thorpej 6e89972d82 Split vmspace_alloc() into vmspace_alloc() and vmspace_init(). The latter 
can be used for initializing a pre-allocated vmspace.

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.

fvdl e5bc90f40c Merge with Lite2 + local changes 1998-03-01 02:20:01 +00:00
mrg a20d56e92e add new version of non contiguous memory code, written by chuck cranor, 
called "MACHINE_NEW_NONCONGIG".  this is required for UVM, the new VM
system (also written by chuck) that is coming soon.  adds new functions:
	vm_page_physload() -- tell the VM system about an area of memory.
	vm_physseg_find() -- returns index in vm_physmem array that this
		address is in.
and several new versions of old functions/macros defined in vm_page.h.

this is the MI portion.  sparc, and then later i386 portions to come.
all other ports need to change to this ASAP!  (alpha is already being
worked on)

thorpej 5739c88a75 Implement address space sharing (by keeping ref counts on the vmspace 
structure).  Many thanks to Chuck Cranor for debugging assistence.

thorpej a322314f51 Split out the code that prepares a VM space for exec into a new 
vmspace_exec() function.

christos b82d33e84c PR/4269: Chris Demetriou: msync is missing the MS_* flags. 
Also change caddr_t syscall arguments to void *
 1997-10-16 23:29:26 +00:00
fvdl 206e9582ef Move lock.h and kern_lock.c to their rightful places, as in Lite2. Make 
the VM code use the new interface.
 1997-07-06 12:38:25 +00:00
gwr 09da7e273e Eliminate vmspace.vm_pmap and all references to it unless 
__VM_PMAP_HACK is defined (for temporary compatibility).
The __VM_PMAP_HACK code should be removed after all the
ports that define it have removed all vm_pmap references.

brezak 9d7e246a03 Cleanup pretty printers for maps and objects. 1993-07-22 13:03:36 +00:00
cgd b8b3b4471d get rid of any support for vm_fault_wire() returning a result. 
if it's going to be ifdef'd out until it's tested, it shouldn't
be put in to begin with.
also, minor ansifications and cleanups (mostly so tags would be happier).
 1993-07-15 14:25:18 +00:00
andrew 918a434644 ANSIfications. Added support for vm_fault_wire() returning a result; code 
to actually fail is currently disabled, as this would enable some new code
in vm_map_pageable() (disabled in this commit) that hasn't been used to
date.  I'm fairly confident it is all OK, but shall test it some more once
the rest of the kernel is more stable, before enabling it.

cgd 3cac22992d from sean eric fagan: 
it seems to keep the vm system from deadlocking the system when it runs
out of swap + physical memory.
prevents the system from giving the last page(s) to anything but the
referenced "processes" (especially important is the pager process,
which should never have to wait for a free page).
