Add new ioctl method for the MR object - ADVISE_MR. This command can be used by users to give an advice or directions to the kernel about an address range that belongs to memory regions. A new ib_device callback, advise_mr(), is introduced here to suupport the new command. This command takes the following arguments: - pd: The protection domain to which all memory regions belong - advice: The type of the advice * IB_UVERBS_ADVISE_MR_ADVICE_PREFETCH - Pre-fetch a range of an on-demand paging MR * IB_UVERBS_ADVISE_MR_ADVICE_PREFETCH_WRITE - Pre-fetch a range of an on-demand paging MR with write intention - flags: The properties of the advice * IB_UVERBS_ADVISE_MR_FLAG_FLUSH - Operation must end before return to the caller - sg_list: The list of memory ranges - num_sge: The number of memory ranges in the list - attrs: More attributes to be parsed by the provider Signed-off-by: Moni Shoua <monis@mellanox.com> Reviewed-by: Guy Levi <guyle@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com> |
