[PATCH v2 0/2] gpu: nova-core: convert to kernel bitfield macro and remove local variant

From: Alexandre Courbot

Date: Tue Jun 30 2026 - 20:15:54 EST


Now that the kernel-wide bitfield macro is available, it is time for the
Nova-local version to be removed.

The first patch converts all uses of the local macro to the global one.
This involves redefining all bitfields since the syntax has changed, and
taking into account the use of `Bounded`.

The second patch removes the now unused Nova-local bitfield macro.

This is a follow-up to [1] containing the Nova patches that have been
dropped after [2].

This series applies on top of `drm-rust-next`. Since it has been
reviewed/acked I am planning on merging it soon; this revision is mostly
to address the Sashiko feedback of v1.
