Now I'm curious. Is it the case that every DRI1 driver *could be* a DRI2 driver with enough effort? Not talking about emulating hardware features. Patrick On Thu, Mar 1, 2012 at 1:46 PM, Dave Airlie wrote: > On Thu, Mar 1, 2012 at 7:25 PM, Connor Behan > wrote: > > On 01/03/12 01:36 AM, Dave A

There is one thing you didn't cover in your questions/myths: old hardware is often very limited by today standards, and removing it allows the code to become simpler (less fallbacks, more shared code, uniform code paths), as we can raise the assumptions of what a driver can and cannot do. And t

I am a first time mailing list joiner, long time user of exclusively free video drivers. I was very upset to see the DRI1 drivers removed from the codebase in August and I waited until now to complain because I wanted to see if the good changes like OpenGL3 would at least make it into the 8.0 r
