Xen users - Aug 2011 - Pathcs for VGA PassThrough for xen-4.2 unstable revision 23799

Hi

I''ve just updated the patchs taken from mailing list on May 2011.

As usual

hg clone -r 23799 http://xenbits.xensource.com/hg/staging/xen-unstable.hg/ xen
# Make a first "init build"
cd xen/tools
make 
make clean
cd ..

# Download patches and patch
wget -q http://www.davidgis.fr/download/gfx_patch.tar.bz2
tar xvjf gfx_patch.tar.bz2 
for file in $(ls gfx_patch/*.patch);do patch -p0 < ../$file;done

# Copy the bios (EEPROM) of your graphic card to 
#tools/firmware/vgabios/vgabios-pt.bin
cp /path/to/yourbios.rom tools/firmware/vgabios/vgabios-pt.bin

# Compil and install

Updating tools/firmware/hvmloader/acpi/dsdt.asl
################################################
Notice: I''ve updated the file tools/firmware/hvmloader/acpi/dsdt.asl
for my graphic card (MSI GT 440 1024), so please update the file
tools/firmware/hvmloader/acpi/dsdt.asl according to the required memory
reservations
of your graphics card.

Get it using lspci |grep VGA. Ensure to use

dmesg | grep pci (depends of required modules for PCI debug in your kernel

Find the required fields

Update the file.

I did not succeed to use my graphic card EVGA GTX 460 1024M. If someone
succeeded, it will be
great to tell how he did :)

I''m going to passthru my GTX460 1024Mb and I''d like you to
send me the patch
for xen 4.2. I tried to edit your patch myself but got errors during xen
compilation. Thanks!

Hi

What kind of error did you get?
I tried to follow the instruction and the only fault I had was in the 
Makefile. I guess the patch should be as included below.
