Possible to use more than 16 interrupts?

Question

Hello,  
  
if I understand the architecture correctly, I can only have 16 interrupts \[1]. Is this correct? For my current project, it would be good to have 128+ interrupts. Is there any way to achieve this? Except for aggregating interrupts and additional checking on the host/software side.

Regards and thanks.

Hi miob,  
  
We don't support more than 16 interrupts from CL to shell currently. However, Our roadmap is driven by what matters to our customers. Please send me a personal message about your application needs for having more number of interrupts. It will help us refine roadmap based on customer needs, also we can help you come-up with a solution in the current scenario.  
  
Thank you,  
Sunil.

Hi miob,  
  
Yes, the architecture supports 16 interrupts (cl_sh_apppf_irq_req\[15:0]) from the CL. As you mentioned by, aggregating interrupts and additional host software it is possible to support 128+ interrupts.  
  
Thanks,

So there are no plans for native support of more than 16 interrupts?
