2026-02-19drm/amdkfd: Check for NULL return valuesAndrew Martin
This patch fixes issues when the code moves forward with a potential NULL pointer, without checking. Removed one redundant NULL check for a function parameter. This check is already done in the only caller.

2026-02-12drm/amdgpu: fix sync handling in amdgpu_dma_buf_move_notifyPierre-Eric Pelloux-Prayer
Invalidating a dmabuf will impact other users of the shared BO. In the scenario where process A moves the BO, it needs to inform process B about the move and process B will need to update its page table. The commit fixes a synchronisation bug caused by the use of the ticket: it made amdgpu_vm_handle_moved behave as if updating the page table immediately was correct but in this case it's not. An example is the following scenario, with 2 GPUs and glxgears running on GPU0 and Xorg running on GPU1, on a system where P2P PCI isn't supported: glxgears: export linear buffer from GPU0 and import using GPU1 submit frame rendering to GPU0 submit tiled->linear blit Xorg: copy of linear buffer The sequence of jobs would be: drm_sched_job_run # GPU0, frame rendering drm_sched_job_queue # GPU0, blit drm_sched_job_done # GPU0, frame rendering drm_sched_job_run # GPU0, blit move linear buffer for GPU1 access # amdgpu_dma_buf_move_notify -> update pt # GPU0 It this point the blit job on GPU0 is still running and would likely produce a page fault.

2026-02-05drm/amd: Fix hang on amdgpu unload by using pci_dev_is_disconnected()Mario Limonciello
The commit 6a23e7b4332c ("drm/amd: Clean up kfd node on surprise disconnect") introduced early KFD cleanup when drm_dev_is_unplugged() returns true. However, this causes hangs during normal module unload (rmmod amdgpu). The issue occurs because drm_dev_unplug() is called in amdgpu_pci_remove() for all removal scenarios, not just surprise disconnects. This was done intentionally in commit 39934d3ed572 ("Revert "drm/amdgpu: TA unload messages are not actually sent to psp when amdgpu is uninstalled"") to fix IGT PCI software unplug test failures. As a result, drm_dev_is_unplugged() returns true even during normal module unload, triggering the early KFD cleanup inappropriately. The correct check should distinguish between: - Actual surprise disconnect (eGPU unplugged): pci_dev_is_disconnected() returns true - Normal module unload (rmmod): pci_dev_is_disconnected() returns false Replace drm_dev_is_unplugged() with pci_dev_is_disconnected() to ensure the early cleanup only happens during true hardware disconnect events.

2026-02-05drm/amdgpu: Fix memory leak in amdgpu_acpi_enumerate_xcc()Zilin Guan
In amdgpu_acpi_enumerate_xcc(), if amdgpu_acpi_dev_init() returns -ENOMEM, the function returns directly without releasing the allocated xcc_info, resulting in a memory leak. Fix this by ensuring that xcc_info is properly freed in the error paths. Compile tested only. Issue found using a prototype static analysis tool and code review.

2026-02-03drm/amdgpu: Fix double deletion of validate_listHarish Kasiviswanathan
If amdgpu_amdkfd_gpuvm_free_memory_of_gpu() fails after kgd_mem is removed from validate_list, the mem handle still lingers in the KFD idr. This means when process is terminated, kfd_process_free_outstanding_kfd_bos() will call amdgpu_amdkfd_gpuvm_free_memory_of_gpu() again resulting in double deletion. To avoid this - (a) Check if list is empty before deleting it (b) Rearragne amdgpu_amdkfd_gpuvm_free_memory_of_gpu() such that it can be safely called again if it returns failure the first time.
