[9fans] Problem with outputing from kernel

I added some logs in /sys/src/9/port/proc.c for some tests of the scheduler, I want to see at what moments do real time processes take the cpu. I did that with simple prints with the intention of doing cat /dev/kmesg > someFile because all the prints are stored there.  The problem is that the

[9fans] print() in kernel space doesn't work like I would think

I was editing plan9's realtime scheduler in /sys/src/9/port/edf.c and was trying to add a print to log something, but print didn't show anywhere(or I am looking at the wrong place). It has some prints in source code already, with this define. #define DPRINT if(Dontprint){}else print And with Do

I finally read the article about asking questions, sorry if i was being rude or was waisting your time, wasn't my intention. And about the multi-core support, well I kinda moved away from it since I don't really need it, I was just wondering if i can disable it in an easy way for the measureme

Does plan9 have multi-core support? If it does, how does it manage it (what files/man pages/docs do I read). If it doesn't have, how would I implement it. -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T912e4838cb1a371f-M00dd91d9c0733c0
