Abstract
An initialization process in a device driver is provided. The device driver runs in a learning mode to read and store the initialization parameter that it needs. Then, the device driver runs in a release mode to initialize the hardware device with the initialization parameter previously stored. Therefore, the time for calibrating hardware device repeatedly is reduced significantly.
Claims20
A device driver initialization process for initializing a hardware device of a processor system, comprising:
- running the device driver in a learning mode, so as to read and store an initialization parameter of the hardware device that has been initialized;
- and
- switching the device driver to a release mode, so as to initialize the hardware device with the initialization parameter.
A device driver initialization process for initializing a hardware device of a processor system, comprising:
- reading an initialization parameter that is needed by the hardware device, wherein the initialization parameter is obtained by reading and storing the initialized parameter of the hardware device;
- and
- initializing the hardware device by the device driver with the initialization parameter.
A device driver initialization parameter learning process for learning an initialization parameter of a hardware device of a processor system, comprising:
- reading the initialization parameter that has been initialized and is stored in a hardware device register;
- and
- storing the initialization parameter.
