If you install the kernel src debs, you can do a make menuconfig, which
will allow you access to the kernels fine tuning, and one of the option
buried in the menu's is to turn on a config option call preempt-rt or
preempt-realtime. This changes the IRQ handling to make the IRQ's be
handled much quicker at the expense of making other stuff wait a few
microseconds. preempt-realtime kernel
Hi Gene,
You've mentioned realtime kernel before as being faster(/better?), do
you have a goto link/article that explains it for a mostly uninformed
about kernel person?
There are other, even better ways to do this but this one disturbs the
rest of the system less, and it puts those operations in the users
workspace. All other methods become a portion of the kernel wom
And then there is RTAI, which gives a latrency of ~ 1/5th to 1/10th of RT-PREEMPT. But it
does not work on ARM :(

I can search this, but with the amount of
bias/wrong/propaganda you
end up with now from google searches, I figured I’d ask someone who
actually knows…
The confusion reigns heavily because the rt developer group is actually 2
or 3 parallel projects. All of which are working on getting the version
of the code they are working on good enough to become the core the
default build is based on. I am not an expert, I simply git clone a
version and if it works we've a winner, if not, tag a newer one and try
again. Development is moving at breakneck speeds Thanks,
Michael
