of the isolcpus argument is generally a one time thing if done correctly.
This distro, downloadable from wiki.linuxcnc.org, was assembled by the
LCNC people based on ubu 10.04.4 LTS, uses grub 2, but has its own grub
config for LCNC in /etc/grub.d.
If you rerun the grub configurator, that is preserved only for the special
RTAI patched kernel. I am running a much later 3.16.0 ATM because that
RTAI patched kernel is not PAE, meaning I'm a gigabyte into swap in 3 days
uptime, no such problem with 3.16.0, so I am restricted to running only
the simulator versions. Nice to troubleshoot gcode with, but incapable of
carving metal.
The stuff running on core 0 may lag, but LCNC
keeps chugging along on
the isolated core 1.
You folks really should take advantage of the isolcpus command for
your latency critical work. The gui's may not keep up, but the
sound should.
I agree that would make a lot of sense. I think there are some other
tools that could do some of these things too. However, many people
even in linux audio rely on OOTB setups. It is hard for a distro to
imagine what setup the user might have to make the very best use out
of it. Also, those who put distros together often do not have the
knowledge to set something automated up either. So this will have to
start will people who are willing to take the time to customize a
system to use these ideas. The one problem with the older Atoms is the GPU. It
does work ok, but
it is always (in Linux) configured for at least two screens (a direct
LCD seems to be the exception) one of which normally gets set up to
not show (but still uses memory).
I wasn't aware of that, and have the milling machine configured for 8
"workspaces" and the lathe set for 4. Generally that is sufficient.
The latest ones have a different
gpu, but I do not know if it is open either.
The D525MW's I have are later production in ARK shoeboxes, using the i915
driver. It seems to be adequate. Capable of driving the older LCD
monitors like I use for space considerations.
I put one in my wife's
computer, but it is not keeping up with her main (mostly graphics)
use. So i will be using it as a headless audio board after I get her
another one (with an open GPU like my son has).
