[gentoo-user] MESA + opencl = requires video_cards_radeon

[gentoo-user] MESA + opencl = requires video_cards_radeon

[Chris Stankevitz]

Hello,

Regarding the following snip from
/usr/portage/media-libs/mesa/mesa-10.0.4.ebuild:

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

Does this say "if you want to use opencl then you have to say that you
are using a radeon graphics card, even if you are not using a radeon
graphics card":

Thank you,

Chris

Hi.
I know for sure that mesa doesn't fully support opencl for amd video
card (http://dri.freedesktop.org/wiki/GalliumCompute/). Since they
are not even cited, maybe it doesn't support opencl at all for
nvidia/intel. If you're gonna use gpgpu, I suggest you switch to the
proprietary drivers for the time being.
Btw, if you intend to try the intel sdk for opencl, it actually
computes on the cpu, not the integrated graphics.

Eric,

Thank you.  I will try to use beignet as I am using Intel hardware.
