University of Toronto ☛ Considering how much RAM system.slice and the kernel need
If you're setting a maximum, you need to know how much memory the system has. As covered in proc_meminfo(5), /proc/meminfo's MemTotal field gives you the total theoretically available system RAM after reserved bits and the kernel's very basic code and other memory usage. In practice the kernel is likely to need more RAM than this in normal operation, and figuring out where the memory is going can be complicated. Also, it's likely that in order to perform well, everything under system.slice will need more memory than simply the total program memory usage, because cgroup and thus systemd memory limits include things like the kernel filesystem cache.

Linux kernel 7.3 includes direct support for the Steam controller. Controlread 2026
Major updates to the HID subsystem were officially accepted into the Linux 7.3 kernel mainline, the key one being the release of the primary driver for the new Valve Steam gamepad. Controller model 2026. The device went on sale in May and was supported within the Steam client from its launch, later being integrated into the SDL library. Adding a specialized module to the kernel allows the manipulator to be used as a standard HID device in any system applications without the need to launch third-party libraries or the Steam client.
