216ca2346f Migrate the LNA mixing diversity machinery from the AR9285 HAL to the driver.
The AR9485 chip and AR933x SoC both implement LNA diversity.
There are a few extra things that need to happen before this can be
flipped on for those chips (mostly to do with setting up the different
bias values and LNA1/LNA2 RSSI differences) but the first stage is
putting this code into the driver layer so it can be reused.

This has the added benefit of making it easier to expose configuration
options and diagnostic information via the ioctl API.  That's not yet
being done but it sure would be nice to do so.

Tested:

* AR9285, with LNA diversity enabled
* AR9285, with LNA diversity disabled in EEPROM

c2c2fc4d86 Import Kevin Lo's port of urtwn(4) from OpenBSD. urtwn(4) is a driver for the
Realtek RTL8188CU/RTL8192CU USB IEEE 802.11b/g/n wireless cards.
This driver requires microcode which is available in FreeBSD ports:
net/urtwn-firmware-kmod.

Hiren ported the urtwn(4) man page from OpenBSD and Glen just commited a port
for the firmware.

TODO:
- 802.11n support
- Stability fixes - the driver can sustain lots of traffic but has trouble
coping with simultaneous iperf sessions.

b70f530bc7 Bring over the initial static bluetooth coexistence configuration
for the WB195 combo NIC - an AR9285 w/ an AR3011 USB bluetooth NIC.

The AR3011 is wired up using a 3-wire coexistence scheme to the AR9285.

The code in if_ath_btcoex.c sets up the initial hardware mapping
and coexistence configuration.  There's nothing special about it -
it's static; it doesn't try to configure bluetooth / MAC traffic priorities
or try to figure out what's actually going on.  It's enough to stop basic
bluetooth traffic from causing traffic stalls and diassociation from
the wireless network.

To use this code, you must have the above NIC.  No, it won't work
for the AR9287+AR3012, nor the AR9485, AR9462 or AR955x combo cards.

Then you set a kernel hint before boot or before kldload, where 'X'
is the unit number of your AR9285 NIC:

# kenv hint.ath.X.btcoex_profile=wb195

This will then appear in your boot messages:

[100482] athX: Enabling WB195 BTCOEX

This code is going to evolve pretty quickly (well, depending upon my
spare time) so don't assume the btcoex API is going to stay stable.

In order to use the bluetooth side, you must also load in firmware using
ath3kfw and the binary firmware file (ath3k-1.fw in my case.)

Tested:

* AR9280, no interference
* WB195 - AR9285 + AR3011 combo; STA mode; basic bluetooth inquiries
  were enough to cause traffic stalls and disassociations.  This has
  stopped with the btcoex profile code.

TODO:

* Importantly - the AR9285 needs ASPM disabled if bluetooth coexistence
  is enabled.  No, I don't know why.  It's likely some kind of bug to do
  with the AR3011 sending bluetooth coexistence signals whilst the device
  is asleep.  Since we don't actually sleep the MAC just yet, it shouldn't
  be a problem.  That said, to be totally correct:

  + ASPM should be disabled - upon attach and wakeup
  + The PCIe powersave HAL code should never be called

  Look at what the ath9k driver does for inspiration.

* Add WB197 (AR9287+AR3012) support
* Add support for the AR9485, which is another combo like the AR9285
* The later NICs have a different signaling mechanism between the MAC
  and the bluetooth device; I haven't even begun to experiment with
  making that HAL code work.  But it should be a lot more automatic.

* The hardware can do much more interesting traffic weighting with
  bluetooth and wifi traffic.  None of this is currently used.
  Ideally someone would code up something to watch the bluetooth traffic
  GPIO (via an interrupt) and then watch it go high/low; then figure out
  what the bluetooth traffic is and adjust things appropriately.

