a4b042e9d1 Put on my nuclear-grade asbestos suit and cvs rm the old, broken, sound
drivers (again).  These drivers have not compiled for 5-6 months.
Now that the new sound code supports MIDI, the major reason we had for
reviving it is gone.  It is a far better investment polishing the new
midi code than trying to keep this on life support.  Come 5.0-REL, if
there are major shortcomings in the pcm sound driver then maybe we can
rethink this, but until then we should focus on pcm.

Remember, these have not been compilable since ~April-May this year.

451ab62921 fix some minor problem in PIOCSRESOURCE ioctl.
- If resource which was allocated for pcic was
  requested via this ioctl, bus_alloc_resource
  would be succeeded and that resource was
  returned as free resource.  So check whether
  requested resource was used for pcic or not
  before bus_alloc_resource test.

- merge SYS_RES_IRQ routine into other SYS_RES_*
  routine and clean up.

432c7cf945 Fix the no-pci case of attaching isa, eisa and mca devices.
device_add_child() is meant to be called by the bus add_child method, not
to replace the bus add_child method.  We could have called nexus_add_device
directly too, that would have also worked.

73f1784807 Big mbuf subsystem diff #1: incorporate mutexes and fix things up somewhat
to accomodate the changes.

 Here's a list of things that have changed (I may have left out a few); for a
 relatively complete list, see http://people.freebsd.org/~bmilekic/mtx_journal

   * Remove old (once useful) mcluster code for MCLBYTES > PAGE_SIZE which
     nobody uses anymore. It was great while it lasted, but now we're moving
     onto bigger and better things (Approved by: wollman).

   * Practically re-wrote the allocation macros in sys/sys/mbuf.h to accomodate
     new allocations which grab the necessary lock.

   * Make sure that necessary mbstat variables are manipulated with
     corresponding atomic() routines.

   * Changed the "wait" routines, cleaned it up, made one routine that does
     the job.

   * Generalized MWAKEUP() macro. Got rid of m_retry and m_retryhdr, as they
     are now included in the generalized "wait" routines.

   * Sleep routines now use msleep().

   * Free lists have locks.

   * etc... probably other stuff I'm missing...

  Things to look out for and work on later:

   * find a better way to (dynamically) adjust EXT_COUNTERS

   * move necessity to recurse on a lock from drain routines by providing
     lock-free lower-level version of MFREE() (and possibly m_free()?).

   * checkout include of mutex.h in sys/sys/mbuf.h - probably violating
     general philosophy here.

   The code has been reviewed quite a bit, but problems may arise... please,
   don't panic! Send me Emails: bmilekic@freebsd.org

04e4b06d1c Get out the roto-rooter and clean up the abuse of nexus ivars by the
i386/isa/pcibus.c.  This gets -current running again on multiple host->pci
machines after the most recent nexus commits.  I had discussed this with
Mike Smith, but ended up doing it slightly differently to what we
discussed as it turned out cleaner this way.  Mike was suggesting creating
a new resource (SYS_RES_PCIBUS) or something and using *_[gs]et_resource(),
but IMHO that wasn't ideal as SYS_RES_* is meant to be a global platform
property, not a quirk of a given implementation.  This does use the ivar
methods but does so properly.  It also now prints the physical pci bus that
a host->pci bridge (pcib) corresponds to.

26212795a8 Shut up some debugging messages that appear to have been left on by
default.

Fix the identify/probe/attach cycle somewhat.  Now in acpi_identify we
parse enough of the RSDT/FACP to find the communications port and
interrupt so that we can establish these as resources on the acpi device.

Pass the softc to acpi_queue_event so that it doesn't dereference NULL
when acpi_intr is invoked in the attach routine (because devclass_get_softc
isn't going to work yet).

Account for our allocated resources properly so that we can free them
if required.

72c8811083 In theory, m_dup should not be necessary, as m_copypacket should be
sifficient. But somewhere (I believe in the UDP stuff), someone is
overwriting an mbuf without calling m_pullup() first. This results in
broad- and multi-cast traffic that is passed through the bridge getting
corrupted.

This should be backed out when there is some assurance that the upper
layers (and I suppose all of the device drivers) are fixed.

6110b03d24 Add a lock structure to vnode structure. Previously it was either allocated
separately (nfs, cd9660 etc) or keept as a first element of structure
referenced by v_data pointer(ffs). Such organization leads to known problems
with stacked filesystems.

From this point vop_no*lock*() functions maintain only interlock lock.
vop_std*lock*() functions maintain built-in v_lock structure using lockmgr().
vop_sharedlock() is compatible with vop_stdunlock(), but maintains a shared
lock on vnode.

If filesystem wishes to export lockmgr compatible lock, it can put an address
of this lock to v_vnlock field. This indicates that the upper filesystem
can take advantage of it and use single lock structure for entire (or part)
of stack of vnodes. This field shouldn't be examined or modified by VFS code
except for initialization purposes.

ahc_pci.c:
	Bring back the AHC_ALLOW_MEMIO option at least until the
	memory mapped I/O problem on the SuperMicro 370DR3 is
	better understood.

aic7xxx.c:
	If we see a spurious SCSI interrupt, attempt to clear it and
	continue by unpausing the sequencer.

	Change the interface to ahc_send_async().  Some async messages
	need to be broadcast to all the luns of a target or all the
	targets of a bus.  This is easier to achieve by passing explicit
	channel, target, and lun parameters instead of attempting to
	construct a device info struct to match.

