The Hardware Driver Foundation (HDF) provides the following driver framework capabilities: driver loading, driver service management, and driver message mechanism. This unified driver architecture platform is designed to provide a more precise and efficient development environment, where you can perform one-time development and multi-system deployment.
Both on-demand loading and sequential loading are supported.
On-demand loading
Drivers can be loaded by default during the operating system (OS) startup or be loaded dynamically after the OS startup.
Sequential loading
Drivers can be loaded based on their priorities during the OS startup.
The HDF centrally manages driver services. You can directly obtain a specified driver service by using the API provided by the HDF.
The HDF provides a unified driver message mechanism, which allows message interactions between user-level applications and kernel-level drivers.
