| |
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)? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
