configuration of devices logically attached to the ISA bus:
* Change the isa_attach_args to have arrays of io, mem, irq, drq
resources.
* Add a "pnpnames" and a linked list of "pnpcompatnames" to the
isa_attach_args. If either of these members are non-NULL,
direct configuration of the bus is being performed. Add an
ISA_DIRECT_CONFIG() macro to test for this.
* Drivers are not allowed to modify the isa_attach_args unless
direct configuration is not being performed and the probe fucntion
is returning success.
* Adapt device drivers -- currently, all driver probe routines return
"no match" if ISA_DIRECT_CONFIG() evaluates to true.
support the P-5064, which has a QED RM5xxx CPU soldered on.
There is some skeletal support for the P-4032 (an older board, which
had an R4xxx CPU). There are some placeholders for the P-6032, which
is their newest board, but no real code yet (the P-6032 has a different
PCI controller, the Algorithmics BONITO).
There are still some (apprently softintr-related) problems with the
algor kernel, but it works well-enough to self-host.
Kudos to Allegro Networks for loaning me a P-5064 board on which to do
the port.
