Subject: [PATCH v3 7/7] drm: nova: Expose a render node
Date: Thu, 23 Jul 2026 16:30:45 +1000	[thread overview]
Message-ID: <20260723063046.1265791-8-apopple@nvidia.com> (raw)
In-Reply-To: <20260723063046.1265791-1-apopple@nvidia.com>

nova-drm currently only exposes a primary node even though all of its
ioctls are already marked DRM_RENDER_ALLOW. Set the DRIVER_RENDER
feature so that a render node (/dev/dri/renderDXX) is created as well.

This is required to allow render and compute clients to interact with
nova-drm.
