Subject: [PATCH for-next 0/3] RDMA/erdma: Add hierachical MTT support
Date: Thu, 17 Aug 2023 18:21:48 +0800 [thread overview]
Message-ID: <20230817102151.75964-1-chengyou@linux.alibaba.com> (raw)
Currently, erdma only supports 0-level or 1-level MTT, which limits the
maximum length of MR. It fails to meet the requirements in some scenarios.
Therefore, we implement hierachical MTT to support 2-level and 3-level
MTT, so that users can register MRs large to 64G to erdma devices.
- #1 ~ #2 make some preparations, such as renaming certain variables and
refactoring the storage structure of MTT.
- #3 implements the hierachical MTT.
