From 17cd3a2db825506c3e3bb9548ad20f67e2f8d0e7 Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Sun, 23 Feb 2014 14:19:04 +0200 Subject: [PATCH] IB/core: Introduce protected memory regions 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 Signed-off-by: Roland Dreier --- Reading git-format-patch failed
