b60f56f73b MFS:
Fix amr_map_command so that 40LD-specific commands get the scatter-gather
   list count in the right place.  I don't understand why AMI did it like
   this, but now the AMI MegaManager can talk to the newer (1600 and later)
   controllers.

   Remove an unused variable.

   Include <machine/clock.h> when necessary.

   Tweak some debugging levels to make things more intelligible.

c669d6a002 1) When mucking with mapping registers, it is best to *not* have
io or memory space access enabled.  This patch defers the setting
   of these bits until after all of the mapping registers are probed.
   It might be even better to defer this until a particular mapping
   is activated and to disable that type of access when a new
   register is activated.

2) The PCI spec is very explicit about how mapping registers and
   the expansion ROM mapping register should be probed.  This patch
   makes cardbus_add_map() follow the spec.

3) The PCI spec allows a device to use the same address decoder for
   expansion ROM access as is used for memory mapped register access.
   This patch carefully enables and disables ROM access along with
   resource (de)activiation.

This doesn't include the prefetching detection stuff (maybe later when code is written to actually turn on prefetching).  It also does not use the PCI definitions (yet, I'll try to put this in all at once later)

3) use M_ZERO flag when allocating initial structs instead of calling bzero

df5e198723 Lock down the network interface queues. The queue mutex must be obtained
before adding/removing packets from the queue.  Also, the if_obytes and
if_omcasts fields should only be manipulated under protection of the mutex.

IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on
the queue.  An IF_LOCK macro is provided, as well as the old (mutex-less)
versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which
needs them, but their use is discouraged.

Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF,
which takes care of locking/enqueue, and also statistics updating/start
if necessary.

b3d39a56ae Update the ed driver to probe and attach under a NEWCARD kernel (I was
using a cardbus based system with pccbb providing the pcic interface).
Something isn't quite right.. when the driver allocates and activates
its resources, the IO space that was requested reads as all zeros (versus
the original 0xff's as it normally is when there is no device responding).

Also, deactivate the resources before releasing them.  OLDCARD doesn't
seem to care but NEWCARD/CARDBUS get rather unhappy if you release
a resource that hasn't been deactivated yet.

Make pcic_p.c only compile with oldcard kernels.

0eaa901ba7 Print a warning when we detect a Realtek 8139B chip
(identified by the IO map being 256 bytes long instead of 128)

This chip works very unreliably on my Lanner embedded PC with the rl driver.
Lots of watchdog timeouts or poor performance.

Forcing the media type to 10 Meg (ifconfig rl0 media 10baseT/UTP) is a good
workaround.

This looks very similar to the problem reported in PR kern/18790

It is interesting to note that the linux driver has lots of special
case code for this chip.

a352dd9a71 Fixup (hopefully) bridging + ipfw + dummynet together...
* Some dummynet code incorrectly handled a malloc()-allocated pseudo-mbuf
  header structure, called "pkt," and could consequently pollute the mbuf
  free list if it was ever passed to m_freem(). The fix involved passing not
  pkt, but essentially pkt->m_next (which is a real mbuf) to the mbuf
  utility routines.

* Also, for dummynet, in bdg_forward(), made the code copy the ethernet header
  back into the mbuf (prepended) because the dummynet code that follows expects
  it to be there but it is, unfortunately for dummynet, passed to bdg_forward
  as a seperate argument.

bade6e5e6b Update the probe some more to deal with 16/32 bit issues. If the chip
is already in 32-bit mode, we need to be able to detect this and still
read the chip ID code. Detecting 32-bit mode is actually a little
tricky, since we want to avoid turning it on accidentally. The easiest
way to do it is to just try and read the PCI subsystem ID from the
bus control registers using 16-bit accesses and compare that with the
value read from PCI config space. If they match, then we know we're in
16-bit mode, otherwise we assume 32-bit mode.

