Well might NOT be over yet. It works fine here but Andy just tried this earlier today and he said:
"I tried running the abs.0 test in a loop with your new RTAI and 4.19.152. Unfortunately the old problem is still there, it locked the machine after 111 iterations. "
This script:
#!/bin/bash
sudo dmesg -c > /dev/null
rm ${HOME}/test-results/*
source ${HOME}/linuxcnc-dev/scripts/rip-environment
for PASS in $(seq 1 1000); do
echo starting pass ${PASS}
runtests ${HOME}/linuxcnc-dev/tests/abs.0
# uncomment these lines to make it crash less often
#DMESG=$(printf "${HOME}/test-results/dmesg.%04d" ${PASS})
#sudo dmesg -c > ${DMESG}
#cat ${DMESG} | cut -d ] -f 2- > ${DMESG}.cut
#sync
done

We need more testers. Somebody else ran it for 10K test cycles on an Intel i5 and it was fine.

Hello All,
The RTAI 4.19.152 component is mostly installed but causing problems with opening "kernel/ipipe/Kconfig.debug" for make olddefconfig and make menuconfig. Any help would be appreciated.

Why are you trying to open "kernel/ipipe/Kconfig.debug"?
Please post more details about what you are trying to do.

II am following the procedure for compiling the source.
It fails at "make olddefconfig" and "make menuconfig"
The original OS is a fresh install of Linuxcnc 2.8 buster vmlinuz-4.19.0-12-rt-amd64 Preempt RT
In order to get this far I needed to install
apt-get install bison
apt-get install flex
#Errors
root@debian-10amd:/usr/src/linux# make olddefconfig
scripts/kconfig/conf --olddefconfig Kconfig
lib/Kconfig.debug:438: can't open file "kernel/ipipe/Kconfig.debug"
make[1]: *** [scripts/kconfig/Makefile:69: olddefconfig] Error 1
make: *** [Makefile:554: olddefconfig] Error 2
root@debian-10amd:/usr/src/linux# make menuconfig

make[1]: *** [scripts/kconfig/Makefile:29: menuconfig] Error 1
make: *** [Makefile:554: menuconfig] Error 2
REBUILT again in different order.
1) Installed linuxcnc buster x64 ISO onto USB and dist-upgrade
2) Installed RTAI from source
3) Patched 4.19.0-12 reporting as 4.19.152-1 prior to patch and paused at "make olddefconfig"
4) Installed Linuxcnc Source as per linuxcnc.org/docs/devel/html/code/building-linuxcnc.html
5) Installed ALL dependencies like before
6) Ran make, no errors
7) Ran runtests, no errors
8) Continued with make olddefconfig, no error
9) make menuconfig, left defaults
10) make bzImage && make modules: FAILED looking for timeconst.h
11)locate timeconst.h NO RESULT
=== Installing RTAI ===
Commands marked with # specify root, commands marked with $ are user commands.
1.) Download the RTAI source
$ git clone https://github.com/NTULINUX/RTAI.git
2.) Patch kernel with IPIPE, in this case we use 4.19.152
# rm -rf /usr/src/000*.patch /usr/src/linux
# cd /usr/src
# wget https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.19.152.tar.xz
# tar xf linux-4.19.152.tar.xz
# ln -sfv linux-4.19.152 linux
# cp -aLv /path/to/this/RTAI-git-tree/ksrc/patches/v4.19.152/*.patch /usr/src/
# cd linux
# patch -p1 < ../0001*.patch
# patch -p1 < ../0002*.patch
# patch -p1 < ../0003*.patch
# patch -p1 < ../0004*.patch
# make olddefconfig
# make menuconfig
Configure to your needs
# make bzImage && make modules
# make install && make modules_install
3.) Update grub
Refer to your distribution documentation to do this. Generally for newer distros:
# grub-mkconfig -o /boot/grub/grub.cfg
4.) Configure, build and install RTAI (MUST BE BOOTED INTO YOUR NEW RTAI KERNEL)
$ cd ~/RTAI
$ ./autogen.sh
$ make menuconfig
Configure to your needs. You may also use ./configure instead.
For a full list of possible options:
$ ./configure --help
To build and install RTAI:
$ make
# make install
=== To create an RTAI .deb package ===
Remove any previously installed RTAI packages:
# apt-get purge linux-*-rtai* rtai-modules*
Notice: You must run the command above from inside a directory that
does not contain any .deb packages, otherwise you may see errors such as:
E: Unable to locate package linux-4.19.152-rtai_4.19.152-rtai-1_amd64.changes
$ cd ~/RTAI
$ ./autogen.sh
$ ./debian/configure 4.19.152 rtai
FIXME: In some cases (undetermined as of yet) you may need to use this
command instead:
$ ./debian/configure 4.19.152 rtai amd64
Now you are ready to build the actual package:
$ dpkg-buildpackage -uc -us
5.) LinuxCNC
Configure LinuxCNC:
$ cd linuxcnc/src
$ ./autogen.sh
$ ./configure
For a full list of possible options:
$ ./configure --help
Now build LinuxCNC:
$ make
Allow LinuxCNC to change permissions as needed:
# make setuid
To test LinuxCNC in a run-in-place environment:
$ cd ../ && . ./scripts/rip-environment
To run LinuxCNC latency test in said environment:
$ latency-test
Or to run LinuxCNC itself:
$ linuxcnc
For more information on building and installing LinuxCNC, please visit:
