After presenting this week at XDC2011 Chicago about
TimeGraph, an open-source GPU command scheduler, and
PathScale's GPGPU run-tiume, Shinpei Kato has now taken to the Nouveau list with his proposal.
For those that were not at XDC2011 and wish to learn more, see
this message. Shinpei is proposing TimeGraph for this open-source Nouveau stack as being a DRM-compliant GPU command scheduler.
So far though the code has had
some negative feedback.
