https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D222996 --- 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 t= he 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). --=20 You are receiving this mail because: You are the assignee for the bug.=
