From 2318336573c51748bd2089a835242c70be6850cf Mon Sep 17 00:00:00 2001 From: "Jesse.Zhang" Date: Tue, 5 Aug 2025 11:26:15 +0800 Subject: [PATCH 5020/5403] drm/amdgpu: Add preempt and restore callbacks to userq funcs Add two new function pointers to struct amdgpu_userq_funcs: - preempt: To handle preemption of user mode queues - restore: To restore preempted user mode queues These callbacks will allow the driver to properly manage queue preemption and restoration when needed, such as during context switching or priority changes.
