jonathan 428a2b873f Fix polled I/O getc/putc functions for non-serial consoles when
still cold (e.g., to initialize keyboards and mice).
Why these use polled, rather than interrupt-driven, IO is a mystery.

jonathan 23ad284399 Remove obsolete `#include <machine/MachConst.h>'.
Where CACHED_TO_HYS() is still needed for kernel-virtual-to-physical
or physical-to-uncached mapping (fb drivers), replace with
`#include <mips/cpuregs.h>'.

jonathan e1a0a7fc77 Split dcparam() into two parts:
* dcparam() with normal tty t_param interface, which calls
    * cold_dcparam() called with explicit dc7085 register address
      and flags, which does the work and is also callable when cold,
      to set up console (or kgdb) line parameters.

christos d286889901 backout previous kprintf change 1996-10-13 03:39:27 +00:00
jonathan 99a94f057e Put back the ttstop-returns-void changes accidentally clobbered by
merging the 1.2 and -current branch serial-console fixes.

jonathan 874baa6c95 Rewrite dc7085 (dz-11 clone) driver as MI back-end, with bus-specific
cfattach front-end code:
  dc_ds for the decstation 2100( pmin), 3100 (pmax), and 5100.
  dc_ioasic for the decstation 5000/200 (3max) which does  not have a
  DEC TC-style IOCTL asic, but is configured as if it did.

* Add pre-autoconfig  code initialization of kerenl dc driver console I/O
  for remote serial consoles.  The hack to use PROM serial I/O until the
  dc device is autoconfigured is no longer necessary.

jonathan ad20e52d11 Commit snapshot of reworked dc driver to trunk, to pull up fix for
serial consoles to the 1.2 branch.  Includes:
  * dynamically allocated new-config softc
  * remove dependencies on Decstation CPU type, use flags in softc instead.
  * pass in values for softc flags (q.v.) from parent-specific attach code
  * #ifdef out rts/cts flow control support until it's known to work on
    200s.
  * redo initialization of serial consoles (needs more work).

jonathan 2bc8c4e5c2 Merge in 4.4BSD-Lite -> 4.4BSD-Lite2 changes. (untested).
The Lite2 changes  include:
  * Remove the last vestiges of high-bit-set-means-delay for output chars.
  * Handle the  2100/3100 having partial modem control on line 2 only,
    whereas the 5000/200 has modem control signals on lines 2 and 3.
  * Add RTS/CTS support for lines 2 and 3 on a 5000/200.
  * Add more s = spltty(); splx(s); where needed but not present.

mycroft b3eac79b64 tty stop functions really should return void, not int, and certainly not both. 1996-09-02 06:43:16 +00:00
mhitch 40c440b66e Do tty_attach() for serial lines and MAXINE console. 1996-06-16 16:50:56 +00:00
jonathan 465d53bd4d Fix sense of strcmp() comparison that broke dcmatch() on real ioctl asic hw. 1996-06-13 22:43:33 +00:00
jonathan 7adf57b6f5 Fix the reworked autoconfiguration to also boot on a 5000/200.
Check and avoid trying to configure (or dereference unknown arguments
to dcattach() and dcmatch() when called with busses the driver doesn't support.
1996-06-13 08:06:12 +00:00
mhitch de1b9b4230 Fix autoconfiguration stuff to match the alpha. The DS3100 will now
configure properly.  Also fix devices with TurboChannel and mainbus
attachments so they will work if no TurboChannel was configured.
Fix a panic when the dtop keyboard handler receieves a character
before the device has been opened.

jonathan 50dd608c3b more cleanups for -Wall:

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.

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.

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.

jonathan 88b9b7eb4a Update DECstation drivers to use new-style config, removing
old-style config support, except for SCSI disks and tapes.
1995-08-10 04:21:35 +00:00
jonathan 1bacfdc2dd Add preliminary support for new-style configuration: struct cfdriver,
and match and attach code.  Still use the static softc so that drivers
work with kernels configured with either new or old config.
