> Subject: [Dri-devel] 64-bit kernel, 32-bit user. Possible? Painful? I recall reading somewhere of a Linux (?SuSE?) box based on AMD's forthcoming 64bit x86 cpu, runing both a 32bit and a 64 bit program at the same time, so I'd say its possible.
I've no idea how this was being done ie was the 32bit backward compatibility mode being used for the 32bit program and the 64bit mode for the 64bit program. > So, I was thinking about some CPUs that are about to hit the market and > how they will interact with DRI.

I've nowhere near the knowledge of the interaction between kernel and userland to comment on that.
