Sure. As far as I could see the code is very similar. However, this:
rmesa->do_irqs = (0 &&
rmesa->dri.drmMinor >= 6 &&
!getenv("R200_NO_IRQS") &&
rmesa->r200Screen->irq);
looks like IRQs are turned off by default on R200. So my code wouldn't
be used. Is the reason for IRQs being disabled that the frame throttling
is not implemented properly or are there lower level problems with IRQs?
