Thanks for reaching me out on my personal emails! My friend Runa is 
trying to make it Waydroid work by using the openSUSE's KMP but I guess 
since binder is present on the kernel in main branch, so ditching the 
KMP packages is good solution. Also, I have many tries to build the 
customized kernel but it failed and nothing helpful.

This is a real equipment that Waydroid needs to get work, but these 
config didn't exists in openSUSE Kernel.

Sounds like for the modules, we need to reach the openSUSE kernel 
maintainers and discuss about the binder integration. You can reach them 
by sending the binder integration issues on their mailing list 
(https://lists.opensuse.org/archives/list/kernel@lists.opensuse.org/).

It's okay! Don't worry about it. You can reach me everytime you're free.

That's it from me, reply it if you have an idea.

Hi again, Jim!

Got distracted by some other things, but I have a partial success to this!

Managed to build a custom kernel and after some messing with waydroid it 
seems to work just fine. You can find my work repo here: 
https://build.opensuse.org/package/show/home:shorberg:branches:Kernel:stable/kernel-source

Steps necessary to try out (coming from your packages):
1. Remove anbox-modules-dkms
2. install kernel-default from linked repo
3. boot to new kernel
4. run reinit waydroid `waydroid init -f <etc>`
5. for me it mounted /dev/binderfs with wrong permissions, fixed by 
`chmod 777 /dev/binderfs`


I'll continue to test it in the coming days to make sure all is working 
as it should.


Best regards,
Sebastian
