Timer resolution

<< < (3/5) > >>

Arslan S.:
that's the latency between actual and expected sampling time values in us (micro seconds)
what is computer specs you are running ?

Tuftec:
If I run the cyclictest with no options it reports that the High Resolution Timers not available.

System is embedded system on chip.
1Ghz clock, equiv to 586 style processor. 600Mhz RAM bus speed.

Arslan S.:
i think your system does not have hr timer, it is not the tiny core linux kernel

curaga:
Wait, one of the Xcore86 / DMP / Sis etc cheapos? I really doubt they support better timers, high res ones need hardware support.

Rich:
Hi Tuftec
It does not look promising, but as an act of desperation you can try  hpet=force  or one of the other
hpet boot codes list here.
