pk c99d62cc8a Account for changed bus attachment scheme. 1998-03-21 20:23:38 +00:00
pk be7f5a7031 Switch to a bus_space(9)-based device attachment scheme. 
The dma & lebuffer devices behave like busses to accommodate the
OBP layout. For practical purposes, they are implemented as
Sbus "extensions".

pk 165120cfaf Sbus attach arguments and map function prototypes go here. 1998-03-21 20:10:07 +00:00
pk 77f499595c Switch to a bus_space(9)-based device attachment scheme. 
- device attachment arguments contain bus-specific
	  address and interrupt levels.

	- devices must call back on bus map functions to get their
	  addresses and interrupt levels translated properly.

	- sun4m's obio bus is treated like an Sbus slot.

	- the sun4-style obio bus has its own attach arguments
	  and map functions.

structure fields.

pk 83cec33afc Split the fb_setsize() utility in two separate functions: one to be 
used by OBP machines and another one for sun4/eeprom machines.
 1998-03-21 19:42:00 +00:00
pk 66190b4b99 Remove old `confargs' structure which is no longer used; extract the 
structures representing the ROM properties.
Also, define the `mainbus' and `obio' attach arguments here.
 1998-03-21 19:36:27 +00:00
pk 9e69994eaa Add `interrupt establish' and ` device mmap' methods and macros to 
match to the bus tag structure.

pk d19772ea9e Transform `mainbus' attach code to use its own attach arguments. 
Add a couple rom-property helper functions; some overlapping functionality
with existing function, but hold on to the latter for just a while.
 1998-03-21 12:18:25 +00:00

mycroft c1444078b5 Finish making this compile after libkern changes. 1998-02-22 15:25:28 +00:00
mycroft b20ba808f2 Clean up after ffs() change. 
Do *not* set runtime here; the way it was done was highly bogus, and the value
just gets blasted right away by mi_switch().
 1998-02-22 15:13:36 +00:00
mycroft 1638d144ca Always go to splhigh() inside DDB. 1998-02-22 14:07:21 +00:00
mycroft bb0363853f ffs() is identical to the one from libc, so just use that. 
Move random() to libkern.

mycroft 3b9429b248 Minor changes to make all the float.h files match. 1998-02-18 11:01:27 +00:00
thorpej 8354e68508 Remove "class" declarations, and add "devclass" declarations where 
appropriate.  Fix several inconsistencies between device class and
attributes.  Mostly from Chris Demetriou.

mrg d90485202c - add defopt's for UVM, UVMHIST and PMAP_NEW. 
- remove unnecessary UVMHIST_DECL's.
 1998-02-10 14:08:44 +00:00
thorpej da21f06eb5 Remove the pager options; they're in std.sparc, and will stay there 
until UVM is no longer optional.
 1998-02-08 19:24:28 +00:00
thorpej 93b0450b6a Back out previous change (again, grrrr). 1998-02-08 19:23:20 +00:00
tv 40f13df5bc the *PAGER options were moved to the generic config files, but not moved 
out of here (causes duplicate opeion errors) -- fix.

thorpej 1305ecbe62 Allow callers of uvm_km_suballoc() to specify where the base of the 
submap _must_ begin, by adding a "fixed" boolean argument.

chs 17755a8fae fix typo in locking. 1998-02-07 02:36:58 +00:00
thorpej 840bd3d7b3 Back out previous change. Until the default VM system is UVM, these 
"options" ARE required, and leaving them here doens't hurt anything in
the UVM case.

mrg 5e91ce6ef1 initial import of the new virtual memory system, UVM, into -current. 
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the sparc portion.

this will be KNF'd shortly.  :-)
