Minor change of i.MX53 VPU decoder flow

Hi chip experts,

 

I found 2 descriptions about vpu_IsBusy() in i.MX5x_Linux_VPU_API.pdf.
  (1) Figure 4. Decoder Operation Flow on p41
  (2) 4.3.3.5 Completion of Picture Decoding on p86

 

Is it possible to replace vpu_IsBusy() call with vpu_WaitForInt()?
Because I prefer interrupt rather than polling.

 

If yes, are any modifications need except above swap?

 

Can anyone help me?

Thanks.
