RDMA/irdma: Add table based lookup for CQ pointer during an event Add a CQ table based loookup to allow quick search for CQ pointer having CQ ID in case of CQ related asynchrononous event. The table is implemented in a similar fashion to QP table. Also add a reference counters for CQ. This is to prevent destroying CQ while an asynchronous event is being processed. The memory resource table size is sized higher with this update, and this table doesn't need to be physically contiguous, so use a vzalloc vs kzalloc to allocate the table.

RDMA/irdma: Refactor HW statistics Refactor HW statistics which, - Unifies HW statistics support for all HW generations. - Unifies support of 32- and 64-bit counters. - Removes duplicated code and simplifies implementation. - Fixes roll-over handling. - Removes unneeded last_hw_stats. With new implementation, there is no separate handling and no separate arrays for 32- and 64-bit counters (offsets, regs, values). Instead, there is a HW stats map array for each HW revision, which defines HW-specific width and location of each counter in the statistics buffer. Once the statistics are gathered (either via CQP op, or by reading HW registers), counter values are extracted from the statistics buffer using the stats map and the delta between the last and new values is computed. Finally, the counter values in rdma_hw_stats are incremented by those deltas. From the OS perspective, all the counters are 64-bit and their order in rdma_hw_stats->value[] array, as well as in irdma_hw_stat_names[], is the same for all HW gens. New statistics should always be added at the end.

Fix this by returning the raw operation type and queue type in the CQE to irdma_process_cqe and add 2 helpers set_ib_wc_op_sq set_ib_wc_op_rq to map IRDMA HW op types to IB op types. Note that for iWARP, only Write with Immediate is supported so the opcode can only be IB_WC_RECV_RDMA_WITH_IMM when there is immediate data present.

Implement a SW mechanism to generate completions for any outstanding WR's after the QP is modified to error. This is accomplished by starting a delayed worker after the QP is modified to error and the HW flush is performed. The worker will generate completions that will be returned to the application when it polls the CQ. This mechanism only applies to Kernel applications.

When it is allocated, the size (in bytes) is computed by: size_in_bits >> 3 There are 2 issues (numbers bellow assume that longs are 64 bits): - there is no guarantee here that 'pchunk->bitmapmem.size' is modulo BITS_PER_LONG but bitmaps are stored as longs (sizeofbitmap=8 bits will only allocate 1 byte, instead of 8 (1 long)) - the number of bytes is computed with a shift, not a round up, so we may allocate less memory than needed (sizeofbitmap=65 bits will only allocate 8 bytes (i.e. 1 long), when 2 longs are needed = 16 bytes) Fix both issues by using 'bitmap_zalloc()' and remove the useless 'bitmapmem' from 'struct irdma_chunk'.

RDMA/irdma: Skip CQP ring during a reset Due to duplicate reset flags, CQP commands are processed during reset. This leads CQP failures such as below: irdma0: [Delete Local MAC Entry Cmd Error][op_code=49] status=-27 waiting=1 completion_err=0 maj=0x0 min=0x0 Remove the redundant flag and set the correct reset flag so CPQ is paused during reset Fixes: 8498a30e1b94 ("RDMA/irdma: Register auxiliary driver and implement private channel OPs") Link: https://lore.kernel.org/r/20210916191222.824-2-shiraz.saleem@intel.com Reported-by: LiLiang <liali@redhat.com> Signed-off-by: Sindhu Devale <sindhu.devale@intel.com> Signed-off-by: Shiraz Saleem <shiraz.saleem@intel.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>

RDMA/irdma: Fix potential overflow expression in irdma_prm_get_pbles Coverity reports a signed 32-bit overflow on "1 << pprm->pble_shift" when used expression to compute bits_needed that expects 64bit, unsigned. Fix this by using the 1ULL in the left shift operator and convert mem_size to u64.

RDMA/irdma: Store PBL info address a pointer type The level1 PBL info address is stored as u64. This requires casting through a uinptr_t before used as a pointer type. And this leads to sparse warning such as this when uinptr_t is missing: drivers/infiniband/hw/irdma/hw.c: In function 'irdma_destroy_virt_aeq': drivers/infiniband/hw/irdma/hw.c:579:23: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] 579 | dma_addr_t *pg_arr = (dma_addr_t *)aeq->palloc.level1.addr; This can be fixed using an intermediate uintptr_t, but rather it is better to fix the structure irdm_pble_info to store the address as u64* and the VA it is assigned in irdma_chunk as a void*. This greatly reduces the casting on this address.
