Overview of CHIP Linux Adaption

The following is a quick overview of the Linux adaptation of CHIP. Most of this code will have parallels in any new adaptation.

(All file names are relative to connectedhomeip/src/...).

include/platform/Linux/PlatformManagerImpl.h Linux/PlatformManagerImpl.cpp

• Concrete implementation of PlatformManager interface
• Provides initialization of the CHIP stack and core event loop for the chip task
• Relies on GenericPlatformManagerImpl_POSIX<> class to provide most of the implementation

include/platform/Linux/ConfigurationManagerImpl.h Linux/ConfigurationManagerImpl.cpp

• Concrete implementation of ConfigurationManager interface
• Manages storage and retrieval of persistent configuration data
• Relies on GenericConfigurationManagerImpl<> classes to implement most API functionality
• Delegates low-level reading and writing of persistent values to PosixConfig class

include/platform/Linux/ConnectivityManagerImpl.h Linux/ConnectivityManagerImpl.cpp

• Concrete implementation of ConnectivityManager interface
• Provides high-level APIs for managing device connectivity
• Relies on various generic implementation classes to provide API functionality
• Very much a work-in-progress in the Linux branch

include/platform/Linux/ThreadStackManagerImpl.h Linux/ThreadStackManagerImpl.cpp

• Concrete implementation of ThreadStackManager interface
• Supports Thread stack initialization and core event loop processing
• Relies on GenericThreadStackManagerImpl_OpenThread/POSIX<> classes to implement most API functionality

include/platform/Linux/BLEManagerImpl.h Linux/BLEManagerImpl.cpp

• Concrete implementation of the BLEManager interface
• Maps CHIP's BLE interface abstractions (BleLayer, BlePlatformDelegate, BleApplicationDelegate) onto the platform's native BLE services
• Implements chip-compatible BLE advertising.

platform/Linux/Entropy.cpp

• Implements interface to platform entropy source

platform/Linux/Logging.cpp

• Adaption of chip debug logging to platform logging facility.

platform/Linux/PosixConfig.cpp

• Implements low-level read/write of persistent configuration values
• Class API specifically designed to work in conjunction with the GenericConfigurationManagerImpl<> class.
