I have this weird issue. I have a PC Engines box with a AMD SoC in it.
I'm trying to pass through the USB 3.0 controller to a Windows VM. I added:
hw.vmm.amdvi.enable="1"
pptdevs="0/16/0"
to /boot/loader.conf, rebooted, installed Windows, etc. Everything
works great until I add:
-s 5,passthru,0/16/0
to my bhyve command line. As soon as I add that (and don't change
anything else), TitanoCore suddenly can't boot from the virtual HD
anymore:
Boot Failed. EFI Hard Drive
.PXE-E18: Server response timeout.
Boot Failed. EFI Network
UEFI Interactive Shell v2.1
EDK II
UEFI v2.40 (BHYVE, 0x00010000)
Mapping table
BLK0: Alias(s):
PciRoot(0x0)/Pci(0x3,0x0)/Sata(0x0,0x0,0x0)
Press ESC in 1 seconds to skip startup.nsh or any other key to continue.
Shell>
I take the passthru back out and Windows works fine.
Does this make sense?
My full command line is:
bhyve -A -H -P -w -S -u -c sockets=1,cores=3,threads=1 -m 3G \
-s 0,amd_hostbridge \
-s 3,nvme,/dev/ada0 \
-s 5,passthru,0/16/0 \
-s 10,virtio-net,tap0,mac=4a:ab:0f:25:4c:b7 \
-s 20,virtio-rnd \
-s 31,lpc \
-l com1,/dev/nmdm0A -l
bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd win2019
Changing nvme to ahci-hd doesn't help. Only difference between the
two is that "Boot Failed. EFI Hard Drive" turns into "Boot Failed. EFI
Misc Device".
This is really strange!
Thanks,
