aborting DMA

Postby notzed » Tue Aug 27, 2013 12:47 am

Is it safe to abort a dma operation? e.g. by either writing 0 enabled bit, or starting another dma transfer?

Scenario is a read-ahead pre-fetch that one knows is no longer needed.

Man, you have tough requests :D Sorry, that will likely cause a fatal crash. We'll think about a safe workaround.
