| Description | In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix lock warning in amdgpu_userq_fence_driver_process Fix a potential deadlock caused by inconsistent spinlock usage between interrupt and process contexts in the userq fence driver. The issue occurs when amdgpu_userq_fence_driver_process() is called from both: - Interrupt context: gfx_v11_0_eop_irq() -> amdgpu_userq_fence_driver_process() - Process context: amdgpu_eviction_fence_suspend_worker() -> amdgpu_userq_fence_driver_force_completion() -> amdgpu_userq_fence_driver_process() In interrupt context, the spinlock was acquired without disabling interrupts, leaving it in {IN-HARDIRQ-W} state. When the same lock is acquired in process context, the kernel detects inconsistent locking since the process context acquisition would enable interrupts while holding a lock previously acquired in interrupt context. Kernel log shows: [ 4039.310790] inconsistent {IN-HARDIRQ-W} -> {HARDIRQ-ON-W} usage. [ 4039.310804] kworker/7:2/409 [HC0[0]:SC0[0]:HE1:SE1] takes: [ 4039.310818] ffff9284e1bed000 (&fence_drv->fence_list_lock){?...}-{3:3}, [ 4039.310993] {IN-HARDIRQ-W} state was registered at: [ 4039.311004] lock_acquire+0xc6/0x300 [ 4039.311018] _raw_spin_lock+0x39/0x80 [ 4039.311031] amdgpu_userq_fence_driver_process.part.0+0x30/0x180 [amdgpu] [ 4039.311146] amdgpu_userq_fence_driver_process+0x17/0x30 [amdgpu] [ 4039.311257] gfx_v11_0_eop_irq+0x132/0x170 [amdgpu] Fix by using spin_lock_irqsave()/spin_unlock_irqrestore() to properly manage interrupt state regardless of calling context.
