Hi Tim, Could you please have a look at this bug? Thanks a lot. http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1774 Best Regards, Yongjie Ren (Jay) _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi list, I have a problem with a new laptop (reproducable on other machines too) and the xen hypervisor. When the hypervisor gets booted with VESA mode 800x600 I see some messages and then the screen contents is switched into a pattern of vertical colored lines and never comes back. In text mode all works well, but later the pattern appears when the X servers starts. I disabled VTd in the bios

The following 5 patches are re-submissions of the vt-d patch. This set of patches has been tested against cs# 15080 and is now much more mature and tested against more environments than the original patch. Specifically, we have successfully tested the patch with following environements: - 32/64-bit Linux HVM guest - 32-bit Windows XP/Vista (64-bit should work but did not test) -

hi, This is what I get on the Intel DQ35JO. Is it critical?

All, We met several system failures on different hardware platforms, which are all caused by VT-d fault. err 1: disk is corrupted by VT-d fault on SATA. err 2: Dom0 kernel panics at booting, which is caused VT-d fault on UHCI. err 3, Dom0 complains disk errors while creating HVM guests. The culprit would be changeset 19054 "x86_64: Remove statically-partitioned Xen heap.". Detailed

I assigned FC-HBA to guest domain, but it did not work. FC-HBA seems to write its internal memory which is mapped to host memory space via pci transaction. But there is no mapping in IOMMU''s page table, so that page fault occurs in IOMMU. I think that MMIO resource mapped via p2m table should be mapped via IOMMU''s page table too. In other word, XEN_DOMCTL_memory_mapping

Hi, I''ve added some preliminary support for VT-d for paravirtualized guests. This must be enabled using an ''iommu_pv'' boot parameter (disabled by default). I''ve added some python bindigs to allow xend to assign PCI devices to IOMMU for PV guests. For HVM guests this is handled in ioemu. Not sure if it makes sense to handle both cases in one place. The

The memory relating guest domain should be allocated from NUMA node on which the guest runs. Because the latency of the same NUMA node is faster than that of a different one. This patch fixes memory allocation for Address Translation Structure of VT-d. VT-d uses two types of Structures for DMA address translation. The one is Device Assignment Structure. The other is Address Translation

Hello, I have been working sometime now on getting a HVM accepting a PCI card from the host. As was said in the VT-D wiki I bought an ASUS P5E VM DO motherboard (rel 0803) which has the VT-D option in the bios. I want to pass a Hauppauge PVR 500 card to a virtual machine running LinuxMCE. After first trying XEN 3.2.1 which did not enable the "VT-D virtualisation" bit in xm dmesg, i

The patch deals with the situation which guest OS uses unused page table pages as data pages and write data to them. The pages will still be grabbed by Xen as page table pages, and lots of unnecessary page faults occur. The patch will check if the data guest writes to the page table contains valid mfn or not, if not, we believe it is a data page now and then unshadow the page. The patch

Hello XCI developers, I have a HP6930, downloaded xenclient from the git. And by following the instruction in HOWTO, I could get xenclient boot up fine. I try then to start a guest using xenvm.readme as template and nothing shows on the screen for the guest, although xenops shows 2 doms running. Can you point me to how to start a guest. And also, is the tree downloaded from git enough to arrive

Fixes made in version 2: 1) Use PML4[257] for ioremap of PCI mmcfg. As full 16-bit segment support would require 44-bits. Since each slot only has 39-bits, we support 2048 PCI segments for now. This can be easily expanded if deemed necessary in the future. 2) Integrated PCI mmcfg access with existing PCI config interface for x86_64. Use MMCFG interface if offset is greater than 256.

Hi Ian, There have been a lot of interest on gfx passthru recently. This patch enables ATI VBIOS in passthru mode. The guest VM system BIOS (including Windows boot logo) can now show in passthru screen. We have tested with various Windows and Linux guest VMs. Please help review it. We are also looking forward to comments and suggestions from Xen community users. Signed-off-by: Wei Huang

hi, I am trying the Xen unstable on X48 chipset these days but it failed due to an corrupted RMRR table in the ACPI. The following is the acpi dump of DMAR.

Like others on this list I am trying to employ the VTD-NEO patches in Xen 3.2 unstable to assign the internal graphics device to Dom1/Vista. I have removed the Cirrus Logic emulated device from qemu and replaced the Cirrus Logic vgabios with the the actual vgabios from my GPU. However I am hitting an xen assert and was hoping someone might be able to point me in the right direction. Below

On Xen-3.3.0, domain0 Megaraid SAS (SAS 1068 controller) driver is not loading correctly if vtd support in Xen is enabled. It fails at the point of initializing firmware. I wasn''t seeing this error with Xen-3.2.2-rc3 (Unstable version), though with vtd disabled in Xen-3.3.0, it is working. Looks like a degrade problem. Any clues? Thx, Venkat

Pass gfx_passthru parameter to QEMU. Keep it boolean for now as QEMU does not expect any other integer value. Signed-off-by: Allen Kay <allen.m.kay@intel.com> _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Attached is a patch for shared interrupt between dom0 and HVM domain for vtd. Most of problem is caused by that we should inject interrupt to both domains and the physical interrupt deassertion then may be delayed by the device assigned to the HVM. The patch adds a timer, and the time out value is sufficient large to tolerant the delaying used to wait for the physical interrupt deassertion.
