Hello,
I noticed many of my tests were bogus, as somehow my "-t NUM" argument
is not parsed properly on my target:
Linux efika 2.6.25.4-rt6 #10 PREEMPT RT Thu Jun 12 00:34:11 CEST 2008
ppc unknown
cyclictest 0.21 (with some extra argument printing added)
root@efika:~# /cyclictest -t 2 -n -p 50
threads = 1
started with interval 1000
T: 0 ( 1178) P:50 I:1000 C: 333 Min: 45 Act: 46 Avg: 49 Max: 100
root@efika:~# /cyclictest -t2 -n -p 50
threads = 2
started with interval 1000
started with interval 1500
on my x86/32 system the same happens (with -t 4 it defaults to 2
because it's a dual-core, with -t4 it works).
leon@witty:/tmp$ sudo ./cyclictest -t 4 -p 50
threads = 2
started with interval 1000
started with interval 1500
0.02 0.07 0.14 1/231 11760

T: 2 (11764) P:48 I:2000 C: 0 Min:1000000 Act: 0 Avg: 0 Max:-1000000
T: 3 (11765) P:47 I:2500 C: 0 Min:1000000 Act: 0 Avg: 0 Max:-1000000
At this moment I am puzzled, but I suspect the optional_argument handling.
