This commit introduces verbs for creating/destoying memory regions which will allow new types of memory key operations such as protected memory registration. Indirect memory registration is registering several (one of more) pre-registered memory regions in a specific layout. The Indirect region may potentialy describe several regions and some repitition format between them. Protected Memory registration is registering a memory region with various data integrity attributes which will describe protection schemes that will be handled by the HCA in an offloaded manner. These memory regions will be applicable for a new REG_SIG_MR work request introduced later in this patchset. In the future these routines may replace or implement current memory regions creation routines existing today: - ib_reg_user_mr - ib_alloc_fast_reg_mr - ib_get_dma_mr - ib_dereg_mr Signed-off-by: Sagi Grimberg <sagig@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
