Xen VGA Passthrough - GTX 680 successfully hard-moded to GRID K2
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 taken from a VM (Ubuntu 12.04 32 bits) with more 8GB of RAM. http://www.eevblog.com/forum/chat/hacking-nvidia-cards-into-their-professional-counterparts/420/ I did the test on another VM (Windows 7 64 bits). I was able to play games, shutdown the VM, restart the VM without restarting the dom0. I am very impressed. Restarting domU (Linux or Windows) without restarting the dom0 is very impressive. I just added a youtube video about my tests for my hard-moded card http://youtu.be/L1RoOx8wC7A Apologies I am French so I am speaking in French in the video. Just to show that it works perfectly. Kind regards. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

As I have mentioned a number of times before, a faux-Quadro setup is far, far superior to an ATI setup when it comes to VGA passthrough. And I wouldn''t say it''s impressive per se - it is normal and expected. OTOH, having to reboot dom0 when rebooting domU is utterly broken and unfit for purpose. Gordan

So it seems to not work is booting XP64 AFTER using Win7. What I was asking was a little different, though, and specific to using dual-link DVI vs. single-link. You do, however, seem to be able to use display-port, which answers a part of my question, since that doesn''t work for me at all. Let me recap the problem. I only get this on the GTX680 (Quadrified to K5000 or Gridified to K2, happens in both cases) in domU. It does NOT happen with a GTX470/480 modified to Q5000/Q6000. On bare metal the modified GTX680 works fine, the issue does not arise. I only tried this on XP64, not attempted on Win7. Setup: - Xen 4.3.0 - XP64 domU - GTX680 modified to K5000 Symptoms: 1) Using a VGA monitor works fine. 2) Using a single-link DVI monitor works fine. 3) Using a monitor capable of dual-link DVI modes but in low resolution where the card negotiates only a SL-DVI mode (<= 1280x800 on my Dell 3007WFP) works fine. 4) Using a DL-DVI monitor with high resolution modes requiring DL-DVI link results in a blank screen (monitor goes to sleep immediately) 5) DisplayPort use with active DL-DVI adapter results in monitor going to sleep in ANY mode (low or high res). In all cases the monitor is identified correctly and it''s specific modes are listed. So to re-iterate the question - do you have a DL-DVI monitor you can try connecting to your GTX680 and see if DL modes work from domU XP64? Note: 1920x1200@60Hz is achievable using SL-DVI with reduced blanking so not all monitors that do 1920x1200 are necessarily DL-DVI. You can check this by looking at the Xorg log file if you are using the monitor on Linux, it should tell you what bandwidth is used for the mode. If if it is over 165MHz, it MUST be DL, if it is below, it may well be SL.> For GTX480/Quadro 6000 > ===================> > The latest VMs I set up were a VM Win 7 64 and a VM Win XP 64.

Is your passthrough GPU the primary in dom0? Also note that if you have modified the GTX680 to a Grid K2 (well, half of a Grid K2), you can actually soft-mod it using a similar method to the Fermi (4xx series) cards to K5000 (not that there is much point, mind you). You just have to modify both the UEFI straps in the UEFI header and the BIOS straps in the normal BIOS wrapped into all that UEFI garbage (UEFI header is 1024 bytes, or 0x400 bytes in hex). Or you could just strip out the first 0x400 bytes from the BIOS and all the trailing UEFI garbage after a little under 64KB - you can tell where the trailing padding starts by the fact it''s all 0xFF filled). At the very bottom are the UEFI crypto certs which can also be removed. But if you have gfx_passthrough=1 working without side-loading the BIOS with the 64KB limitation, there is probably no point in doing this. Gordan

