This patchset convert the PPC64 IOMMU to use the iova code for free area management. The IOMMUs ignores low level drivers' restrictions, the maximum segment size and segment boundary. I fixed the former: http://thread.gmane.org/gmane.linux.scsi/35602 The latter makes the free area management complicated. I'd like to convert IOMMUs to use the iova code (that intel-iommu introduced) for free area management and enable iova to handle segment boundary restrictions, rather than fixing all the IOMMUs' free area management, I converted the PPC64 IOMMU to see how things work. The patchset was slightly tested with a pSeries box and seems to work. This is against the latest Linus' git tree with David Miller's genericizing iova patch: http://www.ussg.iu.edu/hypermail/linux/kernel/0710.2/2910.html This patchset is also available: git://git.kernel.org/pub/scm/linux/kernel/git/tomo/linux-2.6-misc.git iova - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
