Currently, only SPX mode works on GFX 12.1. This patch reworks the MES initialization to get other non-SPX modes working. For example, for CPX mode, coop_enable bit needs to be set to 0. The shared command buffer initialization is also not needed in CPX mode. The shared command buffer initialization needs further improvements which will be handled in later patches.

2025-12-16drm/amdgpu: fix a job->pasid access race in gpu recoveryAlex Deucher
Avoid a possible UAF in GPU recovery due to a race between the sched timeout callback and the tdr work queue. The gpu recovery function calls drm_sched_stop() and later drm_sched_start(). drm_sched_start() restarts the tdr queue which will eventually free the job. If the tdr queue frees the job before time out callback completes, the job will be freed and we'll get a UAF when accessing the pasid. Cache it early to avoid the UAF.

For 5-level page tables, update compute vmid sh_mem_base LDS aperture and Scratch aperture base address to above 57-bit, use the same setting from gfx vmid, we can remove the duplicate macro. Update queue pdd lds_base and scratch_base to the same value as sh_mem_base setting. Then application get process apertures return the correct value to access LDS and Scratch memory for 57bit address 5-level page tables. This may pass to MES in future when mapping queue.
