pk 383448522d Refer to KERNBASE instead of its current numerical value in comments
and some early debugging code.

pk a3140bf9f2 NetBSD 1.2 and earlier sparc bootblocks have KERNBASE compiled in. This
prevents booting DDB kernels that are built with a different value of KERNBASE.

Apply a correction based on the magic number passed in by the bootblocks.

New bootblocks without the hard-coded KERNBASE reference will be assigned
a new magic number.

pk c635b25325 In kbdattach() (the pseudo-device attach routine) wait for the keyboard
reset sequence to complete.  Just sending the reset command and rushing
off -- like it used to do -- might cause the keyboard's response to get
lost in case the remaining kernel initialization decides to interact
with the console (RB_ASK!) by calling cngetc(), which goes off polling
within the PROM.

thorpej 9a5f8236b5 Don't panic if we receive a Processor Correctable Error or a System
Correctable Error; report them, instead.

XXX Need a platform-specific machine check handler so we can decode the
logout area on such errors.

thorpej 12b0c2a20a The Alpha console uses BOOTP for network booting, so the NetBSD kernel
should, too.  Enable the BOOTP support in nfs_boot().

thorpej f784e8dc15 Apparently, new AlphaStation 500/600 firmware has the same problem with
PCI master aborts as eb164 firmware, so use the same workaround mechanism
on all system types (clear error register's master abort bit, and check
it after accessing configuration space), not just eb164's.

This also fixes a bug on eb164's - when making the Alpha port compile
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.

setting up and enabling the MMU.  This has the effect of ensuring
that any stray interrupts that get posted before the IPL is lowered
will be handled gracefully, i.e. without an access fault or illegal
instruction exception.

thorpej ed2ec4869c Update for Chris Demetriou's changes made to the bus.h interface:

- "cacheable" argument becomes a "flags" argument instead, with
  BUS_SPACE_MAP_CACHEABLE and BUS_SPACE_MAP_LINEAR flags currently
  defined.

thorpej 9dcf694bd2 Prototype db_register_value(). 1997-09-06 02:02:25 +00:00
thorpej 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.

* cflush - Cache Flush
* rdval - Read System Value
* wripir - Write Interprocessor Interrupt Request
* wrval - Write System Value

cflush, rdval, wripir, and wrval are used in multi-processor environments.

scottr 7883fba4bf Two video-related changes:
