@Steve Take a look at Xilinx's cores and drivers for reference. For example, the GPIO core at data ip xilinx axigpiov20 and driver data embeddedsw XilinxProcessorIPLib drivers gpiov44 data (directories are under your Xilinx install directory; version numbers might be different). – Justin N May 16 at 0:10.

Driver Information

Xilinx DriverThere are a number of drivers in the kernel tree due to history and they may work, but the following list of drivers are currently what's tested and users are encouraged to use these rather than others. Any other drivers, not in the mainline and only in the Xilinx tree, may be old and obsolete such that they could be removed at any time.

Xilinx QDMA Subsystem for PCIe example design is implemented on a Xilinx FPGA,which is connected to an X86 host system through PCI Express.Xilinx QDMA Linux Driver is implemented as a combination of user space andkernel driver components to control and configure the QDMA subsystem.

QDMA Linux Driver consists of the following four major components:

Xilinx Driver Code

  • QDMA HW Access: QDMA HW Access module handles all the QDMA IP register access functionality and exposes a set of APIs for register read/writes.

  • Libqdma: Libqdma module exposes a set of APIs for QDMA IP configuration and management. It uses the QDMA HW Access layer for interacting with the QDMA HW and facilitates the upper layers to achieve the following QDMA functionalities

    • Physical Function(PF) Management
    • Virtual Function(VF) Management
    • Communication Management between PF and VF
    • QDMA Queue Configuration and Control
    • Descriptor Rings Creation and Control
    • Transfer Management
    • DebugFS Support

  • Driver Interface: This layer create a simple linux pci_driver interface and a character driver interface to demonstrate the QDMA IP functionalities using the Linux QDMA IP driver. It creates a NL interface to facilitate the user applications to interact with the Libqdma module. It also creates sysfs interface to enable users to configure and control various QDMA IP parameters.

  • Applications: QDMA IP Driver provides the following sample applications.

    • Dmactl : This application provides set of commands to configure and control the queues in the system
    • dma_to_device : This application enables the users to perform Host to Card(H2C) transfer
    • dma_from_device : This application enables the users to perform Card to Host(C2H) transfer
    • Dmaperf : This application provides interfaces to extract performance numbers for QDMA IP in MM and ST modes
