tech-kern. Reported by Sean Davidson to cause erroneous doubling of
keyboard input on a 5000/50 under load.
Increasing the DELAY() from 2 to 30 doesn't help. Remove it for the
1.3 release. May cause problems with low-speed serial input, but
console keyboards work properly.
until a proper fix is available:
Perpetuate the 4.4bsd design even further. Change keyboard-driver
open routines to check for an active raster console. If active, set the
keyboard struct tty's t_winsize from the rcons t_winsize on first open.
See pr 4438 for remaining problems and discussion of a complete fix.
Add DDB interface to /sys/arch/mips/mips..
Rework heuristic stack traceback to work with DDB.
Add hooks to print exception log from DDB.
Add hooks from pmax console drivers: call Debugger()
after break from serial console, or 'DO' key from LK-xxx.

Also gc usused references to NSCC and #include "scc.h"
* kill scc_tty[] and needs-count.
* Add usable-when-cold version of sccparam().
* Add pre-autconf() console initialization entrypoint.
* remove lint for gcc -Wall
* wbflush() -> tc_mb()
all but the last of which have been fed through cgd and committed to the
Alpha scc driver.

a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
* Add interrupt handler for 3MIN, where we cannot disable TC slot interrupts.
* Change mfbinit() signature to match other (pmax) TC framebuffer init
routines.
* TODO after 1.2: add {cfb,mbf,sfb}var.h. Declare init functions there.
* Eliminate the #ifdef DS5000 and kernel config option DS5000 altogether.
option DS5000 was a hangover from 4.4bsd/pmax; it's never been clear
if it means "support for DS5000/200" or "support for any TC machine".
This implictly fixes pr 1828.
* Use the "tc.h" and NTC generated by config for a "tc? at mainbus"
where appropriate, intsead of #ifdef DS5000.
* Canonicalize the spelling of kernel options that enable support
for particular models. Use
DS5000_25 for the Personal Decstation aka MAXINE aka KN02-ca
DS5000_100 for the 5000/1xx series aka KMIN aka KN02-ba
DS5000_200 for the 5000/200 aka 3MAX aka KN02
DS500_240 for the 5000/240 aka 3MAXPLUS aka KN03
and change DS_5000_xxx to DS5000_xxx everywhere.
* Wrap the interrupt handlers for each model in the appropriate #ifdef,
instead of wrapping all of them with "#ifdef DS5000".
* Wrap the TC autoconfig for each model in the appropriate #ifdef.
the IOASIC attached devices. The DS3100 will now configure properly.
Fix the DS5000/25 IOASIC table entry for the RTC so the RTC interrupts
get enabled.
Fix up a moved include file.
naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.
Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.
remove their 'integrate' (usually defined to be 'static') keywords.
when lance drivers are split up by attachment, more than one file will
reference the copy/zero functions (i.e. not just the file that pulls in
am7990.c... and eventually inclusion of am7990.c should go away entirely).
Add new device-attach struct cfattach le_tc_ca and struct cfdriver le_cd.
Change IOASIC cfdriver references from "ioasiccd" to "ioasic_cd".
Change "mainbuscd" to "mainbus_cd"
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
works with the revamped machine-independent TC code in sys/dev/tc.
A name change is necessary to avoid a name clash with sys/dev/tc/tc.c,
which also creates a tc.o.
