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/ -- -akpm- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.rutgers.edu Please read the FAQ at http://www.tux.org/lkml/
