RESEND [Xen-unstable][Qemu-xen] HVM Guest reading of Expansion ROM from passthroughed PCI device returns data from emulated VGA rom
*RESEND* due to exceeding the mailinglists limit for attachment size.
Hi,
I''m trying to get secondary vga-passthrough on a HVM guest to work with a AMD HD6570 and the native kernel radeon driver and kernel modesetting.
So the guest still gets the emulated stdvga or cirrus device(used in my case here) as primary/boot vga adapter.
- When i don''t passthrough the radeon card, the

Hello everyone,
Reposting with after having applied the (minor) fixes suggested by Wei
and Jan.
Allen, if you can tell us what you think about this, or suggest someone
else to ask some feedback to, if you''re no longer involved with VT-d,
that would be great! :-)

[PATCH V2] x86/AMD-Vi: Add additional check for invalid special->handle
From: Suravee Suthikulpanit <suravee.suthikulpanit@amd.com>
This patch add an additional logic to check for the often case when the
special->handle is not initialized due to firmware bugs.
but the special->usedid is correct. If users overide this using the
command line option ivrs_ioapic, then it should use the value instead.

IOMMU and AMD 890fx
Hi,
All the reviews for the AMD 890fx chipset reported that it supports IOMMU
v1.2.
But I cannot find any mention of that on AMD site.
Does 890fx support IOMMU?
Do 890fx motherboards with IOMMU exist?
Does Xen support 890fx?
Regards,
Leonardo

[PATCH 1/1] keep iommu disabled until iommu_setup is called
The iommu is enabled by default when xen is booting and later disabled in
iommu_setup() when no iommu is present.
But under some circumstances iommu-code can be called before iommu_setup() is
processed. If there is no iommu available xen crashes.
This can happen for example when panic(...) is called that got introduced with
patch "x86-64: detect processors subject to AMD erratum #121 and

Marek,
Thanks for the detailed report! Can I trouble you to file a bug
at http://oss.oracle.com/bugzilla ... oh, is that your report
http://oss.oracle.com/bugzilla/show_bug.cgi?id=1339?
This looks like a deadlock of some sort. I don't think your
hardware configuration really matters here. We'll keep looking into it.

890FX AMD-Vi (IOMMU)
Hello,
I was hoping someone might be able to tell me why IOMMU does not seem to be found on my system. At the very least is there any way I can get more debug information in addition to adding iommu=verbose to the command line?

Hi Jan,
Attached patch dumps io page fault flags. The flags show the reason of
the fault and tell us if this is an unmapped interrupt fault or a DMA fault.

XEN 4.1 performance issue
Hi,
I migrate Xen4.0 to XEN4.1, and found XEN4.1 performance is not as good as 4.0.2. xm shutdown takes longer time, control thru libvirt take longer time, and since I''m testing PCI/VGA passthru, the "createdevice: pci" also take around 5~8 seconds comparing to 1 second in XEN4.0.2. below is my configuration, do you have any suggestions to make the performance better?

[xen-unstable] Commit 2ca9fbd739b8a72b16dd790d0fff7b75f5488fb8 AMD IOMMU: allocate IRTE entries instead of using a static mapping, makes dom0 boot process stall several times.
Hi Jan,
After commit 2ca9fbd739b8a72b16dd790d0fff7b75f5488fb8 AMD IOMMU: allocate IRTE entries instead of using a static mapping, booting dom0 stalls several times.
Sometimes this results in RCU stall warnings from the dom0 kernel, hitting the "any" key, on normal or serial console, makes the boot continue for a while but it stalls several times.
(It also stalls on shutdown BTW)
