From 0ff382261371f76411c8a74d3feea89948af3b81 Mon Sep 17 00:00:00 2001 From: Lijo Lazar Date: Mon, 2 Sep 2024 11:20:22 +0530 Subject: [PATCH 0196/5403] drm/amdgpu: Add interface for TOS reload cases Add interface to check if a different TOS needs to be loaded than the one which is which is already active on the SOC. Presently the interface is restricted to specific variants of PSPv13.0.
