similar to: [PATCH][VTD][GFX] pass gfx_passthru parameter to QEMU

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

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.

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.

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) -

vtd: Fix for irq bind failure after PCI attaching 32 times Originally when detaching a PCI device, pirq_to_emuirq and pirq_to_irq are freed via hypercall do_physdev_op. Now in function pt_irq_destroy_bind_vtd, duplicated logic is added to free pirq_to_emuirq, but not pirq_to_irq. This causes do_physdev_op fail to free both emuirq and irq. After attaching a PCI device for 32 times, irq resources

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

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

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

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

Hi, Keir, This patch will move reading and writing of PCI configuration spaces from dom0 to Xen. It also changes VTD code, so that they can touch the PCI configuration spaces with proper lock. This will also benefit MSI support in Xen. Can you give some comments? Thanks! <<pci_conf_xen.patch>> Best Regards Haitao Shan _______________________________________________ Xen-devel

Hi, How come gfx_passthru is now an invalid option? Does it mean Xen-unstable 4.4 changeset 27214 no longer supports vga passthrough? -- Yours sincerely, Singapore Citizen Mr. Teo En Ming (Zhang Enming)

Platform : Nehalem, official Intel x58 with Core i7 920 (dx58so) Main (Console): Nvidia 9500 GT PCI Express Secondary: Nvidia 8800 GTS PCI Express Yes, I binned the ASUS P6T due to bad VT-d support in the BIOS. With the latest BIOS from Intel, the dx58so has enable/disable for VT-d, ICH FLR and Interrupt Mapping! Helped a lot with getting this working ... Dom0: 2.6.18-xen0 (built from

Greetings, I''m attempting to do gfx_passthru with the primary graphics adapter (03:00.0), passing it to a guest. I can unbind it from the host but when I fire up the guest OS my monitor loses signal from the graphics card and that''s that. The GFX card is dual DVI, I''ve tried both slots. Host is Linux 2.6.32.14-1.2.105.xendom0.fc12.x86_64, Guest is Windows 7. PC is an

Hi, to use the host keyboard and touchpad of my laptop while running a HVM guest with passthroughed primary gfx-card I wrote a simple emulation. To activate it change gfx_passthru=1 -> gfx_passthru=1001 in the domU config file. This was done this way to have a small footprint. Also the embedding in helper2.c is a little bit awkward. Another problem using this way is that the VT in dom0 is not

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

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
