Let us switch to and focus on CXP. Actually https://github.com/hongzhanchen/xenomai.git is
not based on https://lab.xenomai.org/xenomai-rpm.git/log/?h=for-upstream/dovetail which
is base of CXP per my understanding. So Please forget it.
If you want to work on CXP and start related development and experience porting, maybe
https://github.com/hongzhanchen/xenomai-rpm/tree/dovetail/cxp is initial one. It is my own work
branch which I have integrated all patches from https://gitlab.denx.de/Xenomai/xenomai/-/tree/wip/dovetail
including Jan's patches and mine but it is still under development.
You can follow following steps to build it.
1. git clone -b dovetail/master git://git.evlproject.org/linux.evl.git
2. git clone -b dovetail/cxp https://github.com/hongzhanchen/xenomai-rpm.git
3. ./scripts/prepare-kernel.sh --linux=your_path --arch=x86 --dovetail=0001-null-patch.patch
4. cp hang-in-usleep_range.config .confg
5.make bzImage -j8
In addition , you can create your own 0001-null-patch.patch to work around script .
Following is mine.

Dear Philippe & Hongzhan,
I was trying to build xenomai3.2 and boot it in my desktop, here is what
1, git clone -b dovetail/master git://git.evlproject.org/linux.evl.git
2, git clone -b hongzhan/dovetail
3, ./xenomai-hongzhan/scripts/prepare-kernel.sh --linux=linux-evl
I found there are a lot of ipipe_xxx function calls in xenomai code like
ipipe_post_irq_root or IPIPE_NR_IRQS, which cause building failed.
As my understanding, dovetail is the replacement of ipipe, as a result,
ipipe function calls should be replaced by dovetail function calls. Did
i miss something or did something wrong?
