README for procps package ========================= COMPATIBILITY This code is intended for use with Linux 2.0.xx and 2.2.xx. Both libc 5 and libc 6 should work. PS/TOP WCHAN FIELD In past releases, in order to get WCHAN output for ps, you had to have a psdatabase for each zImage kernel that you generated from the vmlinux unstripped binary with /sbin/psupdate. With this release, you should use the System.map automatically generated by Linus' makefile. 'ps' and 'top' will first use the contents of an environment variable "PS_SYSTEM_MAP" and then look for System.map files along the followin search path: /boot/System.map-V, /boot/System.map, /lib/modules/V/System.map, Here 'V' is the output of "uname -r" and looks like "2.2.0". Don't forget the dash! In those same locations, remove psdatabase* files.
