PCIE MSI-X support in I.MX8QM board

[mallibeerala]

Dear Team,

I am configuring my I.MX8QM board as PCIe Root Complex, Custom Board as Endpoint.

Now I am generating MSI-X interrupt from Endpoint, I have to handle Received MSI-X interrupt in my Root complex, Is I.MX8QM board will support handling of MSI-X interrupt or not?

Here at RC side handling of MSI interrupt code only available, MSI-x code is not available.

In Dts file also only msi related properties are given, MSI-x properties not provided.

Kernel Vesion: 5.15.32.

Thanks & Regards,
Mallikarjuna

Hello,

The MX8 does  not support MSI-X but Can you try it with disabled MSI interrupts?

In u-boot:

setenv mmcargs setenv bootargs console=${console} root=${mmcroot} pci=nomsi

saveenv
