From f1bd7119ac4c98fc2f0ddf5a6d851de66bc5f62f Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Mon, 22 Jun 2026 22:30:10 +0900 Subject: [PATCH] gpu: drm: nova: depend on nova-core and use its symbols Make nova-core a build dependency of nova-drm, so its crate metadata is available and up-to-date when the latter is built. This is intended to be a workaround until the build system supports Rust cross-crate dependencies natively.
