[PATCH 0/7] KVM: irqfd generalization prepare patch set

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The concept of an irqfd and interrupt routing are nothing particularly tied
into the IOAPIC implementation. In fact, most of the code already is perfectly
generic.

This patch set decouples most bits of the existing irqchip and irqfd
implementation to make it reusable for non-IOAPIC platforms, like the PPC MPIC.

I also have a patch that implements working irqfd support on top of these,
but that requires the in-kernel MPIC implementation to go upstream first, so
I'm holding off on it until we settled everything there, so the concept
certainly does work.
