pk 4c26e95dde Initialize relevant elements of the `romaux' structure in romprop(). 1996-04-09 15:24:00 +00:00
pk 1a1a8ba8c9 Undo unintended change in previous commit: _mcount is static. 1996-04-08 20:55:36 +00:00
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...)

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).
 1996-04-05 21:44:25 +00:00
pk 8eeab3102b Probe clock registers on sun4s to make sure we attach the correct device 
(sun4m has clocks at obio too).
 1996-04-04 23:55:47 +00:00
pk 8e427a346f Check for frame pointers we can handle (i.e. in kernel space). This prevents 
data faults when tracing proc0's context.
 1996-04-04 23:25:35 +00:00
abrown 1372d856d7 cpu.c: correctly identify Sun4m associative caches 
kgdb_stub.c: make it compile again with Sun4m-only kernel
 1996-04-04 23:06:32 +00:00
abrown 1068aa5751 Add back support for cached DVMA on SuperSPARC (sun4m) machines that was lost 
during merge
 1996-04-04 23:05:22 +00:00
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.)
 1996-04-04 06:25:00 +00:00
cgd 7bc2baeb01 update for the fact that 'alldevs' is now a TAILQ. 1996-04-04 00:27:24 +00:00
pk 7311f0da23 Late-breaking patch from Aaron. 1996-04-01 21:09:39 +00:00
christos 10ffa5da40 Fix warnings when SUN4M is not defined. 1996-04-01 19:16:41 +00:00
christos 3dbbc8d3e9 Fix another printf format argument. 1996-04-01 17:37:08 +00:00
christos 4bdb6550cb Added missing prototypes and include files, fixed parentheses so that it 
compiles cleanly.
 1996-04-01 17:36:20 +00:00
christos 362a6875bf Remove last dependency to dev_conf.h and the file itself. 1996-04-01 17:34:34 +00:00
christos f34addbb3b - remove dependency to dev_conf.h 
- remove unneeded casts for %b
 1996-04-01 17:33:10 +00:00
christos 34f644d1b9 Remove casts of printf args for %b format. 1996-04-01 17:31:38 +00:00

pk 25b6ab86fe Update device list. 1996-04-01 00:20:31 +00:00
pk 3cf5ed1f30 Various cleanup; mostly trailing spaces/tabs. 1996-03-31 23:44:53 +00:00
pk 8347d3f584 The sun4m name for this device is "auxio". 1996-03-31 23:43:21 +00:00
pk 301e978cf8 Various sun4m-related changes straight from Aaron. 1996-03-31 23:38:29 +00:00
pk e0344005b4 Changes to match 4m-aware locore.s. Note changed `trapbase' and 
`sparc_interrupt_{44c.4m}' labels.
 1996-03-31 23:35:20 +00:00
pk e743dda2a9 Update for 4m locore.s. Remove some items, since locore.s now #includes 
param.h
 1996-03-31 23:28:03 +00:00
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.
 1996-03-31 23:19:22 +00:00
pk 6d76616bf0 The sun4m IOMMU "device". 1996-03-31 23:09:32 +00:00
pk 7b55c61c27 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 23:07:59 +00:00
pk df2a68f25b Add sun4m VA definitions (for clock and interrupt). 
Make these generic for all architectures (i.e. avoid `#if defined(SUN4*)'s).
 1996-03-31 23:03:31 +00:00
pk ff109a19a3 Accomodate sun4m CPUs and caches (Aaron). Cache handling needs to be 
revised.
 1996-03-31 23:00:40 +00:00
pk df08150880 Updates for sun4m. 1996-03-31 22:57:09 +00:00
pk 35802bf06b Accomodate sun4m device layout (v3 PROM) and special 4m startup goo. 
Heavily cleaned from most `#if defined(SUN4*)' stuff in favour of
CPU_ISSUN4* macros.
 1996-03-31 22:55:33 +00:00
pk 678fbb4806 sun4m device definitions and bus structure. 1996-03-31 22:52:38 +00:00
pk b2d12c182b Aaron's sun4m-related trap handling (memory faults). 
Note that fork() no longer return in syscall() in the child.

Add a couple of `#ifdef DEBUG's.
 1996-03-31 22:51:58 +00:00
pk d15de4b09b Initialize DMA addresses properlier in cpu_startup(). 
dumpsys(): do not try to dump first physical page, this fucks up pmap_extract().
 1996-03-31 22:48:24 +00:00
pk 3c89c0901d Aaron's SRMMU/sun4m pmap implementation. 
Note: multi-architecture kernels use function pointers for several PMAP
entry points.

Cut down the `#if defined(SUN4*)' mess severely by using CPU_ISSUN4*
macros (see machine/param.h) wherever possible.
 1996-03-31 22:42:59 +00:00
pk 2f3ec93250 Various cleanup; mostly trailing spaces/tabs. 1996-03-31 22:38:29 +00:00

pk 954302ae70 Handle sun4m `ledma' and `espdma'. 
DMA setup requires services of the IOMMU.
 1996-03-31 22:32:45 +00:00

pk 25aa56ae29 Handle sun4m `obio' devices. 
Cleanup `#if defined(SUN4*)' mess.
 1996-03-31 22:28:38 +00:00
pk 96f175d477 Add sbus_translate() to deal with slot address translations, including 
new v3 PROM style "range" properties. This routine is also called from obio.c
(which can be viewed upon as just a another Sbus slot).
 1996-03-31 22:27:15 +00:00
pk 345295ff08 Deal with sun4m le/ledma. Work around spurious interrupt problem (aaron). 1996-03-31 22:22:52 +00:00

at the moment.
