kernel - Major SMP performance patch / VM system, bus-fault/seg-fault fixes
This is a very large patch which reworks locking in the entire VM subsystem,
concentrated on VM objects and the x86-64 pmap code. These fixes remove
nearly all the spin lock contention for non-threaded VM faults and narrows
contention for threaded VM faults to just the threads sharing the pmap.
Multi-socket many-core machines will see a 30-50% improvement in parallel
build performance (tested on a 48-core opteron), depending on how well
the build parallelizes.
As part of this work a long-standing problem on 64-bit systems where programs
would occasionally seg-fault or bus-fault for no reason has been fixed. The
problem was related to races between vm_fault, the vm_object collapse code,
and the vm_map splitting code.
* Most uses of vm_token have been removed. All uses of vm_spin have been
removed. These have been replaced with per-object tokens and per-queue
(vm_page_queues[]) spin locks.
Note in particular that since we still have the page coloring code the
PQ_FREE and PQ_CACHE queues are actually many queues, individually
spin-locked, resulting in very excellent MP page allocation and freeing
performance.
* Reworked vm_page_lookup() and vm_object->rb_memq. All (object,pindex)
lookup operations are now covered by the vm_object hold/drop system,
which utilize pool tokens on vm_objects. Calls now require that the
VM object be held in order to ensure a stable outcome.
Also added vm_page_lookup_busy_wait(), vm_page_lookup_busy_try(),
vm_page_busy_wait(), vm_page_busy_try(), and other API functions
which integrate the PG_BUSY handling.
* Added OBJ_CHAINLOCK. Most vm_object operations are protected by
the vm_object_hold/drop() facility which is token-based. Certain
critical functions which must traverse backing_object chains use
a hard-locking flag and lock almost the entire chain as it is traversed
to prevent races against object deallocation, collapses, and splits.
The last object in the chain (typically a vnode) is NOT locked in
this manner, so concurrent faults which terminate at the same vnode will
still have good performance. This is important e.g. for parallel compiles
which might be running dozens of the same compiler binary concurrently.
* Created a per vm_map token and removed most uses of vmspace_token.
* Removed the mp_lock in sys_execve(). It has not been needed in a while.
* Add kmem_lim_size() which returns approximate available memory (reduced
by available KVM), in megabytes. This is now used to scale up the
slab allocator cache and the pipe buffer caches to reduce unnecessary
global kmem operations.
* Rewrote vm_page_alloc(), various bits in vm/vm_contig.c, the swapcache
scan code, and the pageout scan code. These routines were rewritten
to use the per-queue spin locks.
* Replaced the exponential backoff in the spinlock code with something
a bit less complex and cleaned it up.
* Restructured the IPIQ func/arg1/arg2 array for better cache locality.
Removed the per-queue ip_npoll and replaced it with a per-cpu gd_npoll,
which is used by other cores to determine if they need to issue an
actual hardware IPI or not. This reduces hardware IPI issuance
considerably (and the removal of the decontention code reduced it even
more).
* Temporarily removed the lwkt thread fairq code and disabled a number of
features. These will be worked back in once we track down some of the
remaining performance issues.
Temproarily removed the lwkt thread resequencer for tokens for the same
reason. This might wind up being permanent.
Added splz_check()s in a few critical places.
* Increased the number of pool tokens from 1024 to 4001 and went to a
prime-number mod algorithm to reduce overlaps.
* Removed the token decontention code. This was a bit of an eyesore and
while it did its job when we had global locks it just gets in the way now
that most of the global locks are gone.
Replaced the decontention code with a fall back which acquires the
tokens in sorted order, to guarantee that deadlocks will always be
resolved eventually in the scheduler.
* Introduced a simplified spin-for-a-little-while function
_lwkt_trytoken_spin() that the token code now uses rather than giving
up immediately.
* The vfs_bio subsystem no longer uses vm_token and now uses the
vm_object_hold/drop API for buffer cache operations, resulting
in very good concurrency.
* Gave the vnode its own spinlock instead of sharing vp->v_lock.lk_spinlock,
which fixes a deadlock.
* Adjusted all platform pamp.c's to handle the new main kernel APIs. The
i386 pmap.c is still a bit out of date but should be compatible.
* Completely rewrote very large chunks of the x86-64 pmap.c code. The
critical path no longer needs pmap_spin but pmap_spin itself is still
used heavily, particularin the pv_entry handling code.
A per-pmap token and per-pmap object are now used to serialize pmamp
access and vm_page lookup operations when needed.
The x86-64 pmap.c code now uses only vm_page->crit_count instead of
both crit_count and hold_count, which fixes races against other parts of
the kernel uses vm_page_hold().
_pmap_allocpte() mechanics have been completely rewritten to remove
potential races. Much of pmap_enter() and pmap_enter_quick() has also
been rewritten.
Many other changes.
* The following subsystems (and probably more) no longer use the vm_token
or vmobj_token in critical paths:
x The swap_pager now uses the vm_object_hold/drop API instead of vm_token.
x mmap() and vm_map/vm_mmap in general now use the vm_object_hold/drop API
instead of vm_token.
x vnode_pager
x zalloc
x vm_page handling
x vfs_bio
x umtx system calls
x vm_fault and friends
* Minor fixes to fill_kinfo_proc() to deal with process scan panics (ps)
revealed by recent global lock removals.
* lockmgr() locks no longer support LK_NOSPINWAIT. Spin locks are
unconditionally acquired.
* Replaced netif/e1000's spinlocks with lockmgr locks. The spinlocks
were not appropriate owing to the large context they were covering.
* Misc atomic ops added

When swapping the top two tokens where tok1 == tok2, the token
can wind up being repointed to the top ref instead of the deeper

release even though there was another deeper ref to the same

kernel - Numerous VM MPSAFE fixes
* Remove most critical sections from the VM subsystem, these are no longer
applicable (vm_token covers the access).
* _pmap_allocpte() for x86-64 - Conditionalize the zeroing of the vm_page
after the grab. The grab can race other threads and result in a page
which had already been zero'd AND populated with pte's, so we can't just
zero it.
Use m->valid to determine if the page is actually newly allocated or not.
NOTE: The 32 bit code already properly zeros the page by detecting whether
the pte has already been entered or not. The 64-bit code couldn't
do this neatly so we used another method.
* Hold the pmap vm_object in pmap_release() and pmap_object_init_pt() for
the x86-64 pmap code. This prevents related loops from blocking on the
pmap vm_object when freeing VM pages which is not expected by the code.
* pmap_copy() for x86-64 needs the vm_token, critical sections are no longer
sufficient.
* Assert that PG_MANAGED is set when clearing pte's out of a pmap via the
PV entries. The pte's must exist in this case and it's a critical panic
if they don't.
* pmap_replacevm() for x86-64 - Adjust newvm->vm_sysref prior to assigning
it to p->p_vmspace to handle any potential MP races with other sysrefs
on the vmspace.
* faultin() needs p->p_token, not proc_token.
* swapout_procs_callback() needs p->p_token.
* Deallocate the VM object associated with a vm_page after freeing the
page instead of before freeing the page. This fixes a potential
use-after-refs-transition-to-0 case if a MP race occurs.
