Subject: RE: [Xen-devel] graphics passthrough with VT-d
Teo,
I attached some experimental patches for you to try to sthorugh Geforce 8400 GS.
Based on my patches posted last Friday, pls follow below instructions:
1. apply xen-load-vbios-file.patch to xen-unstable.hg
this patch supports to load vga bios from a file.
2. apply xen-vBAR-pBAR.patch to xen-unstable.hg
this patch is used to 1:1 map between vBAR and pBAR
3. apply qemu-change-for-vBAR-pBAR.patch to ioemu-remote (qemu tree).
this patch is used to 1:1 map between vBAR and pBAR on qemu side
4. apply qemu-claim-cycle-for-secondary-gfx-passthrough.patch
it''s needed if you want to assign the secondary gfx to guest.
5. cd xen-unstable.hg
6. make clean
7. copy the vga bios file to
xen-unstabl.hg/tools/firmware/vgabios/vgabios-pt.bin
8. make; make install
9. reboot the system. or xend restart. then passthrough gfx to guest ...
Regards,
Weidong

Hi Timothy,
Yes, I renamed the firmware file of nVidia Geforce 8400 GS to vgabios-pt.bin and
placed it in the source directory tools/firmware/vgabios.
Weidong had said Intel has the 1:1 mapping patches. Let''s hope he will
release the patch soon to do pBAR:vBAR.

Teo,
Did you rename your Nvidia BIOS and copy it into the hvmloader source tree as
required ?
It should get compiled into roms.h in the hvmloader folder - I made sure it was
there as the xen buildroot seems to delete it randomly ...
I think we are now up against the Base Address Register issue where the Nvidia
driver is expecting to see the card at the Physical BAR Addresses and in the
DomU these are re-mapped to different address space ... this is a problem with
the Nvidia binary driver and therefore a workaround in xen is maybe needed.
That said, I''m not sure if the Nvidia BIOS likes to be re-executed and
may also be an issue ...

Subject: Re: [Xen-devel] graphics passthrough with VT-d
Dear All,
I have applied the following patches to xen 3.5-unstable
1) intel-gfx-passthru-patch01.patch
2) intel-gfx-passthru-patch02.patch
3) intel-gfx-passthru-patch03.patch
4) enming-patch04.patch
and compiled xen 3.5-unstable successfully (both hypervisor and tools).
i rebooted into this newly compiled Xen hypervisor which supports loading vga
bios from firmware file of nVidia Geforce 8400 GS PCI Express x16.
After dom0 has booted up, I executed the following script to hide nVidia Geforce
8400 GS from dom0.
[enming@fedora11-x86-64-host scripts]$ cat bind-devices-pci-stub.sh
#!/bin/sh
echo "10de 06e4" > /sys/bus/pci/drivers/pci-stub/new_id
echo "0000:01:00.0" >
/sys/bus/pci/devices/0000:01:00.0/driver/unbind
echo "0000:01:00.0" > /sys/bus/pci/drivers/pci-stub/bind
I also assigned the nVidia Geforce 8400 GS to my Windows XP Home HVM domU.
pci = [ ''01:00.0'' ]
I also specified gfx_passthru=2.
Do note that I booted up with onboard Intel GMA4500 as the primary video
adapter. Hence dom 0 has onboard graphics and Windows XP HVM domU has nvidia
graphics.
Then I started Windows XP Home HVM DomU.
Very soon, my Dom 0''s display was garbaged and X server on Dom 0
totally froze and became unresponsive. I cannot switch to any ttys.
However, I was still able to vnc into my Windows XP Home HVM Dom U. I had
earlier installed a VNC server into my Windows XP guest. After remoting in to my
Windows XP DomU through vnc, I found that NVIDIA Geforce 8400 GS cannot be
initialized and no resources are available for this graphics card.

