  - amd/amdkfd增強交換磁碟分割中的 kfd 處理程序檢查目前交換磁碟分割僅檢查 kfd_processes_table 是否為空。 kfd_process_notifier_release 中的 kfd_prcesses_table 項目遭刪除但 kfd_process_wq_release 中存在 kfd_process 終止。請考慮以下兩個處理程序：處理程序 A (workqueue) -> kfd_process_wq_release -> 存取 kfd_node 成員處理程序 B 切換磁碟分割 -> amdgpu_xcp_pre_partition_switch -> amdgpu_amdkfd_device_fini_sw -> kfd_node 中斷。處理程序 A 和 B 可能觸發爭用情形如 dmesg 記錄中所示。此修補程式透過新增不可部分完成的 kfd_process 計數器 kfd_processes_count 來解決爭用其會隨著 kfd 處理程序的建立而遞增當 kfd_process_wq_release 完成時遞減。 v2放置每個 kfd_dev 的 kfd_processes_count、將遞減項目移至 kfd_process_destroy_pdds 和錯誤修正。(Philip Yang) [3966658.307702] 除法錯誤0000 [#1] SMP NOPTI [3966658.350818] i10nm_edac [3966658.356318] CPU124 PID 38435 通訊kworker/124:0 Kdump 載入污染 [3966658.356890] 工作佇列 kfd_process_wq kfd_process_wq_release [amdgpu] [3966658.362839] nfit [3966658.366457] RIP: 0010:kfd_get_num_sdma_engines+0x17/0x40 [amdgpu] [3966658.366460] 代碼00 00 e9 ac 81 02 00 66 66 2e 0f 1f 84 00 00 00 00 00 90 90 00 00 00 0f 1f 44 00 00 48 8b 4f 08 48 8b b7 00 01 00 00 8b 81 58 26 03 00 99 <f7> 為 b8 01 00 00 80 b9 70 2e 00 00 00 74 0b 83 f8 02 ba 02 00 ] 0 [] 0 [3966658.3809670 x86_pkg_temp_thermal [3966658.391529] RSP0018:ffffc900a0edfdd8 EFLAGS00010246 [3966658.391531] RAX
