Contributing to ROCR
|
||
========================
|
||
|
||
This document contains useful information required to contribute to ROCR.

Runtime design
|
||
-----------------
|
||
|
||
ROCR consists of the following primary layers:
|
||
|
||
1. :ref:`C interface adaptors <c-interface-adaptors>`
|
||
|
||
2. C++ interface classes and common functions
|
||
|
||
3. Device-specific implementations
|
||
|
||
The first layer provides interfaces to make ROCR APIs available to the user applications.
|
||
The second and third layers comprise of the internal ROCR implementation, which is available for contribution.
|
||
|
||
Additionally, the runtime is dependent on a small utility library that provides simple common functions, limited operating system, compiler abstraction, and atomic operation interfaces.
|
||
|
||
The following sections list the important files present in the second and third layer.
|
||
|
||
C++ interface classes and common functions
|
||
----------------------------------------------
|
||
|
||
The C++ interface layer provides abstract interface classes encapsulating commands to HSA signals, agents, and queues. This layer also contains the implementation of device-independent commands, such as ``hsa_init``, ``hsa_system_get_info``, and a default signal and queue implementation.
|
||
|
||
Files present in this layer:
|
||
|
||
- ``runtime.h`` (cpp)
|
||
|
||
- ``agent.h``
|
||
|
||
- ``queue.h``
|
||
|
||
- ``signal.h``
|
||
|
||
- ``memory_region.h`` (cpp)
|
||
|
||
- ``checked.h``
|
||
|
||
- ``memory_database.h`` (cpp)
|
||
|
||
- ``default_signal.h`` (cpp)
|
||
|
||
Device-specific implementations
|
||
----------------------------------
|
||
|
||
The device-specific layer contains implementations of the C++ interface classes that implement HSA functionality for ROCm supported devices.
|
||
|
||
Files present in this layer:
|
||
|
||
- ``amd_cpu_agent.h`` (cpp)
|
||
|
||
- ``amd_gpu_agent.h`` (cpp)
|
||
|
||
- ``amd_hw_aql_command_processor.h`` (cpp)
|
||
|
||
- ``amd_memory_region.h`` (cpp)
|
||
|
||
- ``amd_memory_registration.h`` (cpp)
|
||
|
||
- ``amd_topology.h`` (cpp)
|
||
|
||
- ``host_queue.h`` (cpp)
|
||
|
||
- ``interrupt_signal.h`` (cpp)
|
||
|
||
- ``hsa_ext_private_amd.h`` (cpp)
|
||
|
||
