    SLC write in OpenCL?

    nerdralph

      Is there any way to do a SLC write in OpenCL, or force a L2 cache line flush after a write?  I'm doing writes that I know won't be read back for a long time, so I don't want them polluting the L2.

      I've tried volatile pointers and write_mem_fence, both of which just add

      s_waitcnt vmcnt(0)

      after the writes.
