# CONFIG_DMA_PERNUMA_CMA: # # Enable this option to get pernuma CMA areas so that devices like # ARM64 SMMU can get local memory by DMA coherent APIs. # # You can set the size of pernuma CMA by specifying "cma_pernuma=size" # on the kernel's command line. # # Symbol: DMA_PERNUMA_CMA [=n] # Type : bool # Defined at kernel/dma/Kconfig:126 # Prompt: Enable separate DMA Contiguous Memory Area for each NUMA Node # Depends on: DMA_CMA [=y] # Location: # -> Library routines # -> DMA Contiguous Memory Allocator (DMA_CMA [=y]) # # # # CONFIG_DMA_PERNUMA_CMA is not set
