2005-09-29[PATCH] Removed remaining PCI specific references from swiotlb.cTony Luck
Matthew Wilcox pointed out that swiotlb.c implements a generic interface that is not tied to just PCI. Remove includes of <linux/pci.h>, <asm/pci.h>. Fix comments and printk() messages to no longer refer to PCI. Signed-off-by: Tony Luck <tony.luck@intel.com>
2005-09-29[PATCH] swiotlb: file header commentsJohn W. Linville
Change comment at top of swiotlb.c to reflect that the code is shared with EM64T (i.e. Intel x86_64). Also add an entry for myself so that if I "broke it", everyone knows who "bought it"... :-) Signed-off-by: John W. Linville <linville@tuxdriver.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2005-09-29[PATCH] swiotlb: support syncing DMA_BIDIRECTIONAL mappingsJohn W. Linville
The current implementation of sync_single in swiotlb.c chokes on DMA_BIDIRECTIONAL mappings. This patch adds the capability to sync those mappings, and optimizes other syncs by accounting for the sync target (i.e. cpu or device) in addition to the DMA direction of the mapping.

2005-09-29[PATCH] swiotlb: support syncing sub-ranges of mappingsJohn W. Linville
This patch implements swiotlb_sync_single_range_for_{cpu,device}. This is intended to support an x86_64 implementation of dma_sync_single_range_for_{cpu,device}. Signed-off-by: John W. Linville <linville@tuxdriver.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2005-09-29[PATCH] swiotlb: cleanup some code duplication cruftJohn W. Linville
The implementations of swiotlb_sync_single_for_{cpu,device} are identical. Likewise for swiotlb_syng_sg_for_{cpu,device}. This patch move the guts of those functions to two new inline functions, and calls the appropriate one from the bodies of those functions. Signed-off-by: John W.

2005-09-29[PATCH] swiotlb: move from arch/ia64/lib/ to lib/John W. Linville
The swiotlb implementation is shared by both IA-64 and EM64T. However, the source itself lives under arch/ia64. This patch moves swiotlb.c from arch/ia64/lib to lib/ and fixes-up the appropriate Makefile and Kconfig files. No actual changes are made to swiotlb.c. Signed-off-by: John W.
