kleink 182e12f413 Remove inclusions of syscall (and syscall argument) related header files; 
we don't need them here.

matthias fceafcf990 port-pc532 now has pmap_new just like port-i386. 1998-04-25 19:58:58 +00:00
chuck fe4846acdc have ddb show map print resident page count 1998-03-30 17:34:58 +00:00
thorpej b65c510879 Split uvmspace_alloc() into uvmspace_alloc() and uvmspace_init(). The latter 
can be used for initializing a pre-allocated vmspace.

chuck dd370f11a3 rework the copy inheritance case of fork. the old way did not handle 
the very rare case of shared mappings that have amap's attached in a
reasonable way -- this is not currently causing any problems, but i
fixed it anyway.  update the comment in this section of code and also
be smarter about avoiding needless calls to pmap_protect().

thorpej dbc7bbee68 Make the previous change `atomic'. 1998-03-19 06:37:26 +00:00
thorpej daade671ae When unsharing or execing, deactivate the old vmspace before reassigning 
and activating the new one.  Pointed out by Chris Demetriou.

mrg be92b169f8 oops, missed a bit of KNF here. 1998-03-17 07:50:08 +00:00

chuck cbd05b1537 be consistent about offsets in kernel objects. vm_map_min(kernel_map) 
should always be the base [fixes problem on m68k detected by jason thorpe]

add comments to uvm_km.c explaining kernel memory management in more detail

drochner 93a065690b fix map range boundary check 1998-02-18 14:50:32 +00:00
mrg d90485202c - add defopt's for UVM, UVMHIST and PMAP_NEW. 
- remove unnecessary UVMHIST_DECL's.
 1998-02-10 14:08:44 +00:00
mrg d9b2f81e27 move pdhist initialisation to the same place as maphist. also, declare 
the history buffers are "struct uvm_history_ent" to ensure proper
alignment (eg, alpha).  this fixes a boottime panic when the pdhist was
used before it had been initialised.

mrg 5e55ce6648 bzero the entire vmspace, like the old vm does. makes ps report sane values of VSZ for swapper/pagedaemon 1998-02-07 12:31:32 +00:00

mrg f2caacc717 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 UVM kernel code portion.


this will be KNF'd shortly.  :-)
