* tonga_ih_get_wptr - get the IH ring buffer wptr
*
* @adev: amdgpu_device pointer
+ * @ih: IH ring buffer to fetch wptr
*
* Get the IH ring buffer wptr from either the register
* or the writeback memory buffer (VI). Also check for
* tonga_ih_decode_iv - decode an interrupt vector
*
* @adev: amdgpu_device pointer
+ * @ih: IH ring buffer to decode
+ * @entry: IV entry to place decoded information into
*
* Decodes the interrupt vector at the current rptr
* position and also advance the position.
* tonga_ih_set_rptr - set the IH ring buffer rptr
*
* @adev: amdgpu_device pointer
+ * @ih: IH ring buffer to set rptr
*
* Set the IH ring buffer rptr.
