define KernelPackage/irqbypass/description
|
||
|
|
Various virtualization hardware acceleration techniques allow bypassing or
|
||
|
|
offloading interrupts received from devices around the host kernel. Posted
|
||
|
|
Interrupts on Intel VT-d systems can allow interrupts to be received
|
||
|
|
directly by a virtual machine. ARM IRQ Forwarding allows forwarded physical
|
||
|
|
interrupts to be directly deactivated by the guest. This manager allows
|
||
|
|
interrupt producers and consumers to find each other to enable this sort of
|
||
|
|
bypass.

|
|
Support hosting fully virtualized guest machines using hardware
|
||
|
|
virtualization extensions. You will need a fairly recent
|
||
|
|
processor equipped with virtualization extensions. You will also
|
||
|
|
need to select one or more of the processor modules.
|
||
|
|
|
||
|
|
This module provides access to the hardware capabilities through
|
||
|
|
a character device node named /dev/kvm.
