    PCI Passthrough Success!

    Yesterday I found out my current cpu / mobo could support iommu. As such I achieved a goal I've wanted awhile now. How to run my Windows games easily while still being able to run Linux without dual booting. Always knew about passthrough but assumed I didn't have the hardware capable.

    i5 3470, 16gb of ram, rx570 gpu, 120gb ssd with Xubuntu on it, 250gb ssd holding my kvm image.

    It took a bit of fiddling about but I got it worked out and it runs beautifully. I'm waiting for a 1080p hdmi dummy plug so I can get my 1600x900 monitor and plug it back into my mobo graphics with my 1080p main. Thus far though I've been testing my Steam streaming from it > the same desktop and the performance doesn't seem to be any different than streaming to my tv on a whole other machine. solid fps, not crazy but definitely workable. Running world of warcraft just roaming around the the cities / out killing stuff the cpu never gets above 50% so it seems to have some headroom. I have not tried running about the newest expansion. 50fps on average doing that. It's beautiful. I'm very pleased.

    Right now I'm envisioning a future system with 8 4tb spinning drives in zfs raidz2 with 64gb of ram, high core count cpu Ryzen or something along with an RX6800 for each windows instance. It would be a full windows gaming machine backed by zfs. The possibilities are endless. Suck it UNRAID.

    Are you like me mystified as to the topic of this thread?

    Wikipedia didn't enlighten me much. But congratulations @Tadaen_Sylvermane

    It is a machine. It is more stupid than we are. It will not stop us from doing stupid things.

    Yes i am mystified still. I didn't figure it out myself and am clueless on how it all works. I googled. But it works and it's a simple process assuming you have the hardware.
