Brice has been helping me get hwloc working on an old Red Hat Linux 8
system.
We've appear to have gotten past the sched_setaffinity() prototype
conflicts, and I can build hwloc.
However, when I run "make check" there are 640 instances of the
following from test-hwloc-calc.sh.
pcilib: proc_read: tried to read 256 bytes at 0, but got only 64
Here is one manual run of hwloc-calc
$ ./utils/hwloc-calc --if synthetic --input "node:4 core:4 pu:4"
pu:22-47 --largest

I can run "lspci -vv" to get plenty of correct information and no such
messages.
So, this is not just a case of total libpci breakage.
Some system info:
$ cat /etc/redhat-release
Red Hat Linux release 8.0 (Psyche)
$ uname -a
Linux [hostname] 2.4.21-60.ELsmp #1 SMP Fri Aug 28 06:45:10 EDT 2009
i686 i686 i386 GNU/Linux
$ gcc --version | head -1
gcc (GCC) 3.2 20020903 (Red Hat Linux 8.0 3.2-7)
$ rpm -qf /usr/include/pci/pci.h
pciutils-devel-2.1.10-2
$ rpm -qf /lib/libc.so.6
glibc-2.3.2-4.80.8
FWIW:
This system is running a kernel from RHEL due to a lack of security
updates to RHL8.
So, it *is* possible that this is a mismatch between the kernel's /proc
and libpci's expectations.
If that is the case, of course, then hwloc can't possibly do anything
about it.
However "lspci -vv" does work, making me doubt this option.
Let me know what else might be needed to address this problem (or at
least determine if it is even a hwloc problem or not).
