[Mesa-dev] OpenCL for radeon Hawaii?

[Ilia Mirkin]

Without commenting on the opencl question(which should be supported, but
perhaps not a late enough spec version that your programs require), you
should be able to get all the necessary functionality by writing opengl
compute programs, supported in both desktop core and es profiles.
