PCI device doesn't show in XO or xe pci-list

Pyroteq

I have a TV tuner card I use with my Plex Media Server.

I've successfully used the command line to pass this device through to the VM and it works fine, but recently I upgraded to XCP-NG 8.3 and saw that there is now new options in XO to make pass through much easier so I figured I'd give it a try.

Unfortunately it appears that not all PCI devices are listed including my TV Tuner card.

Is there a reason some devices are detected and others aren't?

Hi,

Just to be sure I understand, you can see the device with lspci (as the CX23887/8 Broadcast thing) but it's not listen in XO web UI, right?

chicagomed

This seems very similar to the problem I am having with my arc Arc310 Not Showing Up in Passthrough.

Perhaps there is a broader issue for these 'less than standard' PCI passthroughs?

Pyroteq

@olivierlambert

Correct. The webUI seems to reflect whatever is in xe pci-list, but what appears in this list seems somewhat random when compared to the full lspci list.

Perhaps xe pci-list could be made to be a bit more broad in what it can detect?

olivierlambert

Same answer than the other topic, checking first the basics before investigating further

chicagomed

@olivierlambert I'm going to swap in an AMD card today and will let you know if anything changes!

Pyroteq

@olivierlambert

My issue isn't that I can't pass through the card at all, I can still do it via CLI just fine so there isn't really any real problem preventing me from hiding the card from dom0 and then attaching it to my Plex VM. I was just curious why some devices are listed with xe pci-list and others aren't because I would have thought that it would essentially just reflect whatever shows in lspci.

Having it show in xe pci-list would just mean it's easier to attach/detach from a VM as it would then show in the webUI.

Does XCP-NG require the built in driver support to list the devices in pci-list?? Because the TV tuner doesn't work natively on Linux without downloading the drivers so I guess that could be a possibility?

olivierlambert

@Pyroteq OK so it's more clear to me now. So there's an issue on how we report all the devices to make it doable via Xen Orchestra. I'm not sure exactly who to ping, maybe @Team-Hypervisor-Kernel

marcoi

im seeing a similar thing in lastest version of XO (self built)
lspci showing more items the XO is showing for the host.
I just added a usbc card for example and its not showing up in XO.

marcoi

Just to add details about my box. Seems lspci is showing 20 items and xe/xo is only showing 12.
I left the device name in the second list to help show whats not showing up in xe vs lscpi

Just adding here from my other post---AMD card didn't not reproduce this issue but my Intel Arc card experience matches exactly what others have posted here about the LSPCI vs XE-Assignable / XOA list difference.
