I had the arc b50 working a few days ago split between 2 virtual machines, I was testing the rebardxe bios mod before I ordered some more parts for the server.
fast forward to last night I had rebooted the server and I lost my vfgpus(i didnt save the set up via sysfutils).. and now i cant seem to get the gpu to sriov im getting dmseg error “not enough memory” (-ENOMEM)
im not at home so I cant spin the server back up, ive tried the usual pci=realloc in grub but that doesnt seem to fix it either.
anyone have ideas on where to start?
I do have another 7502 for the 2nd socket that should be here by friday, there is a 2nd riser that uses cpu1 instead of cpu0 hoping that might solve my problem
I think I figured it out, after an update the bar size goes to 16GB when the XE driver is loaded. looking at the other posts theres a way to manually set the VF size and the bar size of the physical card. I can unbind the the card from the xe driver and set it to 2gb but when the driver is loaded it goes back to 16gb. I am sort of new to this but this is as far as I’ve gotten with trying to get sr-iov to work
