Issue/Bug Description:

Pop OS Kernel does not have binder_linux nor ashmem_linux enabled

Steps to reproduce (if you know):

Expected behavior:

Modules should be compiled as they are in the default ubuntu kernel, otherwise software like anbox cannot be utilized on Pop OS

Other Notes:

[KameiKojirou]

I'd like to second this.

[Fuseteam]

this seems to be duplicate of #39

[User8395]

This is a problem that I have had for a long time. Is there a link where one can download a kernel with those modules?

[KameiKojirou]

Right now you have to use an different kernel like https://xanmod.org/ that has support for those modules and at that point you still have to install and setup the modules.

[User8395]

at that point you still have to install and setup the modules.

Is there a guide on how to do that?

[KameiKojirou]

Sort of... but not really, I used this guide to do it for Waydroid a few months back, which I was able to make some adjustments when I got stuck to make it work. Ultimately it didn't do much for me anyways since Wayland still isn't there yet, Waydroid itself worked fine though. Just a heads up and a word of caution, this can mess up your OS and I don't recommend doing this unless you have a good understanding of how it all works. Otherwise you might end up with a borked OS.

Ok 

[JamiKettunen]

ASHMEM was dropped from mainline kernel in 5.18, but BINDERFS appears to be enabled even on the v6.2 kernel of the 22.04-based live ISO. I think all needed Waydroid options are now enabled by default?

[Fuseteam]

this can confirmed with grep -E '(MEMFD)' /boot/config-$(uname -r) for MEMFD (ASHMEM's successor) and grep -E '(BINDER)' /boot/config-$(uname -r) for BINDERFS

andrew@pop-os:~$ grep -E '(MEMFD)' /boot/config-$(uname -r)
CONFIG_MEMFD_CREATE=y
andrew@pop-os:~$ grep -E '(BINDER)' /boot/config-$(uname -r)
# CONFIG_ANDROID_BINDER_IPC is not set
