Subject: [PATCH] drm/amdgpu: Support 57bit fault address for GFX 12.1.0
Date: Wed, 10 Dec 2025 02:14:03 -0500	[thread overview]
Message-ID: <20251210071415.19983-9-alexander.deucher@amd.com> (raw)
In-Reply-To: <20251210071415.19983-1-alexander.deucher@amd.com>

The gmc fault virtual address is up to 57bit for 5 level page table,
this also works with 48bit virtual address for 4 level page table.
