On architectures like ppc64 we # can map the memmap area using 16MB hugepage size and that can cover # a memory range of 16G. # # While enabling new pmem namespaces, since memory is added in sub-section chunks, # before creating a new memmap mapping, kernel should check whether there is an # existing memmap mapping covering the new pmem namespace. Currently, this is # validated by checking whether the section covering the range is already # initialized or not. Considering there can be multiple namespaces in the same # section this can result in wrong validation. Update this to check for # sub-sections in the range. This is done by checking for all pfns in the range we # are mapping. # # We could optimize this by checking only just one pfn in each sub-section. But # since this is not fast-path we keep this simple. # # Signed-off-by: Aneesh Kumar K.V # Signed-off-by: Michael Ellerman # Link:
