5cf1e3c8c0 Add a placeholder for the ServerWorks OSB4 device id. The SMBus
interface on this chip is compatable with the PIIX4.  The catch is that
this interferes with isab0 which wants to attach to the same PCI node.
It seems to work, but we only tested it on systems with no ISA cards.

73e89fa2d4 Remember to actually program the MAC address into the unicast filter
in vr_init(). The VIA Rhine chip happens to be able to automatically
read its station address from the EEPROM automatically when reset,
so you don't need to program the filter if you want to keep using the
factory default address, but if you want to change it with "ifconfig vr0
ether xx:xx:xx:xx:xx:xx" then we need to manually set it in the init
routine.

Interrupt entropy harvesting is still conditional on the

e979bff557 Workaround to prevent VMware from melting down. The pseudo PCnet interface
in VMware reports 0x00000000 in the PCI subsystem ID register, but
0x10001000 when you read the mirror registers in I/O space. This causes
pcn_probe() to think it's found a card in 32-bit mode, and performing
a 32-bit I/O access makes on a 16-bit port makes VMware go boom. Special
case the 0x10001000 value until somebody at VMware grows a clue.

07f65363cd Big round of minor updates:
- Use pci_get_powerstate()/pci_set_powerstate() in all the other drivers
  that need them so we don't have to fiddle with the PCI power management
  registers directly.
- Use pci_enable_busmaster()/pci_enable_io() to turn on busmastering and
  PIO/memory mapped accesses.
- Add support to the RealTek driver for the D-Link DFE-530TX+ which has
  a RealTek 8139 with its own PCI ID. (Submitted by Jason Wright)
- Have the SiS 900/National DP83815 driver be sure to disable PME
  mode in sis_reset(). This apparently fixes a problem on some
  motherboards where the DP83815 chip fails to receive packets.

d88a358c86 Add a check in the interrupt service routine to return quickly in
case there is nothing to do. This happens normally when the card shares
the interrupt line with other devices.

This code saves a couple of microseconds per interrupt even on a
fast CPU. You normally would not care, except under heavy tinygram
traffic where you can have some 50-100.000 interrupts per second...

On passing, correct a spelling error.

9ed346bab0 Change and clean the mutex lock interface.
mtx_enter(lock, type) becomes:

mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks)
mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized)

similarily, for releasing a lock, we now have:

mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN.
We change the caller interface for the two different types of locks
because the semantics are entirely different for each case, and this
makes it explicitly clear and, at the same time, it rids us of the
extra `type' argument.

The enter->lock and exit->unlock change has been made with the idea
that we're "locking data" and not "entering locked code" in mind.

Further, remove all additional "flags" previously passed to the
lock acquire/release routines with the exception of two:

MTX_QUIET and MTX_NOSWITCH

The functionality of these flags is preserved and they can be passed
to the lock/unlock routines by calling the corresponding wrappers:

mtx_{lock, unlock}_flags(lock, flag(s)) and
mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN
locks, respectively.

Re-inline some lock acq/rel code; in the sleep lock case, we only
inline the _obtain_lock()s in order to ensure that the inlined code
fits into a cache line. In the spin lock case, we inline recursion and
actually only perform a function call if we need to spin. This change
has been made with the idea that we generally tend to avoid spin locks
and that also the spin locks that we do have and are heavily used
(i.e. sched_lock) do recurse, and therefore in an effort to reduce
function call overhead for some architectures (such as alpha), we
inline recursion for this case.

Create a new malloc type for the witness code and retire from using
the M_DEV type. The new type is called M_WITNESS and is only declared
if WITNESS is enabled.

Begin cleaning up some machdep/mutex.h code - specifically updated the
"optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN
and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently
need those.

Finally, caught up to the interface changes in all sys code.

c27eb220c2 Apply patch to add support for the intergrated ethernet in the SiS630E
chipset. The MAC address is stored in the APC CMOS RAM and we have to
commit trememdous evil in order to read it. The code to do this is only

18d5982009 Update these netgraph drivers in current so that these changes can be
MFC'ed i due time.  I can't test it under current right now because
netgraph seems to do unethical things with mutexes.

musycc:
	Add status per channel.
	Reduce printf chattyness
	Keep error counters line if_mn does.
	Increase descriptor count.

if_mn:
	Support experimental unframed E1 lines.

