2010-12-04drivers/dma/ioat: Use the ccflag-y instead of EXTRA_CFLAGSTracey Dent
Changed Makefile to use <modules>-y instead of <modules>-objs. Following (documentation/kbuild/makefiles.txt). Signed-off-by: Tracey Dent <tdent48227@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2009-09-08ioat3: split ioat3 support to its own file, add memsetDan Williams
Up until this point the driver for Intel(R) QuickData Technology engines, specification versions 2 and 3, were mostly identical save for a few quirks. Version 3.2 hardware adds many new capabilities (like raid offload support) requiring some infrastructure that is not relevant for v2. For better code organization of the new funcionality move v3 and v3.2 support to its own file dma_v3.c, and export some routines from the base files (dma.c and dma_v2.c) that can be reused directly. The first new capability included in this code reorganization is support for v3.2 memset operations. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2009-09-08ioat2,3: convert to a true ring bufferDan Williams
Replace the current linked list munged into a ring with a native ring buffer implementation. The benefit of this approach is reduced overhead as many parameters can be derived from ring position with simple pointer comparisons and descriptor allocation/freeing becomes just a manipulation of head/tail pointers. It requires a contiguous allocation for the software descriptor information. Since this arrangement is significantly different from the ioat1 chain, move ioat2,3 support into its own file and header. Common routines are exported from driver/dma/ioat/dma.[ch]. Signed-off-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2009-07-28ioat: move to drivers/dma/ioat/Dan Williams
When first created the ioat driver was the only inhabitant of drivers/dma/. Now, it is the only multi-file (more than a .c and a .h) driver in the directory. Moving it to an ioat/ subdirectory allows the naming convention to be cleaned up, and allows for future splitting of the source files by hardware version (v1, v2, and v3).
