Hi While considering upgrading my MythTV backend to a VT-d capable system, I'm trying to figure out if it would be possible to utilize PCI passthrough with KVM. As far as I understand the wiki page on "How to assign devices with VT-d" [1] and various posts on mailing lists, then all conventional PCI devices should (hopefully) work, as long as they don't share an IRQ with another device, and IF they share a IRQ, the device must be MSI capable - is this assumption correct? I know that graphics cards are special, but I'm only interested in TV tuners in my specific case. I don't know if anyone has tested TV tuners on KVM, which perhaps makes it a hard question, but would you expect that a regular PCI TV Tuner with onboard MPEG2 encoder (not PCI Express, not MSI-capable, using a unique IRQ) would work? If it makes any difference, the TV tuners are all Hauppauge PVR-150/250, recognized by lspci as "Multimedia video controller: Internext Compression Inc iTVC16 (CX23416) MPEG-2 Encoder". Thanks in advance :) Best Regards Kenni Lund [1] http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
