Subject: [PATCH rdma-next v1 0/7] Use ib_umem_find_best_pgsz() for all umems
Date: Sun, 15 Nov 2020 13:43:04 +0200 [thread overview]
Message-ID: <20201115114311.136250-1-leon@kernel.org> (raw)
From: Leon Romanovsky <leonro@nvidia.com>
Changelog:
v1:
* Added patch for raw QP
* Fixed commit messages
v0: https://lore.kernel.org/lkml/20201026132635.1337663-1-leon@kernel.org
-------------------------
From Jason:
Move the remaining cases working with umems to use versions of
ib_umem_find_best_pgsz() tailored to the calculations the devices
requires.
Unlike a MR there is no IOVA, instead a page offset from the starting page
is possible, with various restrictions.
Compute the best page size to meet the page_offset restrictions.
Thanks
Jason Gunthorpe (7):
RDMA/mlx5: Use ib_umem_find_best_pgoff() for SRQ
RDMA/mlx5: Use mlx5_umem_find_best_quantized_pgoff() for WQ
RDMA/mlx5: Directly compute the PAS list for raw QP RQ's
RDMA/mlx5: Use mlx5_umem_find_best_quantized_pgoff() for QP
RDMA/mlx5: mlx5_umem_find_best_quantized_pgoff() for CQ
RDMA/mlx5: Use ib_umem_find_best_pgsz() for devx
RDMA/mlx5: Lower setting the umem's PAS for SRQ
