Subject: [ECOS] CPULoad on i386
Date: Fri, 04 Sep 2009 10:11:00 -0000 [thread overview]

Hi,
I`ve been trying to get an idea of my applications performance (was < 10% on windows machine) and have been running into problems with the cpuload feature.
cyg_cpuload_get returns zero for all the fields and I`ve debugged into the code and fouind the calibration value is (around) 0x64.
Shouldn`t the high priroty idle thread run more than ~100 times during 100ms? I would expect a massive figure here..(also 100 times in 100 ms sounds a bit like I executed per ms)
I`ve tried this with both my custom repository and a default "i386 with 8139" repository and the results are the same. I`ve removed network cards, ensured a single process CPU (AMD Sempron 2800+) without power managament is used and call the functions at the very start of main()
Anyone got any ideas?
James
