The HVM_PARAM was removed, in that way this patch doesn't change anything in the hypervisor.
This patch has to be applied instead the previous one.
Thanks to all people who have tried this experimental patch by them self. Please continue to send my your feedback.
---
This patch is for pass-through the principal graphic card to a hvm guest.
This is what is done inside :
- We map the VGA frame buffer into the guest's memory (0xa0000 ->0xbffff)
- We get the vga bios address from /dev/iomem and we put it at the
end of hvmloader. Etherboot has been moved to 0xD0000 to let enough space to load the dom0 vgabios (it could be pretty big).
- Map the vga ioport using /dev/ioports.
- Then we start qemu with the new option -enable-dom0 to have the
dom0's keyboard and the mouse redirected into the guest.

Yes, but it doesn't really matter. I am rewriting the patch to not use this thing any more.

I new version (again). Here the change for this version :
- No more modification of the hvm_info_table.
- Creatation of a SCRATCH zone for hvmloader : 0x1000.
- Copy directly the VGABIOS at the right place (0xC0000) into the
guest memory.
- Detect which graphic card are present in pci_setup().
- Remove the function cirrus_check
- Add the support for some special keys for the dom0 driver.
---
This patch is for pass-through the principal graphic card to a hvm guest.
This is what is done inside :
- We map the VGA frame buffer into the guest's memory (0xa0000 ->0xbffff)
- We get the vga bios address into the guest memory. Etherboot has
been moved to 0xD0000 to let enough space to load the dom0 vgabios (it could be pretty big).
- Map the vga ioport 0x03c0 -> 0x03df.
- Then we start qemu with the new option -dom0-driver to have the
dom0's keyboard and the mouse redirected into the guest.
