thorpej ac9df157aa 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.

naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.

abrown 6b768c677a Now that we have lehwinit() for the Sun4m, make sure that we wait 20ms 
after changing the cable type, as specified in the chip documentation.
Also, sanity-check that sc_dma is valid in case a Sun4m ever exists without
a ledma.

to support selecting UTP media on sun4m
 1996-04-22 02:37:10 +00:00
abrown 709298a10a - Changed Sun4m DMA chip support to detect and use maximum available SBus 
burst size when transferring data.
- Changed ledma attach code to pay attention to the PROM's notion of what
  cable type is being used. Note that this patch does not fix the problem
  recently discussed on port-sparc; in most cases the PROM doesn't know
  what cable type is being used. The default is now TP rather than AUI,
  though. A complete fix is forthcoming.
 1996-04-22 02:34:53 +00:00
cgd d7d306aeb7 change LANCE copy & zero functions' names to start with amd7990_, and 
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).

pk e4394459a1 `bootdv' is gone. Instead, set the device pointer in the `struct bootpath' 
that is passed in the attach arguments.
 1996-04-10 20:46:05 +00:00
pk c28fcc3539 Use extra value in `struct bootpath' to describe the PROM's bootpath better. 
Use the bootpath[] array in setroot() to determine partition info in case
of boot devices of type DV_DISK. Also, precook more SCSI device info in
fake_bootpath() to simplify dk_establish().
 1996-04-10 20:40:14 +00:00
pk 5f2d466997 Make room for another `value' in struct bootpath. Drop the global `bootdv' 
in favour of storing the device pointer in the bootpath[] element corresponding
to the boot device. This also allows the opportunity to get to "intermediate"
devices (e.g. busses) should the need for this ever arise.

thorpej 940ccbc5df Fix typo that caused sun4 machines to be misidentified as sun4c-class. 
Fixes reported problem of binstall not stripping the a.out header from
the boot block on sun4 machines.
 1996-04-07 20:00:12 +00:00
thorpej 77366064b8 Fix oversight in sun4m changes: the CPU attach code moved, so the CPU 
was never getting attached on a sun4 machine.  Fix this so that the
cache and FPU get enabled on sun4 machines.  (Believe me, a 4/260 is
slot enough, *with* the cache...)
 1996-04-07 06:02:20 +00:00

thorpej d68e57ee64 Make this compile again on a SUN4-only kernel. (Avoid "unused foo" 
warnings from gcc -Wall.  While the optimizer is smart enough to
eliminate dead code, it looks like the rest of gcc doesn't Get It.)
 1996-04-07 04:48:46 +00:00
chuck e50fc72424 make netbsd/sparc boot on sun4 once again. the sun4m changes introduced 
config lines for obio0 devices without addresses (thus cf->cf_loc[0] took
the default value of -1).   we now ignore these entries on a sun4 since
they could never be valid (eliminates a 'panic:alignment' fault at bootup).
 1996-04-05 21:50:05 +00:00
chuck a7c600676f make netbsd/sparc boot on sun4 once again. the sun4m changes introduced 
config lines for obio0 devices without addresses (thus cf->cf_loc[0] took
the default value of -1).   this caused autoconf.c to map memreg0 to
obio physical address -1 (invalid).   as soon as we took a memory fault
the code in memfault_sun4 [locore] would get a Watchdog timeout when trying to
read memreg0 (a.k.a. par_err_reg).

 1996-03-31 23:24:59 +00:00
pk 8de1fd22bc Add sun4m support. Many, many changes.. 
Note on multi-architecture kernels: most architecture dependent traps are
forked off directly by having a separate trap table for each (sun4,sun4c,sun4m)
This reduces the number of tests on `cputyp' significantly, and it's easier
on the mind. There are still some entry points that need to test `cputyp',
most notably microtime().. yuck.

    - kgdb_copy called with only two arguments.

Fix conf.c so that it used the _conf.h files from other places instead of
rolling its own.

chuck 9bb0e5dba5 Fix two bugs reported by Don Koch <aardvark@poirot.krl.com> (PR#2169) 
[these bugs apply to the xy as well as the xd driver]
 [1] check return value from malloc() for NULL before trying to bzero it.
 [2] use "=" rather than "|=" when writing to CSR (otherwise you may
        ACK something you don't mean to!).

thorpej edf9d66f32 First-cut support for P4 framebuffers. Currently supports P4 variants 
of bwtwo, cgfour, cgsix, and cgeight.  Includes support for attaching
the overlay plane of the cgfour and cgeight as a bwtwo instance (a'la
SunOS).

P4 register descriptions, cgfour driver, and cgeight driver partially
derived from OpenBSD.

This code may still need polishing.
