Olof Johansson 2889773131 [PATCH] powerpc: Lower threshold for DART enablement to 1GB ... Turn on the DART already at 1GB. This is needed because of crippled devices in some systems, i.e. Airport Extreme cards, only supporting 30-bit DMA addresses. Otherwise, users with between 1 and 2GB of memory will need to manually enable it with iommu=force, and that's no good. Some simple performance tests show that there's a slight impact of enabling DART, but it's in the 1-3% range (kernel build with disk I/O as well as over NFS). iommu=off can still be used for those who don't want to deal with the overhead (and don't need it for any devices).
