motherboard for linuxcnc uspace + mesa 7i80hd

Witch motherboard for linuxcnc uspace + mesa 7i80hd

Asrock J5005-ITX
or
Asrock J4105M (microATX)

?

They are both intel and pretty similar performance wise so I dont think it would make much difference.

7i80hd has some requirements from ethernet card ?
For example works with
Realtek RTL8111H / Realtek RTL8111E
?
Also for touch screen what i must see before order ?

i got Asrock J4105M (microATX) because has parallel + 2 serial
also 30euros cheaper from j5005-itx .
When i receive i will inform for jitter and if it is suitable for linuxcnc.

I got asrock J4105M but intel onboard gpu with stock preempt-rt kernel does not work
needs kernel >= 4.18 to work.

Iam building new kernel now
so in 3 hours after compiling finish i will know..

Yes, I'm running 4.16 on a couple of test machines

(even 4.18 works though I would not suggest 4.18 for general use yet)

ok iam building it in debian stretch(stable) with linuxcnc 2.7.14 installed from linuxcnc.org repo..
I have tried 4.18 but rt patch fails to aplied.

I have tried to install 2.7.14 from linuxcnc.org repo to debian sid but fails because is missing 1 depedency

You may have a build script error with 4.18

It does build and make a working kernel:

missing dependencies are to be expected (and fixed)

When i apply patch to 4.18.5 it fails here
$ xzcat ../patch-4.18-rc8-rt1.patch.xz | patch -p1

I would not expect a patch set for 4.18-rc8 to apply to 4.18.5
