Subject: [PATCH 19/23] drm/amdgpu/gmc11: use SDMA for gart TLB invalidation
Date: Fri, 11 Sep 2026 13:55:40 -0400	[thread overview]
Message-ID: <20260911175544.1314467-20-alexander.deucher@amd.com> (raw)
In-Reply-To: <20260911175544.1314467-1-alexander.deucher@amd.com>

Use SDMA rather than MES/MMIO.  This is recommended by
the hubs team and aligns with what other OSes do.
