Currently llvm 8 is in the tree. We stopped updating when the license changed for the worse. With llvm versions being tied to amd hardware support and newer c++ standards, not updating is becoming increasingly painful as time goes by so this may have to change in the near future. I would expect the modesetting driver to be able to run even if amdgpu with acceleration does not. I'm not sure why it does not fallback. > > > /etc/sysctl.conf > > > machdep.allowaperture=1 > > > dmesg > > > OpenBSD 6.7-current (GENERIC.MP) #358: Sat Jul 18 11:25:13 MDT 2020 > > dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP > > real mem = 17111711744 (16319MB) > > avail mem = 16578068480 (15810MB) > > random: good seed from bootblocks > > mpath0 at root > > scsibus0 at mpath0: 256 targets > > mainbus0 at root > > bios0 at mainbus0: SMBIOS rev. 2.8 @ 0xdcecf000 (59 entries) > > bios0: vendor American Megatrends Inc. version "1.C0" date 09/06/2019 > > bios0: Micro-Star International Co., Ltd.

amdgpu: AMD 5700XT (NAVI10) misreported and non-working
I saw that much of the amdgpu related drm code had been updated against linux 5.7 and decided to try it out using a recent snapshot. While the amdgpu module loads and is able to mirror to both of my displays when in a tty, attempting to use startx or starting xenodm results in both displays showing a blank black screen. When this occurs I am unable to switch to another tty though I am able to SSH into the system and poke around. /etc/sysctl.conf > machdep.allowaperture=1 dmesg > OpenBSD 6.7-current (GENERIC.MP) #358: Sat Jul 18 11:25:13 MDT 2020 > dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP > real mem = 17111711744 (16319MB) > avail mem = 16578068480 (15810MB) > random: good seed from bootblocks > mpath0 at root > scsibus0 at mpath0: 256 targets > mainbus0 at root > bios0 at mainbus0: SMBIOS rev. 2.8 @ 0xdcecf000 (59 entries) > bios0: vendor American Megatrends Inc. version "1.C0" date 09/06/2019 > bios0: Micro-Star International Co., Ltd.

OK good to know, thanks. I was unaware that the boot parameters
could be specified there rather than by editing TXT.CFG in the
boot image.

No.

Perhaps not. I tried a variety of things with bridge0, like
attempting to add my host's egress interface (iwm0) to it,
resulting in a "Device busy" error. I also tried creating a vether
device and attaching that, as described in the Virtualization FAQ.
Using tcpdump on tap0, I was able to see bootp and arp packets
coming from the guest. I did not see any replies from the host
though. Running tcpdump on bridge0 did not show any packets no
matter what I tried.

I tried -L but vmctl didn't seem to like that in combination with
a VM specified in vm.conf. I also tried replacing 'interface {
switch "uplink" }' with 'local interface' but that didn't seem to
make a difference.
Thanks for the help so far!

PCI passthru now working for OpenBSD guests in FreeBSD bhyve
Hi All, Just FYI, after years of PCI passthru* not working for OpenBSD guests in FreeBSD bhyve due to 2 bugs, a week ago the fixes were made available in FreeBSD 12.1-RELEASE-p7. Now it's possible to use a OpenBSD guest as a main firewall for a FreeBSD host, OpenBSD guest taking full control of the internet-connected NIC, isolating this way the host and other guests from unrestricted network flow. The details were recently published in the FreeBSD Quarterly Status Report - Second Quarter 2020: [1]. Regards, Anatoli * PCI devices passthru is a technique to pass host PCI devices to a virtual machine for its exclusive control and use.

With the virtio modules now included in the installer you can skip my
tutorial. You only need to change bootparameters in GRUB to pass
vga=off console=ttyS0,115200n8 to the linux kernel.
As for DHCP, it depends on your config: is pf blocking DHCP traffic?
is the bridge/switch interface set up correctly?
is sysctl net.inet.ip.{m,}forwarding set to 1?
do you use vmctl -L (local interface)?
Re: I hold the ctrl key and boot still runs my boot.conf
I guess this would explain it.
/usr/src/sys/arch/amd64/stand/efiboot/efiboot.c:
efi_cons_getshifts(dev_t dev)
{
/* XXX */
return (0);
}
Any reason for this?

I skipped the part about the virtio-modules which doesn't seem to be necessary now (and the link is 404 now anyway). I was able to go through the menu (starting with Install, and skipping the modprobe commands) but DHCP didn't work, and I'm not sure what's broken. To answer your question, you need to press Esc _after_ selecting Install. Maybe that's why you saw the "boot>" prompt. It worked for me and I just ran lsmod since I didn't have any modules to insert: ~ # lsmod Module Size Used by virtio_blk 20480 0 virtio_net 32768 0 virtio_pci 24576 0 virtio_ring24576 3 virtio_blk,virtio_net,virtio_pci virtio 16384 3 virtio_blk,virtio_net,virtio_pci I hope this helps, and please let me know if you or anyone else has an idea of why DHCP isn't working in the guest VM.
