...''s mask bit. While we can''t allow the latter, we can permit reads and simply drop write attempts, leveraging the already existing infrastructure introduced for dealing with AMD IOMMUs'' representation as PCI devices. This fixes an interrupt setup problem on a system where _CRS evaluation involved the above described BIOS/ACPI behavior, and is expected to also deal with a boot time crash of pv-ops Linux upon encountering the same kind of system.

...ace? It is. However, I wrote the example table to give a rough idea, but didn't investigate the feasibility. I now think it would be easier to not present the virtio-iommu as a LNRO0005 to the guest, but solely as the IORT node. Instead of a namespace path, the node would directly describe the _CRS content, which should be enough for the kernel to instantiate the device. I'll prototype something to understand the problem better and find which is easier to do. I'm busy preparing for conferences, so it might be two or three weeks.

Hey all, Just downloaded the new Xen 4.0 and ran Make xen Make tools Make stubdom Copied the new files from dist/install Im already running pv_ops 2.6.31.6 kernel. When I boot i get (XEN) Panic on CPU 0: (XEN) IO-APIC + timer doesn''t work! I have tried booting with noapic boot option but makes no difference. The system worked fine on 3.4.2 CPU is AMD.

Hi, we are currently working on getting windows working on your xen servers. but we are facing a severe problem where dom0 and all domus hang for 1-5 seconds from time to time. we think it is probably because of disk i/o, because top sometimes says 100% wa (waiting on io) during the hang. dom0 has cpu 0 for exclusive use and the windows vms use cpu 1 to 7. should we give dom0 more than once

Konrad, et al, I am seeing visual corruption (almost like an interlacing problem) with i915 under Xen on some platforms using linux-3.8. See attached file for an example of the visual corruption. This particular platform is an HP Elitebook 2540p The same kernel and ramdisk, when booted as native linux does not show this corruption. dmesg is attached, as well (out.txt) - but I did not see

Hello, I originally posted this to xen-users, but someone suggested I post it here. I am having ACPI problems on a PenguinComputing Altus1600 system. It has 2x dual core Opteron 2210 processors. The system boots with a standard Debian or Ubuntu SMP kernel, with ACPI enabled. However the xen live cd, binary xen install, as well as my own custom compile of xen 3.0.4 from source will not boot.

Hello, I have been working on VGA-passthrough in the last month. When Xen was at his version 3.5 there was a few patches to make this work for some graphic cards using the patches developed by Han Weidong and posted here (http://lists.xensource.com/archives/html/xen-devel/2009-08/msg01176.html) and the same patches posted file by file are here

Hi, I have been receiving messages on a new DomU''s kern.log. I''ve done a lot of googling, but haven''t came up with anything very useful, at least not in a Xen context. I was wondering if anyone had any suggestions about what could be wrong. From everything I have read, there should be a stack trace included, but I am not seeing one. Thanks in advance, Ian. on
