Is it possible to receive PCIExpress_MSI_INTn (event number 17) Message signaled interrupt mode as specified in Figure 7-32 by ARM CorePac and C66x CorePac simultaneously?

Hi,

From the datasheet of K2L,

For DSP, it is 17 PCIE_0_INT4_PLUS_N PCIE_0 MSI interrupt
yes, the MSI interrupt 0, 8, 16, 24 can be routed to ARM core as well simultaneously: 30 PCIE_0_INT4 PCIe_0 MSI interrupt

What is the purpose to send the same interrupt to both ARM and DSP? You have two ISR to handle the enable/disable and end of the interrupt this may cause race conditions.

Hi Eric,

Thanks for your response, actually, I want to handle this interrupt on DSP, but only see it on ARM, not seeing on DSP. How do I enable to route it through DSP core?

Regards,

Phong
