if sys/biso hwi can establish pcie msi interrupt

Sunny

hi TI professors,

I want to use DSP core0 as the RC communication with FPGA by PCIe. I establish sys/bios realize the ipc communication. I wanna know if I can use hwi to receive the pcie msi interrupt sent by fpga?

Hello!
One may use Core0 to setup PCIe stuff at initialization stage. Afterwards MSIs can be used to trigger HWIs per core. Generally, all MSI vectors are split in groups, and each group is targeted to one core of the SoC.