This is to be used as a fast "timer", where linearity is more important

This adds no code whatsoever to the FreeBSD kernel until it is actually
used, and then as a single-instruction inline routine (except for the

c6fa9f78d2 Provide a new interface for the user of aio_read() and aio_write() to request

then sigev_notify_kqueue names the kqueue that should receive the event
and sigev_value contains the "void *" is copied into the kevent's udata
field.

In contrast to the existing interface, this one: 1) works on
the Alpha 2) avoids the extra copyin() call for the kevent because all
of the information needed is in the sigevent and 3) could be
applied to request a single kevent upon completion of an entire lio_listio().

71868b020d More aggressively rate limit the growth of soft dependency structures
in the face of multiple processes doing massive numbers of filesystem
operations. While this patch will work in nearly all situations, there
are still some perverse workloads that can overwhelm the system.
Detecting and handling these perverse workloads will be the subject
of another patch.

936524aa02 Implement a low-memory deadlock solution.
Removed most of the hacks that were trying to deal with low-memory
    situations prior to now.

    The new code is based on the concept that I/O must be able to function in
    a low memory situation.  All major modules related to I/O (except
    networking) have been adjusted to allow allocation out of the system
    reserve memory pool.  These modules now detect a low memory situation but
    rather then block they instead continue to operate, then return resources
    to the memory pool instead of cache them or leave them wired.

    Code has been added to stall in a low-memory situation prior to a vnode
    being locked.

    Thus situations where a process blocks in a low-memory condition while
    holding a locked vnode have been reduced to near nothing.  Not only will
    I/O continue to operate, but many prior deadlock conditions simply no
    longer exist.

Implement a number of VFS/BIO fixes

	(found by Ian): in biodone(), bogus-page replacement code, the loop
        was not properly incrementing loop variables prior to a continue
        statement.  We do not believe this code can be hit anyway but we
        aren't taking any chances.  We'll turn the whole section into a
        panic (as it already is in brelse()) after the release is rolled.

	In biodone(), the foff calculation was incorrectly
        clamped to the iosize, causing the wrong foff to be calculated
        for pages in the case of an I/O error or biodone() called without
        initiating I/O.  The problem always caused a panic before.  Now it
        doesn't.  The problem is mainly an issue with NFS.

	Fixed casts for ~PAGE_MASK.  This code worked properly before only
        because the calculations use signed arithmatic.  Better to properly
        extend PAGE_MASK first before inverting it for the 64 bit masking
        op.

	In brelse(), the bogus_page fixup code was improperly throwing
        away the original contents of 'm' when it did the j-loop to
        fix the bogus pages.  The result was that it would potentially
        invalidate parts of the *WRONG* page(!), leading to corruption.

	There may still be cases where a background bitmap write is
        being duplicated, causing potential corruption.  We have identified
        a potentially serious bug related to this but the fix is still TBD.
        So instead this patch contains a KASSERT to detect the problem
  	and panic the machine rather then continue to corrupt the filesystem.
	The problem does not occur very often..  it is very hard to
	reproduce, and it may or may not be the cause of the corruption
	people have reported.

da6e4b77bb When checking the device code in the probe routine, leave the chip in
16-bit mode. Technically, pcn_probe() is destructive because once the
chip goes into 32-bit mode, the only way to get it out again is a
hardware reset. And once the device is in 32-bit mode, the lnc driver
won't be able to talk to it. So if pcn_probe() is called before the
lnc probe routine, and pcn_probe() rejects the chip as one it doesn't
support, the lnc driver will be SOL.

