Let's just say I thought the concept of a 4000 mHz pentium was very
interesting. Especially when you consider that as a 14 year old (1967) I
was excited as he** to get a 6L6 to oscillate at 1 mHz. (And dont anybody
ask what a 6L6 is..... look it up :>)
Ok, so let me ask a dumb question.
What happens if I have a rtl thread dumping characters into a FIFO, and my
linux process doesn't query and empty the FIFO for a while, maybe for a long
while. Will the FIFO fill up and crash the system?
Also,
I want a rtlinux module to watch for the change of state of a digital input
and then flag the change of state to the linux process and also communicate
how much time has elapsed since the last change of state. Elapsed times
could be anywhere from 1500 msec to 6000 msec. I figure using a FIFO to
xmit a flag value (i.e. 0 or 1) and an elapsed time value (like the
nanosecond clock's change in count).
Am I on the right track?
Any suggestions as to how best to structure such an animal?
Thanks and regards,
Also, Victor, if you read this (or anyone else who may want to interject),
is it normal for RTL 3.0 to pass thru single user mode on it's way to level
3 and then level 5 sysinit? I had to reconstruct just exactly how my PATH
environmental variable was being built on a stock RTL 3.0 install, and it
turns out the first 4 entries are coming from /etc/rc.d/init.d/single. Is
this part of the plan (i.e. normal?)
Thanks again.
