Title
drm/amdgpu: Add a lock when accessing the buddy trim function
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Add a lock when accessing the buddy trim function When running YouTube videos and Steam games simultaneously, the tester found a system hang / race condition issue with the multi-display configuration setting. Adding a lock to the buddy allocator's trim function would be the solution. <log snip> [ 7197.250436] general protection fault, probably for non-canonical address 0xdead000000000108 [ 7197.250447] RIP: 0010:__alloc_range+0x8b/0x340 [amddrm_buddy] [ 7197.250470] Call Trace: [ 7197.250472] <TASK> [ 7197.250475] ? show_regs+0x6d/0x80 [ 7197.250481] ? die_addr+0x37/0xa0 [ 7197.250483] ? exc_general_protection+0x1db/0x480 [ 7197.250488] ? drm_suballoc_new+0x13c/0x93d [drm_suballoc_helper] [ 7197.250493] ? asm_exc_general_protection+0x27/0x30 [ 7197.250498] ? __alloc_range+0x8b/0x340 [amddrm_buddy] [ 7197.250501] ? __alloc_range+0x109/0x340 [amddrm_buddy] [ 7197.250506] amddrm_buddy_block_trim+0x1b5/0x260 [amddrm_buddy] [ 7197.250511] amdgpu_vram_mgr_new+0x4f5/0x590 [amdgpu] [ 7197.250682] amdttm_resource_alloc+0x46/0xb0 [amdttm] [ 7197.250689] ttm_bo_alloc_resource+0xe4/0x370 [amdttm] [ 7197.250696] amdttm_bo_validate+0x9d/0x180 [amdttm] [ 7197.250701] amdgpu_bo_pin+0x15a/0x2f0 [amdgpu] [ 7197.250831] amdgpu_dm_plane_helper_prepare_fb+0xb2/0x360 [amdgpu] [ 7197.251025] ? try_wait_for_completion+0x59/0x70 [ 7197.251030] drm_atomic_helper_prepare_planes.part.0+0x2f/0x1e0 [ 7197.251035] drm_atomic_helper_prepare_planes+0x5d/0x70 [ 7197.251037] drm_atomic_helper_commit+0x84/0x160 [ 7197.251040] drm_atomic_nonblocking_commit+0x59/0x70 [ 7197.251043] drm_mode_atomic_ioctl+0x720/0x850 [ 7197.251047] ? __pfx_drm_mode_atomic_ioctl+0x10/0x10 [ 7197.251049] drm_ioctl_kernel+0xb9/0x120 [ 7197.251053] ? srso_alias_return_thunk+0x5/0xfbef5 [ 7197.251056] drm_ioctl+0x2d4/0x550 [ 7197.251058] ? __pfx_drm_mode_atomic_ioctl+0x10/0x10 [ 7197.251063] amdgpu_drm_ioctl+0x4e/0x90 [amdgpu] [ 7197.251186] __x64_sys_ioctl+0xa0/0xf0 [ 7197.251190] x64_sys_call+0x143b/0x25c0 [ 7197.251193] do_syscall_64+0x7f/0x180 [ 7197.251197] ? srso_alias_return_thunk+0x5/0xfbef5 [ 7197.251199] ? amdgpu_display_user_framebuffer_create+0x215/0x320 [amdgpu] [ 7197.251329] ? drm_internal_framebuffer_create+0xb7/0x1a0 [ 7197.251332] ? srso_alias_return_thunk+0x5/0xfbef5 (cherry picked from commit 3318ba94e56b9183d0304577c74b33b6b01ce516)
