...es. I tested passtrough with: - the onboard (fake-)raid-controller (no problems) - a pci card (no problems) - VGA cards (worked only partly - I''ll investigate that) I wrote a little patch to the code parsing the RMRR tables and enabled the following command line options: iommu=passtrough iommu_inclusive_mapping=1 As an attachment, I created a full patch which enables those command line options by default and can be directly applied to XEN 4.0.0. However, this patch is *not* intended to be merged to the unstable versions and I''ll discuss an appropriate patch on xen-devel. This patch is only for...

OK, cut two of the iommu reserved memory issue patch as we discussed... This patch adds a boolean boot parameter to xen to allow inclusive mapping of all memory below 4GB to the iommu mappings for dom0. The unusable ranges and memory occupied by xen are still excluded. The parameter is "iommu_inclusive_mapping=1" and is off by default. In addition to the parameter, a warning is also traced when incorrect RMRR to system memory map values are detected. These are being added to address some incorrect BIOS''s that do not report correctly the requied reserved memory ranges in the RMRRs. When this...

If there is no option to configure the buffer size then at the very least should''nt it be set big enough to h...

Hi, I just upgraded to the latest SID after reinstalling my test server. Then, after a while, during the boot process, Xen seems to hang, then my server reboots. It's difficult for me to see anything, since I'm using a KVM over IP, using a quite slow link (from China to UK, using a FreeNX box that connects through a Java KVM over IP to the server), and I don't think it'd be easy

Hello, It looks like upstream linux-2.6.git contains at least the following xen related new features for Linux 2.6.36: - Xen-SWIOTLB support (required for Xen PCI passthru and dom0) - Xen PV-on-HVM drivers - Xen VBD online dynamic resize of guest disks (xvd*) Congratulations! What are the plans for 2.6.37 merge window? I believe at least: - Xen PCI frontend Others? I''m going to

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
