x86/apic: Rename variables and functions related to x86_io_apic_ops

2018-02-17T10:47:45+00:00

The names of x86_io_apic_ops and its two member variables are
misleading:

The ->read() member is to read IO_APIC reg, while ->disable()
which is called by native_disable_io_apic()/irq_remapping_disable_io_apic()
is actually used to restore boot IRQ mode, not to disable the IO-APIC.

So rename x86_io_apic_ops to 'x86_apic_ops' since it doesn't only
handle the IO-APIC, but also the local APIC.

Also rename its member variables and the related callbacks.

iommu, x86: Provide irq_remapping_cap() interface

2015-06-12T09:33:52+00:00

Add a new interface irq_remapping_cap() to detect whether irq
remapping supports new features, such as VT-d Posted-Interrupts.

Export the function, so that KVM code can check this and use this
mechanism properly.
