Subject: [PATCH 0/2] iommu: Support pages size other than 4K
Date: Tue, 1 Oct 2013 13:54:08 +1000 [thread overview]
Message-ID: <1380599650-9541-1-git-send-email-alistair@popple.id.au> (raw)
This series of patches adds support for iommu page sizes other than
4K. Currently iommu page sizes are hardcoded to 4K. This series does
not actually change the page size but adds support for doing so.
It has been tested on a pSeries machine.
