Subject: [9fans] Problem with outputing from kernel
Date: Wed, 4 Oct 2023 07:18:23 -0400	[thread overview]

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 flow of output just randomly stops at times and continues(only once by test) and i lose some of the output  which is really important. Any ideas why?

Also I was doing with tail -f /dev/kmesg in the background and without that /dev/kmesg loses the start of output up to some random moment where it shows it. Could the problem be that i have too many outputs?
