similar to: [PATCH] qemu-xen: Intel GPU passthrough, fix OpRegion mapping.

This is hvmloader part of the change that gets rid of the resource conflict warning in the guest kernel. The OpRegion may not always be page aligned. As a result one extra page is required to fully accommodate the OpRegion in that case. Just reserve one more page here.

Userspace patches for the pci-passthrough functionality. The major updates since the last post are: - Loop to add passthrough devices in pc_init1 - Handle errors in read/write calls - Allow invocation without irq number for in-kernel irqchip Other than this, several small things were fixed according to review comments received last time.

hi, I want to pass through "01:00.0",declared as pci=['01:00.0'] in cfg file. but found error log "pt_iomul_init: Error: pt_iomul_init can't open file /dev/xen/pci_iomul: No such file or directory: 0x1:0x0.0x0". in qemu-dm-example.hvm.log In fact, /dev/xen/pci_iomul does not exist. So where /dev/xen/pci_iomul implemented ? I have searched xen and linux code,

This series contains all the fixes required to produce a working IGD passthrough box. All the changes are previously seen in the dev list but not yet accepted. Some of them are out-dated and need some reshape. Detailed description can be found later in each patch. . [PATCH 1/3] qemu-xen-trad/pt_msi_disable: do not clear all MSI flags . [PATCH 2/3] qemu-xen-trad: Correctly expose PCH ISA bridge

This is a way to create virtio based devices from user space. This is the background for this patch: We have some images works fine under qemu, we'd like to also run the same image on Google Cloud. Currently Google Cloud doesn't support virtio-vga. I had a patch to create a virtio-vga from kernel directly: https://www.spinics.net/lists/dri-devel/msg248573.html Then I got feedback from

Using Xen 4.2 unstable rev. 25483. I get errors like this: pt_pci_read_config: [00:10:0] Error: Failed to read register with offset exceeding FFh. [Offset:ffh][Length:1] in my qemu log for a domU with some devices passed through to it. I investigated and found that at hw/pass-through.c line 1717

Hi developers, I met some domU issues and the log suggests missing interrupt. Details from here: http://www.gossamer-threads.com/lists/xen/users/263938#263938 In summary, this is the suspicious log: (XEN) vmsi.c:122:d32767 Unsupported delivery mode 3 I''ve checked the code in question and found that mode 3 is an ''reserved_1'' mode. I want to trace down the source of this

Hi List, many People seem to be interested in the Graphic-Card Passthrough Feature (for more or less obvious reasons). Official Support is still under development, and i hope not to interfere with it in any (bad) way ... But i remember my own painfull and timeconsuming research when i wanted this feature to work, so i thought perhaps this spares some time for the unpatient users like me :)

Hi, everyone! I am working on xen-4.2.0 with spice remote connect. My host is Fedora 14 and guest is win7. I have installed spice package and now I can connect to guest by spice client. For better graphics experience, I want to try the VGA passthrough. With spice tool, I have to create a VM by xl command, and now I am wondering if it supports VGA passghrouth? If so, how should I test it ?

This fixes a few things that I missed in previous patches: * Use the hw INTX rather than INTA in pt_reset_interrupt_and_io_mapping() This is consistent with other uses of pci_intx() * Remove now inaccurate "/* fix virtual interrupt pin to INTA# */" comments * Use PCI_SLOT() Signed-off-by: Simon Horman <horms@verge.net.au> Index: ioemu-remote/hw/pass-through.c

The i915 driver probes chip version through PCH ISA bridge device / vendor ID. Previously, the PCH ISA bridge is exposed as PCI-PCI bridge in qemu-xen-trad, which breaks the assumption of the driver. This change fixes the issue by correctly exposing the ISA bridge to domU. Signed-off-by: Rui Guo <firemeteor@users.sourceforge.net> Tested-by: Rui Guo <firemeteor@users.sourceforge.net>

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

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
