Ipipe-Patch for kernel version 5.4.23

Ipipe-Patch for kernel version 5.4.23

[Ralf Moder]

Hello everyone,
I need the kernel version 5.4.23 in an embedded linux project because of driver stuff but also the Xenomai extension. How big is the probability that an I-pipe patch for the 5.4 version will be released in the next 2 to 3 months?

Best regards


Ralf Moder

I would first of all say that it's >0. But beyond that, it depends on 
the architecture: x86 should be available on 5.4 in the next months with 
a probability >>50% as that will be my primary target for looking into 
how to move forward. ARM and ARM64 currently lacks a maintainer. If we 
are lucky, the base enabling via Philippe's dovetail queue will enable 
those more or less as well. But it will definitely take someone to take 
responsibility for those archs because my colleagues and I currently 
cannot invest beyond integrating contributions. There is also ppc32 
(which has a maintainer), but I suppose that this is not your target.

If you need this for arm I was going to try to port the ipipe to 5.4 in the
near future. Effort wise it shouldn't be too bad, but it all depends on how
much the upstream changes impact us.  What board are you targeting?

Jan, I can  help out maintaining the ARM ipipe.  We can talk offline if
you'd like.

I suppose that questions addresses Ralf (provided he runs on ARM).

As mentioned before, our tiny test lab currently contains for ARM a 
BeagleBone Black and QEMU instance.

That would be great, looking forward!

I don't think there will be a big impact, but that may depend on how
the RTDM core is ported over.

This is also my current expectation. Devil may sit in the details, though.

Worth to look into, but first prio would be getting things working, 
maybe initially with a bunch of additional patches on top of dovetail to 
keep Xenomai happy. In contrast to EVL, we will have to make sure that 
Xenomai remains usable with older kernels and their I-pipe patches.

The ESPRESSObin from marvell could be a good eval board for testing .If
you need it we can send you one. Or we can test new patches here in our
company.

This is an ultrascale? I’ve run the current ipipe code (4.19) on the
ultra96 without issue.

You are right. It is a Xilinx UltraScale+ ZU2CG.  For some reasons we need the 5.4 kernel version on this board.

The ESPRESSObin from marvell could be a good eval board for testing .If
you need it we can send you one. Or we can test new patches here in our
company.

It would be great if you could keep us up to date on your progress in
patching kernel version 5.4. If we can support you in any way, let us know.

In the CIP project, Cybertrust is currently working on a mainline 
backport of UltraScale patches to 4.19-cip. I have no overview about 
what they already support or can realistically achieve, but it may be a 
plan B. If there is interest, I can ask them for an update on the 
current status.

This could possibly be an alternative to a newer kernel version. It
would be great if you could actually find out which drivers are
currently backported there. We especially need the latest drivers
regarding PCI Express endpoint functionality.
