| |
intlat is a tool for measuring how long the kernel spends with interrupts disabled.
It is similar to the tool which Jun Sun at MontaVista announced a few days ago.
Salient differences:
- Jun's tool is for 2.2.14. intlat is for 2.3.99-pre3.
- Jun's tool is for UP. intlat is SMP-aware.
- Jun's tool is probably more accurate. I have some constant-time offsets which I'm not very motivated to tune.
The patch and documentation are available at http://www.uow.edu.au/~andrewm/linux/
