Re: UpTime() in IOKit ?

Hello everybody!

For replacing the UpTime:
I use now following code (in kern/clock.h) now :

//////////////////////////////////////////////////////////////////////
clock_get_time(&abstime);
absoluteTime_to_nanoseconds(abstime, &ns);
//////////////////////////////////////////////////////////////////////

When I said re-write our drivers I meant the heart of our drivers, the
protocol we use to communicate with the DSP.
the rest will be re-written.

Thanks,
Markus.
