https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207447 Bug ID: 207447 Summary: Add hw.pci.honor_msi_blacklist=3D0 to GCE images Product: Base System Version: 10.3-BETA2 Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: misc Assignee: freebsd-bugs@FreeBSD.org Reporter: wac@google.com CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org Due to the way Google Compute Engine currently populates the virtual PCI bu= s it presents to VMs, sys/dev/pci/pci.c's pci_msi_blacklisted() blocks use of MS= I. Since there is no 0:0:0 bridge device the existing workarounds there, such = as the one for qemu, won't work. Adding hw.pci.honor_msi_blacklist=3D0 to /boot/loader.conf on the images in= tended for Google Compute Engine will allow use of MSI, which is supported by the platform. Efforts are underway to make this unnecessary, but are unlikely to be compl= ete before 10.3-RELEASE. --=20 You are receiving this mail because: You are on the CC list for the bug.=
