You're right, this check is probably redundant. The VBLANK ioctl will return an error if IRQs don't work. :-| > > Or would you prefer having another option "use_vblank_irqs" or more > > general "use_hw_irqs" and maybe rename "use_irqs" to "use_sw_irqs". > > I'd like to drop VBLANK_FLAG_NO_IRQ altogether as it doesn't make sense > to me - vblank throttling and software interrupt emission are orthogonal > concepts. They are, therefore I suggested using two different options. So the user can decide that a specific application shouldn't use vblank throttling. Then maybe the flag is misnamed. Something like VBLANK_FLAG_DISABLE would be more appropriate. ------------ __\|/__ ___ ___ ------------------------- Felix ___\_e -_/___/ __\___/ __\_____ You can do anything, Kühling (_____\Ä/____/ /_____/ /________) just not everything [EMAIL PROTECTED] \___/ \___/ U at the same time. ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
