Hi,
This is based on today's drm-rust-next. A git branch is here:
https://github.com/johnhubbard/linux/tree/nova-core-blackwell-v6
It's been tested on Turing (new!), Ampere and Blackwell:
NovaCore 0000:e1:00.0: GPU name: NVIDIA GeForce GTX 1650
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 v6:
* Rebased onto drm-rust-next (v7.0-rc1 based).
* Dropped the first two patches from v5 (aux device fix and pdev
macros), which have since been merged independently.
* const_align_up(): reworked per review from Gary Guo, Miguel Ojeda,
and Danilo Krummrich: now returns Option<usize> instead of panicking,
takes an Alignment argument instead of a const generic, and no longer
needs the inline_const feature addition in scripts/Makefile.build.
* The rust/sizes and SZ_*_U64 patches from v5 are no longer included.
I plan to post those as a separate series that depends on this one.
Changes in v5:
* 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.