* If I get the time I may add in some code to at least track this stuff
  and expose statistics.  But it's up to someone else to experiment with
  the bluetooth coexistence support and add the interesting stuff (like
  "real" detection of bulk, audio, etc bluetooth traffic patterns and
  change wifi parameters appropriately - eg, maximum aggregate length,
  transmit power, using quiet time to control TX duty cycle, etc.)

2.  New modinfo for loader provided FDT blob.
3.  Common x86_init_fdt() called from hammer_time() on amd64 and
    init386() on i386.
4.  Split-off FDT specific low-level console functions from FDT
    bus methods for the uart(4) driver. The low-level console
    logic has been moved to uart_cpu_fdt.c and is used for arm,
    mips & powerpc only. The FDT bus methods are shared across
    all architectures.
5.  Add dev/fdt/fdt_x86.c to hold the fdt_fixup_table[] and the
    fdt_pic_table[] arrays. Both are empty right now.

FDT addresses are I/O ports on x86. Since the core FDT code does
not handle different address spaces, adding support for both I/O
ports and memory addresses requires some thought and discussion.
It may be better to use a compile-time option that controls this.

adb974068b Move the NFS FHA (File Handle Affinity) code from sys/nfsserver to
sys/nfs, since it is now shared by the two NFS servers.

d96b98a360 Revamp the old NFS server's File Handle Affinity (FHA) code so that
it will work with either the old or new server.

The FHA code keeps a cache of currently active file handles for
NFSv2 and v3 requests, so that read and write requests for the same
file are directed to the same group of threads (reads) or thread
(writes).  It does not currently work for NFSv4 requests.  They are
more complex, and will take more work to support.

This improves read-ahead performance, especially with ZFS, if the
FHA tuning parameters are configured appropriately.  Without the
FHA code, concurrent reads that are part of a sequential read from
a file will be directed to separate NFS threads.  This has the
effect of confusing the ZFS zfetch (prefetch) code and makes
sequential reads significantly slower with clients like Linux that
do a lot of prefetching.

The FHA code has also been updated to direct write requests to nearby
file offsets to the same thread in the same way it batches reads,
and the FHA code will now also send writes to multiple threads when
needed.

This improves sequential write performance in ZFS, because writes
to a file are now more ordered.  Since NFS writes (generally
less than 64K) are smaller than the typical ZFS record size
(usually 128K), out of order NFS writes to the same block can
trigger a read in ZFS.  Sending them down the same thread increases
the odds of their being in order.

In order for multiple write threads per file in the FHA code to be
useful, writes in the NFS server have been changed to use a LK_SHARED
vnode lock, and upgrade that to LK_EXCLUSIVE if the filesystem
doesn't allow multiple writers to a file at once.  ZFS is currently
the only filesystem that allows multiple writers to a file, because
it has internal file range locking.  This change does not affect the
NFSv4 code.

This improves random write performance to a single file in ZFS, since
we can now have multiple writers inside ZFS at one time.

I have changed the default tuning parameters to a 22 bit (4MB)
window size (from 256K) and unlimited commands per thread as a
result of my benchmarking with ZFS.

The FHA code has been updated to allow configuring the tuning
parameters from loader tunable variables in addition to sysctl
variables.  The read offset window calculation has been slightly
modified as well.  Instead of having separate bins, each file
handle has a rolling window of bin_shift size.  This minimizes
glitches in throughput when shifting from one bin to another.

sys/conf/files:
	Add nfs_fha_new.c and nfs_fha_old.c.  Compile nfs_fha.c
	when either the old or the new NFS server is built.

	Add the malloc wait flag to a newnfs_realign() call.

sys/fs/nfsserver/nfs_nfsdkrpc.c:
	Setup the new NFS server's RPC thread pool so that it will
	call the FHA code.

	Add the malloc flag argument to newnfs_realign().

