I am super excited about this driver. I worked on the early drm first at Precision Insight and then at VA Linux Systems, and having hardware validated command streams seperate for each process is just such a huge deal for performance. I wrote some proof of concept code awhile back that I posted to the Mesa dev list for doing something like this without hardware support, and based on my limited testing it would be a huge improvement in dma throughput. Its nice to see something like this happening finally, I think it is a path to getting a secure and highly performant driver. We have always had to make security tradeoffs with performance in Linux land, now we actually might have the infrastructure to get a chance at matching or beating Windows performance. Terribly exciting.
