vorlon, we couldn't add an ethernet adapter via PCI passthrough with the slof.bin included in the distro. We can see the following message right after boot: Populating /pci@800000020000000 Warning: 64-bit PCI space not supported yet! 100000000 10120000000 Adapters on 0800000020000000 00 0800 (D) : 106b 003f serial bus [ usb-ohci ] 00 1000 (D) : 1af4 1002 unknown-legacy-device* 00 1800 (D) : 14e4 168e network [ ethernet ] 00 1900 (D) : 14e4 168e network [ ethernet ] It complains about not supporting 64-bit PCI space. When guest is done booting, we can't use the adapter because the guest's kernel (Ubuntu's 4.4.0-1-generic) can't access its PCI configuration space. The first lines of this "old" slof are: SLOF ********************************************************************** QEMU Starting Build Date = Oct 16 2014 08:49:16 FW Version = buildd@ release 20140630 Now, by updating to upstream slof (found in qemu git repo, but it seems Debian version is the same) we got the following lines on boot. Populating /pci@800000020000000 00 1900 (D) : 14e4 168e network [ ethernet ] 00 1800 (D) : 14e4 168e network [ ethernet ] 00 1000 (D) : 1af4 1002 unknown-legacy-device* 00 0800 (D) : 106b 003f serial bus [ usb-ohci ] Notice there's no more warning regarding the PCI 64-bit space, and adapter works on guest's kernel. The first lines of boot, reflecting the newer firmware, are: SLOF ********************************************************************** QEMU Starting Build Date = Nov 5 2015 15:23:31 FW Version = git-b4c93802a5b2c72f Thanks, Guilherme -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1539646 Title: [Ubuntu 16.04] Please update slof package to the upstream To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/slof/+bug/1539646/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
