From b9616d9721bf8a56d5038e85d2ebbe0ec9d56a94 Mon Sep 17 00:00:00 2001 From: Joel Fernandes Date: Fri, 20 Mar 2026 00:57:10 -0400 Subject: rust: gpu: Add GPU buddy allocator bindings Add safe Rust abstractions over the Linux kernel's GPU buddy allocator for physical memory management. The GPU buddy allocator implements a binary buddy system useful for GPU physical memory allocation. nova-core will use it for physical memory allocation.
