Summary: This is the big patch that implements an efficient device-side `malloc` on the GPU. This is the first pass and many improvements will be made later. The scheme revolves around using a global reference counted pointer to hand out access to a dynamically created and destroyed slab interface. The slab is simply a large bitfield with one bit for each slab. All allocations are the same size in a slab, so different sized allocations are done through different slabs. Allocation is thus searching for or creating a slab for the desired slab, reserving space, and then searching for a free bit. Freeing is clearing the bit and then releasing the space. This interface allows memory to dynamically grow and shrink. Future patches will have different modes to allow fast first-time-use as well as a non-RPC version.
