2024-03-07RDMA/mana_ib: Use virtual address in dma regions for MRsKonstantin Taranov1-2/+2
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.

2024-01-25RDMA/mana_ib: Introduce mdev_to_gc helper functionKonstantin Taranov1-10/+3
Use a helper function to access gdma_context from mana_ib_dev. This patch removes code repetitions as well as removes the need to explicitly use gdma_dev, which was error-prone.
