The IL memory is unavailable when the processor goes to sleep, causing any involved DMA transfer to stall. The dma_transfer_wait() normally sleeps to save battery power, but this causes the whole system to freeze and never wake up. This change lets dma_transfer_wait() decide dynamically whether to sleep or spinlock. There is no concrete improvement over dma_transfer_noint() when using IL memory, but it makes dma_transfer() fully generic. Obviously the same goes for X and Y memory. |
