Avoid L1 cache pollution on GCN

I have a kernel that writes results to a global buffer; these results are never read back into the kernel (they are processed by another kernel at a later time).

So, I don't want this data sitting in the L1 cache if I can help it. Is there a way of ensuring that it is not cached?

I need L1 for another array that is frequently read from and written to. This array is around 1kb per work item, so it should stay in the L1 cache.

Thanks.

Re: Avoid L1 cache pollution on GCN

I have the same problem and also want to know the answer. Using GCN assembly is fine for me.
