From mboxrd@z Thu Jan 1 00:00:00 1970 From: cyrille.pitchen@atmel.com (Cyrille Pitchen) Date: Thu, 18 Jun 2015 13:25:40 +0200 Subject: [PATCH linux-next v2 0/1] dmaengine: at_hdmac: fix residue computation Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org ChangeLog v2: - rework the processing of the linked list of DMA descriptors to take a race condition risk into account. See patch comments for more details on why we have chosen this implementation. v1: This patch fixes a bug reported by Jiri Prchal for the USART behaviour on some Atmel SoCs when DMA is used to receive data. More generally, it fixes the DMA residue computation.
