I wonder what kind of resolution is needed. I'd love for timers to just be in "absolute time" using some fixed point arith, and then when the timer queue gets run you look at the current time and run all the ones that expired so far. That way you can make the HZ timer irq run this list, but if it's cheap enough and you then want higher accuracy, also the RTC clock, and potentially even some oddball thing like the idle loop or network interrupts for network timers, or video vsync irqs or .. or .. --FL5UXtIhxfXey3p5 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) iD8DBQFAywzGxULwo51rQBIRAr6pAKCQ5lbQcb2KBAuTUlUXqf6VK9z4MQCghAik GckB7Q8JAF27O8UPmwC3v6I= =SL9k -----END PGP SIGNATURE----- --FL5UXtIhxfXey3p5-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
