* Values used in determining the allocation of IRQ values among

|
||||
* indices into a interrupt source array to map I/O interrupts to a
|
||||
* device interrupt source whether it be a pin on an interrupt
|
||||
* controller or an MSI interrupt. The 16 ISA IRQs are assigned fixed
|
||||
* IDT vectors, but all other device interrupts allocate IDT vectors
|
||||
* on demand. Currently we have 191 IDT vectors available for device
|
||||
* interrupts on each CPU. On many systems with I/O APICs, a lot of
|
||||
* the IRQs are not used, so the total number of IRQ values reserved
|
||||
* can exceed the number of available IDT slots.
|
||||
*
|
||||
* The first 16 IRQs (0 - 15) are reserved for ISA IRQs. Interrupt
|
||||
* pins on I/O APICs for non-ISA interrupts use IRQ values starting at
|
||||
* IRQ 17. This layout matches the GSI numbering used by ACPI so that
|
||||
* IRQ values returned by ACPI methods such as _CRS can be used
|
||||
* directly by the ACPI bus driver.
|
||||
*
|
||||
* MSI interrupts allocate a block of interrupts starting at the end
|
||||
* of the I/O APIC range. When running under the Xen Hypervisor, an
|
||||
* additional range of IRQ values are available for binding to event
|
||||
* channel events.
