Hi Likun,
Let's take a step back to check with Alex S why he add the ASIC type check here. I'm under impression there was a change to use navi10_ih block for arcturus, but haven't followed up closely yet.
Regards,
Hawking

Subject: [PATCH] amdgpu/drm: cleanup navi10 ih logic about older ASIC
From: Likun Gao <Likun.Gao@xxxxxxx>
The ASIC which is older than navi10 will not call into navi10_ih related function, so cleanup the related code path.
