1931cf940a - Heavyweight interrupt threads on the alpha for device I/O interrupts.
- Make softinterrupts (SWI's) almost completely MI, and divorce them
  completely from the x86 hardware interrupt code.
  - The ihandlers array is now gone.  Instead, there is a MI shandlers array
    that just contains SWI handlers.
  - Most of the former machine/ipl.h files have moved to a new sys/ipl.h.
- Stub out all the spl*() functions on all architectures.

21c3015a24 * Completely rewrite the alpha busspace to hide the implementation from
the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
  which call busspace.
* Rework pci config accesses to route through the pcib device instead of
  calling a MD function directly.

With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.

e8ad1d0707 Handle (for now) trivial one level bridge case so we can get the
slot that the bridge happens to be in so we get interrupts working
on bridged cards.

aa5904a62a Coordinate with change to mcpcia_pci.c- major primary busses on each
hose are 16 PCI instances apart. This allows us to recognize secondary
PCI busses (at least to a first level) until the pci infrastructure is
fixed.

Turn on support for secondary cycles, too.  Redo debug printouts.

e3227bc7a6 Enable EISA interrupts if the mcpcia has an attached EISA bus. 2000-05-13 21:33:57 +00:00

f66ed5ddfa Change references/comments about 'secondary' to reflect that while we'd
like to see the true SRM bus number be passed to us, instead, we get FreeBSD's
PCI bus instance number (Brzzt! Wrong Answer!).

Also, once we've seen the MCPCIA that has the EISA bus on it, call
dec_kn300_cons_init just before configuring devices on this bus.

157ffa95ef Pass the vector on thru instead of checking EISA/ISA ints. It turns
out the FreeBSD code did the right thing by starting EISA/ISA vectors
at 0x800.

d55ab6af0d EISA/ISA memory space is any pa < 8MB. 2000-05-07 05:31:39 +00:00

34255ec554 Add in a first pass at Alpha 4100 (Rawhide) support. It doesn't quite
boot all the way yet, but it's darn close (blows up somewhere probing
the PS/2 mouse on the EISA bus).
