Chapter 4:

Software Platform

For more information about the common kernel mode drivers for Hardware Platforms 

targeting PCIe accelerator cards with XDMA IP, see the 

SDAccel Environment Platform 

Development Guide

 (UG1164) 

[Ref 2]

. 

IMPORTANT:

User modifications to the address map, DMA, or host interface of the provided platform 

could necessitate a new or modified kernel mode driver.

Hardware Abstraction Layer (HAL) Driver

The HAL driver is included with the SDx Environments installation and is required by the 

SDAccel runtime to communicate with the PCIe accelerator card. It is used for downloading 

FPGA bitstreams; allocating, deallocating, and migrating buffers; device profiling; and for 

communicating with the device and its kernels. The HAL driver is layered on top of the 

kernel mode drivers, and exposes C-style APIs to the runtime or other user of the driver.

The HAL driver is not specific to the Xilinx Acceleration KCU1500 4DDR Expanded Partial 

Configuration platform. For more information about the common HAL driver for Hardware 

Platforms that utilize the kernel mode drivers, see the 

SDAccel Environment Platform 

Development Guide

 (UG1164) 

[Ref 2]

. 

IMPORTANT:

User modifications to the kernel mode drivers or replacement of a kernel mode driver 

could necessitate a new or modified HAL driver.
