I've got a D525mw, and every once in a while it'll throw up an RTAI error.
At first I thought it was the update manager, but turning that off did not help.
my BASE_PERIOD is 30769; I wonder if that is way off the mark? Anyone with an
Intel D525MW willing to tell me what you use?

I found that my D510 was very reliable for latency unless I had the
webcam plugged in.

Good - I'll try your BASE_PERIOD - (read on)

Yes - e.g., top shows 1 processor. When running a Gcode program, it's averaging
68% idle.

top always shows one processor unless you press the "1" key.
Even with Isolcpus top should show 2 processors, but one shold appear
completely idle.

Thank you. I'll check this tonight.

Me again;
Ok - top (with key press "1") shows 2 cpus, one idle ALL the time.
With the LinuxCNC 2.5 "release-version", downloaded about a month ago, The
"taskset" is not getting called as it should be.
So, LinuxCNC runs on CPU0, along with everything else.
Now to find out where that taskset

I _think_ that means that RTAPI is running on there, but top can't see it.

Nope - (being blunt) Remember that that isolcpus is theoretically set properly
by grub2.
1) start linuxcnc 2.5.0 from command line.
f50mm g1 x0 y0 z0
top shows:
cpu0 64% system 35% idle
cpu1 100% i

Shouldn't that be rtai? Doesn't linuxcnc include all the userspace stuff too?
I have never seen anything rtai show up in top (or htop, having just
installed that) and I have been assuming it was running invisibly in
the appa

Ah - I now understand what your thinking is.
I really don't know - but your comment makes sense - I was throwing the whole
of linuxcnc over to cpu1, not just the rtai section.
Right now my little KX1 is running a test with a BASE

It looks like I was wrong, but (if I'm correct this time!) running linuxcnc +
the RTAI stuff in core1 on my little D525MW seems to do the job quite well.
It's been running a program for a couple of hours right now, and no issues.
