[PerfSuite-users] psinv can't list papi native events and hwpc-perfmon2.h can't be found

[<jj...@nu...>]

Hi Kufrin,

Recently I'm trying to build and install perfsuite-0.6.2. 
My platform is Thinkpad T43. Following is the CPU information dumped by
the /proc filesystem.

jiejiang@UT43:~/Perfsuite$ cat /proc/cpuinfo

vendor_id : GenuineIntel
cpu family : 6

bogomips : 1596.08
clflush size : 64
power management:

The operation system is Linux-2.6.27 with appropriate perfctr patch. 
Note that here I use a separate perfctr patch downloaded from perfctr
website, not the one included in the PAPI release.

We can confirm that perfctr works well using "perfex -i" command:
jiejiang@UT43:~/Perfsuite$ perfex -i
PerfCtr Info:
abi_version 0x05020501
driver_version 2.6.37 DEBUG
cpu_type 14 (Intel Pentium M)
cpu_features 0x7 (rdpmc,rdtsc,pcint)
cpu_khz 1995105
tsc_to_cpu_mult 1
cpu_nrctrs 2
cpus [0], total: 1
cpus_forbidden [], total: 0


After the above work, I built and installed PAPI-3.6.2.
The "papi_avail" and "papi_native_avail" commands output the
corresponding preset and native event lists separately.

After installing all other necessary enabling packages, such as
TCL/TK/Expat/tDOM, I managed to build and install perfsuite-0.6.2.
And basically, psinv/psrun/psprocess/psconfig commands works as
expected.

However, there are still some questions confusing me.
When issuing psinv with -e optio, it says:

jiejiang@UT43:~/Perfsuite/perfsuite-0.6.2$ psinv -e

The "-e" (or "--events") option is not supported on this system

The last line tells that the native event list is currently not
available. However, "papi_native_avail" can give the native event list
as expected. It seems that the source code of psinv relies on  libpfm
API to retrieve the native event list. 

Then does it mean that libpfm is a MUST requirement to get the support
for NATIVE event? 

Then I tried to configure and build perfsuite with "-with-pfm
PFM_CPPFLAGS=-I/usr/local/papi-3.6.2/include
FPM_LDFLAGS=-L/usr/local/papi-3.6.2/lib" options, which specify the
libpfm built with PAPI. (That is, papi built a libpfm internally.)
However, the building process failed with following message:

It seems that hwpc-perfmon2.h doesn't exist.
How to solve it?
