Re: [PerfSuite-users] psrun fatal errors: hardware event not available

Hi Rick,
Thanks for the zippy reply - much appreciated.
Just a suggestion - one of the tests that should run (maybe it does and I
missed it) is one that checks for the kernel version. It seems odd that NONE
of the tests fail (I thought that originally the threads test failed, but in
the output below, they pass). Seems like a pretty good test result for
something that won't run :)
I read the Linux Journal article which had no mention of the 2.6 kernel
prohibition and I must have missed the part where this was noted. In the
INSTALL, it mentions:
124 Currently, the latest 2.6.x release of perfctr is the best
choice of
125 versions for new installations of the driver. Please read the
126 instructions in the perfctr distribution carefully.
which implies that the 2.6 kernel is supported.
I can't argue with free SW, and I'm trembling with antici.....pation :) for
the 2.6 supporting version, but it might have been made clearer.
If there's currently a cvs/svn version of perfsuite, I'd be willing to give it
a try.
Also, the difference between root and user was only due to permissions
on /dev/perfctr. changing to a+r allowed a normal user to obtain the same
results.
Do you have any idea if the new version of PAPI will allow perfsuite to run on
2.6 (ie is the reason it won't run due to PAPI or due to perfsuite?)
FYI, below is the output of the perfsuite tests on my system.
