Subject: virtual/opencl: add VIDEO_CARDS=amdgpu support
X-Git-Url: http://git.tremily.us/gitweb.cgi?a=commitdiff_plain;h=5333f190c3388bf71552464fd59ab6dd80ea24a4;p=gentoo.git

virtual/opencl: add VIDEO_CARDS=amdgpu support

Radeon Open Compute has not been added to Gentoo yet but even without it, it is possible
to enable OpenCL on recent AMD cards by combining OpenCL libraries from the proprietary
AMDGPU-Pro stack with the Open Source amdgpu stack. It's a hack but it works, at least
on Polaris GPUs.

Package-Manager: Portage-2.3.6, Repoman-2.3.1
