Driver Sources
The source code for the driver is included with the Vitis Unified Software Platform installation, as well as being available in the Xilinx Github repository.
Driver Name | Path in Vitis | Path in Github |
|---|---|---|
| scugic | <Vitis Install Directory>/data/embedded/XilinxProcessorIPLib/drivers/scugic | https://github.com/Xilinx/embeddedsw/tree/master/XilinxProcessorIPLib/drivers/scugic |
| Info |
|---|
Note: To view the sources for a particular release, use the rel-version tag in github. For example, for the 2020.1 release, the proper version of the code is: https://github.com/Xilinx/embeddedsw/tree/release-2020.1/XilinxProcessorIPLib/drivers/scugic |
The driver source code is organized into different folders. The table below shows the ospipsv driver source organization.
Directory | Description |
|---|---|
doc | Provides the API and data structure details |
data | Driver .tcl, .mdd and .mdd yaml file |
examples | Example applications that show how to use the driver features |
| src | Driver source files, make and cmakelists file |
Note: The .yaml(in data folder) and CMakeLists.txt(in src folder) files would be used in System Device Tree based flow.
Driver Implementation
For a full list of features supported by this IP, please refer ARM GIC v2 and v3 specifications.
