# CONFIG_ZSMALLOC_PGTABLE_MAPPING: # # By default, zsmalloc uses a copy-based object mapping method to # access allocations that span two pages. However, if a particular # architecture (ex, ARM) performs VM mapping faster than copying, # then you should select this. This causes zsmalloc to use page table # mapping rather than copying for object mapping. # # You can check speed with zsmalloc benchmark: # https://github.com/spartacus06/zsmapbench # # Symbol: ZSMALLOC_PGTABLE_MAPPING [=n] # Type : bool # Defined at mm/Kconfig:708 # Prompt: Use page table mapping to access object in zsmalloc # Depends on: ZSMALLOC [=y]=y # Location: # -> Memory Management options # -> Memory allocator for compressed pages (ZSMALLOC [=y]) # # # # CONFIG_ZSMALLOC_PGTABLE_MAPPING is not set
