Why were people asking me to test LXRT? Was it not working for other people, or just poor latency?

Re: [Emc-developers] LinuxCNC + LXRT (RTAI) results
Oh! Once RTAI is installed (both kernel and modules) and you're booted into your RTAI kernel, when you build LinuxCNC, you just force to use uspace on the ./configure line: ./configure --with-realtime=uspace This way, LinuxCNC will not build modules (.ko) against your kernel, but rather use LXRT. RTAI Debian packages: http://linuxcnc.org/dists/bullseye/base/binary-amd64/ Or: https://github.com/NTULINUX/RTAI/releases/tag/v5.3.2 For this test, I bumped the kernel to 4.19.261 and made a minor Kconfig change to prevent some possible build errors but I don't think this really matters. I also loaded the Debian Buster 4.19 kernel config instead of Stretch. I think new debs should be published though to reflect these changes as minor as it may be. I'll get around to it.

I can do more extensive testing. I wasn't sure what the problem was before that people were having but it at least runs for me.

Final note, sorry for all the emails, is that I compiled LinuxCNC myself using the following params: ./configure --with-realtime=uspace --enable-non-distributable=yes On LinuxCNC commit: c66ae6dfa56a4ce20f8ffa5e4e1aa55aabdf4bf5 Merge pull request #2084 from hansu/man-ascii-images Alec ___ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
Re: [Emc-developers] LinuxCNC + LXRT (RTAI) results
One of the things I keep having to do is run `sudo rmmod rtai_sched rtai_hal rtai_math` because `halrun -U` doesn't work and LinuxCNC/latency-histogram keeps saying RTAI is already loaded. While annoying, it _does_ work fine for me, and this is without having to add back in liblxrt to my RTAI tree.
