PS interrupt PL

Question

I am working with some legacy vhdl components and I need to find a way to coordinate the PS and the PL. Is there a way to send general interrupts from the PS to the PL.

I am using DMA interrupts from the PL to the PS, but haven't found a way to signal activity from he PS to the PL. The main problem is the vhdl starts up immediately and files queues before the PS can get started.

I couldn't find anything useful so I decided I would use a gpio line and connect it to the control pin. In the ui I just write to the gpio pin and it works well enough. I submitted a post to the xilinx zynq forum and they didn't answer with anything useful either. Just suggesting I use the gpio technique that I already found on their forum. Really, thanks for your help. I do appreciate the effort you went through to assist.
