iWARP supports read with invalidate. There is an assumption that read with invalidate will only be called on an iWARP device Signed-off-by:

iWARP would require the chains to allocate/free their PBL memory independently, so add the infrastructure to provide it externally. Signed-off-by:

Add 64KB PAGE_SIZE support to user-space CQ, SQ and RQ queues. De-facto it means that code was added to translate 64KB pages to smaller 4KB pages that the FW can handle. Otherwise, the FW would wrap (or jump to the next page) when reaching 4KB while the user space library will continue on the same large page. Note that MR code remains as is since the FW supports larger pages for MRs. Signed-off-by:

rdma_ah_attr can now be either ib or roce allowing core components to use one type or the other and also to define attributes unique to a specific type. struct ib_ah is also initialized with the type when its first created. This ensures that calls such as modify_ah dont modify the type of the address handle attribute. Reviewed-by:

Modify core and driver components to use accessor functions introduced to access individual fields of rdma_ah_attr Reviewed-by:
-
Dasaratharaman Chandramouli authored
This patch simply renames struct ib_ah_attr to rdma_ah_attr as these fields specify attributes that are not necessarily specific to IB. Reviewed-by:

Size of pages are held by struct ib_umem in page_size field. It is better to store it as an exponent, because page size by nature is always power-of-two and used as a factor, divisor or ilog2's argument. The conversion of page_size to be page_shift allows to have portable code and avoid following error while compiling on ARM: ERROR: "__aeabi_uldivmod" [drivers/infiniband/core/ib_core.ko] undefined!

This patch advances the qed* drivers into using the newer firmware - This solves several firmware bugs, mostly related [but not limited to] various init/deinit issues in various offloaded protocols. It also introduces a major 4-Cached SGE change in firmware, which can be seen in the storage drivers' changes. In addition, this firmware is required for supporting the new QL41xxx series of adapters; While this patch doesn't add the actual support, the firmware contains the necessary initialization & firmware logic to operate such adapters [actual support would be added later on].

'qedr_alloc_pbl_tbl()' can not return NULL. In qedr_init_user_queue(): - simplify the test for the return value, no need to test for NULL - propagate the error pointer if needed, otherwise 0 (success) is returned. This is spurious. In init_mr_info(): - test the return value with IS_ERR - propagate the error pointer if needed instead of an exlictit -ENOMEM. This is a no-op as the only error pointer that we can have here is already -ENOMEM Signed-off-by:

Change the drivers to call ib_query_port in their get port immutable handler instead of their own query port handler. Doing this required to set the core cap flags of this device before the ib_query_port call is made, since the IB core might need these caps to serve the port query. Drivers are ensured by the IB core that the port attributes passed to the port query verb implementation are zero, and hence we removed the zeroing from the drivers. This patch doesn't add any new functionality. Signed-off-by:

Current code didn't modify the QP state to error because it queried the QP state as a bitmap while it isn't. So the code never got executed. This patch fixes this and queries for each QP state respectively and not at once via a bitmask. Signed-off-by:
