18a1481f7a Use NFS_BOOT_DHCP rather than NFS_BOOT_BOOTP. The former is more 
flexible, and the boot blocks use DHCP already(!!!) and it'd be good

faf1155de5 Revamp pv_table management: 
- Make pv_table an array of struct pv_head's, which contain LIST_HEADs
  for the pv_entry's, as well as page attributes (mod, ref, ptpage).
- Use <sys/queue.h> to manipulate pv_entry lists.
- Fix several obvious bugs in pmap_collect_pv().
- Use K0SEG to access pv_page's.

f17bbcfffa Changes necessitated by the fact that all pmaps have their own level 1 
page tables: use curpcb to determine which level 1 map defines the
current VM context, and use that level 1 map when mapping and unmapping
the PROM.

c4e7c88520 Step 1 of the Grand Alpha Pmap Rototill: 
- Clean up pmap_bootstrap() some, and make a slight change to how the
  PROM mappings are saved.
- Give each pmap its own level 1 page table, rather than sharing a global
  level 1 page table.  This will eventually allow for Very Large user
  address spaces.
- Keep a list of all pmaps, so that when kernel level 2 page tables are
  allocated, all level 1 tables may be updated.
- Add a couple of functions for allocating and freeing page table pages.
- Add a few comments about ASN allocation.

5d56ce57ba Several changes related to all pmaps having their own level 1 
page table:
- Update the current hwpcb pointer in the SWITCH_CONTEXT macro, so that
  we know it's always correct.
- Optimize cpu_switch(): if we're switching to ourselves, skip the
  actual context swap.
- Clean up some comments and remove some code rendered obsolete by
  the fact that address spaces are now selected by switching to a
  new level 1 page table.

25d056473c Clean up kernel initialization. Use the bootinfo structure (or innate 
knowledge) earlier, and gather all information needed earlier.  Mark the
init code carefully re: when it can print stuff out, when it can expect
the firmware to stop working, etc.  Be more careful about using the PROM
console and other PROM facilities, and hint that in the future all use
of firmware/boot program callbacks by the kernel should go away (since
the world may not be mapped the way the firmware/boot program wants!).

(filling them in if the boot blocks didn't pass them), and make versioning
a small bit more sane.

e62d894d7a Implement a prefetch spill page for SGMAP DMA. This works around a slight 
annoyance on systems that prefetch the next page during memory -> device
DMA if the DMA comes within a certain distance of the end of the current

would not have the valid bit set.

makes DMA much faster...)

- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
  supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
  by the way it's used).

The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.)  The __indr_reference
change was made for consistency.

* support chip clocks != COM_FREQ, by introducing sc_frequency (for the

  parameter to comcnattach() and com_kgdb_attach().

- Make i386/machdep.c and alpha/dec_xxx.c call com*attach() with the freq.
  parameter.
* supio_attach_args get two more fields: a sc_ipl and a sc_arg, both ints.
- com_supio uses the first for interupt establishment (all childs will, as
  soon as they exist) and the 2nd for sc_frequency.
- drsupio passes sc_ipl alway as 5, and for the "com"s, sc_arg as 16*115200

d1fbc82e28 From page 6-9 of "Alpha AXP Architecture Reference Manual, Second Edition": 
An IMB intruction must be executed after software or I/O devices
	write into the instruction stream or modify the instruction
	stream virtual address mapping, and before the new value is
	fetched as an instruction.

We were missing calls to IMB after mappings were changed, which caused
systems with large I-caches (e.g. my AlphaStation 500) to fail miserably
when mapping in new pages of program text, or when context switching
(I couldn't even get the shell from init!).

it after accessing configuration space), not just eb164's.

again, I made an error that caused this to not be used on eb164 systems,
either.  Thanks to Matt Jacob for pointing out this goof.

998d79d26a Add support for DDB (in-kernel debugger) to NetBSD/alpha, based on 
such code for Mach 3's Alpha port.  Initially reworked for NetBSD/alpha
by Chris Demetriou, and then heavily hacked on by me.  Works, but is still
a little rough around the edges.  Known problems:

- Error recovery could be improved a bit.
- Back traces don't work.
- Single-stepping can be flaky, at times.  (Alpha doesn't have hardware
  support for single-stepping, and I'm not entirely convinced the
  MI DDB software-emulated single-stepping logic is 100% correct.)
- Logic for when to drop into DDB needs some improvement.

28b1691f4d when i was documenting the bus_space interfaces (the document 
was sent to developers, but will eventually become a man page or
something), i noticed a few in various names:
(1) _map and _alloc should take a flags argument, rather than a
    'cacheable' boolean.
(2) BUS_BARRIER_* flags should be BUS_SPACE_BARRIER_*.
(3) bus_space_copy_* should be bus_space_copy_region_* for consistency
    with other region ops.
Fix all of these (in a backward-compatible way, at least for now).  Redefine
internal usees of those names to use the new names.  Also, while at it,
clean up the copy functions (remove unnecessary variables) and make sure
that they and other functions conform to the spec.
