[PATCH 0/3] Allocate DMA descriptors with contig DMA memory

Dave Jiang <dave.jiang@xxxxxxxxx> · Wed, 10 Feb 2016 15:00:15 -0700

The following series removes DMA descriptor ring reshape and move the
allocation of DMA descriptors to under contiguous memory. This is in
preparation of future ioatdma implementation that will allow the
hardware to prefetch descriptors in order to improve performance.
