Consider replace systemd with libuv? #419

Closed Thor-x86 closed 1 month ago

Thor-x86 commented 1 month ago

Before I'm working on the PR, I need to know why not use libuv to poll libinput with event loop? Using systemd on most embedded system is like driving a bus to a picnic site where the only passenger is spouse and the rest seats are left empty. In our case, we included around 25 systemd binaries with some unrelated services including systemd-machined, but we only need sd-event. This is a huge resource waste for embedded system. If you think it's okay to replace systemd with libuv, I'm going to continue finish the PR. Thanks!

There is no particular reason and if I remember correctly, weston also uses systemd, which was one of the reasons.

Yes, it would be great if your PR could reduce the dependencies on the necessary binaries.

Alright, I'm working on it. I'll assume libuv is only required if systemd is not exist. Please let me know if you need something

Thank you.

Nothing comes to mind. Currently, libsystemd is only used for DRM backend and poll libinput. See also: https://github.com/sony/flutter-embedded-linux/wiki/Installing-dependent-libraries#only-when-using-drm-backend
