Any chance you could give me a hand with the remaining three users within the amdgpu driver? I don't know if the in_interrupt() check can be limited to certain callers. What I noticed while tracing v5.10 is this: | Xorg-2257 [007] d... 57261.620043: amdgpu_device_wreg: 0x699f, 0x00001bcf, 0x00000100 | => trace_event_raw_event_amdgpu_device_wreg | => amdgpu_device_wreg.part.0 | => dce110_arm_vert_intr | => dce110_vblank_set | => dm_enable_vblank | => drm_vblank_enable | => drm_vblank_get | => drm_wait_vblank_ioctl | => drm_ioctl_kernel | => drm_ioctl | => amdgpu_drm_ioctl | => __x64_sys_ioctl | => do_syscall_64 | => entry_SYSCALL_64_after_hwframe I think that amdgpu_device_wreg() -> amdgpu_kiq_wreg() could be invoked. It doesn't here because amdgpu_sriov_runtime() is false. The trace says `d' which means interrupts are disabled but in_interrupt() will return false in this case (no IRQ/softirq).
