Hi,
This is based on today's linux.git. A git branch with this (plus a fix
for a CLIPPY warning on a core Rust for Linux issue which I suspect
others have already found and fixed) is here:
https://github.com/johnhubbard/linux/tree/nova-core-blackwell-v5
This is quite a large overhaul, multiple passes to fix up a lot of
issues found during review, and then I found more while doing the fixes.
Patch 1 is going to be merged separately, but is included here in order
to allow people to apply the series.
Patch 2 is going to come from Gary Guo, not here, but is included for
the same reason.
The last two patches, 37 and 38, do not need to be part of this series,
but are best applied *after* the series, in order to catch all the
cases.
There are a also a few rust/ patches that might need/want to get merged
separately.
It's been tested on Ampere and Blackwell, one each:
NovaCore 0000:e1:00.0: GPU name: NVIDIA RTX A4000
NovaCore 0000:01:00.0: GPU name: NVIDIA RTX PRO 6000 Blackwell Max-Q
Workstation Edition
Changes in v5 (in highly condensed and summarized form):
* Rebased onto linux.git master.
* Split MCTP protocol into its own module and file.
* Many Rust-based improvements: more use of types, especially. Also
used Result and Option more.
* Lots of cleanup of comments and print output and error handling.
* Added const_align_up() to rust/ and used it in nova-core. This
required enabling a Rust feature: inline_const, as recommended by
Miguel Ojeda.
* Refactoring various things, such as Gpu::new() to own Spec creation,
and several more such things.
* Fixed three Delta::ZERO busy-polls (patches 21, 24, 31) to use
non-zero sleep intervals (after just realizing that it was a bad
choice to have zero in there).
* Reduced GH100/GB100 HAL duplication. Made FSP_PKEY_SIZE/FSP_SIG_SIZE
consistent across patches. Replaced fragile architecture checks with
chipset.arch(). Renamed LIBOS_BLACKWELL.
* Narrowed the scope of some of the #![expect(dead_code)] cases,
although that really only matters within the series, not once it is
fully applied.
