Description

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix calltrace warning in amddrm_buddy_fini The following call trace is observed when removing the amdgpu driver, which is caused by that BOs allocated for psp are not freed until removing. [61811.450562] RIP: 0010:amddrm_buddy_fini.cold+0x29/0x47 [amddrm_buddy] [61811.450577] Call Trace: [61811.450577] <TASK> [61811.450579] amdgpu_vram_mgr_fini+0x135/0x1c0 [amdgpu] [61811.450728] amdgpu_ttm_fini+0x207/0x290 [amdgpu] [61811.450870] amdgpu_bo_fini+0x27/0xa0 [amdgpu] [61811.451012] gmc_v9_0_sw_fini+0x4a/0x60 [amdgpu] [61811.451166] amdgpu_device_fini_sw+0x117/0x520 [amdgpu] [61811.451306] amdgpu_driver_release_kms+0x16/0x30 [amdgpu] [61811.451447] devm_drm_dev_init_release+0x4d/0x80 [drm] [61811.451466] devm_action_release+0x15/0x20 [61811.451469] release_nodes+0x40/0xb0 [61811.451471] devres_release_all+0x9b/0xd0 [61811.451473] __device_release_driver+0x1bb/0x2a0 [61811.451476] driver_detach+0xf3/0x140 [61811.451479] bus_remove_driver+0x6c/0xf0 [61811.451481] driver_unregister+0x31/0x60 [61811.451483] pci_unregister_driver+0x40/0x90 [61811.451486] amdgpu_exit+0x15/0x447 [amdgpu] For smu v13_0_2, if the GPU supports xgmi, refer to commit f5c7e7797060 ("drm/amdgpu: Adjust removal control flow for smu v13_0_2"), it will run gpu recover in AMDGPU_RESET_FOR_DEVICE_REMOVE mode when removing, which makes all devices in hive list have hw reset but no resume except the basic ip blocks, then other ip blocks will not call .hw_fini according to ip_block.status.hw. Since psp_free_shared_bufs just includes some software operations, so move it to psp_sw_fini.
