I have 2 QEMU-emulated Linux/MIPS systems.
On one hwloc-1.3.1 and 1.4 are working fine.
On the other I see strange "make check" failures.
Unfortunately they differ in both distro version and 32- vs 64-bit,
making it hard to pin down the cause.
The newer distro w/ the 32-bt kernel is OK:
$ cat /etc/debian_version ; uname -a
6.0.3
Linux debian-mips 2.6.32-5-4kc-malta #1 Thu Nov 3 05:21:00 UTC 2011
mips GNU/Linux
The older distro w/ the 64-bit kernel is failing:
$ cat /etc/debian_version ; uname -a
5.0.9
Linux qemu-hargrove-mips 2.6.24-etchnhalf.1-5kc-malta #1 Thu Oct 16
01:21:56 BST 2008 mips64 GNU/Linux
W/ hwloc-1.3.1 the failure is
FAIL: 256ia64-64n2s2c.output
with numerous differences in the diff output.
W/ hwloc-1.4 the failure is
FAIL: test-hwloc-distances.sh
with just one difference:
-Latency matrix between 16 PUs (depth 4) by logical indexes (below
Machine L#0):
+Latency matrix between 16 PUs (depth 3) by logical indexes (below
Machine L#0):
BUT, there is also a bus error that is being reported as a PASS:
Machine (247MB) + PU L#0 (P#0)
./test-hwloc-ls.sh: line 50: 7061 Bus error $ls
$tmp/test.txt
PASS: test-hwloc-ls.sh
At the moment my suspicion falls on the compiler, as I can't see how a
failure of 256ia64-64n2s2c.output could be h/w dependent.
