Subject: [PATCH v3 0/3] Rust scatterlist abstractions
Date: Sat, 10 Jun 2023 18:49:06 +0800 [thread overview]
Message-ID: <20230610104909.3202958-1-changxian.cqs@antgroup.com> (raw)
Hi All!
This is a version of scatterlist abstractions for Rust drivers.
Scatterlist is used for efficient management of memory buffers, which is
essential for many kernel-level operations such as Direct Memory Access
(DMA) transfers and crypto APIs.
This patch should be a good start to introduce the crypto APIs for Rust
drivers and to develop cipher algorithms in Rust later.
Changelog:
----------
v2 -> v3:
- Use `addr_of!` to avoid creating a reference to uninit memory.
- Mark `ScatterList::as_ref` and `ScatterList::as_mut` as unsafe.
- Revise some typos and check with `scripts/checkpatch.pl --codespell`.
- Add `# Errors` doc comment to some methods of `SgTable`.
v1 -> v2:
- Split the old patch into smaller parts.
- Remove the selftest module, and place those use cases in the doc.
- Repair some invalid hyperlinks in the doc.
- Put some `cfgs` inside functions to avoid boilerplate.
