Kernel Profiling
Using readprofile
- Compile your kernel with `CONFIG_PROFILING=y`
- boot your kernel with profile=2 on the palo command line
- as root:
- `readprofile -r` # clears the profile counters
- run your test
- `readprofile -m /path/to/System.map -d /path/to/vmlinux > /tmp/profile.txt`
- you might want to sort the results using "sort -nr +2"
Using oprofile
- Compile your kernel with `CONFIG_OPROFILE=y` (or as a module)
- (to be written)
