[Qemu-devel] [PATCH 0/6] intc: change 'info irq' and 'info pic' to be target-agnostic

[Hervé Poussineau]

Hi,

This patchset aims at genericizing the 'info irq' and 'info pic' HMP commands, 
so
that it is available on all machines and can display details about more than one
interrupt controller per machine.

Patch 1 adds a new interface IntCtrl, which is used to:
- gather statistics for the 'info irq' command
- print some text when 'info pic' is called

Patches 2 to 4 implement IntCtrl interface on interrupt controllers which have
ad-hock code to handle 'info irq'/'info pic' commands.

Patch 5 removes ad-hock code, and replaces it by a generic version. You can get
details about multiple interrupt controllers per machine starting here.

Patch 6 makes 'info irq'/'info pic' commands available on all architectures.
For example, Alpha clipper machine is now able to display details about the
i8259 interrupt controller.
