The following series will add an API to arch code to assign a channel to a given queue. The default queue is changed from 0 (highest priority) to lowest priority. In the dmaengine driver we move the cyclic channel to queue0 (highest priority) and move it back to default queue when the channel is terminated. Regards, Peter --- Peter Ujfalusi (3): ARM: edma: Set default queue to lowest priority ARM: edma: Add edma_assign_channel_eventq() to move channel to a give queue dma: edma: Serve cyclic (audio) channels with high priority queue arch/arm/common/edma.c | 31 ++++++++++++++++++++++++++++++- drivers/dma/edma.c | 8 ++++++++ include/linux/platform_data/edma.h | 2 ++ 3 files changed, 40 insertions(+), 1 deletion(-) -- 2.0.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
