* RDMA/mana_ib: use the correct page size for mapping user-mode doorbell pageLong Li2024-09-021-3/+3
| | | | | | | | | | | When mapping doorbell page from user-mode, the driver should use the system page size as this memory is allocated via mmap() from user-mode.

* RDMA/mana_ib: use the correct page table index based on hardware page sizeLong Li2024-09-021-1/+1
| | | | | | | | | | | MANA hardware uses 4k page size. When calculating the page table index, it should use the hardware page size, not the system page size.

* RDMA/mana_ib: Process QP error events in mana_ibKonstantin Taranov2024-06-091-2/+29
| | | | | | | | | | | Process QP fatal events from the error event queue. For that, find the QP, using QPN from the event, and then call its event_handler. To find the QPs, store created RC QPs in an xarray.

* RDMA/mana_ib: Use virtual address in dma regions for MRsKonstantin Taranov2024-03-071-9/+31
| | | | | | | | | | | | | | | | | Introduce mana_ib_create_dma_region() to create dma regions with iova for MRs. It allows creating MRs with any page offset. Previously, only page-aligned addresses worked. For dma regions that must have a zero dma offset (e.g., for queues), mana_ib_create_zero_offset_dma_region() is added. To get the zero offset, ib_umem_find_best_pgoff() is used with zero pgoff_bitmask.
