Should I enable IOMMU?

Post by Kronstadt1921 » Sat Mar 28, 2015 6:40 pm

So, I just a assembled a new system and I'm a complete Linux newbie. Should I enable IOMMU in BIOS setup? This post seems to indicate that it causes problems with Linux. However, this post suggests that you need IOMMU enabled for Linux to recognize USB 2.0 ports on newer motherboards.
My system as of 29Jul2018:
OS: 18.3 Sylvia kernel 4.15.0-29
CPU: AMD A10-7800 3.5GHz Quad-Core
Mboard: Gigabyte GA-F2A88XM-D3H FM2+
RAM: G.Skill Ripjaws X Series 2x8GB DDR3-1866
SDA: Kingston SSDNow SV300S3 120GB
SDB: WD 1003FZEX 1TB

As far aa I understend iommu is used with virtualization, if you not doing virtialization with hardware pass through you can leave it off. However all my hardware have it on and I don't see any issues using linux
