I am trying to run a command in realtime mode just to see
if it behaves any different as far as timings are concerned.
Man page says:
CHRT(1) Linux User’s Manual CHRT(1)
NAME
chrt - manipulate real-time attributes of a process
SYNOPSIS
chrt [options] prio command [arg]...
chrt [options] -p [prio] pid
So, I tried the first example instance above:
$ sudo chrt 0 ./freq -s120 -u0 -r
chrt: failed to set pid 0's policy: Invalid argument
Hmmm. I thought the arg after chrt should be the value of the priority,
since options to chrt are optional!!!
Another broken utility???
Soo I tried:
$ sudo chrt ./freq -s120 -u0 -r # i.e. no value for priority
chrt: failed to set pid 0's policy: Invalid argument
Anyone tried this before? Any clues?
