Implementing HAL Operations

This section describes the work needed to implement a new HAL, which consists mainly of overriding functions in the refsi_hal_device class and adding an implementation for each ‘HAL operation’ defined by the HAL in hal_device_t. We will go through all of the operations which are required to run a kernel and periodically run different clik tests to show how implementation progress is reflected in test output.

• Device Initialization and Cleanup
• Allocating and Copying Device Memory
• Loading Programs on the Device
• Running Kernels
  • Executing a Simple Command Buffer
  • Loading and Executing Kernels Without Scheduling
  • Simple Kernel Scheduling
  • Kernel Argument Packing
  • 2D and 3D Kernel Scheduling