These two drivers should share more code relating to framed channelized
TDM media in general (T1/E1/E3/T3, Sonet).  Anyone interested email me.

419146d944 Bug fixes that I've put together while working on a project in the office:
if_vr: handle the case where vr_encap() returns failure: bust out of the
       packet sending loop instead of panicking. Also add some missing
       newlines to some printf()s.

if_dc: The miibus_read and miibus_write methods keep swapping in and
       out of MII mode by fiddling with CSR6 for cards with MII PHYs.
       This is a hack to support the original Macronix 98713 card which
       has built-in NWAY that uses an MII-like management interface
       even though it uses serial transceivers. Conditionalize this
       so that we only do this on 98713 chips, since it does bad things
       to genuine tulip chips (and maybe other clones).

08812b3925 Implement MTX_RECURSE flag for mtx_init().
All calls to mtx_init() for mutexes that recurse must now include
the MTX_RECURSE bit in the flag argument variable. This change is in
preparation for an upcoming (further) mutex API cleanup.
The witness code will call panic() if a lock is found to recurse but
the MTX_RECURSE bit was not set during the lock's initialization.

The old MTX_RECURSE "state" bit (in mtx_lock) has been renamed to
MTX_RECURSED, which is more appropriate given its meaning.

The following locks have been made "recursive," thus far:
eventhandler, Giant, callout, sched_lock, possibly some others declared
in the architecture-specific code, all of the network card driver locks
in pci/, as well as some other locks in dev/ stuff that I've found to
be recursive.

2a0c503e7a * Rename M_WAIT mbuf subsystem flag to M_TRYWAIT.
This is because calls with M_WAIT (now M_TRYWAIT) may not wait
  forever when nothing is available for allocation, and may end up
  returning NULL. Hopefully we now communicate more of the right thing
  to developers and make it very clear that it's necessary to check whether
  calls with M_(TRY)WAIT also resulted in a failed allocation.
  M_TRYWAIT basically means "try harder, block if necessary, but don't
  necessarily wait forever." The time spent blocking is tunable with
  the kern.ipc.mbuf_wait sysctl.
  M_WAIT is now deprecated but still defined for the next little while.

* Fix a typo in a comment in mbuf.h

* Fix some code that was actually passing the mbuf subsystem's M_WAIT to
  malloc(). Made it pass M_WAITOK instead. If we were ever to redefine the
  value of the M_WAIT flag, this could have became a big problem.

8983cfbf27 Next round of PCI subsystem updates:
- Break out the /dev/pci driver into a separate file.
 - Kill the COMPAT_OLDPCI support.
 - Make the EISA bridge attach a bit more like the old code; explicitly
   check for the existence of eisa0/isa0 and only attach if they don't
   already exist.  Only make one bus_generic_attach() pass over the
   bridge, once both busses are attached.  Note that the stupid Intel
   bridge's class is entirely unpredictable.
 - Add prototypes and re-layout the core PCI modules in line with
   current coding standards (not a major whitespace change, just moving
   the module data to the top of the file).
 - Remove redundant type-2 bridge support from the core PCI code; the
   PCI-CardBus code does this itself internally.  Remove the now
   entirely redundant header-class-specific support, as well as the
   secondary and subordinate bus number fields.  These are bridge
   attributes now.
 - Add support for PCI Extended Capabilities.
 - Add support for PCI Power Management.  The interface currently
   allows a driver to query and set the power state of a device.
 - Add helper functions to allow drivers to enable/disable busmastering
   and the decoding of I/O and memory ranges.
 - Use PCI_SLOTMAX and PCI_FUNCMAX rather than magic numbers in some
   places.
 - Make the PCI-PCI bridge code a little more paranoid about valid
   I/O and memory decodes.
 - Add some more PCI register definitions for the command and status
   registers.  Correct another bogus definition for type-1 bridges.
