From 9a9e87d15297ce72507178e93cbb773510c061cd Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 9 Jun 2025 12:13:04 -0400 Subject: [PATCH 4043/5403] drm/amdgpu/sdma: handle paging queues in amdgpu_sdma_reset_engine() Need to properly start and stop paging queues if they are present. This is not an issue today since we don't support a paging queue on any chips with queue reset.
