Hello Andrew, > The serial driver is also used for Atmel's AVR32 architecture. > There was some bug in the DMA patch that causes it to fail there - > Haavard was going to look into in when he had time. > Once that is resolved, the DMA patch will be submitted to mainline. In that case, shall I create a new patchset for this compared to mainline? Then we can merge the DMA patch in the interrupt handler later on. (it is really difficult to do) Kind Regards, Remy - To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
