scw 9beeeabe1b Define a PAGER_MAP_SIZE of 4MB for the benefit of low-memory models. 
XXX: This may still not be low enough for models with less than 8MB RAM...

scw dd8c947561 Implement a real microtime() by reading the timer counter register. 
On mvme147 this gives 6.25uS resolution, and 1uS on all other boards.

thorpej bf2dcec4f5 Remove the use of splimp() from the NetBSD kernel. splnet() 
and only splnet() is allowed for the protection of data structures
used by network devices.

lukem 723cd818d8 move duplicate definitions for: 
pc, lpt, joy, ocis, apm, satlink, i4bctl, i4brbch, i4btel, i4btrc, i4b
from the port-specific arch/*/*/conf.c files into sys/conf.h

chs ac3bc537bd eliminate the KERN_* error codes in favor of the traditional E* codes. 
the mapping is:

KERN_SUCCESS			0
KERN_INVALID_ADDRESS		EFAULT
KERN_PROTECTION_FAILURE		EACCES
KERN_NO_SPACE			ENOMEM
KERN_INVALID_ARGUMENT		EINVAL
KERN_FAILURE			various, mostly turn into KASSERTs
KERN_RESOURCE_SHORTAGE		ENOMEM
KERN_NOT_RECEIVER		<unused>
KERN_NO_ACCESS			<unused>
KERN_PAGES_LOCKED		<unused>

bjh21 fe3273fbb4 Patch from PR kern/8001, submitted by Rafal Boni. 
This adds support for EtherExpress/16 cards with 16k of RAM, and in the
process adds general support for PIO mode on these cards.  This entails
changing the way the i82586 driver handles bus barriers, since it doesn't
allow for strange cases like this.

This has been tested on the i386 port with the 'ix' driver in both
16KB (which was the source of the problem) and 32KB modes, as well
as with the 'ef' driver.  I've tested it (briefly) with 'ei' on arm26
as well.  In theory, drivers other than 'ix' should follow precisely the
same code paths as before.

scw 2c13177ff8 Create machine/m68k symlinks before trying to build the program. 2001-01-21 10:58:04 +00:00
tv e58532a4bf No-op commit to force update to a non-"-kk" revision. 2001-01-18 17:47:58 +00:00
fvdl c7f1462f3e Add machdep file for procfs. Currently only used for linux-style 
/proc/cpuinfo (only active when procfs is mounted with -o linux).
For ports other than the i386 this currently produces an empty
string.

thorpej d74e432ed3 Make softclock a generic soft interrupt of the API is available, 
adding the requisite void * argument to softclock().
 2001-01-15 20:19:50 +00:00
thorpej 45de366b2e Rename __GENERIC_SOFT_INTERRUPTS to __HAVE_GENERIC_SOFT_INTERRUPTS, 
and place the definition in <machine/types.h>.  This can now be used
as a flag to indicate whether or not <machine/intr.h> can be included
to get the generic soft interrupt API.

thorpej a3ec356d52 splimp() -> splvm() 2001-01-14 03:22:04 +00:00
thorpej d85a75f583 Make sure everybody has an splvm() and equate it with splimp() (splimp() 
is the historical name for this interrupt level, and the historical name
is going to go away in the near future).

scw 65137701cf g/c the HP/UX core-dump code; it references a function which no longer exists. 2001-01-11 08:44:36 +00:00
dbj e992baf394 fix logic error in bus_dmamap_sync that was preventing from flush/purging 
full pages instead of only by cache lines

jdolecek de31133f1d split off thread specific stuff from struct sigacts to struct sigctx, leaving 
only signal handler array sharable between threads
move other random signal stuff from struct proc to struct sigctx

This addresses kern/10981 by Matthew Orgass.

XXX I wish m68k ports would share trap.c

scw 8336df62f7 Some small optimisations: 
o Avoid checking cputype when the kernel is built for one cpu variant only.
 o In writeback(), don't use bcopy() to write a mere 16 bytes of 16-byte
   aligned data; it's much quicker to copy it inline.

scw d11562c429 A couple of minor functions which return pointers need to do so in %a0 now. 
Spotted by Chuck Silvers.
 2000-12-22 20:57:21 +00:00
scw 00627955a1 Some minor optimisations to avoid checking {cpu,mmu}type when 
the kernel was built for only one type of CPU.

scw 5d5ebb1b73 Simplify the reboot code: 
Always jump through the PROM's reset vector, regardless of board type.
  Fix a stack offset problem in the mvme147 reset code path.
 2000-12-10 20:00:21 +00:00
scw 8ace7abc75 A small splx()/spl0()/soft interrupt related optimisation. If we're 
dropping to spl0, use inline code to check if a soft interrupt is
pending instead of taking the hit of a function call to do the check.
 2000-12-10 18:43:02 +00:00
scw c5b6f43634 Define `splzs()' to be `splserial()' instead of `spl4()', which was 
wrong anyway since it blindly set SPL to 4 regardless of the prevailing
level.
 2000-12-10 18:00:24 +00:00
scw 1a0a12c5b4 Bah. Somehow the a.out versions of the bootxx symbols got deleted; put 
them back.
 2000-12-09 22:33:24 +00:00
scw a3dc741c03 Delete the commented out EXEC_ELF32 now that it's in std.mvme68k. 
(Spotted by Simon Burge)

scw 3c748b810f Missed this one in yesterday's bootloader commits: 
Change BUGCRT from bugcrt.o to bugstart.o.
 2000-12-07 21:37:51 +00:00
scw 3f7cfb70ef Add "options COMPAT_AOUT_M68K". 2000-12-07 08:40:06 +00:00
scw ac80517816 Add some #defines for offsets into the bugargs structure, and make the 
register names usable within assembly code.
 2000-12-05 21:57:13 +00:00
scw 86c7dac956 Replace the startup C code with assembler, which avoids having to 
explicitly tell the compiler what registers the Bug args come in on.