	Unstaticize newnfs_nfsv3_procid[] so that we can use it in
	the FHA code.

sys/fs/nfsserver/nfs_nfsdsocket.c:
	In nfsrvd_dorpc(), add NFSPROC_WRITE to the list of RPC types
	that use the LK_SHARED lock type.

sys/fs/nfsserver/nfs_nfsdport.c:
	In nfsd_fhtovp(), if we're starting a write, check to see
	whether the underlying filesystem supports shared writes.
	If not, upgrade the lock type from LK_SHARED to LK_EXCLUSIVE.

sys/nfsserver/nfs_fha.c:
	Remove all code that is specific to the NFS server
	implementation.  Anything that is server-specific is now
	accessed through a callback supplied by that server's FHA
	shim in the new softc.

	There are now separate sysctls and tunables for the FHA
	implementations for the old and new NFS servers.  The new
	NFS server has its tunables under vfs.nfsd.fha, the old
	NFS server's tunables are under vfs.nfsrv.fha as before.

	In fha_extract_info(), use callouts for all server-specific
	code.  Getting file handles and offsets is now done in the
	individual server's shim module.

	In fha_hash_entry_choose_thread(), change the way we decide
	whether two reads are in proximity to each other.
	Previously, the calculation was a simple shift operation to
	see whether the offsets were in the same power of 2 bucket.
	The issue was that there would be a bucket (and therefore
	thread) transition, even if the reads were in close
	proximity.  When there is a thread transition, reads wind
	up going somewhat out of order, and ZFS gets confused.

	The new calculation simply tries to see whether the offsets
	are within 1 << bin_shift of each other.  If they are, the
	reads will be sent to the same thread.

	The effect of this change is that for sequential reads, if
	the client doesn't exceed the max_reqs_per_nfsd parameter
	and the bin_shift is set to a reasonable value (22, or
	4MB works well in my tests), the reads in any sequential
	stream will largely be confined to a single thread.

	Change fha_assign() so that it takes a softc argument.  It
	is now called from the individual server's shim code, which
	will pass in the softc.

	Change fhe_stats_sysctl() so that it takes a softc
	parameter.  It is now called from the individual server's
	shim code.  Add the current offset to the list of things
	printed out about each active thread.

	Change the num_reads and num_writes counters in the
	fha_hash_entry structure to 32-bit values, and rename them
	num_rw and num_exclusive, respectively, to reflect their
	changed usage.

	Add an enable sysctl and tunable that allows the user to
	disable the FHA code (when vfs.XXX.fha.enable = 0).  This
	is useful for before/after performance comparisons.

nfs_fha.h:
	Move most structure definitions out of nfs_fha.c and into
	the header file, so that the individual server shims can
	see them.

	Change the default bin_shift to 22 (4MB) instead of 18
	(256K).  Allow unlimited commands per thread.

774d251d99 Sync back vmcontention branch into HEAD:
Replace the per-object resident and cached pages splay tree with a
path-compressed multi-digit radix trie.
Along with this, switch also the x86-specific handling of idle page
tables to using the radix trie.

This change is supposed to do the following:
- Allowing the acquisition of read locking for lookup operations of the
  resident/cached pages collections as the per-vm_page_t splay iterators
  are now removed.
- Increase the scalability of the operations on the page collections.

The radix trie does rely on the consumers locking to ensure atomicity of
its operations.  In order to avoid deadlocks the bisection nodes are
pre-allocated in the UMA zone.  This can be done safely because the
algorithm needs at maximum one new node per insert which means the
maximum number of the desired nodes is the number of available physical
frames themselves.  However, not all the times a new bisection node is
really needed.

The radix trie implements path-compression because UFS indirect blocks
can lead to several objects with a very sparse trie, increasing the number
of levels to usually scan.  It also helps in the nodes pre-fetching by
introducing the single node per-insert property.

This code is not generalized (yet) because of the possible loss of
performance by having much of the sizes in play configurable.
However, efforts to make this code more general and then reusable in
further different consumers might be really done.

The only KPI change is the removal of the function vm_page_splay() which
is now reaped.
The only KBI change, instead, is the removal of the left/right iterators
from struct vm_page, which are now reaped.

