Driver NEO OpenCL from Intel updated to version 19.20.13008. It provides OpenCL 2.1 support for Intel GPUs starting with Broadwell. Those with a Haswell or older GPU are encouraged to use the Beignet driver, which is Legacy.
Among the changes: Intel Graphic Compiler has been updated to the latest version 1.0.4.
Installation manual, assembly instructions in 7 CentOS. Release Notes: Fine grained SVM not supported in this release. If you have Ubuntu 16.04.4 and the default kernel 4.13, then for CFL platforms you need to add the kernel parameter i915.alpha_support=1
In March, thanks Intel open source drivers, it became known about the new SoC Intel Elkhart Lake. Now, thanks to them, стало известно codename PCH, which will be used in them - Mule Creek Canyon.
Vulkan has been released 1.1.109, which includes two new extensions from Intel:
- VK_INTEL_performance_query - This extension allows an application to capture performance data for additional library/application specific analytics. This extension will be used by Intel Graphics Performance Analyzers and Intel Metrics Discovery library. This extension may also be useful for third-party analysis/profiling utilities
- VK_INTEL_shader_integer_functions2 - This extension adds new integer instructions to SPIR-V, similar to the GLSL extension for OpenGL INTEL_shader_integer_functions2
In the Intel "Iris" Gallium3D driver for Linux appeared Shader disk cache support. Previously, this feature was present in the Classic Mesa driver for Linux. Support should be expected in Mesa 19.2.
Finally, Intel works on the use of high-performance eLLC/eDRAM memory for write-back caching of display buffers. This will work on Skylake and newer, but not on older chips that also have eDRAM.
