Aside from that I applied Diff 79310. I also needed to add #include #include to pci_emul.c to find the VM_MAXUSER_ADDRESS macro constant. I lower the limit from 128 MB to 32 MB (because I want to test if your patch fixes the 64 bit mapping, and my BAR is 128 MB.) Then I get: wrmsr to register 0xc0011029(0x3) on vcpu 0 rdmsr to register 0xc00000e9 on vcpu 0 Unhandled ps2 mouse command 0xe1 Unhandled ps2 mouse command 0x88 Assertion failed: (pi->pi_bar[baridx].type =3D=3D PCIBAR_IO), function passthru_write, file /usr/src/usr.sbin/bhyve/pci_passthru.c, line 916. --=20 You are receiving this mail because: You are the assignee for the bug.=
