Until all functionality is moved over to rdmavt drivers still need to access a number of fields in data structures that are predominantly meant to be used by rdmavt. Once these rdmavt_<ibta_object>.h header files are no longer being touched by drivers their content should be moved to rdmavt/<ibta_object>.h. While here move a couple #defines over to more general IB verbs header files because they fit better. Reviewed-by:

Converge the ibport data structures of qib and hfi1 into a common ib port structure. Also provides a place to keep track of these ports in case rdmavt needs it. Along with this goes an attach and detach function for drivers to use to notify rdmavt of the ports. Reviewed-by:

Patch moves the srq data structure into rdmavt in preparation for removal from qib and hfi1 which will follow in subsequent patches. Reviewed-by:

Original patch is from Kamal Heib <kamalh@mellanox.com>. It has been split into three separate patches. This one for rdmavt, a follow on for qib, and one for hfi1. Create datastructure for address handle and implement the create/destroy/modify/query of address handle for rdmavt. Reviewed-by:

Trying to print debug and error messages with the rdmavt helpers will not work out so well if the drivers have not provided the get_card and get pci functions. Use the normal pr_error instead until we can check this. Reviewed-by:

Use the memory registration routines in hfi1 and move them to rdmavt. A follow on patch will address removing the duplicated code in the hfi1 and qib drivers. Reviewed-by:

Drivers will need a set of flags to dictate behavior to rdmavt. This patch adds a placeholder and a spot for it to live, as well as a few flags that will be used. Reviewed-by:

Follow hfi1's example for printing information about the driver and incorporate into rdmavt. This requires two new functions to be provided by the driver, one to get_card_name and one to get_pci_dev. Reviewed-by:

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. Reviewed-by:

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:

The handler for query gid operates along the same lines as the query pkey handler. The driver will take care to keep the guid table updated. Reviewed-by:

Dennis Dalessandro authored
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. Reviewed-by:

Dennis Dalessandro authored
This patch adds the query and modify port stubs. The query will mostly entail the driver returning everything in the ib_port_attr which will get handed back to the verbs layer. The modify will need some API helpers in the driver. The send_trap and post_mad_send are still issues to address. Reviewed-by:

Adds the stubs which will handle the query and modify device functions. At this time the only intention is to support changing the node desc and the guid via these calls. Reviewed-by:

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. Reviewed-by:

This patch adds dma functions to rdmavt. The source is hfi1's version of dma.c which will be removed by a subsequent hfi1 patch. Reviewed-by:

Dennis Dalessandro authored
This patch introduces the basics for a new module called rdma_vt. This new driver is a software implementation of the InfiniBand verbs and aims to replace the multiple implementations that exist and duplicate each others' code. While the call to actually register the device with the IB core happens in rdma_vt, most of the work is still done in the drivers themselves. This will be changing in a follow on patch this is just laying the groundwork for this infrastructure. Reviewed-by:

The link state will transition from ARMED to ACTIVE when a non-SC15 packet arrives, but the driver might not notice the change. With this fix, if the slowpath receive interrupt handler sees a non-SC15 packet while in the ARMED state, we queue work to call linkstate_active_work from process context to promote it to ACTIVE.
