Linville" Date: Mon, 26 Sep 2005 21:01:19 +0000 Subject: [patch 2.6.14-rc2 0/5] swiotlb maintenance and x86_64 dma_sync_single_range_for_{cpu,device} Message-Id: <09262005170119.15628@bilbo.tuxdriver.com> List-Id: In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-kernel@vger.kernel.org, discuss@x86-64.org, linux-ia64@vger.kernel.org, linux-pci@atrey.karlin.mff.cuni.cz Cc: ak@suse.de, tony.luck@intel.com, Asit.K.Mallick@intel.com, gregkh@suse.de Conduct some maintenance of the swiotlb code: -- Move the code from arch/ia64/lib to drivers/pci -- Cleanup some cruft (code duplication) -- Add support for syncing sub-ranges of mappings -- Add support for syncing DMA_BIDIRECTIONAL mappings -- Comment fixup & change record Also, tack-on an x86_64 implementation of dma_sync_single_range_for_cpu and dma_sync_single_range_for _device. This makes use of the new swiotlb sync sub-range support. In this round, the new location for swiotlb is driver/pci/swiotlb.c. This is the result of discussions on lkml pointing-out that swiotlb is closely related to PCI. Patches to follow...
