Used to be difficult, now, I think HZ are fully standardized around the kernel, you might find some broken drivers though.. *sigh* > P.s.: I'd like change HZ value to be able to measure process execution > time with, say, 0.001s precision. Could this be done is any other way? gettimeofday() has micro-second precision on 586+'s (uses rdtsc) Maybe you could do something with that. > P.p.s.: This should matter, I plan to use my modified kernel on > Celeron300+ class CPU, which would carry no other critical duties, > yet, will serve as low-loaded internet server. Should work fine, tbh I don't know why if you don't specify that you have over a pentium processor, it sets HZ to something lower, the processor can handle it... -- Mark Zealey (aka JALH on irc.openprojects.net: #zealos and many more) mark@zealos.org mark@itsolve.co.uk UL++++>$ G!>(GCM/GCS/GS/GM) dpu? s:-@ a16!
