Subject: [PATCH 0/4] gpu: nova-core: obtain and display VRAM amount
Date: Tue, 09 Jun 2026 17:03:58 +0900	[thread overview]
Message-ID: <20260609-boot-vram-v1-0-d9382610507a@nvidia.com> (raw)

This series performs some light refactoring required to be able to
initialize members of the `Gpu` struct from GSP commands, and makes use
of that refactoring to obtain and store the amount of VRAM on the
device.

This is useful as probe-time information to be displayed, but will also
become a parameter that can be queried from user-space once the nova-drm
to nova-core bridge is established.
