Subject: [PATCH 4/7] drm/xe/display: Avoid dereferencing xe_ggtt_node
Date: Tue, 21 Oct 2025 14:18:18 +0200	[thread overview]
Message-ID: <20251021121814.2193153-13-dev@lankhorst.se> (raw)
In-Reply-To: <20251021121814.2193153-9-dev@lankhorst.se>

Start using xe_ggtt_node_addr, and avoid comparing the base offset
as vma->node is dynamically allocated.

Also sneak in a xe_bo_size() for stolen, too small to put as separate commit.
