2016-07-12dmaengine: imx-sdma: ack channel 0 IRQ in the interrupt handlerMichael Olbrich1-15/+8
Currently the handler ignores the channel 0 interrupt and thus doesn't ack it properly. This is done in order to allow sdma_run_channel0() to poll on the irq status bit, as this function may be called in atomic context, but needs to know when the channel has finished. This works mostly, as the polling happens under a spinlock, disabling IRQs on the local CPU, leaving only a very slight race window for a spurious IRQ to happen if the handler is executed on another CPU in an SMP system. Still this is clearly suboptimal. This behavior turns into a real problem on an RT system, where the spinlock doesn't disable IRQs on the local CPU. Not acking the IRQ in the handler in such a setup is very likely to drown the CPU in an IRQ storm, leaving it unable to make any progress in the polling loop, leading to the IRQ never being acked. Fix this by properly acknowledging the channel 0 IRQ in the handler. As the IRQ status bit can no longer be used to poll for the channel completion, switch over to using the SDMA_H_STATSTOP register for this purpose, where bit 0 is cleared by the hardware when the channel is done.
