Change Details

This new flag obtains the processor number on which a process is running. Key parts of code and manual were borrowed from top. This change was only inspired by PR129965 as I didn't think that the patch attached to it was correct. While choosing between ki_oncpu and ki_lastcpu is an improvement compared to that, my main disagreement with that patch was the replacing of ki_estcpu with ki_lastcpu, which would render a part of the manual page definitely incorrect. ``` % ps -ocomm,cpu,cpu#,%cpu COMMAND CPU C %CPU tcsh 0 1 0.0 ps 0 0 0.0 tcsh 0 1 0.0 tcsh 0 0 0.0 make 0 1 0.0 make 0 0 0.0 sh 0 3 0.0 gmake 0 2 0.0 gmake 0 3 0.0 cc 0 1 0.0 cc 0 2 0.0 ```

This new flag obtains the processor number on which a process is running. Key parts of code and manual were borrowed from top. This change was inspired by PR129965. Initially I didn't think that the patch attached to it was correct -- it sacrificed ki_estcpu use for ki_lastcpu and I thought that the old functionality should be kept and the new one added to it. But I've since discovered that ki_estcpu is sched_4bsd-specific. It represents the same thing as ki_pctcpu, except ki_pctcpu is universal -- so "%cpu" uses it successfully. ``` % ps -ocomm,cpu,cpu#,%cpu COMMAND CPU C %CPU tcsh 0 1 0.0 ps 0 0 0.0 tcsh 0 1 0.0 tcsh 0 0 0.0 make 0 1 0.0 make 0 0 0.0 sh 0 3 0.0 gmake 0 2 0.0 gmake 0 3 0.0 cc 0 1 0.0 cc 0 2 0.0 ```
