The differences in /proc files (attached are example files generated in my
alpha):
1. /proc/cpuinfo.
In proc_cpuinfo.c (part of the linux PMDA) 'refresh_proc_cpuinfo' updates
'cpunum' according to the first line in /proc/cpuinfo which is supposed to
include the word 'processor'. This line doesn't appear in the file on my
machine - therefore the program exits. Besides, the rest of the file uses
different titles so the values can't be parsed correctly.
2. /proc/net/rpc/nfsd.
In 'proc_net_rpc.c' 'refresh_proc_net_rpc expects a line with title 'rc' and
9 parameters. In the file on my machine these parameters are split into two
lines with titles: 'rc' & 'fh', and the 'fh' file includes 5 parameters
nly - 'fh_concurrent' does not appear. (three extra lines appear in this
file; the titles are: 'io', 'th', 'ra').

pcp-2.2.0-18 works fine on rh7.1-i386 with 2.4.x kernel. Which /proc
entry caused problems on linux-alpha and/or please send the patch?

>From SGI: no new features released to open source. However, we will be
maintaining the PCP open source release, tracking new linux releases
and continuing the gatekeeper role of accepting new features/patches
from the community. If you have new features that use PCP, such as gui
monitoring tools, new PCP PMDAs (agents) or whatever, we'd be more than
delighted to include them in the open source release!
