* IB/hfi1: Add the capability for reserved operationsMike Marciniszyn2016-08-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | This fix allows for support of in-kernel reserved operations without impacting the ULP user. The low level driver can register a non-zero value which will be transparently added to the send queue size and hidden from the ULP in every respect. ULP post sends will never see a full queue due to a reserved post send and reserved operations will never exceed that registered value. The s_avail will continue to track the ULP swqe availability and the difference between the reserved value and the reserved in use will track reserved availabity.

* IB/rdmavt: Add mechanism to invalidate MR keysJianxin Xiong2016-08-021-0/+3
| | | | | | | | | | | | | | In order to support extended memory management, add the mechanism to invalidate MR keys. This includes a flag "lkey_invalid" in the MR data structure that is to be checked when validating access to the MR via the associated key, and two utility functions to perform fast memory registration and memory key invalidate operations.

* IB/rdamvt: Fix rdmavt s_ack_queue sizingMike Marciniszyn2016-05-261-0/+9
| | | | | | | | | | | | | | | | rdmavt allows the driver to specify the size of the ack queue, but only uses it for the modify QP limit testing for setting the atomic limit value. The driver dependent size is now used to size the s_ack_queue ring dynamicially. Since the driver knows its size, the driver will use its define for any ring size dependent code.

* IB/rdmavt: Move driver helper functions to a common structureDennis Dalessandro2016-03-101-7/+15
| | | | | | | | | | | Drivers are going to need to provide multiple functions for rdmavt to call in to. We already have one, so go ahead and push this into a data structure designated for driver supplied functions.

| | | | | | | | | | | | | This patch adds the MR datastructures based on hfi1 into rvt. For now the data structures are defined in include/rdma/rdma_vt.h but once all MR functionality has been moved from the drivers into rvt these should move to rdmavt/mr.h Reviewed-by: Ira Weiny <ira.weiny@intel.com> Reviewed-by: Dean Luick <dean.luick@intel.com> Reviewed-by: Mike Marciniszyn <mike.marciniszyn@intel.com> Signed-off-by: Dennis Dalessandro <dennis.dalessandro@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>

| | | | | | | | | | | The pkey table will reside in the rvt structure but it will be modified only when the driver requests then rvt will simply read the value to return in the query.

| | | | | | | | | | | Instead of trying to handle each parameter separately, add ib_device_attr to rvt_driver_params. This means drivers will fill this in and pass to the rvt registration function.
