   Apr 30, 2024 · Userspace lmkd also supports a legacy mode in which it makes kill decisions using the same strategies as the in-kernel LMK driver (that is, free memory and file cache thresholds). To enable legacy mode, set the ro.lmk.use_minfree_levels property to true. Configure lmkd. Configure lmkd for a specific device using the following properties.

   Nov 21, 2021 · Furthermore it is worth noting that the mentioned constants are relevant only for the LMKD legacy mode, e.g. in case of property ro.lmk.use_minfree_levels being set to true. Exploring the LMKD documentation you may find that there are at least 2 alternatives out there: using vmpressure signals; using PSI (pressure stall information) monitors

   How do I configure lmkd in Android?

   • Since Linux Kernel 4.12 the lowmemorykiller driver has been removed and instead userspace lmkd daemon performs these tasks. lmkd can be configured on a particular system using the following Android properties: ro.config.low_ram: choose between low-memory vs high-performance device. Default = false.

   What does lmkd do on Android?

   • Historically on Android systems memory monitoring and killing of non-essential processes was handled by a kernel lowmemorykiller driver. Since Linux Kernel 4.12 the lowmemorykiller driver has been removed and instead userspace lmkd daemon performs these tasks. lmkd can be configured on a particular system using the following Android properties:

   Does userspace lmkd support kill strategies?

   • Userspace lmkd supports kill strategies based on vmpressure events or PSI monitors, their severity, and other hints such as swap utilization. Kill strategies differ between low-memory and high-performance devices: On low-memory devices, the system should tolerate higher memory pressure as a normal mode of operation.
