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.

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...)

thorpej 56fed0c102 Fix slight oversight in previous change. 1996-04-07 05:50:59 +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.)

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).

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).

pk 8eeab3102b Probe clock registers on sun4s to make sure we attach the correct device
(sun4m has clocks at obio too).

pk 8e427a346f Check for frame pointers we can handle (i.e. in kernel space). This prevents
data faults when tracing proc0's context.

pk b0fd2dabcb Include fd.c if (fdc | fd), so we're not obliged to define a device
at fdc.
1996-04-04 22:57:55 +00:00
cgd 83f9bdc359 update for the fact that config_found() and config_rootfound() now
return pointers.  (Check vs. NULL, rather than just boolean tests.)

pk cf4009e56c Include support for sun4m timers and counters: hardware register layout
has changed. There is a counter for each CPU (currently, just one supported).
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.

pk 3c89c0901d Aaron's SRMMU/sun4m pmap implementation.
Note: multi-architecture kernels use function pointers for several PMAP

macros (see machine/param.h) wherever possible.
