PCI resources/irq allocation cross-arch consolidation

Session information has not yet been published for this event.


One Line Summary

Discuss and draft a plan to consolidate PCI
resources (memory, IO, IRQs) management across architectures.


PCI resource allocation (claiming and assignment) and legacy IRQ assignment are currently done on a per arch basis even though there is nothing arch specific in them. This session will draft a plan to consolidate resource allocation and IRQ assignment across arches.
