Bug 490372 – media-libs/mesa[opencl] should not manipulate VIDEO_CARDS in sys-devel/llvm

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Manuel Rüger (RETIRED) 2013-11-04 12:47:19 UTC]

The following keyword changes are necessary to proceed:
 (see "package.accept_keywords" in the portage(5) man page for more details)
# required by media-libs/mesa-9.2.2[opencl]
# required by mesa (argument)
=dev-libs/libclc-0.0.1_pre20130819-r1 ~amd64

The following USE changes are necessary to proceed:
 (see "package.use" in the portage(5) man page for more details)
# required by media-libs/mesa-9.2.2[opencl]
# required by mesa (argument)
=sys-devel/llvm-3.3-r1 video_cards_radeon
# required by media-libs/mesa-9.2.2[opencl]
# required by mesa (argument)
=sys-devel/clang-3.3-r100 abi_x86_32


Adding video_cards_radeon is useless on a system which has no radeon-card. 

Maybe rename this useflag to opencl_radeon?

There is also another opencl implementation from intel, which we could add to the tree:
dev-libs/intel-beignet

opencl? (
              >=sys-devel/llvm-3.3-r1[video_cards_radeon,${MULTILIB_USEDEP}]
              >=sys-devel/clang-3.3[${MULTILIB_USEDEP}]
              >=sys-devel/gcc-4.6
)

Yeah, doesn't nouveau have OpenCL? I think requiring video_cards_radeon isn't what we want here.

I think that is a leftover from when radeon was the only OpenCL implementation in mesa.

same issue here since the xorg stabilization went through, so I'm running mesa -opencl for now...

I see

    opencl? (
        gallium
        llvm
        video_cards_r600? ( r600-llvm-compiler )
        video_cards_radeon? ( r600-llvm-compiler )
        video_cards_radeonsi? ( r600-llvm-compiler )
    )

in current Mesa. I think this is fixed.
