After recovering from suspension, shared graphics memory will become invalid

It should be a common problem with archLinux, both Holloiso and ChimeraOS have this issue. After recovering from suspension, shared graphics memory no longer takes effect, and the GPU can only use the dedicated graphics memory set in the bios. This will cause a significant decrease in GPU performance after suspension recovery, especially in handheld devices where 16GB RAM machines default to allocating 3G dedicated graphics memory, and some large games often use graphics memory exceeding 3G, After the failure of shared memory, the FPS of these games will significantly decrease, often only reaching about half of the maximum FPS. This issue has been identified and can only be recovered by restarting the system.
