I''m wondering if FLR really must be supported by the PCI card for PCI/VGA passthrough to work or if it will work anyway. I have read in the VTdHowTo that trying to pass through hardware without the FLR feature will result in an error. At the same time I read on a pdf document on the VMWare website (http://www.vmwa...

Hi, all, The attached patches try to improve the current FLR logic. The idea is: removing the FLR logic from hypervisor and adding the improved logic in Control Panel. The current FLR logic in hypervisor has some issues: 1) Dstate transition is not guaranteed to properly clear the device state; 2) the current code for PCIe FLR is actually buggy: PCI_EXP_DEV...

Hi As we will use xl in xen 4.1. I had try use xl to do something. And I find some command is fails. For config file, when give "disk=" too args, it will show segment fault if we use xl create to start guest. Is there any change for xl''s config file? Following command can not work: xl migrate: when I use xl migrate domain localhost to do migrate, it shows error:

I have successfully passed through a video card, network card, USB mouse, and USB keyboard to a MS Vista guest. That works well. I am trying to add another PCI device, such as a audio card or PCI USB hub, but I am running into a strange problem. When I plug the PCI audio (or USB card) to the motherboard. It makes it so that the PCI video card is no longer an "assignable device" (xm

R-sig-Debian help, Yesterday I sought help regarding R upgrading from R-2.8.1 to R-2.9.1. I must thank specially Dirk for his helpful advice. But now I am facing a dilemma. I want to install a package called FLR which works under R-2.8.1. So my question is whether I can keep the latest release (R-2.9.1) and also install R-2.8.1 (and if feasible how.) Alternatively I could uninstall R-2.9.1 and just install R-2.8.1 but as the package installation is usually on-line it might cause conflicts among packages a...

Hi everyone, I would like to ask what the current status of FLR, or better of FLR emulation is in latest Xen and if we can expect better support in the future. I''m asking because with xl (latest build and traditional qemu, not upstream), I always had problems with rebooting domUs which have vga cards passed through to them, because appearently they do...

Thanks Anna, this was also quite interesting for me. Did you mean that I just have to eliminate the else branch or raise arround "All devices behind the uppermost PCI/PCI-X bridge must be co-assigned to the same guest." or do I have to eliminate more in order to prevent an FLR (whatever that is). For my board it''s definitely necessary to move PCI devices in different guests, as all PCI slots are assigned to one bridge. It works on 3.2-1. As I don''t know what FLR is, I cannot estimate, whether others are happy about these changes, I am definitely not....

Hello all, Please try this "patch". It changes the way the noise floor is used for quantization in a not-so-subtle way. At the very end of _vp_compute_mask, add the lines: for(i=0;i<n;i++) flr[i]=.01f*sqrt(flr[i]); The .01 is there to ensure the current codebooks will work. We will really need different, newly-trained codebooks with this change; then the .01 can probably go away, though it won't hurt (I think). Be warned that the bitstreams increase roughly 50% in size with this ch...

...by the way) and really interested in xen-vga-passthru. Lately, I bought a brand new Saphire HD 7950 (OC Boost) because I saw in a wiki somewhere that users have been able to passthru these VGA devices to domU (win7, win-xp and so on). But, after I installed it, I executed *lspci -vv* to check if FLR in DevCap was present (which it''s *not*). I''ve managed, though, to put my virtual machine to work out with the HD 7950 as a secondary device. Sometimes, I have to reboot dom0 to make things work. So, here''s my question: is there any patch to help me out and solve this p...

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, I'm trying to develop an histogram method for a class called "FLQuant" which is used by the package FLCore (http://flr-project.org). FLQuant is an extension to "array". There is an as.data.frame method that coerces flquant into a data.frame suitable for lattice plotting. The problem is that when I coerce the object and plot it after it works but if the method is applied within the histogram method it does...

Aloha! Concisely, I''ve been trying for several days to get VGA/PCI passthrough working. Regarding VGA vs PCI passthrough, I''m not entirely certain of the difference? Does Xen perform a different set of operations when passing through a VGA card versus any PCIe card? I''ve read the wiki and it seems the answer is "yes;" however, when passing through a

Hi all!. First of all sorry about my English it''s not very fluid. I have a small server based upon Supermicro X7DBN (Chipset Intel® 5000P) motherboard and Intel Xeon E5320 (1,83Ghz) with 4Gb of FB-DIMM RAM. The OS is Debian Lenny in dom0 (2.6.26-2-xen-amd64) and Debian Lenny in domU (2.6.26-2-xen-amd64). Xen is 3.4.2 compiled from sources. The problem comes when I need to passthrough
