Subject: [PATCH v2 0/3] rust, nova-core: add DeviceSize trait for SZ_* constants
Date: Wed, 11 Mar 2026 20:15:04 -0700 [thread overview]
Message-ID: <20260312031507.216709-1-jhubbard@nvidia.com> (raw)
Changes in v2:
* Replaced flat SZ_*_U64 constants with a DeviceSize trait that
provides SZ_* as associated constants on u32 and u64.
* A define_sizes! macro generates everything from one list of names.
* Added Alignment::from_u64() so alignment values can be constructed
from DeviceSize constants without falling back to usize variants.
* Rebased onto drm-rust-next. No longer depends on the Blackwell
patchset.
v1 is here:
