One, instead of pulling in various OpenCL runtimes, only depend on |
| 2 |
an OpenCL ICD loader (dev-libs/ocl-icd, with dev-libs/opencl-icd-loader |
| 3 |
to be added later) in order to provide hardware-independent header |
| 4 |
files and libraries for OpenCL-aware software to build against. |
| 5 |
Actual runtimes are now simply suggested to the user via a postinst |
| 6 |
message / README.gentoo file. |

Two, do not depend on eselect-opencl either - both ICD loaders pull in |
| 9 |
their own OpenCL headers so there is no need to depend on the legacy |
| 10 |
headers provided by this package, and for being able to switch to a |
| 11 |
specific loader it is enough for loaders themselves to depend on this. |

+In order to take advantage of OpenCL you will need a runtime for your hardware. |
| 28 |
+Currently included in Gentoo are: |
| 29 |
+ |
| 30 |
+ * open: |
| 31 |
+ - dev-libs/intel-neo - integrated Intel GPUs from Broadwell onwards. 64-bit only; |
| 32 |
+ - dev-libs/rocm-opencl-runtime - AMD GPUs supported by the amdgpu kernel driver. |
| 33 |
+ Image support still requires a proprietary extension [1]. 64-bit only; |
| 34 |
+ - media-libs/mesa[opencl] - some older AMD GPUs; see [2]. 32-bit support; |
| 35 |
+ |
| 36 |
+ * proprietary: |
| 37 |
+ - dev-libs/amdgpu-pro-opencl - AMD Polaris GPUs. 32-bit support; |
| 38 |
+ - dev-util/intel-ocl-sdk - Intel CPUs (*not* GPUs). 64-bit only; |
| 39 |
+ - x11-drivers/nvidia-drivers[uvm] - Nvidia GPUs; specific package versions |
| 40 |
+ required for older devices [3]. 32-bit support. |
