Add a new, more aggressive allocator for uvm_pglistalloc() to allocate
contiguous physical pages, and try this new allocator if the existing
one fails.  The existing contig allocator only tries to allocate pages
that are already free, which works fine shortly after boot but rarely
works after the system has been up for a while.  The new allocator uses
the pagedaemon to evict pages from memory in the hope that this will
free up a range of pages that satisfies the constraits of the request.
This should help with things like plugging in a USB device, which often
fails for some USB controllers because they can't get contigous memory.

Remove PG_ZERO.  It worked brilliantly on x86 machines from the mid-90s but
having spent an age experimenting with it over the last 6 months on various

Start trying to reduce cache misses on vm_page during fault processing.

- Make PGO_LOCKED getpages imply PGO_NOBUSY and remove the latter.  Mark
  pages busy only when there's actually I/O to do.

- When doing COW on a uvm_object, don't mess with neighbouring pages.  In
  all likelyhood they're already entered.

- Don't mess with neighbouring VAs that have existing mappings as replacing
  those mappings with same can be quite costly.

- Don't enqueue pages for neighbour faults unless not enqueued already, and
  don't activate centre pages unless uvmpdpol says its useful.

Also:

- Make PGO_LOCKED getpages on UAOs work more like vnodes: do gang lookup in
  the radix tree, and don't allocate new pages.

- Fix many assertion failures around faults/loans with tmpfs.

uvmpdpol_pageactive(): the change to not re-activate recently activated
pages worked great with uvm_pageqlock, but it doesn't buy anything any more,
because now the busy pages are likely in a per-CPU queue somewhere waiting
to be processed, and changing the intent on those queued pages costs next
to nothing.  Remove this and get back all the bits in pg->pqflags.

- Add and use wrapper functions that take and acquire page interlocks, and pairs
  of page interlocks.  Require that the page interlock be held over calls to
  uvm_pageactivate(), uvm_pagewire() and similar.

- Solve the concurrency problem with page replacement state.  Rather than
  updating the global state synchronously, set an intended state on
  individual pages (active, inactive, enqueued, dequeued) while holding the
  page interlock.  After the interlock is released put the pages on a 128
  entry per-CPU queue for their state changes to be made real in batch.
  This results in in a ~400 fold decrease in contention on my test system.
  Proposed on tech-kern but modified to use the page interlock rather than
  atomics to synchronise as it's much easier to maintain that way, and
  cheaper.

struct vm_page: cluster fields most heavily used by the page allocator and
uvmpdpol at the start of the structure, so that while under global lock we
need only touch one cache line for each vm_page.  There is still the problem
of vm_page not being aligned, but this seems to drop lock wait time for
(a modified) uvmpdpol and the allocator by 20-30% in a quick test.

Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

Make uvm_map recognize UVM_FLAG_COLORMATCH which tells uvm_map that the
'align' argument specifies the starting color of the KVA range to be returned.

When calling uvm_km_alloc with UVM_KMF_VAONLY, also specify the starting
color of the kva range returned (UMV_KMF_COLORMATCH) and pass those to
uvm_map.

In uvm_pglistalloc, make sure the pages being returned have sequentially
advancing colors (so they can be mapped in a contiguous address range).
Add a few missing UVM_FLAG_COLORMATCH flags to uvm_pagealloc calls.

Make the socket and pipe loan color-safe.

Make the mips pmap enforce strict page color (color(VA) == color(PA)).

Abstraction fix; move physical address -> per-page metadata (struct

help migration to not do that.

Likewise move per-page metadata (struct vm_page *) -> physical
address "forward" conversion code into *.c too.  This is called
only low-layer VM and MD code.

Abstraction fix; move physical address -> physical segment "reverse"
lookup code from uvm_page.h to uvm_page.c.

This code is used by some pmaps to lookup per-page state (PV) from
per-segment metadata (struct vm_physseg).  This is not needed if
UVM looks up physical segment once in fault handler, then directly
passes it to pmap.  This change helps transition to that model.

