Hi, I'm posting this now, instead of with the upcoming full Hopper/Blackwell series, because this includes some HAL improvements here that will undoubtedly interact "a little bit" with Timur Tabi's Turing support patchset [1].
Changes in v2: 0) Rebased on top of today's drm-rust-next. 1) Use a new FbRange newtype, in order to clean up the implementation of printing ranges with sizes. (Thanks to Alex Courbot's suggestion.) 2) Combined the Hopper and Blackwell HAL additions, into a single patch, as recommended by Timur Tabi. 3) Used a separate patch to change the "use" lines to vertical format. That patch is already a commit in drm-rust-next, so this series builds on top of that. 4) Dropped one patch entirely, because the boot0/boot42 commits fixed up everything already. As implied above, this is based on top of today's drm-rust-next. There is also a branch, for convenience in reviewing: https://github.com/johnhubbard/linux/tree/nova-core-blackwell-prereqs-v2 [1] https://lore.kernel.org/[email protected] ************************************************************************ Here's the original cover letter, edited slightly (removed the link to the v0 series, to avoid anyone going there by mistake): I've based these Hopper/Blackwell prerequisites on top of Joel's and Alex's changes, and also on top of my recent boot0/boot42 changes. This makes it easier for both Timur Tabi to post his Turing support (which he's about ready to do), and for me to post the actual Hopper/Blackwell support, without generating conflicts. Testing: This works as expected on Ampere and Blackwell (bare metal), on my local test machine.
