s301, when the double operation system root domain is started, the resource control subsystem of the control group is installed.
The Control Group (CGroup) is a function of the Linux kernel, and may allocate a certain amount of system resources (such as CPU, memory, IO, etc.) to a specific Group of processes. CGroup itself is an infrastructure providing a function of performing packetization management on a process and an interface, and a specific resource management function such as IO or memory allocation control is realized by this function. These specific resource management functions are referred to as CGroup subsystems. The CGroup subsystem comprises a Memory subsystem for controlling the Memory, a CPU subsystem for controlling the process scheduling and the like.
When the intelligent terminal is started, after the Linux kernel is started, a Root domain initialization process is started. And when the Root domain is started, installing a CGroup resource control subsystem. For example, the CPU control subsystem is installed as follows:
mount cgroup none/dev/cpuctl cpu
s302, when the LXC starts the double operating systems, a corresponding control group is created for each operating system, and all process identifications in each operating system are configured into the corresponding control group.
For example, when the LXC starts the dual operating systems, respective CPU control groups are created under the directory/dev/CPU, such as vp1 and vp2, where vp1 corresponds to the first operating system and vp2 corresponds to the second operating system. Thus, two CPU control groups are created in the system;
mkdir/dev/cpuctl/vp1
mkdir/dev/cpuctl/vp2
the following configuration parameters are in each control group:
clone _ child cpu set, used to set whether a child CGroup will inherit the configuration of the cpu set of the parent CGroup. Wherein, the CPU sets allocates independent CPU and memory nodes for CGroup.
Procs, used to set up the thread group ID list for CGroup.
Rt _ period _ us, used to set the cycle of CGroup to obtain CPU resources, in microseconds.
Rt _ runtime _ us, used to set the time in microseconds that a task in CGroup can get the CPU resource the longest.
Share, used to set the relative value of the CGroup packet task to get CPU time. For example, if the cpu.share values of both control group a and control group B are 1024, then the CPU time allocated to the tasks in control group a and control group B is the same, and if the cpu.share value of control group C is 512, then the CPU time obtained by the tasks in control group C is half of that of a or B.
notify _ on _ release, which is used to set whether to execute release _ agent when the last process of the CGroup exits, and release _ agent is a path, and is usually used to automatically clean up the unused CGroup after the process exits.
tasks are used for configuring process identifications below the CGroup, and if one process identification is written into a tasks file, the process is added into the CGroup.
When the LXC starts the first operating system, all process identifications in the first operating system are written into a/dev/cpu/vp 1/tasks file, so that all processes in the first operating system are in a vp1 control group;
when the LXC starts the second operating system, all process identifications in the second operating system are written into the/dev/cpu/vp 2/tasks file, and all processes in the second operating system are in the vp2 control group.
In the embodiment, when the Root domain of the dual operating systems is started, the resource control subsystem of the CGroup is installed; when the LXC starts the dual operating systems, a corresponding control group is created for each operating system, and all process identifiers of each operating system are configured into the corresponding control group, so that the corresponding relation between the process identifiers and the control groups is established.
After the dual operating systems establish the corresponding relationship between the process identifier and the control group, when the foreground operating system and the background operating system are switched, the maximum resource allocation amount of the foreground operating system is configured to be a first resource allocation amount, and the maximum resource allocation amount of the background operating system is configured to be a second resource allocation amount, wherein the first resource allocation amount is larger than the second resource allocation amount.
For example, the allocation of CPU resources by foreground and background operating systems is controlled. When a foreground operating system and a background operation are switched, writing the CPU control group CPU, shares parameters corresponding to the foreground operating system into a first numerical value, and writing the CPU control group CPU, shares parameters corresponding to the background operating system into a second numerical value, wherein the first numerical value is larger than the second numerical value. For example, the first value is 1024 and the second value is 128. Therefore, the ratio of the foreground operating system to the background operating system to the CPU is 8:1, in this case, even if the background operating system abnormally occupies the CPU, at most 1/8 of the CPU can be occupied, and the use of the foreground operating system to the CPU is not influenced.
