Actually I let it run a bit longer and both of the highest execution are network related. ndis.sys and adf.sys. Come to think of it, you're using a different ethernet port than I am. I wonder if that may have some issue. I'm using the 10G port, which I don't really have a use for right now, the rest of my network is gigabit.

I get what your saying, I think its saying that they should be in the included range. You know how you left out cores 8/24? Well I think they have to be on the same "domain" to be used at all, well to at least get the most out of them. At least that's the way I interpret it. I've tweaked my config for now just so they're all on the same domain. I'll fix it later when I change my isolcpus at reboot. Here's some updates as well, seems that storport.sys is whats giving me the highest execution time. Gonna see if I can track down any gains there.

Yea, I didn't grasp the concept that the initial post was making about creating a pci root bus and assigning it vs a card. The more recent activity there does seem like that the bulk of improvements should come with QEMU updates...whenever we get those. The guy I got it from said that the last lines in his xml we for a patched QEMU. I was also recommend "hugepages", but after a cursory search it seems that unraid enabled that by default. Couldn't get a vm to load with it enabled. <qemu:commandline> <qemu:arg value='-global'/> <qemu:arg value='pcie-root-port.speed=8'/> <qemu:arg value='-global'/> <qemu:arg value='pcie-root-port.width=16'/> </qemu:commandline>

. Ladies and gentlemen, we got'em. Massive thanks to reddit user setzer with helping on this. I don't think he's on unraid but his help was invaluable. Latency is now down to at least manageable levels. I'll continue more tweaking. His .xml = https://pastebin.com/GT1dySwt My .xml = https://pastebin.com/yGcL0GNj and he also sent along some additional reading for us. https://forum.level1techs.com/t/increasing-vfio-vga-performance/133443

Got it. My board already had a 2.x bios when I got it, and I updated to 3.5 before I really got into most of this. It's kinda confusing with old and new information being mixed in, especially on a pinned thread. Just about to try a new vm with q35 bios. BTW I noticed something with my i440 vm. Remember how you said I forgot a portion of the epic hack. Well turns out I checked my new vm, and it seems like that portion just gets deleted in a i440 .xml. Edit: With q35 the .xml changes, specifically these lines <cpu mode='custom' match='exact' check='full'> <model fallback='forbid'>EPYC-IBPB</model> stayed in the .xml. In both instances, windows still recognized it as a Epic.

Yea, that's exactly what mine was doing. I just had an idea but i'm heading out and can't test atm. I think to get uefi working i read somewhere that you need to add it in your syslinux like: kernel /bzimage append vfio-pci.ids=10de:1b06,10de:10ef isolcpus=9-15,25-31 initrd=/bzroot those ids being your gpu and gpu audio.

Thanks man, I figured it out. Well the most recent issue. Disabling CSM only lets you boot unraid USB in UEFI. Evidently it shits the bed when you do so. I managed to get into a vm with csm disabled and latency was great. Not sure if that was just due to no nvidia drivers loaded, or thats actually the fix. Can you actually boot and USE unraid if it boots as UEFI? CSM - disabled = Big Problems Launch PXE OpROM Policy - Legacy only =all network boot stuff disabled Launch Storage OpROM Policy - Legacy only Launch Video OpROM Policy - Legacy only Fast Boot - disabled = yep Secure Boot - disabled =yep SD Configuration Mode - disabled = there were two of these "sd configuration mode, and eMMC/sd configuration" (currently reenabled to get shit working again, will test in a few) EDIT: disabled both ACS enabled - auto = think it was auto (will check on this next reboot) NVMe Raid Mode - disabled = yep ACPI HPET Table - enabled = yep Deep Sleep - disabled = didn't see it but anything suspend related was off AMD fTPM switch - disabled = yep SMT Mode - auto = yep also to note the choices for "memory interleaving" are "none, channel, die, socket or auto". I selected channel.
