What amd motherboard supports iommu for video reasigment _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

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? Xen 4.0.0 MSI 890FXA-GD70 (I spoke with an MSI representative who confirmed that this motherboard does support IOMMU) AMD Phenom II 1090T x6 # dmesg __ __

I just wonder why xen 4.4 unstable presents it self as xen 4.3 unstable ? boot message states 4.3 unstable and efi is 4.3 unstable? I wonder what is the reason behind it ? _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

Hi, I''m running a machine with: - Hypervisor: xen-unstable - Dom0: xen/next-2.6.32.17 commit c3f5aba942c7516a5c76c47345ff0a473daf2542 Hardware: -MSI 890FXA-GD70 with AMD IOMMU -Phenom X6 I''m trying to do PCI passthrough to a HVM, this fails with: Error: Failed to assign device to IOMMU (0000:04:00.0@100,msitranslate=1,power_mgmt=0) Error: pci: to avoid potential security

Changeset 20514 implemented deallocation for msi interrupt remapping entries. Attached patch adds the same support for amd iommu to fix a xen crash on amd iommu systems.

Hi all I have a problem with enabling IOMMU on Xen 4.2.1. When I enable it in BIOS and in grub.conf using iommu=1 kernel option, my machine cannot boot. I get a following error on serial console: (XEN) **************************************** (XEN) Panic on CPU 0: (XEN) Xen BUG at pci_amd_iommu.c:35 (XEN) **************************************** (XEN) (XEN) Reboot in five seconds... Error says

Did something had chaqnged with spice code or settings. I just compiled latest git of 4.4 unstable and I get is a black screen all I see is the green boot image from server 2012 but I dont get blue windows logo and window does not resize it stays black. I reverted back to older git revision of 4.4 and everything is working fine with. _______________________________________________ Xen-users

Tom, next time please cc Jerg as the AMD IOMMU maintainer. Joerg, any chance you could review this? Toms patches to convert the AMD and Intel IOMMU drivers to the dma-iommu code are going to make my life in DMA land significantly easier, so I have a vested interest in this series moving forward :)

Hi Christoph, I quit my job and am having a great time traveling South East Asia. I definitely don't want this work to go to waste and I hope to repost it later this week but I can't guarantee it. Let me know if you need this urgently. Thanks, Tom On Sat 10 Aug 2019, 3:20 p.m. Christoph Hellwig, <hch at infradead.org> wrote: > On Sun, Jun 23, 2019 at 11:19:45PM -0700,

I have few instance of server 2008 running on xen. i want to configure them to redirect sound.

Hi all! I've just recently noticed these lines in the dmesg output: Please enable the IOMMU option in the BIOS setup This costs you 64 MB of RAM they may have been there forever, but I never noticed them before. This system is an AMD Phenom-II X2 CPU on a Gigabyte MA770-UD3 motherboard. I have no idea which BIOS option I need to change to solve this, I see nothing in the setup that
