" From: Meelis Roos <mroos at linux.ee>
" Today we have (3D) vector capable graphics cards that emulate the 2D
" part using 3D engine, multiple applications can use the card without
" lockup or isolation problems. Basically we have a DMA pipeline to the
" card, using IRQ-s for flow control. We can mostly take the DMA pipeline
" directly to the applications using a thin kernel driver and userspace
" library, and do the acceleration stuff in another userspace library. No
" need for graphics server because of IPC latency and memory latency of
" passing data and control.
saw some chip stats a few years ago.
the biggest chips were leading-edge gpus. big honking powerful cpu
chips had only half the gate count. proliferation of cpus per chip
may have changed that... but i wouldn't be surprised if gpus were
still well out in front.
