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

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

RDMA/cma: Allow user to restrict listens to bound address family

2012-07-09T01:02:24Z

Provide an option for the user to specify that listens should only accept connections where the incoming address family matches that of the locally bound address. This is used to support the equivalent of IPV6_V6ONLY socket option, which allows an app to only accept connection requests directed to IPv6 addresses.
