Re: SMP and clock

Hi

This is my misunderstanding. Every core get self CP0 timer compare interrupt.

I found this log.

https://dmesgd.nycbug.org/index.cgi?do=view&id=3842

This kernel have other timecounter.

I also make timecounter by soc timer.

I have fixed problem.

I seem timcounter in tick.c is not compatible SMP.
