Abstract

The present application discloses a method for upgrading a driver program, including: loading and starting a second sub-driver into the memory under the control of the first sub-driver of the driver program; sending the first sub-driver to the third sub-driver The received request is switched to be sent to the second sub-driver; and the third sub-driver is uninstalled. In the method for upgrading the driver, when the driver is upgraded, the hot upgrade of the driver is realized through the smooth transition from the old version of the driver to the new version of the driver, so that the driver can maintain a normal working state during the upgrade process. , will not interrupt the data services provided to the outside world, and the reliability is higher.

Description

technical field [0001] The application relates to the field of driver programs, in particular to a method for upgrading driver programs. The present application also relates to a device for upgrading a driver program and an electronic device. Background technique [0002] A driver is a functional program between hardware and software. It is a special program that enables hardware and software to communicate. It is used to provide an interface for software to access hardware. Only through this interface can software control the work of hardware devices. In practice, in order to meet the needs of applications and other aspects, the corresponding driver will be upgraded. [0003] At present, when the driver is upgraded, the application software is notified to stop using the driver, and then the current driver is unloaded by calling the system function, and then the new version of the driver is loaded, and the hardware is reset and initialized according to the new version of th...
