Populating pointers of struct from cupy #211

Description

@neworderofjamie

Not really an issue but, I'm trying to populate a struct in constant memory containing (device) pointers in order to run my kernel through kernel tuner. In C the struct looks something like:

struct MergedNeuronUpdateGroup0
 {
    unsigned int* spkCnt;
    unsigned int* spk;
};
__device__ __constant__ MergedNeuronUpdateGroup0 d_mergedNeuronUpdateGroup0[8];

I can see how I would pack pointers into this with struct.pack("PP0l", spk_cnt, spk) and then convert to numpy as described in your example before passing via the cmem_args kwarg to tune_kernel. But, I've no idea how I would create (and initialise) these pointers from Python! Any pointers?

Thanks in advance for your help!
