lmkd can be configured on a particular system using the following Android
properties:
ro.config.low_ram: choose between low-memory vs high-performance
- `ro.config.low_ram`: choose between low-memory vs high-performance
device. Default = false.
ro.lmk.use_minfree_levels: use free memory and file cache thresholds for
- `ro.lmk.use_minfree_levels`: use free memory and file cache thresholds for
making decisions when to kill. This mode works
the same way kernel lowmemorykiller driver used
to work. Default = false
ro.lmk.low: min oom_adj score for processes eligible to be
- `ro.lmk.low`: min oom_adj score for processes eligible to be
killed at low vmpressure level. Default = 1001
(disabled)
ro.lmk.medium: min oom_adj score for processes eligible to be
- `ro.lmk.medium`: min oom_adj score for processes eligible to be
killed at medium vmpressure level. Default = 800
(non-essential processes)
ro.lmk.critical: min oom_adj score for processes eligible to be
- `ro.lmk.critical`: min oom_adj score for processes eligible to be
killed at critical vmpressure level. Default = 0
(all processes)
ro.lmk.critical_upgrade: enables upgrade to critical level. Default = false
- `ro.lmk.critical_upgrade`: enables upgrade to critical level. Default = false
ro.lmk.upgrade_pressure: max mem_pressure at which level will be upgraded
- `ro.lmk.upgrade_pressure`: max mem_pressure at which level will be upgraded
because system is swapping too much. Default = 100
(disabled)
ro.lmk.downgrade_pressure: min mem_pressure at which vmpressure event will
- `ro.lmk.downgrade_pressure`: min mem_pressure at which vmpressure event will
be ignored because enough free memory is still
available. Default = 100 (disabled)
ro.lmk.kill_heaviest_task: kill heaviest eligible task (best decision) vs.
- `ro.lmk.kill_heaviest_task`: kill heaviest eligible task (best decision) vs.
any eligible task (fast decision). Default = false
ro.lmk.kill_timeout_ms: duration in ms after a kill when no additional
- `ro.lmk.kill_timeout_ms`: duration in ms after a kill when no additional
kill will be done. Default = 0 (disabled)
ro.lmk.debug: enable lmkd debug logs, Default = false
- `ro.lmk.debug`: enable lmkd debug logs, Default = false
ro.lmk.swap_free_low_percentage: level of free swap as a percentage of the
- `ro.lmk.swap_free_low_percentage`: level of free swap as a percentage of the
total swap space used as a threshold to consider
the system as swap space starved. Default for
low-RAM devices = 10, for high-end devices = 20
ro.lmk.thrashing_limit: number of workingset refaults as a percentage of
- `ro.lmk.thrashing_limit`: number of workingset refaults as a percentage of
the file-backed pagecache size used as a threshold
to consider system thrashing its pagecache.
Default for low-RAM devices = 30, for high-end
devices = 100
ro.lmk.thrashing_limit_decay: thrashing threshold decay expressed as a
- `ro.lmk.thrashing_limit_decay`: thrashing threshold decay expressed as a
percentage of the original threshold used to lower
the threshold when system does not recover even
after a kill. Default for low-RAM devices = 50,
for high-end devices = 10
ro.lmk.psi_partial_stall_ms: partial PSI stall threshold in milliseconds for
- `ro.lmk.psi_partial_stall_ms`: partial PSI stall threshold in milliseconds for
triggering low memory notification. Default for
low-RAM devices = 200, for high-end devices = 70
ro.lmk.psi_complete_stall_ms: complete PSI stall threshold in milliseconds for
- `ro.lmk.psi_complete_stall_ms`: complete PSI stall threshold in milliseconds for
triggering critical memory notification. Default =
700
lmkd will set the following Android properties according to current system
configurations:
sys.lmk.minfree_levels: minfree:oom_adj_score pairs, delimited by comma
- `sys.lmk.minfree_levels`: minfree:oom_adj_score pairs, delimited by comma
sys.lmk.reportkills: whether or not it supports reporting process kills
- `sys.lmk.reportkills`: whether or not it supports reporting process kills
to clients. Test app should check this property
before testing low memory kill notification.
Default will be unset.
