H A D | contiguous.c | bf29bfaa Wed Jul 12 02:47:58 CDT 2023 Yajun Deng <yajun.deng@linux.dev> dma-contiguous: support numa CMA for specified node
The kernel parameter 'cma_pernuma=' only supports reserving the same size of CMA area for each node. We need to reserve different sizes of CMA area for specified nodes if these devices belong to different nodes.
Adding another kernel parameter 'numa_cma=' to reserve CMA area for the specified node. If we want to use one of these parameters, we need to enable DMA_NUMA_CMA.
At the same time, print the node id in cma_declare_contiguous_nid() if CONFIG_NUMA is enabled.
