Subject: Nouveau fences?
Date: Sun, 28 Nov 2010 13:39:01 +0100	[thread overview]
Message-ID: <4CF24D65.4030008@shipmail.org> (raw)

Ben,

I'm looking at a way to make TTM memory management asynchronous with the 
CPU. The idea is that you should basically be able to DMA data to and 
from memory regions without waiting for idle, as long as the GPU has a 
means to provide operation ordering.

While doing that I looked a bit at the Nouveau fencing. It appears like 
waiting for fences is polling only (no irq to signal fences)? Is that 
correct?

/Thomas
