Hi Gerwin, If I use rumpkernel for my work, I will surely push the fixes as I go along. And suggest CI changes to the other repos. At this stage, I am not sure if I need the rumpkernel or if libsel4muslcsys[1] will be enough to run some basic apps on top. Best, Sid [1] https://github.com/seL4/seL4_libs/tree/master/libsel4muslcsys Thanks, Sid On Thu, Jun 9, 2022 at 3:47 PM Gerwin Klein wrote:

Hello sel4-devs, I came across the rumprun-sel4-demo apps [1] repo. There seems to be some bitrot as the kernel version keeps moving forward, But after moving the kernel back to 12.0 and some cmake fixes, I could get many apps(LevelDB, Redis, Memcached) to compile. Though "hello" ran fine, the few others I tried failed with various errors in the simulate step(such as page faults and invalid syscall number). I plan to debug these at some point, but I had a few questions about the setup before that.

1. Is this repo considered abandoned?

It is currently unmaintained, and in search of a maintainer. Anything that would bring it forward into working state again would be great!

If you're keen on getting some of the other apps working and keeping them working, I'd be happy to add more to CI if that helps.

Your other questions I'll have to leave to someone like Kent who knows more about that setup.

Cheers, Gerwin
