Still looking 😵💫

Best one yet, managed to get USB dev as a ppt dev.
#SmartOS and i did not agree with ppt_aliases or ppt_matches.
#OmniOs and pcieadm utility made it understandable on my level
prtconf -dD is ALOT 😂
But after i have seen output of pcieadm it makes more sense.
So tomorrow i will try my favorite #tribblix to see if we can get passthrough going
Intel Arc PCI Passthru using bhyve on illumos
A while ago I bought a second hand NVIDIA Quadro P1000 on eBay, it being a Low-Profile card, means it fits well in my 2U servers in my home lab. This card has been used in my Plex Media Server VM for a while, although it is working well, it is a few generations old and does not support newer codecs like h265 and AV1. Intel recently launched the Intel Arc A3101 which does support all the newer codecs, additionally one can avoid the horrible mess that is NVIDIA drivers on Linux! The i915 driver in kernel supports Arc, assuming one is running a recent enough version.
I think i got it!
because i got my USB card passtrough on #tribblix
This was on tribblix
prtconf -dD look for the attached device
pci1912,15 (pciex1912,15) [Renesas Electronics Corp. uPD720202 USB 3.0 Host Controller], instance #1 (driver name: xhci)
pciex1912,15 goes into /etc/ppt_matches
So you just have pciex1912,15 in that file
and ppt_aliases should read
ppt "pci1912,15"
reboot
and se.
still can't figure out how to get device path :(
Blog in previus post, the author is my hero now :D
No joy yet, the documentation is not understandable for me, how to setup a ppt device in a zone
set device
match=/dev/ppt2
and then on?

#tribblix did not like that at all 😂
Jorge Schrauwen@joany I am passing through the same device on my OmniOS hosts ...

In my case it's a card with 4 controller going to 1 port each.
Assuming for now the xhci driver is still attaching... you can iterate over them and find the correct path using:
/usr/lib/pci/pcieadm show-devs -o device,driver,bdf,path | egrep "xhci|ppt"
sjorge@jupiter:~$ /usr/lib/pci/pcieadm show-devs -o device,driver,bdf,path | egrep "xhci|ppt"

That should give you the paths for ppt_aliases
@sjorge
It was your blog i found.

Outstanding!
But what do i put in zonecfg?
This i dont get 😵💫

@joany on OmniOS when not using zadm you need the following
add device
set match="/dev/ppt5"
end
add attr
set name="ppt5"
set type="string"
set value="on"
end
You can find the right ppt device either pptadm or with the command from the previous reply.
Hmm, i have tried on a few machines here now at home.
All UEFI,
Not all where capable to pass-though a device
in some cases i got a init_node: unbind rebind error
But i have a Lenovo with a 8th gen intel that i managed to pass-though the onboard USB
But my ryzen 1600 was a no 😞
This was with #omnios
Thanks again
@joany ppt is only support on Intel CPU's currently when using bhyve on illumos. There is no IOMMU (?) driver for AMD that hooks into bhyve.
