Hi Morten and list,
I am current investigating HMP related stuff over TC2 platform, and find a strange issue. Here I have two module, both are creating fixed loaded thread, but one module would bound those thread to the cpu, while another don't do the bound operation.
[I test with linaro 2013.05 release to get below result] With setting A7/A15 to the same frequency, 1G, The result is: Bounded one: Five thread finished with 137s/137s/137s/138s/138s
unbounded one(With HMP related configuration enabled, which is the default one): Five thread finished with 138s/275s/275s/275s/275s
unbounded one(With HMP related configuration disabled): Five thread finished with 228s/229s/229s/229s/231s
So it seems to me, that current configuration don't make TC2 to run in its full performance. It worries me for it may downgrade the benchmark for somehow.
I haven't see into details, just post the result here to get your guys' feedback. While I get more detailed analysis, I would also post it here.
Thanks, Lei
