mycroft 9e21b6555a In the `MY THAT'S GROSS' department... 
Eliminate the recursive include of machine/endian.h from sys/endian.h.
 2000-03-17 00:09:18 +00:00
mycroft 02905321b2 Foolish consistency. Mainly, always use underscores and sys/endian.h. 2000-03-16 15:09:34 +00:00

cgd 7d16ac338c add __BROKEN_CONFIG_UNIT_USAGE #define, becuase these ports do very

eeh 793cc7a41b Update to post 1.4. 1999-10-11 01:57:43 +00:00
eeh cb2f2c8f26 Add RODATA() macro. 1999-10-05 03:34:41 +00:00
simonb 3c185af5fd Include <sys/endian.h> after defining whether where are little- or 
big-endian.  i386, pc532 and vax still include <machine/byte_swap.h>
and define macros for the {n,h}to{h,n}*() functions.  mips also
defines some endian-independent assembly-code aliases for unaligned
memory accesses.
 1999-08-21 05:53:50 +00:00
simonb 06a92524c2 Include <sys/bswap.h> for function prototypes. i386, pc532 and vax 
still include <machine/byte_swap.h> and define macros for some of
the bswap*() functions.
 1999-08-21 05:39:51 +00:00
thorpej 28fb7c1eb8 Define cpu_number() as discussed on tech-smp. 1999-08-10 21:08:05 +00:00
thorpej 2ff657adb8 Fix the raise/lower semantics of splsoftclock()/spllowersoftclock(). 1999-08-05 18:28:01 +00:00
thorpej eb20bbc780 Change the semantics of splsoftclock() to be like other spl*() functions, 
that is priority is rasied.  Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX.  This platforms still have this bug until their
XXX spl*() functions are fixed.
 1999-08-05 18:08:08 +00:00
thorpej 6ec1ededf1 Make a slight rearrangement in how <machine/lock.h> is included. 1999-07-27 23:45:13 +00:00
thorpej cc668e410f Define apporpriate an value for SIMPLELOCK_LOCKED, based on the 
semantics of ldstub.
 1999-07-27 22:22:33 +00:00
thorpej c1ee8f0a8c Prepend `cpu_' to the machine-dependent atomic locking primitivies. 1999-07-27 21:45:39 +00:00
eeh c6a358d0a8 Lower spl for softints. 1999-07-18 23:54:20 +00:00
eeh 9cf2782159 Move the DVMA mapin/mapout functions from the SBus driver to the iommu driver. 1999-06-20 00:51:29 +00:00
mrg 30c351dc59 mmm, missing return types make gcc unhappy. 1999-06-08 10:35:36 +00:00
eeh 1884f05354 Another general cleanup: 
Remove the entire idea of fasttrap interrupts since V9 traps are really cheap,
the CPUs are really fast, and the completely different trap frames would make
these handlers really difficult to implement.

pmap_changeprot() was only used by the clock and one other place; deprecate it.

probeget() and probeset() now take 64-bit addresses even in 32-bit mode so we
can probe IO locations by physical addresses.

Some pmap cleanup.

Some more copyright cleanup.
 1999-06-07 05:28:03 +00:00
eeh 186c3eba2b Make pbrobeget() and probeset() work for 64-bit values as well. To do this 
the arguments are changed so the address is first and the ASI second so we
can have the address in %o0:%o1 and not worry about unused registers.

Also a bit of copyright cleanup.
