Nice work and Thank you.
But I would suggest use a LTS kernel instead of running behind latest kernel
www.kernel.org/category/releases.html
wiki.linuxfoundation.org/realtime/preempt_rt_versions
i feel either 4.19 or 5.4 kernel are most appropriate for longtime

@Sivaraj,

Our member Stormhold was having some install problems related to ethercat in a other topic, not for above release !!
He had given me his os download link, that pointed to a Gnipsel tutorial. I took the latest kernel and compiled it.
That's the reason above kernel is incuded.

I know the 4.19 kernel is very good. But when you go to the 5 series, in debian there are some library compatible issues with
linuxcnc. I have a workaround for this.

To my surprise the buildbot that i used with Mint works out of the box. If in the future the buildbot build's in the /opt/ dir, this would
be perfect.

If you want to have a 4.19 kernel or a 5.4 kernel. I can make a download release for this versions.
If you have any other suggestions, like preinstalled pyvcp packages. no problem.

My suggestion to the downloaders is : Collect your improvements, post them over here. Then in a few day's we can make a
next release.

For example. I can set the power-savings to off. Or other thing's that are annoying.

Hello @Grotius

I just installed Linux Mint 19 StormHold Rtos i
On a minix J50c-4 which has an RTL8111 which I wanted to use for ethercat
and the included intel BT/wifi 3168NGM.

Wifi works fine with the 4.15 kernel but doesn't in the RT kernel and it seems I can't just insmod or modprob the iwlwifi (because I saw that it wasn't set in the kernel config) /boot/config-5.11.4 -> CONFIG IWLWIFI is not set
I can't find the kernel sources nor the driver modules to get wifi to work-

inxi -i returns Device-2 Intel Dual Band .......... driver. N/A

So do I need to rebuild the kernell and modules or is there a quicker way?

Sorry to ask seems to me like a noobish question.. (in general I compiled the (RT) kernel myself andeverything, but what should I do here when it's "precompiled"?)

Seems the wifi works with th 4.15.22

Thanks for your nice work btw

Hi,

Nice pc !

I was wondering, can you buy them without a windows install?

I think rebuilding the kernel is a good solution, but a time consuming task.
If you succeed ,you could upload the kernel, then i can pick it up and put it
in the mint iso.

Thanks for your nice work btw
Ok, thanks.

For myself, i really like the linux-pro edition. I work with this version for a while now.

Dear Grotius,

I am sorry but I don't really understand a few things about the kernel image which
was provided as part of the Linux-Mint-Rtos-Stormhold-5.11.4

I installed with grub and after I compiled new versions of the kernel I can now compare both the version that you provided and the one which I compiled
but using the latency-histogram of the Mar25 compilation doesn't seem to be RT to me.. or at least not the fully preemptible version.

xx@xx-cnc:~$ uname -a
Linux xx-cnc 5.11.4-rt11 #1 SMP Thu Mar 25 13:15:14 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
- latency-histogram screen shot 16May2021-152



compared to the RT11+ I did compile as fully preemptible:
Linux xx-cnc 5.11.4-rt11+ #2 SMP PREEMPT_RT Sat May 15 23:06:08 CEST 2021 x86_64 x86_64 x86_64 GNU/Linux



But that is not all, I have tried with and without wireless but all my versions of the kernel with RT+ which I did (not sure why I do get a + sign) seem to make the GUI super slow (think 1 refresh every second when I move a window with the mouse), barely usable.
But I do get much better histogram tests. (see attachement screenshot)
With your kernel the GUI is behaving fine...
So it seems I only do get RT performance in the latency-histogram when the GUI is super slow :(

I checked the internet and I don't see anyone complaining on RT on the J5005 I did get one error in the dmesg though:

Warning: Spoiler!


Also I need to add the mac address for the ethercat still
Warning: Spoiler!


My experiments compiling RT Preempt on the raspberry 4 were not having such a slowing down effect so I wonder what can be wrong and also why is the kernel from 5.11.4RT not really having RT performance? (what was your config?)

Hello,

just to report I tested with 4.19.190-rt79 and it seems to be better overall.
CONFIG_PREEMPT_RT_FULL=y


The computer is responsive (windows and everything) and I think the kernel is RT... at least for the 1000 us it seems to hold better:

Dear Grotius,

I will summarise what I observed

1. Kernel 5.11.4 RT which came with image
- not RT
- no wifi
- GUI fast

2. kernel 5.11.4 RT + which I compiled
- RT
- wifi
- GUI super slow

3. kernel 4.19.190 RT
- RT OK
- wifi OK
- GUI OK
- no ethercat because it is an old kernel and ethercat from the image wasn't built against it.
