2011-11-30CHROMIUM: ASoC: Tegra: Double-buffer DMA in HWStephen Warren
Avoid audio FIFO underflow due to DMA ISR latency. MODE_ONESHOT works like this: * CPU tells DMA HW to make a transfer . * DMA HW performs the transfer, fires an interrupt, and goes idle. * Interrupt latency (including e.g. LP2 exit time) is seen here. * DMA driver ISR programs the next transfer, from a SW transfer queue. In that model, the interrupt latency must be hidden by the I2S FIFO, which is 16 samples IIRC, i.e. a very short time (~0.3mS @ 48KHz). MODE_CONTINUOUS_SINGLE works like this: * CPU tells DMA HW to make a transfer . * CPU tells DMA HW to make a second transfer. * DMA HW performs the transfer, fires an interrupt, and starts the second transfer immediately. * DMA driver ISR programs the next (third) transfer, while the second is in progress, from a SW transfer queue. Thus any DMA ISR latency is seen between transfer N completing and transfer N+2 starting (rather than N+1), since the HW itself already knows how to perform transfer N+1 before transfer N completes. Hence, the system is tolerant of much larger latencies.
