[PATCH v2 1/3] drm/amdgpu: gfx_v11_0_cp_ecc_error_irq_funcs is not needed any more

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The gfx.cp_ecc_error_irq is retired in gfx11. In gfx_v11_0_hw_fini still
use amdgpu_irq_put to disable this interrupt, which caused the call trace
in this function.
