Bjorn, Yijing,
I've just realized that patch c167caf8d174 (PCI/MSI: Remove useless
bus->msi assignment) completely breaks MSI on arm64 when using the new
MSI stacked domain:
Sorry, this is my first part to refactor MSI related code, now
how to get pci msi_controller depends arch functions(pcibios_msi_controller() or
arch_setup_msi_irq()), we are working on generic pci_host_bridge, after that,
we could eventually eliminate MSI arch functions and find pci dev 's msi controller
by pci_host_bridge->get_msi_controller().
Marc, could you tell me what pci host driver in your test platform ?
I'm using pci-host-generic (with a couple of patches to help it fit the
new "generic pci" infrastructure).
This lives at:
git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git
irq/arm64-pci
Thanks, I would have a look at it.
Thanks,
M.
