US 2023/0146364 A1 · PROCESS RUNNING METHOD AND APPARATUS

Abstract

A process running method and apparatus are provided. The method includes: receiving a process startup request; executing an executable file of a target process in a kernel based on the process startup request, to obtain first running function data that supports running of the target process in the kernel; migrating the first running function data to a functional safety partition to obtain second running function data, where the functional safety partition and the kernel are located at a same privilege layer; and running the target process in the functional safety partition based on the second running function data. According to the present disclosure, both the functional safety partition and the kernel are located at a kernel layer. In this way, during process running, a service at the kernel layer can be called without switching from a user layer to the kernel layer.

Dependent claims

A process running method, the method comprising:

receiving a process startup request, wherein the process startup request requests a start of a target process;
executing an executable file of the target process in a kernel based on the process startup request, to obtain first running function data that supports running of the target process in the kernel;
migrating the first running function data to a functional safety partition to obtain second running function data, wherein the functional safety partition and the kernel are located at a same privilege layer;
and
running the target process in the functional safety partition based on the second running function data.

2 more elements

A process running apparatus comprising:

at least one processor;
and
a memory coupled to the at least one processor and storing processor-executable instructions for execution by the at least one processor, wherein the processor-executable instructions, upon execution by the at least one processor, cause the at least one processor to perform the following operations:
receiving a process startup request, wherein the process startup request requests a start of a target process;
executing an executable file of the target process in a kernel based on the process startup request, to obtain first running function data that supports running of the target process in the kernel;
migrating the first running function data to a functional safety partition to obtain second running function data, wherein the functional safety partition and the kernel are located at a same privilege layer;
and
running the target process in the functional safety partition based on the second running function data.

5 more elements

A computer program product comprising a non-transitory computer-readable storage medium having stored thereon computer-executable instructions , when executed by a processor of an apparatus, cause the apparatus to perform the following operations:

receiving a process startup request, wherein the process startup request requests a start of a target process;
executing an executable file of the target process in a kernel based on the process startup request, to obtain first running function data that supports running of the target process in the kernel;
migrating the first running function data to a functional safety partition to obtain second running function data, wherein the functional safety partition and the kernel are located at a same privilege layer;
and
running the target process in the functional safety partition based on the second running function data.
