Date: Mon, 20 Dec 2010 23:08:19 +0100 From: Linus Walleij <linus.walleij@...ricsson.com> To: Per Forlin <per.forlin@...ricsson.com> Cc: Dan Williams <dan.j.williams@...el.com>, linux-kernel@...r.kernel.org, Per Forlin <per.forlin@...aro.org> Subject: Re: [PATCH] dmaengine: dma40: Add support to split up large elements 2010/12/20 Per Forlin <per.forlin@...ricsson.com>: > The maximum transfer size of the stedma40 is (64k-1) x data-width. > If the transfer size of one element exceeds this limit > the job is split up and sent as linked transfer. > > Signed-off-by: Per Forlin <per.forlin@...aro.org> Acked-by: Linus Walleij <linus.walleij@...ricsson.com> I think this could actually go into 2.6.37 series: I consider it a bug fix since the transfer size limitation breaks the contract of the memcpy() API.
