IB/core: Add "type 2" memory windows support

2013-02-21T19:51:45Z

This patch enhances the IB core support for Memory Windows (MWs). MWs allow an application to have better/flexible control over remote access to memory. Two types of MWs are supported, with the second type having two flavors: Type 1 - associated with PD only Type 2A - associated with QPN only Type 2B - associated with PD and QPN Applications can allocate a MW once, and then repeatedly bind the MW to different ranges in MRs that are associated to the same PD. Type 1 windows are bound through a verb, while type 2 windows are bound by posting a work request. The 32-bit memory key is composed of a 24-bit index and an 8-bit key. The key is changed with each bind, thus allowing more control over the peer's use of the memory key. The changes introduced are the following: * add memory window type enum and a corresponding parameter to ib_alloc_mw. * type 2 memory window bind work request support. * create a struct that contains the common part of the bind verb struct ibv_mw_bind and the bind work request into a single struct. * add the ib_inc_rkey helper function to advance the tag part of an rkey. Consumer interface details: * new device capability flags IB_DEVICE_MEM_WINDOW_TYPE_2A and IB_DEVICE_MEM_WINDOW_TYPE_2B are added to indicate device support for these features. Devices can set either IB_DEVICE_MEM_WINDOW_TYPE_2A or IB_DEVICE_MEM_WINDOW_TYPE_2B if it supports type 2A or type 2B memory windows. It can set neither to indicate it doesn't support type 2 windows at all. * modify existing provides and consumers code to the new param of ib_alloc_mw and the ib_mw_bind_info structure Signed-off-by: Haggai Eran Signed-off-by: Shani Michaeli Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

IB/core: Add ib_find_exact_cached_pkey()

2012-10-01T03:33:30Z

When P_Key tables potentially contain both full and partial membership copies for the same P_Key, we need a function to find the index for an exact (16-bit) P_Key. This is necessary when the master forwards QP1 MADs sent by guests. If the guest has sent the MAD with a limited membership P_Key, we need to to forward the MAD using the same limited membership P_Key. Since the master may have both the limited and the full member P_Keys in its table, we must make sure to retrieve the limited membership P_Key in this case.

IB/core: Reserve bits in enum ib_qp_create_flags for low-level driver use

2012-10-01T03:33:28Z

Reserve bits 26-31 for internal use by low-level drivers. Two such bits are used in the mlx4_b driver SR-IOV implementation. These enum additions guarantee that the core layer will never use these bits, so that low level drivers may safely make use of them. Signed-off-by: Jack Morgenstein Signed-off-by: Roland Dreier

IB/core: Move CM_xxx_ATTR_ID macros from cm_msgs.h to ib_cm.h

2012-07-09T01:05:06Z

These macros will be reused by the mlx4 SRIOV-IB CM paravirtualization code, and there is no reason to have them declared both in the IB core in the mlx4 IB driver. Signed-off-by: Jack Morgenstein Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier
