[RFC v5 09/17] irqchip/gic-v3-its: ITS advertises MSI_FLAG_IRQ_REMAPPING

Show all headers | View raw

The ITS is the first ARM MSI controller advertising the new
MSI_FLAG_IRQ_REMAPPING flag. It does so because it supports
interrupt translation service. This HW support offers isolation
of MSIs, feature used when using KVM device passthrough.
