Hello,
I am wondering whether msi / msix should work on PPC405EX. A call to pci_en=
able_msi returns: -38 / ENOSYS, function not implemented.
Can someone tell me if I am missing out something or if msi is indeed not i=
mplemented on this platform?
Thanks,=20

It doesn't work there yet, as it has not been implemented. There are patches
for MSI on 460SX now, and those could probably be leveraged once they're merged.
