[SOLVED] How to enable cgroups in Linux

Issue

In Linux I think there is a mechanism to kill the application.

I want to know what is in the condition that will cause an application to be killed?

For example, I think that there are insufficient memory, a certain number of application launches, and so on.

Control group (cgroups) which supported by Linux kernel permitting to limit resource used for an application. (memory, bandwidth, disk, …). Once a particular app exceeds the permitted resource, it will be automatically killed.

How to enable it?

Solution

Make following modification to do_configure_append() in linux-kernel.bb.

# cgroups
kernel_configure_variable CGROUPS y
kernel_configure_variable CGROUP_FREEZER y
kernel_configure_variable CGROUP_PIDS y
kernel_configure_variable CGROUP_DEVICE y
kernel_configure_variable CPUSETS y
kernel_configure_variable PROC_PID_CPUSET y
kernel_configure_variable CGROUP_CPUACCT y
kernel_configure_variable PAGE_COUNTER y
kernel_configure_variable MEMCG y
kernel_configure_variable CGROUP_SCHED y

kernel_configure_variable NAMESPACES y

# overlay fs
kernel_configure_variable OVERLAY_FS y