The only users of vm_physseg_find() are pmap_motorola.c and
powerpc/ibm4xx/pmap.c.

Split physical device segment pages from "managed" to "managed
device".  Cache that information as a flag PG_DEVICE so that callers
don't need to walk physsegs everytime.

Remove PQ_FIXED, which means that page daemon doesn't need to know
device segment pages at all.  But still fault handlers need to know
them.

I think this is what I can do best now.

- vm_page: put listq, pageq into a union alongside a LIST_ENTRY, so we can
  use both types of list.

- Make page coloring and idle zero state per-CPU.

- Maintain per-CPU page freelists. When freeing, put pages onto the local
  CPU's lists and the global lists. When allocating, prefer to take pages
  from the local CPU. If none are available take from the global list as
  done now. Proposed on tech-kern@.

Simplify the way the bounds of the managed kernel virtual address
space is advertised to UVM by making virtual_avail and virtual_end
first-class exported variables by UVM.  Machine-dependent code is
responsible for initializing them before main() is called.  Anything
that steals KVA must adjust these variables accordingly.

This reduces the number of instances of this info from 3 to 1, and
simplifies the pmap(9) interface by removing the pmap_virtual_space()
function call, and removing two arguments from pmap_steal_memory().

This also eliminates some kludges such as having to burn kernel_map
entries on space used by the kernel and stolen KVA.

This also eliminates use of VM_{MIN,MAX}_KERNEL_ADDRESS from MI code,
this giving MD code greater flexibility over the bounds of the managed
kernel virtual address space if a given port's specific platforms can
vary in this regard (this is especially true of the evb* ports).

a whole bunch of changes to improve performance and robustness under load:

 - remove special treatment of pager_map mappings in pmaps.  this is
   required now, since I've removed the globals that expose the address range.
   pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's
   no longer any need to special-case it.
 - eliminate struct uvm_vnode by moving its fields into struct vnode.
 - rewrite the pageout path.  the pager is now responsible for handling the
   high-level requests instead of only getting control after a bunch of work
   has already been done on its behalf.  this will allow us to UBCify LFS,
   which needs tighter control over its pages than other filesystems do.
   writing a page to disk no longer requires making it read-only, which
   allows us to write wired pages without causing all kinds of havoc.
 - use a new PG_PAGEOUT flag to indicate that a page should be freed
   on behalf of the pagedaemon when it's unlocked.  this flag is very similar
   to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the
   pageout fails due to eg. an indirect-block buffer being locked.
   this allows us to remove the "version" field from struct vm_page,
   and together with shrinking "loan_count" from 32 bits to 16,
   struct vm_page is now 4 bytes smaller.
 - no longer use PG_RELEASED for swap-backed pages.  if the page is busy
   because it's being paged out, we can't release the swap slot to be
   reallocated until that write is complete, but unlike with vnodes we
   don't keep a count of in-progress writes so there's no good way to
   know when the write is done.  instead, when we need to free a busy
   swap-backed page, just sleep until we can get it busy ourselves.
 - implement a fast-path for extending writes which allows us to avoid
   zeroing new pages.  this substantially reduces cpu usage.
 - encapsulate the data used by the genfs code in a struct genfs_node,
   which must be the first element of the filesystem-specific vnode data
   for filesystems which use genfs_{get,put}pages().
 - eliminate many of the UVM pagerops, since they aren't needed anymore
   now that the pager "put" operation is a higher-level operation.
 - enhance the genfs code to allow NFS to use the genfs_{get,put}pages
   instead of a modified copy.
 - clean up struct vnode by removing all the fields that used to be used by
   the vfs_cluster.c code (which we don't use anymore with UBC).
 - remove kmem_object and mb_object since they were useless.
   instead of allocating pages to these objects, we now just allocate
   pages with no object.  such pages are mapped in the kernel until they
   are freed, so we can use the mapping to find the page to free it.
   this allows us to remove splvm() protection in several places.

