MSI chip in this series is to setup MSI irq, including IRQ allocation, Map,
compose MSI msg ..., in different platform, many arch specific MSI irq details in it.
It's difficult to extract the common data and code.

I have a plan to rework MSI related irq_chips in kernel, PCI and Non-PCI, currently,
HPET, DMAR and PCI have their own irq_chip and MSI related functions, write_msi_msg(),
mask_msi_irq(), etc... I want to extract the common data set for that, so we can
remove lots of unnecessary MSI code.

That makes sense. Can you please make sure that this does not conflict
with the ongoing work Jiang is doing in the x86 irq area with
hierarchical irqdomains to distangle layered levels like MSI from the
underlying vector/irqremap mechanics.

Yes, I'm reviewing Jiang hierarchical irqdomains series, I'm interested in that changes.

Thanks!
