Abstract

The embodiment of the invention provides a hardware abstraction layer multiplexing method and device, an operating system and device. The method comprises the following steps of obtaining a sample; responsive to hardware operation instructions, calling a first application program interface (API) in a first operating system side virtual hardware abstraction layer (HAL) by a first process of the first operating system, sending a calling request of the first API to a second operating system through cross-process communication, wherein the configuration of the first API in the virtual HAL corresponds to the configuration of the second API in the second operating system side HAL, and the configuration of the first API in the virtual HAL corresponds to the configuration of the second API in thesecond operating system side HAL. The virtual HAL is set at a first operating system side, so that the calling of the API in the virtual HAL by the first operating system side can be transmitted to the second operating system side through cross-process communication, the multiplexing of the HAL of the second operating system side by the first operating system is realized, the realization is convenient, and the method can be suitable for any different operating systems.

Description

technical field [0001] The invention relates to the technical field of operating systems, in particular to a hardware abstraction layer multiplexing method, device, operating system and equipment. Background technique [0002] When terminal equipment manufacturers such as mobile phones develop terminal equipment, they usually develop a set of hardware abstraction layer (Hardware Abstraction Layer, HAL for short) only for one operating system. If another operating system needs to be supported in the terminal device, the most efficient method is to reuse this set of HAL. However, the basic C libraries based on two different operating systems are often different, which makes it difficult to adapt to the reuse of HAL. [0003] At present, the most commonly used adaptation solution is to directly use the Libhybris mechanism to load the HAL, which can realize the reuse of the same HAL between the Bionic-based Android operating system and the Glibc-based operating system, where Bi...
