5.5 Platform Abstraction and Native OS Abstraction
The platform abstraction and native OS abstraction provides abstraction to the platform
features and operating system interfaces. This component provides isolation to the other
components of the device stack architecture from platform and native operating system and
allows portability of the device stack components.
5.6 Device Stack Component Libraries and Dependencies
Table 3 lists the device stack components and the corresponding libraries included in the
PSP deliverable.
Table 3: USB Device Stack Component Libraries and Dependency
5.7 Device Stack Component Build Options
Multiple build options can be specified for compilation of the USB device stack components.
Table 4 lists the build options that have been used to build the device stack components
that are available in the BIOS USB product.