89f6b8632c Switch the vm_object mutex to be a rwlock. This will enable in the
future further optimizations where the vm_object lock will be held
in read mode most of the time the page cache resident pool of pages
are accessed for reading purposes.

The change is mostly mechanical but few notes are reported:
* The KPI changes as follow:
  - VM_OBJECT_LOCK() -> VM_OBJECT_WLOCK()
  - VM_OBJECT_TRYLOCK() -> VM_OBJECT_TRYWLOCK()
  - VM_OBJECT_UNLOCK() -> VM_OBJECT_WUNLOCK()
  - VM_OBJECT_LOCK_ASSERT(MA_OWNED) -> VM_OBJECT_ASSERT_WLOCKED()
    (in order to avoid visibility of implementation details)
  - The read-mode operations are added:
    VM_OBJECT_RLOCK(), VM_OBJECT_TRYRLOCK(), VM_OBJECT_RUNLOCK(),
    VM_OBJECT_ASSERT_RLOCKED(), VM_OBJECT_ASSERT_LOCKED()
* The vm/vm_pager.h namespace pollution avoidance (forcing requiring
  sys/mutex.h in consumers directly to cater its inlining functions
  using VM_OBJECT_LOCK()) imposes that all the vm/vm_pager.h
  consumers now must include also sys/rwlock.h.
* zfs requires a quite convoluted fix to include FreeBSD rwlocks into
  the compat layer because the name clash between FreeBSD and solaris
  versions must be avoided.
  At this purpose zfs redefines the vm_object locking functions
  directly, isolating the FreeBSD components in specific compat stubs.

The KPI results heavilly broken by this commit.  Thirdy part ports must
be updated accordingly (I can think off-hand of VirtualBox, for example).

* Illumos zfs issue  [1] LZ4 compression support in ZFS.

LZ4 is a new high-speed BSD-licensed compression algorithm created
by Yann Collet that delivers very high compression and decompression
performance compared to lzjb (>50% faster on compression, >80% faster
on decompression and around 3x faster on compression of incompressible
data), while giving better compression ratio [1].

This version of LZ4 corresponds to upstream's [2] revision 85.

Please note that for obvious reasons this is not backward read
compatible.  This means once a pool have LZ4 compressed data, these
data can no longer be read by older ZFS implementations.

Local changes:

 - On-stack hash table disabled and using kernel slab allocator
   instead, at this time.  This requires larger kernel thread stack
   for zio workers.  This may change in the future should we adjusted
   the zio workers' thread stack size.
 - likely and unlikely will be undefined if they are already defined,
   this is required for i386 XEN build.
 - Removed De Bruijn sequence based __builtin_ctz family of builtins
   in favor of the latter.  Both GCC and clang supports these builtins.
 - Changed the way the LZ4 code detects endianness.
 - Manual pages modifications to mention the feature based on Illumos
   counterpart.
 - Boot loader changes to make it support LZ4 decompression.

b364a5252e Merge Perforce changeset 219940 to head:
Rework altera_avgen(4) to cleanly(ish) separate nexus bus
  attachment from the driver itself.  This should allow us to
  plug in an fdt attachment more easily.

This also removes the kludge from r239009 that covered only
the network driver.

6f1cbda73d Four .c files from OpenBSM are used, in modified form, by the kernel to
implement the BSM audit trail format.  Rename the kernel versions of the
files to match the userspace filenames so that it's easier to work out
what they correspond to, and therefore ensure they are kept in-sync.

372c8c7e5d Dont compile some files in drm with -finline-limit=1350. GCC 4.2.1 doesnt
need that and clang does not support that. This effectively reverts r126542.

5c0adc7db8 Siba, in theory, is a architecturally neutral bus, so place it in
files.  It used to be in files.mips before the clean-room rewrite and
really doesn't belong there.  If we need to grow arch specific code,
we can move it into $ARCH/$ACH/siba_machdep.c.
