From 165785e5c0be3ad43e8b8eadfbd25e92c2cd002a Mon Sep 17 00:00:00 2001 From: Jeremy Kerr Date: Sat, 11 Nov 2006 17:25:18 +1100 Subject: [POWERPC] Cell iommu support This patch adds full cell iommu support (and iommu disabled mode). It implements mapping/unmapping of iommu pages on demand using the standard powerpc iommu framework. It also supports running with iommu disabled for machines with less than 2GB of memory. (The default is off in that case, though it can be forced on with the kernel command line option iommu=force).
