Compiling xenomai-linux 5.10.83

Compiling xenomai-linux 5.10.83

[Andrew]

Hi,

I am trying to work on a project that is easiest to accomplish if I base my changes on a product that is based on the mainline linux kernel 5.10.83.

I will explain the steps I took to get to the version I am interested in:

- I checkout the v5.10.y-evl-rebase branch of https://source.denx.de/Xenomai/xenomai4/linux-evl.git

- I look in Makefile to see the kernel version is at 5.10.99
- I run make menuconfig to see what options I need to set to enable the EVL kernel

- Processor types and features ---> EVL real time core
- I then look at git log to find the hash just before the integration of 5.10.84

- e6edaf2677939a8cf57e9152b1ab07b80f83fa11
- I assume this would be the latest set of changes that allow xenomai to work with the mainline kernel 5.10.83
- I run make menuconfig

- We no longer have any options (that I can see) to configure the EVL core

Does my approach make sense to get the xenomai version that was compatible with the mainline kernel 5.10.83?

I understand you are all busy, but any advice/direction/web pages that describe what I need to do would be appreciated.

Thanks,

Andrew

You may want to checkout tag v5.10.83-evl1-rebase based on v5.10.y-evl-rebase branch.

That won't work because this is a rebase branch, meaning that EVL sits
on top of the mainline tip, therefore #e6edaf26 is below the first
commit introducing the EVL code.

There are several ways to do this, but in your case, the easiest would
be to check out this tag: v5.10.83-evl1-rebase. There is no additional
EVL code between v5.10.83-evl1-rebase and v5.10.99-evl1-rebase.

Hi,

Thank you for your response, Phillippe and Hongzhan, that was exactly the solution I needed.

Cheers,

Andrew
