•  A common HAL provides the necessary abstraction to all the CCSP components to interface with other common hardware components.
•  Components may define a component specific HAL to hardware drivers, that are only used by that component

Component Specific HAL

• HAL APIs will be available in the CMF repo path: "../rdkb/components/opensource/ccsp/hal/source/"
• PandM HAL Integration (back-end) Layer is also known as component specific HAL.
• This layer makes call to underlying Linux system calls/commands, third party modules, open source modules and other CCSP components to execute the requests.
• This layer will be more component specific and will be providing APIs to CCSP so as to manage a particular hardware module of the system.
• Following HALs available in "../rdkb/components/opensource/ccsp/hal/source/" path.

Wi-Fi HAL Implementation

       All HAL functions prototypes and structure definitions are available in wifi_hal.h file.

• Latest version of RDKB supports 300+ Wi-Fi HAL API’s

• Based on how Wi-Fi vendor exposes their driver capabilities in user space, the HAL API’s can be implemented in wifi_hal.c

• To see the Wi-Fi HAL APIs. Please refer WiFiHAL in the component page.