	Filter the sync parameters for the PPR message in exactly the
	same way we do for an old fashioned SDTR message.

	Correct some typos and correct a panic message.

	Handle rejected PPR messages.

	In ahc_handle_msg_reject(), let ahc_build_transfer_msg() build
	any additional transfer messages instead of doing this inline.

aic7xxx.h:
	Increase the size of both msgout_buf and msgin_buf to
	better accomodate PPR messages.

aic7xxx_freebsd.c:
	Update for change in ahc_send_async() parameters.

aic7xxx_pci.c:
	Check the error register before going into full blown PCI
	interrupt handling.  This avoids a few costly PCI configuration
	space reads when we run our PCI interrupt handler because another
	device sharing our interrupt line is more active than we are.

	Also unpause the sequencer after processing a PCI interrupt.

Previously, these cards were supported by the lnc driver (and they

except the lnc driver runs them in 16-bit LANCE compatibility mode.
The pcn driver runs these chips in 32-bit mode and uses the RX alignment
feature to achieve zero-copy receive. (Which puts it in the same
class as the xl, fxp and tl chipsets.) This driver is also MI, so it
will work on the x86 and alpha platforms. (The lnc driver is still
needed to support non-PCI cards. At some point, I'll need to newbusify

222e32bc49 Implement indirection in the pccard probe/attach. This should make it
possible to have different probe/attach semantics between the two
systems and yet still use the same driver for both.

Compatibility methods for OLDCARD drivers.  We use these routines to make
it possible to call the OLDCARD driver's probe routine in the context that
it expects.  For OLDCARD these are implemented as pass throughs to the
device_{probe,attach} routines.  For NEWCARD they are implemented such
such that probe becomes strictly a matching routine and attach does both
the old probe and old attach.

compat devices should use the following:

	/* Device interface */
	DEVMETHOD(device_probe),	pccard_compat_probe),
	DEVMETHOD(device_attach),	pccard_compat_attach),
	/* Card interface */
	DEVMETHOD(card_compat_match,	foo_match),	/* newly written */
	DEVMETHOD(card_compat_probe,	foo_probe),	/* old probe */
	DEVMETHOD(card_compat_attach,	foo_attach),	/* old attach */

This will allow a single driver binary image to be used for both
OLDCARD and NEWCARD.

Drivers wishing to not retain OLDCARD compatibility needn't do this.

  In other words, privilege does allow a process in jail to modify user
  flags for objects that the process does not own, but privilege will
  not permit the setting of system flags on the file.

  (and hence jail) was available, it would be ok.  In the long run,
  the jail identifier should probably be moved to ucred, as the uidinfo
  information was.

41483dda6f Brought back schedsofttty() (SMPng casualty). Didn't bring back the
other schedsoft*() functions since they have never been used.

Removed confused comment about not needing these functions.  The
functions delay scheduling of SWIs until the next hardclock tick.
For devices that only deliver a few characters per interrupt, this
reduces the number of calls to the scheduler by a large factor (about
115 for each sio port at 115200 bps).

43da3c7d53 Unpessimized CURSIG(). The fast path through CURSIG() was broken in
the 128-bit sigset_t changes by moving conditionally (rarely) executed
code to the beginning where it is always executed, and since this code
now involves 3 128-bit operations, the pessimization was relatively
large.  This change speeds up lmbench's pipe latency benchmark by
3.5%.

very bloated, first with 128-bit sigset_t's, then with locking in the
SMP case, then with locking in all cases.  The space bloat was probably
also time bloat, partly because the fast path through CURSIG() was
pessimized by the sigset_t changes.  This change speeds up lmbench's
pipe-based latency benchmark by 4% on a Celeron.  <sys/signalvar.h>
had become very polluted to support the bloat.

this does not affect the behavior of the ISI rsvpd but allows
another rsvp implementation (e.g., KOM rsvp) to take advantage
of the new style for particular sockets while using the old style
for others.

in the future, rsvp supporn should be replaced by more generic
router-alert support.

02544af7d4 Add new flag PDIRUNLOCK to the component.cn_flags which should be set by
filesystem lookup() routine if it unlocks parent directory. This flag should
be carefully tracked by filesystems if they want to work properly with nullfs
and other stacked filesystems.

VFS takes advantage of this flag to perform symantically correct usage
of vrele() instead of vput() if parent directory already unlocked.

If filesystem fails to track this flag then previous codepath in VFS left
unchanged.

Convert UFS code to set PDIRUNLOCK flag if necessary. Other filesystmes will
be changed after some period of testing.

3599553fbc Change the interface to pccard_function_init. The interface is such
that it looks for an acceptible one.  Once it finds it, it should set
the resources for the device.  I say "should" because I've not written
that.  Also set an ivar for the child of pccard.  Minor fix to the
attach message printed, we lose the slot number, which I'll have to
restore later.  Adjust the pccard ivar so that we can save the
function that corresponds to this driver so we can enable and disable
it more easily.  Save a pointer to the function so we know what we're
dealing with.

There should be some way for the driver to specify which cfg it wants
to activate.  For now the pccard_function_init function just picks
one, but we'll have to revisit this going forward.  I'm not doing it
now because I'd need some way to activate the card many times and I'm
not sure that is desirable or even safe with some cards.