I don't like this. I think it's a design flaw that you can't switch
the chip out of 32-bit mode once it's selected. The only 'right'
solution is for the pcn driver to support all of the PCI devices
in 32-bit mode, however I don't have samples of all the PCnet series
cards for testing.

bd4bd019fb When deleting a file, the ordering of events imposed by soft updates
is to first write the deleted directory entry to disk, second write
the zero'ed inode to disk, and finally to release the freed blocks
and the inode back to the cylinder-group map. As this ordering
requires two disk writes to occur which are normally spaced about
30 seconds apart (except when memory is under duress), it takes
about a minute from the time that a file is deleted until its inode
and data blocks show up in the cylinder-group map for reallocation.
If a file has had only a brief lifetime (less than 30 seconds from
creation to deletion), neither its inode nor its directory entry
may have been written to disk. If its directory entry has not been
written to disk, then we need not wait for that directory block to
be written as the on-disk directory block does not reference the
inode. Similarly, if the allocated inode has never been written to
disk, we do not have to wait for it to be written back either as
its on-disk representation is still zero'ed out. Thus, in the case
of a short lived file, we can simply release the blocks and inode
to the cylinder-group map immediately. As the inode and its blocks
are released immediately, they are immediately available for other
uses. If they are not released for a minute, then other inodes and
blocks must be allocated for short lived files, cluttering up the
vnode and buffer caches. The previous code was a bit too aggressive
in trying to release the blocks and inode back to the cylinder-group
map resulting in their being made available when in fact the inode
on disk had not yet been zero'ed. This patch takes a more conservative
approach to doing the release which avoids doing the release prematurely.

a614c4dc7b Close PR# 21843 and PR# 21864. This adds support for WEP and updates some
of the data structures to include new members that weren't defined in the
manual I have.

I opted to use Doug Ambrisko's WEP patches since David Cornejo's patches
did not include the necessary changes to ancontrol(8) to actually enable
and use WEP.

NOTE: I don't currently have access to an Aironet card, so I can't test
any of this. Everything compiles and close scrutiny doesn't reveal any
obvious problems, but Murphy's Law applies. This means I will probably
leave these changes in -current for a bit longer than usual until I'm
sure they work right.

2c4ab9ddfa Make linux_sendsig and linux_sigreturn use all 64 bits of a
linux_sigset_t by updating the linux_sigframe struct so as to include
linux's "extramask" field.  This field contains the upper 32-bits of
the sigset.  extramask sits behind a linux_fpstate struct, which I've
defined primarily for padding purposes.

While we're here, define LINUX_NSIG in terms of LINUX_NBPW (32) and
LINUX_NSIG_WORDS (2).

This fixes problems where threaded apps would accumulate a large
number of zombies.  This was happening because the exit signal resides
in the upper 32-bits of the sigset and was never getting unmasked by
the manager thread after the first child exited.

72df3c5621 Sync Perforce IDs, add tranceiver state change support, and correct
numerous error recovery buglets.

Many thanks to Tor Egge for his assistance in diagnosing problems with
the error recovery code.

aic7xxx.c:
	Report missed bus free events using their own sequencer interrupt
	code to avoid confusion with other "bad phase" interrupts.

	Remove a delay used in debugging.  This delay could only be hit
	in certain, very extreme, error recovery scenarios.

	Handle transceiver state changes correctly.  You can now
	plug an SE device into a hot-plug LVD bus without hanging
	the controller.

	When stepping through a critical section, panic if we step
	more than a reasonable number of times.

	After a bus reset, disable bus reset interupts until we either
	our first attempt to (re)select another device, or another device
	attemps to select us.  This removes the need to busy wait in
	kernel for the scsi reset line to fall yet still ensures we
	see any reset events that impact the state of either our initiator
	or target roles.  Before this change, we had the potential of
	servicing a "storm" of reset interrupts if the reset line was
	held for a significant amount of time.

	Indicate the current sequencer address whenever we dump the
	card's state.

aic7xxx.reg:
	Transceiver state change register definitions.

	Add the missed bussfree sequencer interrupt code.

	Re-enable the scsi reset interrupt if it has been
	disabled before every attempt to (re)select a device
	and when we have been selected as a target.

	When being (re)selected, check to see if the selection
	dissappeared just after we enabled our bus free interrupt.
	If the bus has gone free again, go back to the idle loop
	and wait for another selection.

