It can be used for displaying irq-virq mapping relationship under debugfs. Meanwhile, to express these information more clearly, we also add a new member named "name" for struct irq_host. [PATCH 1/3] Add a new member name to structure irq_host [PATCH 2/3] Add irq host name for interrupt controllors [PATCH 3/3] Add irq debugfs and virq mapping for getting the virq Any feedback is welcome!

The pity is, for the 75% [1] of irq_hosts that have a device_node, they will all have to implement the name callback, because they all store the of node differently.

Is there any problem when the relationship between hosts and nodes is not 1:1? The mapping method is defined in irq_alloc_host(). If there is only one host for many nodes, then these nodes will use the same mapping. Such as iic_host, the IRQ_HOST_MAP_LINEAR is used for its all nodes. We do _not_ care which node, we just care which virq is mapped from which host's hw irq. >=20 > Anyway, I discussed with Michael today and it might be a good idea to > provide an optional device node field in the host struct that can be > used by the majority of the PICs that have one host =3D=3D one node, = that > would provide a good default for the name() function. >=20 But we have some irq host which has not OF-node bound.

Oh, I thought it would be used wherever the user gets told something about the interrupt controller -- like when the interrupt tree would be shown in sysfs (yes that's hypothetical still ;-) ) >> It's a good thing to have an of_node in the irq_host struct >> anyway, though :-) > > I posted patches for that last week.
