When using implicit scaling, device allocations may have more than one internal allocation created internally. In that case, a separate dma-buf handle per internal allocation needs to be exported. So introduced two driver experimental extensions to export and import more than one IPC handle: - zexMemGetIpcHandles - zexMemOpenIpcHandles Related-To: LOCI-2919 Signed-off-by: Jaime Arteaga <jaime.a.arteaga.molina@intel.com>
