simonb 18b2f7e6a1 Add a port to IBM's PPC405GP Reference Board (the "walnut") 
by Eduardo Horvath and Simon Burge of Wasabi Systems.

IBM 4xx series CPU features:
 - New pmap and revised trap handler.
 - Support on-chip timers, PCI controller, UARTs
 - Framework for on-chip ethernet and watchdog timer.
General PowerPC features:
 - Add in-kernel PPC floating point emulation
 - New in{,4}_cksum that is between 1.5 and 5 times faster than the
   old version depending on CPU type.
General changes:
 - Kernel support for generic dbsym-style symbols.

briggs c97896cd4d Pull avail_start/avail_end logic for bus_dmamem_alloc() from macppc port, 
as suggested by matt@netbsd.org--the vm_physmem array may not be in order.
 2001-06-10 02:31:25 +00:00

matt b590763f79 Call __syncicache in db_write_bytes. (makes breakpoints work better). 2001-05-18 20:38:27 +00:00
simonb 96a430ba30 If _SOFT_FLOAT is defined, pull floating point va_args from the GPR 
area and not the FPR area (by having the double argument type test
always fail).

Fixes problems using <stdarg.h> with -msoft-float.
 2001-05-16 15:41:03 +00:00
simonb b3a4957ee5 Fix spr and tbr register number extraction. tbr is untested, but is the 
same format as spr and had the same mistake.

simonb 6a511e05e2 Be consistent with limit constants: 
- use "U" suffix for unsigned constants
 - use "L" suffix for long constants
 - use "UL" suffix for unsigned long constants
 - use hexadecimal instead of decimal

Fixes build problems with vi (now that warnings/errors are enabled) on
mips, powerpc and arm platforms.

soren 945b972563 PPC machine type tags haven't been used for a while. 2001-05-03 13:11:24 +00:00
martin 77a926d775 Avoid nesting structure declarations, where the nested structur is used at 
the global level later. Besides stylistic matters, this actually breaks C++
programs (indirectly) using this header.
 2001-04-30 15:30:39 +00:00
kleink fe3c9ceaf7 * Move definitions of exact-width integer types from <machine/types.h> 
to <sys/types.h> and <sys/stdint.h>.
* Add a new C99 <stdint.h> header, which provides integer types of
  explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
  macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for
  intmax_t, pointer-type and size_t arguments.

kleink 99054d7a6c Add definitions for C99 fastest minimum-width integer types. 2001-04-26 16:25:19 +00:00
thorpej 1c3a62e066 Sprinkle pmap_update() calls after calls to: 
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).

These calls are relatively conservative.  It may be possible to
optimize these a little more.
 2001-04-24 04:30:50 +00:00
thorpej 55044638aa Remove pmap_kenter_pgs(). It was never really adopted by 
anything, and the interface itself wasn't as flexible as
callers would have probably liked.
 2001-04-22 23:42:11 +00:00
thorpej 69abdbf60c Undo a misguided previous change to the pmap_update() API. 2001-04-22 23:19:26 +00:00
thorpej 4738622712 Give pmap_update() an argument (a pmap_t) so that it knows which 
pmap it should be updating.
 2001-04-22 00:33:59 +00:00
thorpej 7f10ba88b1 #define away pmap_update() in <machine/pmap.h> so that no function 
call overhead is incurred as we start sprinkling pmap_update() calls
throughout the source tree (no pmaps currently defer operations, but
we are adding the infrastructure to allow them to do so).
 2001-04-21 23:51:14 +00:00

XXX Fastest minimum-width integer types haven't been decided upon yet.
 2001-04-14 12:19:49 +00:00
kleink 9133b51cd8 Replace the 'unsigned __COMPILER_INT64__' construct with a new name, 
__COMPILER_UINT64__, to be supplied - if such a case is made, it shouldn't
be assumed that the unsigned type-specifier may be applied to it.
