Hi,
I believe someone working on NEWBUS-ifying ISA-PnP.
How will they implement it?
I think current framework is like this.
++ ++
...|ISA DEV | |ISA-hint|-This device provides
++ ++what device is connected
| || the ISA bus.
--ISA--
|
+-+
|Nexus or ISAB|

1. Is the figure true?
2.If so,where do they attach ISA-PnP mechanism?
attach it like ISA-hint device,modify ISA Bus code or isapnpbus
other than ISA-Bus?
3.How do I add ISA-PnP device?
4.How do I add PnP mechanism other than ISA-PnP.
This diagram is correct. The ISA-PnP driver is similar to the ISA-hint
driver in that it doesn't probe and attach devices itself but creates
devices which other drivers can attach to. I have modified the api between
the ISA device enumerators (ISA-hint and ISA-PnP) to allow them to specify
a set of resource alternatives and a callback function which can select a
single alternative.
Other PnP mechanisms should fit into this scheme easily. I had ACPI in
mind when I was putting this system together.
