Method for creation of device drivers and device objects for peripheral devices
All steps required to create and operate a peripheral device of an electronic device can be performed without the need to plug in the peripheral device to the electronic device. Setup information for a peripheral device is extracted, modified and stored to fit to a physical existent peripheral device. The modified setup information is used to create a data structure that is passed to the peripheral bus driver. As the data structure contains a hot plug notification the reception causes the peripheral bus driver to initiate the setup process for the peripheral device. As the data structure is built from setup information that is available at the electronic device no additional user action is required. The invention also allows the creation of a device object for existing signed driver packets that may not be altered.
1. A method, comprising:
creating, via an electronic device, a setup information file and a temporary data structure to configure a driver of a peripheral device;
replacing, via the electronic device, pre-existing device identification (ID) information with a newly created peripheral device ID and storing the new peripheral device ID in the temporary data structure;
creating, via the electronic device, a request message based on the temporary data structure, the request message comprising a request to add a new device;
determining, via the electronic device, a new device is operating on a peripheral bus as a Plug and Play device; and
adding, via the electronic device, entries to provide Plug and Play functionality generated from the setup information file prior to plugging the peripheral device into the peripheral bus in communication with an electronic device.
2. The method of claim 1 , wherein a previously existent setup information is stored in the setup information file.
3. The method of claim 1 , wherein existent setup information is stored in a configuration memory of the electronic device.
4. The method of claim 1 , further comprising storing, via the electronic device, the new peripheral device ID of the peripheral device.
5. The method of claim 1 , further comprising passing, via the electronic device, an instance ID to the driver of the peripheral interface or bus to identify an instance of the peripheral device.
6. The method according to claim 1 , wherein the bus is an expansion bus.
7. The method according to claim 1 , wherein the bus is a peripheral bus.
8. The method of claim 1 , wherein the peripheral device supports the functionality of multiple devices and the operations of creation of setup information, initialization and performance of an installation are performed for each supported functionality of the multiple devices.
9. An apparatus, comprising:
a memory; and
a processor communicably coupled to the memory, the processor configured to:
create a setup information file and a temporary data structure to configure a driver of a peripheral device;
replace pre-existing device identification (ID) information in a newly created peripheral device ID and store the new peripheral device ID in the temporary data structure;
create a request message based on the temporary data structure, the request message comprising a request to add a new device
determine a new device is operating on a peripheral bus as a Plug and Play device; and
add entries to provide Plug and Play functionality generated from the setup information file prior to the peripheral device being plugged into the peripheral bus in communication with the electronic device.
10. The apparatus of claim 9 , wherein a previously existent setup information is stored in the setup information file.
11. The apparatus of claim 9 , wherein existent setup information is stored in a configuration memory of the apparatus.
12. The apparatus of claim 9 , wherein the processor is further configured to pass an instance ID to the driver of the peripheral interface to identify an instance of the peripheral device.
13. The apparatus of claim 9 , wherein the processor is further configured to pass an instance ID to the driver of the bus to identify an instance of the peripheral device.
14. The apparatus of claim 9 , wherein the bus is an expansion bus.
15. The apparatus of claim 9 , wherein the bus is a peripheral bus.
16. The apparatus of claim 9 , wherein the peripheral device supports the functionality of multiple devices and the operations of creation of setup information, initialization and performance of an installation are performed for each supported functionality of the multiple devices.
17. A non-transitory computer readable medium comprising a computer program that when executed causes a processor to perform:
creating a setup information file and a temporary data structure to configure a driver of a peripheral device;
replacing pre-existing device identification (ID) information with a newly created peripheral device ID and storing the new peripheral device ID in the temporary data structure;
creating a request message based on the temporary data structure, the request message comprising a request to add a new device;
determining a new device is operating on a peripheral bus as a Plug and Play device; and
adding entries to provide Plug and Play functionality generated from the setup information file prior to plugging the peripheral device into the peripheral bus in communication with an electronic device.
18. The method of claim 1 , further comprising creating a device object of the electronic device and binding the device object to the peripheral device to provide a signed driver that is used during the installation of the peripheral device.
19. The apparatus of claim 9 , wherein the processor is further configured to create a device object of the apparatus and bind the device object to the peripheral device to provide a signed driver that is used during the installation of the peripheral device.
20. The non-transitory computer readable medium of claim 17 , wherein the processor is further configured to perform creating a device object of the electronic device and binding the device object to the peripheral device to provide a signed driver that is used during the installation of the peripheral device.
