Subject: pci-dma disables iommu on nforce4 motherboards?
Date: Sat, 24 Dec 2005 10:20:47 -0500 [thread overview]
Message-ID: <43AD674F.1040008@comcast.net> (raw)
I have an asus A8N-E motherboard and recieve the following message on
boot.
PCI-DMA: Disabling IOMMU.
I have no issues with anything not functioning. I guess i'm just
curious as to why this is done and if i'm missing out on any sort of
performance gain by not using the iommu. I have less than 4GB of ram,
would that be why it's disabled (which is why i think it is)?
