Target Qoriq LS1043A : I would to implement MSI-X interrupts on my PCI express interface. In the reference manual of Qoriq LS1043a, I have found information about "Legacy interrupts", "MSI interrupts", but nothing about "MSI-X" interrupts.
I think that "MSI-X" interrupts are not supported, but I didn't find any information about. Any help to confirm that ?
> I think that "MSI-X" interrupts are not supported
Correct, only MSI extension is supported.
Please refer to the LS1043A RM describing the MSI mechanism implementation:
11.3.54 Shared Message Signaled Interrupt Index Register (SCFG_G0MSIIR)
11.3.55 Shared Message Signaled Interrupt Register (SCFG_G0MSIR)
26.1.1.1 PCI Express MSI implementation
