PIO is used only for checking data path / codec settings. And underrun is very normal when PIO mode. Let's don't care about under/over run error when PIO case. Otherwise, 1) too many HW restart happens, 2) some sounds which need much data transfer can't play since it falls into error detection method which was created for DMA transfer
I've applied the whole series but I'm not thrilled with this one. I guess what you mean to say is that this is only used during bringup of a new platform in which case it's not that big a deal but otherwise then the usual thing with PIO is to implement FIQ support to keep the hardware full.
