| |
hello, I am playing around with CPU_NOTIFIER_ERROR_INJECT and am noticing that
example 2 # modprobe cpu-notifier-error-inject cpu_up_prepare_error=-2 # echo 1 > /sys/devices/system/cpu/cpu1/online bash: echo: write error: No such file or directory
is not working for me, or atleast is not showing me any info that it is working.
the other proceedure does work:
example 1 # modprobe cpu-notifier-error-inject cpu_down_prepare_error=-1 # echo 0 > /sys/devices/system/cpu/cpu1/online bash: echo: write error: Operation not permitted
dmesg shows: [ 2427.924405] Injecting error (-1) at cpu notifier [ 2427.930569] _cpu_down: attempt to take down CPU 1 failed
any ideas on what I need to do or is this working, and am I not seeing anything in dmesg?
