Description jzhper 2012-02-06 05:07:41 UTC

/usr/portage/profiles/base/use.mask and /usr/portage/profiles/hardened/linux/use.mask masked the "opencl" USE flag on the basis that NVIDIA is the sole provider for OpenCL libraries. However that is not the case anymore. Intel, through dev-util/intel-ocl-sdk and AMD, through >=ati-drivers-12.1-r1, and through =ati-drivers-12.1 with the "opencl" USE flag, already includes with it the necessary libraries. Hence, "USE=opencl emerge -1 imagemagick -p" should have the "opencl" USE flag enabled as opposed to "(-opengl)". Therefore, I request that the "-opencl" mask be removed.

Reproducible: Always

Steps to Reproduce:
Run "USE=opencl emerge -1 imagemagick -p" on a recent Gentoo system with profile hardened/linux/amd64/no-multilib/selinux and with recent AMD Radeon GPU(s) and appropriate x11-drivers/ati-drivers.

Actual Results:  
Portage returns to us "(-opencl)" 

Expected Results:  
Portage returns to us "opencl" in USE.
