https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=222996 --- Comment #20 from Dexuan Cui <decui@microsoft.com> --- (In reply to Wei Hu from comment #19) > For the broken of PCI passthrough, I have not checked in fix yet. > I think we can just reserve the MMIO address (0xf8000000, 0xf8800000) FWIW, we can not hardcode the MMIO range that should be reserved, because the range's base address can change if the user sets the Low MMIO space size by something like "Set-VM -LowMemoryMappedIoSpace 3Gb -VMName $vm" (See https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/plan/plan-for-deploying-devices-using-discrete-device-assignment). -- You are receiving this mail because: You are the assignee for the bug.help
