simonb dc1d3940db Nuke register and remove trailling white space. 1999-04-24 08:01:01 +00:00
mrg ad52a7fe49 make this compile again with no rcons. 1999-04-20 06:42:54 +00:00
pk b13e5d1469 Quote "AS IS" as in the majority of Carnegy Mellon notices. 1999-04-12 20:38:17 +00:00
pk c40eb1cd97 Fix a pasto in copyright text which has been procreating like rabbits.. 1999-04-06 20:09:18 +00:00
ad 3ce634a350 Added support for cursor keys, function keys and friends. kbdMapChar now
returns 'char *' to do this. Codes returned for the various keys match
what 'rcons' termcap entry expects.

kleink 15afeeecca Remove an incorrect (but harmless) comment. 1999-01-29 08:42:27 +00:00
jonathan 9c2700d2b8 Jason Thorpe's changes from PR#6848. Makes 115200 bps work on some systems.
Reverse sense of #ifdef to disable 76.8k and 115.2k until we can verify
it works on all 8530 chips (similar changes didnt work on a /240 in 1996).

jonathan 03b30a046d * make scc_tty_init() callable when very cold: call scc_coldparam() directly.
Use scc_tty_init() in scc_consinit().  Declare scc_consinit() in sccvar.h.

* Remove last vestige of special-case console handling in sccparam() code.

* Call scc_consinit() from findcons scc_serial() console-setup.
  Dont PROM for scc serial console at all.

jonathan ba531b48c6 Use console_debugger() hook to enter DDB. 1998-10-29 21:25:17 +00:00
mhitch 2c412f42bb scc_softCAR is a bit array, so set it accordingly for a serial console
port (instead of using the scc line number).

jonathan e7312dce1d * Mouse reset blocks waiting for response for mouse.
Only initialize the mouse if we are using rcons as the console device.
1998-03-30 02:15:37 +00:00
jonathan 1c0730217a Rewrite pmax console-probing code from scratch
as pmax/dev/findcons.c:
 *  Follow the same logic: look for the device the PROM is using.
 *  If it's a framebuffer and we don't have a driver for it, try other
 *  framebuffers in PROM search order.
 *  If no match found, warn user and fall over to serial console.
 *  if no serial console found, go back to PROM.

Rework tc/scc.c attach routine to give cleaner initialization semantics.
Prune out old 'braindamage' code.

jonathan 6d836436ac Commit snapshot of pmax console rework as basepoint for 1.3.2 pullup:
* Do rcons output properly, using cn_tab->cn_dev which points
   at rcons cdevsw entrypoints.

 * The pmadx console code was using keyboard (serial) device
   (major,minor) for raster consoles with special code in the keyboard
   drivers to catch output intended for consoles, pull it off the device
   queue, and print them via cnputc().
   Ifdef out  RCONS_BRAINDAMAGE.

* Other minor cleanup to pmax scc driver.

jonathan 5cfab7fb5b Whitespace, cosmetic changes against alpha/tc/scc.c 1.40. 1998-03-22 07:15:20 +00:00
jonathan 6e3073d769 More tty dialin/dialout changes (t_wopen).
NB: dtop is a keyboard/mouse bus and doesn't support dialout.
1998-03-22 07:04:13 +00:00
jonathan 580a0a4d12 Add local `extern' declaration of ioasic_cd, as in alpha/tc/scc.c.
Missed here after the removal of  ioasic_cd decl from ioasicvar.h.

thorpej 0475e09198 Update for changes to config. 1998-01-12 20:04:24 +00:00
jonathan a5449ca17c Back out read-side DELAY() in previous revision added on advice of
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.
1997-11-14 01:38:57 +00:00
jonathan 0f41aef4b9 Workaround for port-pmax/4438 (pmax kernel glass-tty console code is broken)
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.

jonathan d1ec048977 DDB for mips.
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.
1997-07-07 03:54:24 +00:00
jonathan 1f44934407 * Change Sprite MACH_xxx prefix to MIPS_xxx.
* Use standard mips terminology (xxx_KSEG0, xxx_KSEG1) instead of the
  (more meaningful) Sprite names (xxx_CACHED, xxx_UNCACHED).