The sum of all these changes improves write throughput on my
decstation 5000/200 to within 1% of the rate of NetBSD 1.5
and reduces the elapsed time for "make release" of a NetBSD 1.5
source tree on my 128MB pc to 10% less than a 1.5 kernel took.

Support dynamic sizing of the page color bins.  We also support
dynamically re-coloring pages; as machine-dependent code discovers
the size of the system's caches, it may call uvm_page_recolor() with
the new number of colors to use.  If the new mumber of colors is
smaller (or equal to) the current number of colors, then uvm_page_recolor()
is a no-op.

The system defaults to one bucket if machine-dependent code does not
initialize uvmexp.ncolors before uvm_page_init() is called.

Note that the number of color bins should be initialized to something
reasonable as early as possible -- for many early memory allocations,
we live with the consequences of the page choice for the lifetime of
the boot.

Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.

Implement page coloring, using a round-robin bucket selection
algorithm (Solaris calls this "Bin Hopping").

This implementation currently relies on MD code to define a
constant defining the number of buckets.  This will change
reasonably soon (MD code will be able to dynamically size
the bucket array).

Changes necessary to implement pre-zero'ing of pages in the idle loop:
- Make page free lists have two actual queues: known-zero pages and
  pages with unknown contents.
- Implement uvm_pageidlezero().  This function attempts to zero up to
  the target number of pages until the target has been reached (currently
  target is `all free pages') or until whichqs becomes non-zero (indicating
  that a process is ready to run).
- Define a new hook for the pmap module for pre-zero'ing pages.  This is
  used to zero the pages using uncached access.  This allows us to zero
  as many pages as we want without polluting the cache.

In order to use this feature, each platform must add the appropropriate
glue in their idle loop.

Merge parts of chs-ubc2 into the trunk:
Add a new type voff_t (defined as a synonym for off_t) to describe offsets
into uvm objects, and update the appropriate interfaces to use it, the
most visible effect being the ability to mmap() file offsets beyond
the range of a vaddr_t.

Originally by Chuck Silvers; blame me for problems caused by merging this
into non-UBC.

- Change uvm_{lock,unlock}_fpageq() to return/take the previous interrupt
  level directly, instead of making the caller wrap the calls in
  splimp()/splx().
- Add a comment documenting that interrupts that cause memory allocation
  must be blocked while the free page queue is locked.

Since interrupts must be blocked while this lock is asserted, tying them
together like this helps to prevent mistakes.

Add support for multiple memory free lists.  There is at least one
default free list, and 0 - N additional free list, in order of descending
priority.

A new page allocation function, uvm_pagealloc_strat(), has been added,
providing three page allocation strategies:

	- normal: high -> low priority free list walk, taking the
	  page off the first free list that has one.

	- only: attempt to allocate a page only from the specified free
	  list, failing if that free list has none available.

	- fallback: if `only' fails, fall back on `normal'.

uvm_pagealloc(...) is provided for normal use (and is a synonym for
uvm_pagealloc_strat(..., UVM_PGA_STRAT_NORMAL, 0); the free list argument
is ignored for the `normal' case).

uvm_page_physload() now specified which free list the pages will be
loaded onto.  This means that some platforms which have multiple physical
memory segments may define additional vm_physsegs if they wish to break
individual physical segments into differing priorities.

Machine-dependent code must define _at least_ the following constants
in <machine/vmparam.h>:

	VM_NFREELIST: the number of free lists the system will have

	VM_FREELIST_DEFAULT: the default freelist (should always be 0,
	but is defined in machdep code so that it's with all of the
	other free list-related constants).

Additional free list names may be defined by machine-dependent code, but
they will only be used by machine-dependent code (e.g. for loading the
vm_physsegs).

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.  :-)
