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.
