Method and apparatus for prefetching peripheral device drivers for smart phones and other connected devices prior to HLOS boot

摘要

Apparatus and methods for booting a user equipment are described. A device boot of the user equipment may be performed. Peripherals and associated drivers for the user equipment may be configured. A high-level operating system (HLOS) may be booted. The configuring may occur before the booting of the HLOS. Apparatus and methods for loading peripheral device drivers for a user equipment are also described. Peripherals that can be associated with a user equipment may be determined. Drivers for the determined peripherals may be loaded. The loaded drivers may be associated with a high-level operating system (HLOS) architecture regardless of a type of user equipment on which the HLOS is provided.

1. A method for booting a user equipment, comprising:
performing a device boot of the user equipment; determining whether profiles for peripherals associated with the user equipment are available at the user equipment; upon determining that a profile for one of the peripherals is not available at the user equipment but is available at a location external to the user equipment, the location being managed by a manufacturer associated with the one of the peripherals, retrieving the profile for the one of the peripherals from the location; configuring the peripherals and associated drivers for the user equipment by at least updating the profile for the one of the peripherals based on the retrieved profile; and booting a high-level operating system (HLOS), wherein the configuring makes information related to at least one driver associated with each of the peripherals available to the HLOS, and the configuring occurs before the booting of the HLOS.
