* Add opt-in zRAM compression for the Steam client while a game runs A "zRAM compression" toggle under Steam > Settings > Session, below "Keep downloads running". Off by default, kept once set, and disabled on devices without swap or with a kernel older than 5.4. When on, the session watches for Steam's reaper. 20 s into a game the client and its web helpers page their private anonymous memory out to the device's zram with MADV_PAGEOUT from inside their own process (libblsession zram.c, SIGURG), again every 5 minutes, and read every swapped page back once the game exits. No root is needed: only a process itself may do this without CAP_SYS_NICE. With the toggle off nothing is installed or started. RedMagic NP06J, Palworld: Steam's resident memory fell from ~1.7 GB to ~1.1 GB with ~560 MB in zram, available memory during play rose by ~0.5-0.8 GB, and ~2 MB was left in zram after the read-back. * Turn zRAM compression on by default below 12 GB of RAM Until the toggle is changed, it follows the device: on when the kernel supports it and the device has less than 12 GB of RAM, read from the advertised memory size on Android 14+ and from total memory before that. Turning it off is kept. --------- Co-authored-by: xXJsonDeruloXx <danielhimebauch@gmail.com>
