When you install LinuxCNC it will also install the correct kernel.
And that is not a real time kernel.

so .... sorry a misunderstanding of mine.
I went from memory and remembered some time ago you said that LMDE6 was already rt_preempt.... so all I had to do was download and install it..... the kernel I now have says preemt_dinamic.... similar to rt_ of ubuntu.. .. so I understood that I needed to download and install LMDE6 to have rt_preempt .... too easy, right?
Well clarified the fact you are saying that I have to install a patch right?
What do you recommend as a patch for a poor mini PC with N95 processor? I don't have big needs, 2ms of realtime would already be ok.
what sugget on thesse link can be ok? forums.linuxmint.com/viewtopic.php?t=407613
regards

That's fine for mesa hardware, but why the 2ms servo thread ?
It's not a pi**ing contest to get the lowest latency (sorry I'm from Australia and can sound a bit rude at times, but no harm meant). Don't get caught up trying the get lower & lowers latency if you are using an external hardware step generator. I think Pete for from Mesa said that trying to get latency under a certain figure does nothing to improve the system.
Although Miley Cyrus, like Danni Minoque, could mess things up. Just ask Jacques Villeneuve

No patches, no install, nothing, just install LMDE6, reboot, then
sudo apt update
sudo apt upgrade
sudo apt install linuxcnc-uspace
Nothing else.

@ tommylight .... precisely:
after install LMDE6 from linux mint sites need to do almost one of these two steps and you'll get the default real-time 6.1 kernel and you'll get the latest available from backports.
After you can use apt for install linuxcnc 2.9.0 or other packages using gedbi install only .... not test on 2.10 version ... but in 2.9.0, 2.9.1 and 2.9.2 only.
in my case isol cpu get bad result .... but set grub in these way:
GRUB_CMDLINE_LINUX_DEFAULT="-original paramters- intel_idle.max_cstate=0 processor.max_cstate=0 idle=poll"
I improve to 40% more or less the latency performances with sdev to 2,3 istead of 4,1 ...
And I'm not disable audio and vt-x from bios .....
@cornholio ... don't worry.... the fact is that I'm always under pressure.... sometimes I can't be sociable...once many years ago I had a helmet like that..... now one with the star like us navy.... but it's been on a shelf for a few years.
.... by the way, how come on dmax there are all these Australians looking for gold in the red lands? I've been seeing these things in the evening for two Saturdays already.... they've intrigued me.... not so much about the gold.... so much about digging up dirt in places that aren't exactly my Alps. Is these so usual or fashionable? or only a tv show?
P.S. terrible these new wisiwig on forum .....
