Is there a way to interrupt the i.MX6 via PCIe when it is operating in endpoint (EP) mode? When the device is setup in root complex (RC) mode there are a variety of spec-based PCIe interrupt sources, however, I can't seem to find a method to interrupt the processor over the PCIe bus when it is operating in EP mode.
There are the software interrupts available in the ARM MPCore, however, these are located on a bus internal to the ARM core. Therefore, I won't be able to access them from the RC device. Is there another set of software interrupts available when the i.MX6 is in EP mode that I can trigger from the RC device?