1997-04-26 02:26:54 +00:00
jonathan f5343d2229 Cleanups, and convergence with the Alpha driver:
* 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.

mhitch b7ef581afb The MAXINE serial console is on scc0 (the only SCC on the MAXINE) instead
of scc1.  Fix the check of which scc to initialize the console serial line
so that the MAXINE serial console will work.

mycroft b3eac79b64 tty stop functions really should return void, not int, and certainly not both. 1996-09-02 06:43:16 +00:00
mhitch 56a2e98b80 Do tty_attach() for serial lines. 1996-06-16 16:49:07 +00:00
mhitch fe55416706 Fix autoconfiguration stuff to more closely match the alpha - primarily
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.

jonathan f7af868d1f Additional fixes to complete the NetBSD/1.1B config changes:
change IOASIC cfdriver references  from "ioasiccd" to "ioasic_cd"
1996-03-17 22:20:08 +00:00
thorpej 77abd102b7 New device attachment scheme:
- 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.
1996-03-17 01:38:52 +00:00
jonathan b5c68cb4cd Add serial-console support that works with `new-style' (config.new) autconf
code.  Substantially the same code tested on a 5k/240. Should work on a
5k/1xx.  Not tested on a  MAXINE, where the single unit may break the
PROM-channel-number to driver-channel-number mapping.

jonathan e229c8d175 Resolve pmax and alpha IOCTL asic driver differences, pass 1:
Rename the ioctl asic register and slot macros from ASIC_<xxx> to
IOASIC_<xxx>, to be compatible with the machine-indpendent names in
sys/dev/tc/ioasicvar.h.  The pmax code still uses
sys/arch/pmax/pmax/asic.h, as some of the registers and offsets
defined there are not yet defined in sys/dev/tc/ioasicvar.h.

Rename the ioctl asic base-address pointer from `asic_base' to `ioasic_base'.
1996-01-31 08:46:42 +00:00
jonathan 5ea2ec2357 Re-write Decstation turbochannel autoconfiguration code to use the machine-
independent TC support in sys/dev/tc/tc.c and sys/dev/tc/tcvar.h:
  * Change the tc autoconfiguration tables to use a struct tc_attach_args
    instead of the ad-hoc structure.
  * Change all pmax device drivers to use a `struct confargs' that's
    assignment-compatible with  sys/dev/tc/tcvar.h `struct tcdev_attach_args'.
    Devices that can be present on a TC or as ioctl asic/mainbus builtins
    use  the same `struct confargs'.
  * Eliminate the `BUS_CVTADDR()' macros which the pmax port inherited from
    an old, now-obsolete sys/arch/alpha snapshot.

  * Update the comments and debugging code in interrupt handlers to
    be consistent with the machine-independent TC support.

Other commits that overlap the same source files include: re-enabling
clock-tick interrupts earlier, and counting hardclock ticks for vmstat -i.
1996-01-29 22:52:15 +00:00
jonathan 8945da0c58 Add speed entries for 7200 and multiples.
Add as-yet-unused speed entries for a 1x SCC clock, up to 200 Kbits.

Remove old top-bit-means-delay code, since nothing seems to need it,
and it apparently partially broke lk-201 initialization anyway.
1995-09-29 21:55:19 +00:00
jonathan f28ebc66ca Fix SCC bug that broke getty on pmax SCC lines: if RAW and LITOUT were
both off, haracters with their top bit clear were interpreted as a delay.
This (strange) behaviour is still available if  SCC_PARITY_MEANS_DELAY
is defined.
1995-09-25 22:10:56 +00:00
jonathan 27361456c5 Force a delay after calling SCC_WRITE_DATA() to give the chip
registers time to settle. DELAY(2) is reportedly enough.  Without the
delay, output characters are occasionally doubled.
1995-09-25 04:30:43 +00:00
jonathan f8fbfa0ce8 Change pmax rcons and low-level serial drivers to support the
old-style pmax polled input for cn_getc(). Needed because the
input side of rcons is not initialized in time for GENERIC kernels
to use it to read a root/swap devicename from /dev/console.