So it seems to not work is booting XP64 AFTER using Win7. What I was asking was a little different, though, and specific to using dual-link DVI vs. single-link. You do, however, seem to be able to use display-port, which answers a part of my question, since that doesn''t work for me at all. Let me recap the problem. I only get this on the GTX680 (Quadrified to K5000 or Gridified to K2, happens in both cases) in domU. It does NOT happen with a GTX470/480 modified to Q5000/Q6000. On bare metal the modified GTX680 works fine, the issue does not arise. I only tried this on XP64, not attempted on Win7. Setup: - Xen 4.3.0 - XP64 domU - GTX680 modified to K5000 Symptoms: 1) Using a VGA monitor works fine. 2) Using a single-link DVI monitor works fine. 3) Using a monitor capable of dual-link DVI modes but in low resolution where the card negotiates only a SL-DVI mode (<= 1280x800 on my Dell 3007WFP) works fine. 4) Using a DL-DVI monitor with high resolution modes requiring DL-DVI link results in a blank screen (monitor goes to sleep immediately) 5) DisplayPort use with active DL-DVI adapter results in monitor going to sleep in ANY mode (low or high res). In all cases the monitor is identified correctly and it''s specific modes are listed. So to re-iterate the question - do you have a DL-DVI monitor you can try connecting to your GTX680 and see if DL modes work from domU XP64? Note: 1920x1200@60Hz is achievable using SL-DVI with reduced blanking so not all monitors that do 1920x1200 are necessarily DL-DVI. You can check this by looking at the Xorg log file if you are using the monitor on Linux, it should tell you what bandwidth is used for the mode. If if it is over 165MHz, it MUST be DL, if it is below, it may well be SL.> For GTX480/Quadro 6000 > ===================> > The latest VMs I set up were a VM Win 7 64 and a VM Win XP 64.

You just have to modify both the UEFI straps in the UEFI header and the BIOS straps in the normal BIOS wrapped into all that UEFI garbage (UEFI header is 1024 bytes, or 0x400 bytes in hex).

If it was working, the BIOS level and bootup output should come up on the passthru GPU, should it not? I guess gfx_passthru=1 just disables the emulated Cirrus VGA, but in that case the boot-up animation shouldn''t show up on VNC. So I''m not sure what is going on in this case. Gordan

Re: [Xen-devel] Xen VGA Passthrough - GTX 680 successfully hard-moded to GRID K2
There is one exception for the boot-up animation if you have a domU where ATI card was installed. I have a domU Win 7 64 which I use for my previous ATI tests. After removing my ATI card and putting my GTX 680 back in this domU I remove AMD driver and I installed NVIDIA driver. When this domU is starting up the boot-up animation appears only in the VNC console. After that the animation is "frozen" on boot-up animation in VNC and the Windows screen (login screen) appears in my physical monitor. This domU above is a different domU than the 2 other domUs (Win XP 64 and Win 7 64) freshly installed. ________________________________ De : Gordan Bobic <gordan@bobich.net> À : David TECHER <davidtecher@yahoo.fr> Cc : xen-users@lists.xen.org; Pasi Kärkkäinen <pasik@iki.fi>; xen-devel@lists.xen.org Envoyé le : Mercredi 25 septembre 2013 18h07 Objet : Re: [Xen-users] [Xen-devel] Xen VGA Passthrough - GTX 680 successfully hard-moded to GRID K2 On Wed, 25 Sep 2013 17:02:59 +0100 (BST), David TECHER <davidtecher@yahoo.fr> wrote:>>I _may_ be wrong here, but doesn''t the gfx_passthru=1 get ignored > >in that case?

Re: [Xen-users] Xen VGA Passthrough - GTX 680 successfully hard-moded to GRID K2
I haven''t tried plugging it into a TV to get audio output tested, but the HDMI audio device gets detected in domU and shows up as functioning without any issues. So unless somebody has evidence to the contrary, it almost certainly works just fine.

Re: [Xen-devel] Xen VGA Passthrough - GTX 680 successfully hard-moded to GRID K2
Thanks for the feedback! Do you have the dom0 reboot problem with the 7750? (That is the same card I have as well). -D On Sat, Sep 28, 2013 at 4:20 PM, David Sutton <kantras@gmail.com> wrote:> David, > > (Removing xen-devel from CC list) > > On Sat, Sep 28, 2013 at 2:18 PM, Gordan Bobic <gordan@bobich.net> wrote: > >> I haven''t tried plugging it into a TV to get audio output tested, but the >> HDMI audio device gets detected in domU and shows up as functioning without >> any issues.
