|
|
|
|
|
|
|
|
|
|
## Introduction
|
|
|
|
|
|
|
|
|
|
The Intel(R) Graphics Compute Runtime for OpenCL(TM) is a open source project to
|
|
|
|
|
converge Intel's development efforts on OpenCL(TM) compute stacks supporting the
|
|
|
|
|
GEN graphics hardware architecture.
|
|
|
|
|
|
|
|
|
|
Please refer to http://01.org/compute-runtime for additional details regarding Intel's
|
|
|
|
|
motivation and intentions wrt OpenCL support in the open source.

## Known Issues and Limitations
|
|
|
|
|
|
|
|
|
|
OpenCL compliance of a driver built from open-source components should not be
|
|
|
|
|
assumed by default. Intel will clearly designate / tag specific builds to
|
|
|
|
|
indicate production quality including formal compliance. Other builds should be
|
|
|
|
|
considered experimental.
|

|
|
|
The driver requires Khronos ICD loader to operate correctly:

|
|
|
|
|
|

|
|
|
The driver has the following functional delta compared to previously released drivers:
|
|
|
|
|
* Intel's closed source SRB5.0 driver (aka Classic)
|
|
|
|
|
https://software.intel.com/en-us/articles/opencl-drivers#latest_linux_driver
|
|
|
|
|
* Intel's former open-source Beignet driver