	Note two locations where we should change our behavior
	if ATN is still raised.  If ATN is raised during the
	presentation of a command complete or disconnect message,
	we should ignore the message and expect the target to put
	us in msgout phase.  We don't currently do this as it
	requires some code re-arrangement so that critical sections
	can be properly placed around our handling of these two
	events.  Otherwise, we cannot guarantee that the check of
	ATN is atomic relative to our acking of the message in
	byte (the kernel could assert ATN).

	Only set the IDENTIFY_SEEN flag after we have settled
	on the SCB for this transaction.  The kernel looks at
	this flag before assuming that SCB_TAG is valid.  This
	avoids confusion during certain types of error recovery.

	Add a critical section around findSCB.  We cannot allow
	the kernel to remove an entry from the disconnected
	list while we are traversing it.  Ditto for get_free_or_disc_scb.

aic7xxx_freebsd.c:
	Only assume that SCB_TAG is accurate if IDENTIFY_SEEN is
	set in SEQ_FLAGS.

	Fix a typo that caused us to execute some code for the
	non-SCB paging case when paging SCBs.  This only occurred
	during error recovery.

block bitmaps before unmount() completes.  They were written using
bdwrite(), so they were normally written less than 32 seconds after
unmount(), but this is too late if the media is removed or the system
is rebooted soon after unmount().  sync()ing before unmount() didn't
help, because ext2fs uses buggy private caching for these blocks --
it doesn't even bdwrite() them until they are uncached or the filesystem
is unmounted.  sync()ing after unmount() didn't help, because sync()
only applies to (vnodes for) mounted filesystems.

definitions.
This patch was long overdue.

30cb2a0dfb Make the ISA nic section look like the other device sections with
comments on the same line like so:
	device		foo		# FooInc Brand NetEther cards

Also, move the wireless NIC cards to their own section.

Add commented out wl driver in wireless section.

Remove obsolete or redundant comments about some of the wireless cards
that used to apply but don't since we've removed 'at foobus'.

There should be no functional changes in this change.

b5d335ad6d Protect against an infinite loop when prefaulting pages. This can
happen when the vm system maps past the end of an object or tries
to map a zero length object, the pmap layer misses the fact that
offsets wrap into negative numbers and we get stuck.

1d8068f94a Fix for powering off a HP DJ950C during printing. As stated by Ian:
When the printer is turned off the pipe write will cause and error,
which causes lpd to close the device and reopen it to clear the error.
After a short while the device will disappear from the bus but lpd will
have opened the ulpt0 port by then. ulpt_status will check for status
without checking the sc->dying flag and panic the kernel when the device
finally disappears from the bus.

d8f03321bd - Remove much of the inlining of the KTR tracepoints into a ktr_tracepoint()
function declared in kern_ktr.c.  The only inline checks left are the
  checks that compare KTR_COMPILE with the supplied mask and thus should
  be optimized away into either nothing or a direct call to ktr_tracepoint().
- Move several KTR-related options to opt_ktr.h now that they are only
  needed by kern_ktr.c and not by ktr.h.
- Add in the ktr_verbose functionality if KTR_EXTEND is turned on.  If the
  global variable 'ktr_verbose' is non-zero, then KTR messages will be
  dumped to the console.  This variable can be set by either kernel code
  or via the 'debug.ktr_verbose' sysctl.  It defaults to off unless the
  KTR_VERBOSE kernel option is specified in which case it defaults to on.
  This can be useful when the machine locks up spinning in a loop with
  interrupts disabled as you might be able to see what it is doing when it
  locks up.

7d1fae05bb The vortex driver can be compiled as a KLD now. The EISA attachment
is only built on the i386 platform for now, since it depends on symbols
which I'm pretty sure won't be present in the alpha build.

f425f328cd The vx driver no longer needs the PCI compat shims. Also should now
work on the alpha (at least the PCI part should).

de2c27913c Update the vortex driver so that it no longer needs the PCI compat
interface. In addition to using newbus, it also uses bus_space rather
than inb/outb to make it MI. The grody static softc allocation stuff
has been removed as well.
