similar to: Quadrified GTX 480 VT-d passthrough. CUDA 5.5 in Linux partial success

Hi everyone, after following in the footsteps of the following discussion (http://lists.xenproject.org/archives/html/xen-users/2013-09/msg00106.html) I had been able to turn my GTX 480 into a Quadro 6000. When I VT-d passthrough it to a Debian jessie VM it shows up fine and CUDA 5.5 seems to function properly up to a point: lspci -v: 00:04.0 VGA compatible controller: NVIDIA Corporation GF100GL

Hi everyone, First post, already a call for help :) I''m trying to use a gtx 580 with Xen 4 VGA Passthrough to test CUDA performances, the MB is an Asus P7P55 LX with a i7 870, VT-D is enabled in bios and reported as active by Xen. I''m using Debian Squeeze as Dom0 and DomU OS. Dom0 is configured with iommu=1 and iommu=verbose parameters and xen-pciback.hide=(01:00.0)(01:00.1)

Hi, My Windows 8 Enterprise HVM domU configuration is as follows. I have to *disable* gfx_passthru, that is, gfx_passthru=0. Please take note. # XL domain configuration file for Windows 8 64-bit English HVM domU # Please refer to "man xl.cfg" for further explanations. # See also docs/misc/xl-network-configuration.markdown and # docs/misc/xl-disk-configuration.txt # Written by Teo En

The hypervisor side changes for XSA-46 require the tool stack to now always map the guest pIRQ before granting access permission to the underlying host IRQ (GSI). This in particular requires that pciif.py no longer can skip this step (assuming qemu would do it) for HVM guests. This in turn exposes, however, an inconsistency between xend and qemu: The former wants to always establish 1:1 mappings

Dear Gordan, I have a Gigabyte Geforce GTX 560. Is it possible to mod it into a Quadro? If it is possible, please give me the link with the list of steps to mod it into a Quadro. Is it a simple process? Thank you very much. -- Yours sincerely, Singapore Citizen Mr. Teo En Ming (Zhang Enming)

Hi Gordan, I wanted to let you know that today I decided to have a try for my GTX 680. Gigabite GTX 680 2048 MB GDDR5. I know that this particular card could be hard-moded to GRID K2 so VGA passthrough could work. Following instructions found on http://www.eevblog.com/forum/chat/hacking-nvidia-cards-into-their-professional-counterparts/420/ I just removed two resistors. Here is a screenshot

Hi Gordan, I received my Asus GTX 480 today (bought on ebay). Finally I succeeded in - quadrifying my GTX 480  into a Quadro 6000 ( softmod). - overpassing the 3-4GB of RAM on Windows XP 64 bits (domU) by applying a well known patch for Xen. - playing Crysis 2 and Darksiders II for a few minutes. http://img11.hostingpics.net/pics/953254ScreenshotXenSoftModedQuadro6000.png Using nvlfash I

Hi All- Is it possible yet to pass through a ATI or Nvidia GPU as the primary VGA card to a Win 7/8 VM, and have it fully functional there (DXVA etc), without crashing the guest or the host during operation or when resetting the guest? For hardware I have an E3 v2 Xeon, Tyan S5512 board, and an ATI 7750. Thanks! David _______________________________________________ Xen-users mailing list

I''m using Xen 4.3, installed from source on Ubuntu 13.04. I''ve successfully installed a Windows 8 guest, and had Xen pass it an AMD FirePro W7000 GPU (technically 2 PCI devices - the second is for the sound), as well as the virtualised graphics adapter. Windows finds the card fine, and I''ve installed AMD''s drivers. Device Manager says that the card cannot

Hi everyone, CUDA allows to call some runtime functions also from the device code. On a multi-GPU system this allows the GPU to determine its device id on its own via cudaGetDevice(). Unfortunately i cannot get it working when compiling with clang. When compiling with nvcc relocatable device code needs to be set to true (-rdc=true) and the cudadevrt is needed when linking [0]. I did not

Hello, I''ve successfully passed a unmodified GTX 760 to Win7 x64. It involved some driver patching on the client side but I''m close to getting the required steps on the server side, too. Are there any legal issues that might arise from releasing a patch? Bob [image: Inline image 1] _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org

I just built 4.3.0 in order to get > 2GB of RAM in domU with GPU passthrough without crashes. Unfortunately, the same crashes still happen. Massive frame buffer corruption on domU before it locks up solid. It seems the PCI memory stomp is still happening. I am using qemu-dm, as I did on Xen 4.2.x. So whatever fix for this went into 4.3.0 didn''t fix it for me. Passing less than 2GB

I just wanted to drop a note to say that I have managed to get VGA passthrough working with multiple cards and domUs. The cards I am using are quasi Quadro 5000 (modified GTX470) and quasi Quadro 6000 (modified GTX480). (Here is an older article about modified GTS450 modified to Quadro 2000 if anyone is interested:

I''m looking to try BTRFS on a SSD, and I would like to know what SSD optimizations it applies. Is there a comprehensive list of what ssd mount option does? How are the blocks and metadata arranged? Are there options available comparable to ext2/ext3 to help reduce wear and improve performance? Specifically, on ext2 (journal means more writes, so I don''t use ext3 on SSDs,

Due to popular demand, I have finally found time to write this up. I had to rush it a little, but hopefully you get the gist. http://www.altechnative.net/2013/11/25/virtualized-gaming-nvidia-cards-part-3-how-to-modify-a-fermi-based-geforce-into-a-quadro-geforce-gts450gtx470gtx480-to-quadro-200050006000/ Any questions, please ask away, and I''ll update the article to expand on those

Greetings from a newbie! (Well, to this list anyway) I''m having a problem and I hope someone here might be able to help... I am strongly expecting an answer along the lines of "upgrade to v2.4.x", but I would REALLY preffer to avoid that for now... The setup: "Home brewed" v2.2.24 (will patch to v2.2.25 later today) with the DS8 patch applied. Currently