Hi All,
I have solved the problem encountered below when building tools for xen
3.5-unstable. The compile problem exists because I downloaded and compiled the
latest version of Intel ACPI Component Architecture compiler version 20090730.
And I used this latest compiler during "make tools" for xen-unstable.
In original xen-unstable source codes cloned from xensoure mercurial repository,
the header files ssdt_pm.h and ssdt_tpm.h in source directory
tools/firmware/hvmloader/acpi/ are generated by
/*

*
* Compilation of "ssdt_pm.asl" - Sun Oct 12 23:57:51 2008
*
* C source code output
*
*/
In original ssdt_pm.h, it has "unsigned char AmlCode_PM[] =".
In original ssdt_tpm.h, it has "unsigned char AmlCode_TPM[] =".
Hence there was no problem with "make tools".
But, I downloaded, compiled and used

So the *new* ssdt_pm.h contains:

which are both wrong.
In ssdt_pm.h, I have to change "unsigned char AmlCode[]" to
"unsigned char AmlCode_PM[]".
In ssdt_tpm.h, I have to change "unsigned char AmlCode[]" to
"unsigned char AmlCode_TPM[]".
Then "make tools" is able to complete successfully.
I have created a patch for anybody who may be using the *latest* version of
Intel ACPI CA compiler version 20090730 and attached it here.

There is an undeclared identifier in tools/firmware/hvmloader/acpi/build.c
source code. Could you guys help me resolve this issue?
I had no problems compiling xen 3.5-unstable before applying the Intel vga
passthrough patches and before installing the Intel ACPI Component Architecture
compiler.
I have also attached Intel graphics passthrough patches 1, 2 and 3 for your
convenience here.
Thank you very much.
Hope I can get this working during the weekends.

Hi Tim,
I thought it should be gfx_passthru=2 in domU config?

Teo,
I have also performed the same exercise as yourself and I now have successfully
compiled all 3x patches into Xen, Qemu and the BIOS File Loading in the
hvmloader, this all compiles find on my system. Suggest you do a "make
clean" on the tools and start again !
After booting with the patched xen-unstable and adding the gfx-passthru=1
parameter to my HVM DomU, as I suspected - it still doesn''t work.
I have both a 9500GT and GTX260(primary) in my Intel DX58SO machine, tried
passing through either device and my primary display locks up ! (included hiding
with pci-stub)
I verified that the DomU was functional beforehand, as It also booted
successfully without the gfx-passthru parameter (and a vncviewer/cirrus display)
Unfortunately, I can''t debug further as my Primary display corrupts as
soon as the DomU starts. I did notice that in "xm debug" the
"Loading Gfx BIOS File.." message was displayed and the DomU did
continue to initialise the BIOS tables and such before finally locking. I then
(blindly) typed on a corrupt Dom0 console and managed to start kdm and login, so
the Dom0 was not completely trashed. But then after a few minutes, the machine
totally froze and had to hit the reset switch.
I`m no specialist but this looks like the VGA BIOS Re-initialisation is playing
havoc with the DomU and possibly the Dom0 graphics. I notice that both are also
using IRQ11 which could play a major part. Furthermore, there was a lot of debug
output in the qemu and xend.log indicating Base Address Register invalid access
and therefore it seems there may be a second obstacle.
Hope you have a better success than me !
For now, I would try re-compiling a fresh xen-unstable with carefully applied
patches .. oh! and don''t forget to enable the pci-stub driver for Dom0
(it''s not selected by default)

Subject: Re: [Xen-devel] [PATCH 2/2] graphics passthrough with VT-d
After applying the 1st and 2nd patch to xen-unstable successfully, I examined
the source codes Makefile and hvmloader.c in tools/firmware/hvmloader, compared
them to Weidong''s 3rd patch and I generated my own 3rd patch. Then I
used my own generated 3rd patch to apply patching for loading vga bios from
firmware file.
Here is my own generated 3rd patch instead of using Weidong''s 3rd
patch:

I can "make xen" successfully but when I proceeded to "make
tools", errors were encountered.
Please see attached error output. How can I solve this problem?

Dear Weidong,
A big big thanks for the vga passthrough patches for xen 3.5-unstable!!! These

I applied the following patches
