[PerfSuite-bugs] Issue with papi3_p4.xml

[<edw...@ve...>]

Thank you for a very interesting and powerful tool!

I'm not sure if this is a bug or not, but on my system I 
had to disable the following line in papi3_p4.xml, v 1.4.2.3:

 <!-- ===================================================
       This does not work on my P4!!
  <ps_hwpc_event type="preset" name="PAPI_L2_DCR" />
  -->

When I run a program using psrun and the unaltered (original) XML file, I 
get this error message:

=> psrun -c papi3_p4.xml testCompare
psrun fatal error: hardware event not available

When I remove the PAPI_L2_DCR event, it runs fine.

I am using the following configuration:

- Red Hat Enterprise Linux, kernel version 2.4.21-20.EL, patched with 
perfctr-2.6.15
- PAPI 3.0.7
- PerfSuite 0.6.1
- gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-42)

The PerfSuite test suite did not have any errors. However, the PAPI 
tests did show initially fail a test with overflow3_pthreads.c, 
but I just ran them again and it now passes all of them. Maybe a recompile 
fixed it,
who knows?
