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).

nisimura a3d9c9bd87 - Clearify what ioasic_init() is for. No runtime difference because
NetBSD/pmax does not fully utilize the hardware features.

jonathan bdf3cb0884 * Fix typo in ROM name of mfb (PMAG-AA)
* Use TC_ROM_LLEN instead of constant, add space for sentinel.
* Don't print fb dimensions at console-probe time.

jonathan c7597ae8b8 Rework, based loosely on suggestions from Tohru Nisimura.. 1998-04-19 10:18:20 +00:00
jonathan 9caaf18836 Rework pmax turbochannel config, as suggested by Jason Thorpe.
Also make TC framebuffer-console search table-driven.

Does not yet include "tcasic" layer; there's no such hardware on DECstations
and nothing for a tcasic layer to do.

jonathan e487483678 oops, diffs to use dev/dec/mcclock_pad32 were in a different tree. Fix. 1998-04-19 07:54:45 +00:00
jonathan c84f4e94d9 Copy alpha/tc/mcclock_ioasic.c (duplicated in pmax/tc/mcclock_ioasic.c)
into sys/dev/dec and split into a clockfns layer and a "middle" layer
for other DEC systems which use mcclocks with each onchip byte
register padded out to a 32-bit word.

Clone alpha/alpha/mcclock (also duplicated in pmax port) into
sys/dev/dec, and ifdef for default clockrates on pmax and alpha.

Use new machinery on pmax for ibus,ioasic attached mcclocks.

jonathan ba4e7c74a9 Remove ancient non-MI pmax/tc/tc.c code. 1998-03-30 10:41:34 +00:00
mrg ca86fc945e <pmax/pmax/trap.h> has been obsoleted... 1998-03-30 04:45:50 +00:00
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
thorpej 8a86fd47be It's Just Wrong to configure a KN02 system slot as an IOCTL ASIC, but
since it's currently done that way, nuke the gratuitous printf that
reports the behavior.
1998-03-26 06:35:27 +00:00
jonathan 383ff0cb59 * Use new defopt model-specific options and opt files.
Replace all DS5000_* and DS3100 ifdefs with ifdefs on DEC_ options.
* Use MI declarations, not pmax-specific, in model-specific init
  that uses baseboard (ioasic) registers.
* Further cleanup of machdep.c.  Clock-tick still needs more thought.
* Use 'ibus' names for 3100 baseboard devices in MI code.
1998-03-25 06:22:19 +00:00
jonathan 6975dc93a9 Split sys/arch/pmaxpmax/{machdep.c,trap.c} as suggested by Jason Thorpe:
* add "Platform" support inpmax/pmax/sysconf.c and pmax/include/sysconf.h
   (based on Alpha cpuconf.[ch], with a namechange to avoid clashes with
   support for  models of MIPS cpus. They  differ more than Alphas).

 * For each supported model of DECstation, create a separate file
   with the support for that model.  Use model codenames, since
   support is really baseboard-specific and CPU daugherboards can change.
   Move code from machdep.c and pmax_trap.c,
   Add sysconf (nee "cpuconf") support.

 * Rename model-specific functions to match sysconf names.

 * Clean up autoconf.c.  Use platform callbacks.

 * Retire pmax_trap.c.

Leaves  I/O bus configuration and console configuration untouched.
1998-03-25 03:57:53 +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.
1998-03-24 08:39:02 +00:00
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.

jonathan 580a0a4d12 Add local `extern' declaration of ioasic_cd, as in alpha/tc/scc.c.

perry 015e898c02 RCSID Police. 1998-01-05 07:02:46 +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.

Partly merged back with Alpha code by Jonathan Stone. Needs more merging.

jonathan 1f44934407 * Change Sprite MACH_xxx prefix to MIPS_xxx.
* Use standard mips terminology (xxx_KSEG0, xxx_KSEG1) instead of the
