2024-05-30RDMA/bnxt_re: Allow MSN table capability checkSelvin Xavier1-0/+1
FW reports the HW capability to use PSN table or MSN table and driver/library need to select it based on this capability. Use the new capability instead of the older capability check for HW retransmission while handling the MSN/PSN table. FW report zero (PSN table) for older adapters to maintain backward compatibility. Also, Updated the FW interface structures to handle the new fields.

2023-08-07RDMA/bnxt_re: Fix the sideband buffer size handling for FW commandsSelvin Xavier1-32/+31
bnxt_qplib_rcfw_alloc_sbuf allocates 24 bytes and it is better to fit on stack variables. This way we can avoid unwanted kmalloc call. Call dma_alloc_coherent directly instead of wrapper bnxt_qplib_rcfw_alloc_sbuf. Also, FW expects the side buffer needs to be aligned to BNXT_QPLIB_CMDQE_UNITS(16B). So align the size to have the extra padding bytes.

2023-05-12RDMA/bnxt_re: Fix the page_size used during the MR creationSelvin Xavier1-4/+3
Driver populates the list of pages used for Memory region wrongly when page size is more than system page size. This is causing a failure when some of the applications that creates MR with page size as 2M. Since HW can support multiple page sizes, pass the correct page size while creating the MR. Also, driver need not adjust the number of pages when HW Queues are created with user memory. It should work with the number of dma blocks returned by ib_umem_num_dma_blocks.

At top level there are three major data structure addition. viz bnxt_qplib_hwq_attr, bnxt_qplib_sg_info and bnxt_qplib_tqm_ctx Intorduction of first data structure reduces the arguments list to bnxt_re_alloc_init_hwq() function. There are changes all over the driver code to incorporate this new structure. The caller needs to fill the attribute data structure and pass to this function. The second data structure is to pass memory region description viz. sghead, page_size and page_shift. There are changes all over the driver code to initialize bnxt_re_sg_info data structure. The new data structure helps to reduce the argument list of __alloc_pbl() function call. Till now the TQM rings related members were not collected under any specific data-structure making it hard to manage. The third data sctructure bnxt_qplib_tqm_ctx is added to refactor the TQM queue allocation and initialization.

This merge resolves those conflicts and provides a unified base upon which ongoing development for 4.17 can be based.

2018-01-18RDMA/bnxt_re: Add support for MRs with Huge pagesSomnath Kotur1-2/+10
Depending on the OS page-table configurations, applications may request MRs which has page size alignment other than 4K Underlying provider driver needs to adjust its PBL boundaries according to the incoming page boundaries in the PA list. Adding a capability to register MRs having pages-sizes other than 4K (Hugepages).

2018-01-17RDMA/bnxt_re: Add support for query firmware versionSelvin Xavier1-1/+21
The device now reports firmware version thus, removing the hard coded values of the FW version string and redundant fw_rev hook from sysfs. Adding code to query firmware version from underlying device and report it through the kernel verb to get firmware version string.

2018-01-17RDMA/bnxt_re: Enable RoCE on virtual functionsSelvin Xavier1-2/+35
RoCE can be used by virtual functions (VFs) as well. Adding code changes to allow resource reservation, initialization and avail the resources to the RDMA applications running on those VFs. Currently, fifty percent of the total available resources are reserved for PF and remaining are equally divided among active VFs.

Current implementation does not program vlan header insertion in RoCE packet if no vlan is configured. Firmware does not add prority when there is no vlan tag in the packet. Modify the code to insert vlan header when PFC is enabled on the interface.

2017-07-20RDMA/bnxt_re: Report supported value to IB stack in query_deviceSelvin Xavier1-0/+2
- Report supported value for max_mr_size to IB stack in query_device. Also, check and log if MR size requested by application in reg_user_mr() is greater than value currently supported by driver. - Report only 4K page size support for now - Fix Max_QP value returned by ibv_devinfo -vv. In case of PF, FW reserves 129 QPs for creating QP1s of VFs and PF. So the max_qp value reported by FW for PF doesn'tt include the QP1. Fixing this issue by adding 1 with the value reported by FW.

2017-06-14RDMA/bnxt_re: HW workarounds for handling specific conditionsEddie Wai1-0/+5
This patch implements the following HW workarounds 1. The SQ depth needs to be augmented by 128 + 1 to avoid running into an Out of order CQE issue 2. Workaround to handle the problem where the HW fast path engine continues to access DMA memory in retranmission mode even after the WQE has already been completed. If the HW reports this condition, driver detects it and posts a Fence WQE. The driver stops reporting the completions to stack until it receives completion for Fence WQE.
