9.3.1. The Global Programmers View

The HPS-to-FPGA bridge includes a set of registers called the GPV. The GPV provides settings to control the bridge properties and behavior. Access to the GPV registers of all three bridges is provided through the lightweight HPS-to-FPGA bridge.

The GPV registers can only be accessed by secure masters in the HPS or the FPGA fabric.
