working on a Nokia N800 ---
Thanks to the good work by Barbieri, I've gotten oprofile installed and
running on my N800.
QUESTION/PROBLEM: Daemon now reports an "Invalid argument" problem
opening the output files:
oprofiled: open of
/var/lib/oprofile/samples//current/{root}//bin/busybox/{dep}/{root}//lib/libc-2.3.6.so/CPU_CYCLES.10000.0.all.all.all
failed: Invalid argument
This apparently happens many times .. the oprofiled.log contains 53K
lines, after a really brief run of a simple program.
ALSO - it has created quite a few of these files, notwithstanding the
error
HOWEVER - the files ALL have only null data -- in my case, size 2680
with all bytes 0
(same for all files!)
--> which, naturally, leads to an unhappy result with opreport,
which complains of "Invalid argument"..
---
NOTE - it did work for a while last week.
(I don't recall changing any configuration parameters)
I've tried reinstalling the SDK filesystem and oprofile things, but no
improvements.
Runs are made with /var/lib/oprofile -> /home/user/runs/oprofile, lots
of space available on main file system, empty "oprofile" directory to
start with.
Any suggestions would be most helpful....
