The invention discloses a microkernel-based hardware device driving system and its driving method. The system includes a bottom driver layer, a device abstraction layer, a consistent API layer, a remote procedure call layer and a device manager; the bottom driver layer is used to realize Various operations on the device; the device abstraction layer is used to provide the encapsulation interface; the consistent API layer is used to re-encapsulate the encapsulation interface; the remote procedure call layer is used for the remote procedure call communication between the encapsulation interface and the user interface; The device manager is used to manage device information, manage device operation information and manage device drivers. The hardware device driving method of the present invention greatly reduces the complexity of the driver code, improves the readability of the driver code, reduces the driver development time of the driver developer, and finally achieves the effect of reducing the research and development cost.
Description
technical field [0001] The invention belongs to the technical field of device driving, and in particular relates to a microkernel-based hardware device driving system and a driving method thereof. Background technique [0002] In Linux, different driver implementations are designed for different types of devices. This kind of driver implementation is to extract the same parts of the same hardware drivers from different manufacturers and implement them yourself, and then leave the different parts for interfaces to specific driver development engineers. To achieve, so as to achieve the standardization of the drive. Some systems for unified management of system resources are also designed in the kernel. These systems enable the kernel to coordinate and allocate resources used by various drivers in a unified manner, thereby ensuring the stable and healthy operation of the system. [0003] It can be seen from the above description that the driver framework of the kernel is some ...
