RE: [Xen-devel] [PATCH 2/2 v2] graphics passthrough with VT-d

I have checked out xen 3.5-unstable changeset 20143 and applied all the vga passthrough patches.

But nVidia Geforce 8400 gs pci-e x16 passthrough to win xp home hvm domU on my Intel dq45cb still doesn’t work.

I am shown the qemu monitor. I can only switch between the qemu monitor and the parallel0 console. I can’t see win xp home hvm domU booting.

Anybody has success with vga passthrough to win xp hvm?

Yes. so you can use old xen version.

BTW, our patches only changes tools and qemu code, doesn't change xen hypervisor code, so you just need to 'make tools' and 'make install-tools'.

Hi,

I have read the man page for hg.

To check out changeset 20143, just run

# hg checkout 20143

Hi,

If I checked out 20145 or later, then I need to SKIP xen-gfx-passthrough.patch but apply all the rest of the patches?

If I cannot do this, how I can check out earlier changesets? Is it hg checkout something something?

My patching procedures are:

# cd xen-unstable.hg

# patch –p1 < xen-gfx-passthrough.patch

# cd tools/ioemu-remote

# patch -p1 < qemu-gfx-passthrough.patch

# cd ../..

# patch -p1 < xen-load-vbios-file.patch

# patch -p1 < xen-vBAR-pBAR.patch

# cd tools/ioemu-remote

# patch -p1 < qemu-change-for-vBAR-pBAR.patch

# patch -p1 < qemu-claim-vga-cycle-for-secondary-gfx-passthrough.patch

# cd ../..

# make clean

copy vgabios-pt.bin to tools/firmware/vgabios

# make xen

# make install-xen

# make tools

# make install-tools

# reboot

Thank you.

make sure your xen version is older than 20144, such as 20143. Otherwise it conflicts when you apply my posted patches.

Pls post your steps to build your environment with my patches. I suspect you may make some mistakes on xen build.

Hi Weidong,

Even though I tried to apply xen-gfx-passthrough.patch to xen 3.5-unstable changeset 20145, it asked “Apply anyway?” and I chose no. For assume –R, I also chose no. Some files have been patched, while most files are not patched with xen-gfx-passthrough.patch.

xen-gfx-passthrough.patch was checked into xne-unstable as changeset 20144,so you cannot apply it on 20145.

For your secondary gfx passthrough case, pls use the version 1 patches. Christian Tramnitz said he succeeded to passthrough secondary gfx with my patches.

Weidong

Dear Weidong,

I checked out xen 3.5-unstable changeset 20145.

I applied xen-gfx-passthrough.patch to changeset 20145.

There were some errors with

Reversed (or previously applied) patch detected! Assume -R

So I think the maintainers of xen-unstable had applied some of the patches from xen-gfx-passthrough.patch you posted to the tree.

Then I applied the rest of the patches:

qemu-gfx-passthrough.patch
xen-load-vbios-file.patch
xen-vBAR-pBAR.patch
qemu-change-for-vBAR-pBAR.patch
qemu-claim-vga-cycle-for-secondary-gfx-passthrough.patch

to changeset 20145 without problems.

Here are the test results. Note that all of the test results are based on starting Windows XP Home HVM domU while in X server on dom0.

If I try to start domU in text mode on dom0 (without X server), then the screen output will be garbaged and I won't be able to type anything at all in dom0 text mode.

I switched to vcpu=2 for win xp home hvm domU. Now domU does not crash. xm list shows domU running. But vncviewer pops up a QEMU monitor. Looks like win xp home hvm domU did not start. All I get is a QEMU monitor.

Hope the test results helped.

I can start win xp home hvm dom U successfully if i remove pci in domU config and set gfx-passthru=0, basically starting with emulated vga bios instead of passing through pci-e graphics.

Hi,

How about the patch for loading vga bios from .bin file and the 1:1

bar mapping in version 2 release?

Let's make the basic patches better and acceptable first. I haven't rebased

the hacks patches on version 2 patches. Currently pls use the hack patches

with version 1 patches.

Regards,

Weidong

Thanks for the version 2.

Subject: [Xen-devel] [PATCH 2/2 v2] graphics passthrough with VT-d

This patch supports basic gfx passthrough on QEMU:

  - disable emulated VGA adpater if there is passthroughed gfx

  - retrieve VGA bios from host 0xC0000, then load it to guest 0xC0000

  - register/unregister legacy VGA I/O ports and MMIOs for

passthroughed gfx
