[PATCH v17 0/6] Rust bindings for gem shmem

From: Lyude Paul

Date: Wed Jun 03 2026 - 15:58:07 EST


Most of this patch series has already been pushed upstream, this is just
the second half of the patch series that has not been pushed yet + some
additional changes which were required to implement changes requested by
the mailing list. This patch series is originally from Asahi, previously
posted by Daniel Almeida.

The previous version of the patch series can be found here:

https://patchwork.freedesktop.org/series/164580/

Branch with patches applied available here:

https://gitlab.freedesktop.org/lyudess/linux/-/commits/rust/gem-shmem

This patch series applies on top of drm-rust-next

Patch-series wide changes since V15:
* Fix some major rebasing errors I somehow didn't notice :(
* Drop the dependency on LazyInit, use the trick that Alice suggested
instead.
* Fix dependency ordering so that Tyr can get the vmap stuff first
without the other bits.
Patch-series wide changes since V16:
* Fix ordering one more time (SetOnce::reset() doesn't need to come
before adding vmap functions)
* Rebase against the latest DeviceContext changes from me that got
pushed.
