Hello everyone,
I am currently working on a program that I think could make use of some
of the things the rtlinux project provides.
I've written a small program (an accuracy test to see how accurate
linux will deliver signals to me). It records the current time (t0),
sets a timer via setitimer() for a random amount of time (t1, anywhere
from 0 to 1 second), waits for the signal to arrive, and compares when
the time SHOULD have arrived (by adding t0 and t1) to when they DID
arrive (tf).
This test works great with the normal linux kernel under low-load
circumstances. There is accuracy sufficient for what I'm doing (a music
program, so accuracy counts). However, whenever there is disk I/O, or
program loading, or anything interrupt driven (IDE disk I/O is interrupt
driven, right? Now I might just be talking out of my arse... this gets
into details which I don't understand yet)... there are SIGNIFICANT
delays. I am under the impression that the rtlinux project offers a
solution to this problem.
Right now all I want to do is translate my program into the appropriate
rtlinux calls. However, I haven't found the equivalent of setitimer()
in the man pages. Is there one, or is there an entirely different
mechanism for all this? And is there some tutorial where I can learn
about all this?
Many thanks in advance,
-Kiran Garimella
