Subject: [RFC PATCH v2 00/18] CXL Boot to Bash Documentation
Apologies for the quick turn around on v2 - I wanted to deal with
the big formatting issues very quickly before others hacked on it.
v2:
- Formatting (Jonathan)
- Cross-links
- Mild formatting and wording updates.
- Some graphs in cxl-driver to explan object relationships
---
This series converts CXL Boot to Bash Docs to Linux Kernel Docs.
I tried to break it into separate patches to make it easier for
people with specific expertise to review.
The big open TODOs:
- use-case documentation.
I only have the type-3 perspective, and only one perspective.
It would be good to have that hacked on more generally.
- memory tiering documentation.
I basically left this unfilled for now. Would like some basic
docs on at least TPP and DAMON.
- devices: CDAT explanation
It would be good to have this spelled out at least a little bit.
- platform: ACPI SRAT Generic port / initiator docs
I don't know anything about this and people say it's important.
Thank you to everyone who contributed feedback during LSF/MM
Boot-to-Bash proposal. Hopefully I incorporated most feedback,
but I may have missed some.
