in other words, no kernel support is required, and the hardware acts
as you'd expect (as a cache). if you happen to want it to restrict it
to only accelerating the onchip GPU, a kernel option is now available.
the topic was in using it for general HPC acceleration, not GPU, no?
it would be an interesting knob to have for openCL code...
