From: Haavard Skinnemoen Date: Thu, 29 Nov 2007 00:21:43 +0000 (-0800) Subject: dmaengine: correct invalid assumptions in the Kconfig text X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=6d4f5879b6f4da50bde94e1cae73755978ed048f;p=deliverable%2Flinux.git dmaengine: correct invalid assumptions in the Kconfig text This patch corrects recently changed (and now invalid) Kconfig descriptions for the DMA engine framework: - Non-Intel(R) hardware also has DMA engines; - DMA is used for more than memcpy and RAID offloading. In fact, on most platforms memcpy and RAID aren't factors, and DMA exists so that peripherals can transfer data to/from memory while the CPU does other work.
