cgd 2a9a4b6fde fix slight bogons in splhigh() usage, that were introduced when the 
behaviour of splhigh() was changed.  The new behaviour raised the level to
IPL_HIGH if it was lower, but left it alone if the same or higher.  Apparently
the firmware transfers to NetBSD with all interrupts blocked, or something
else blocks all interrupts (including machine checks) before the code
is really started.  This meant that machine checks were blocked during
device probes, leading to false device probes _and_ an unexpected (and
therefore fatal) machine check at the spl0() after autoconfiguration.

thorpej 4f5d0d3849 Split DEC 3000/300 and 3000/500 DMA functions into separate files, 
suggested by Chris Demetriou <cgd@netbsd.org>.

is 7b1633fee3 Make fpfault() faster if 68020/30 only, and the code smaller if 68040/60-only. 1997-06-05 20:57:13 +00:00

leo f796b57669 * finalize 060 stuff. 
For locore.s also nuke cacheop-functions now provided in m68k.

leo 327cf04b4b Implement and use splraise(). 1997-06-05 19:38:16 +00:00
cgd 891e8db771 two more slight bogons 1997-06-05 17:36:26 +00:00
cgd 1c33c6bff8 actually, declare _splraise() as an inline function, because: 
(1) it was using 'max', and some functions use a variable
	    of that name (*sigh*), and
	(2) that makes it easier to be a bit trickier, and only call
	    swpipl if changing the IPL.

cgd 100dbb8a3c parens around macro arg (this is an old one) 1997-06-05 17:20:17 +00:00
cgd 57c012e265 make sure that splnet(), splbio(), splimp(), spltty(), splclock(), 
splstatclock(), and splhigh() all _raise_ the IPL.  (splhigh() is _not_
the highest possible IPL; mcheck is...)

is 6d6e724440 Reorganize buserr/addrerr stuff, to allow omitting unused code in single-cpu 
kernels, at the same time getting rid of up to 3 conditional branches and a
bit over one cacheline fetch (for the 68060; the saving is a bit smaller for
040 and yet smaller for the 020/30).
While we're here, also get rid of an redundant lea (using SP-relative
addressing) and of two redundant pushes.
While we're here, also fix a panic which would tear us down on 68060 machines
if a branch prediction error ever occured.

jtk d935ace5a0 1) When we cannot complete our attachment, don't just return 0 but also 
disconnect from the BIOS

2) when text segment as claimed by BIOS is out of sensible range, punt
completely rather than trying to shrink it to fit the ISA hole.  Some
BIOSes would crash with the previous behavior.  Some won't have a
working APM with the new behavior, but their BIOSes are broken.

Suggested by Chris Demetriou, with very minor tweaks by me.

cgd ba43d7fec5 do not spew about processes which have had fatal traps, unless DEBUG 
is defined.  Actually, it never should do it, but DEBUG should be 'never'
for most users.
