Matthew Dillon [Thu, 18 Dec 2008 21:37:37 +0000 (13:37 -0800)]
This is a MAJOR rewrite of usched_bsd4 and related support logic, plus
additional improvements to the LWKT scheduler.

* The LWKT scheduler used to run a user thread not needing the MP lock
  if it was unable to run a kernel thread that did need it, due to some
  other cpu holding the lock.  This created a massive priority inversion

  LWKT no longer does this.  It will happily run other MPSAFE kernel
  threads but as long as kernel threads exist which need the MP lock
  LWKT will no longer switch to a user mode thread.

  Add a new sysctl lwkt.chain_mplock which defaults to 0 (off).  If set
  to 1 LWKT will attempt to use IPIs to notify conflicting cpus when the
  MP lock is available and will also allow user mode threads to run if
  kernel threads are present needing the MP lock (but unable to get it).
  NOTE: Current turning on this feature results in reduced performance,
  though not as bad as pre-patch.

* The main control logic USCHED_BSD4 was almost completely rewritten,
  greatly improving interactivity in the face of cpu bound programs
  such as compiles.

  USCHED_BSD4 no longer needs to use the scheduler helper when the
  system is under load.  The scheduler helper is only used to allow
  one cpu to kick another idle cpu when additional processes are
  present.

  USCHED_BSD4 now takes great advantage of the scheduler's cpu-local
  design and uses a bidding algorithm for processes trying to return
  to user mode to determine which one is the best.  Winners simply
  deschedule losers, and since the loser is clearly not running when
  the winner does this the descheduling operation is ultra simple to
  accomplish.

This is a major revamping of the pageout and low-memory handling code.

The pageout daemon now detects out-of-memory conditions and properly
kills the largest process(es).  This condition occurs when swap is
full (or you have no swap) and most of the remaining VM pages in memory
have become dirty.  With no swap to page to the dirty pages squeeze out
the clean ones.  The pageout daemon detects the case and starts killing
processes.

The pageout daemon now detects stress in the form of excess cpu use
and tries to reduce its cpu footprint when that occurs.  Excess cpu use
can occur when the only pages left in-core are dirty and there is nowhere
to swap them to.  Previously if this case occured the system would basically
just stop working.

These changes make the system truely have VM = RAM+SWAP.  If you 1G of ram
and 1G of swap the system can run up to 2G worth of processes.

Pull in libpcap's new DLTs

This commit targets using system net/bpf.h in libpcap instead of
libpcap's own pcap-bpf.h; mainly to make following code compile:
  #include <pcap.h>
  #include <net/bpf.h>

Reported-by: hasso@
Note:
As of this commit DLT_PFSYNC is changed to 18.  The original define
conflicts with libpcap's define and it looks like both libpcap,
NetBSD and OpenBSD use 18 as DLT_PFSYNC.  This may introduce compat
issue with dump files generated using DLT_PFSYNC before this change.

Sync ciss(4) with FreeBSD's RELENG_4 branch.

This adds support for many Smart Array controllers, fixes a couple of
bugs and cleans up some whitespace issues.
