How to make get_mempolicy return a node id list for an address range?
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
Hi, Given a range of virtual addresses (begin and end) which are allocated using MPOL_INTERLEAVE, is there a quick way to know how this range is mapped to different NUMA nodes? In particular, I would like to have a weighted node-id list, where each node id in the list indicates how many address (or pages) are mapped to it, similar to what is seen in /proc/<proc_id>/numa_maps. I am thinking of doing this by using get_mempolicy(MPOL_F_NODE|MPOL_F_ADDR) for every address in the range. This can be optimized for full correctness if I know the starting address of all pages contained in the range. Can you give me some tips on how to obtain that? Thank you!
