6a10f299b9 Send a SIGCONT when detaching or continuing the excution of a traced
process.  This fixes a problem when attaching to a process in gdb
and the process staying in the STOP'd state after quiting gdb.
This whole process seems a bit suspect, but this seems to work.

0b94a66e3f Major bugfix and minor update. This should resolve the current issues
with the driver locking up under load.

 - Restructure so that we use a static pool of commands/FIBs, rather than
   allocating them in clusters.  The cluster allocation just made things
   more complicated, and allowed us to waste more memory in peak load
   situations.
 - Make queueing macros more like my other drivers.  This adds queue stats
   for free.  Add some debugging to take advantage of this.
 - Reimplement the periodic timeout scan.  Kick the interrupt handler
   and the start routine every scan as well, just to be safe.  Track busy
   commands properly.
 - Bring resource cleanup into line with resource allocation.  We should
   now clean up correctly after a failed probe/unload/etc.
 - Try to start new commands when old ones are completed.  We weren't doing
   this before, which could lead to deadlock when the controller was full.
 - Don't try to build a new command if we have found a deferred command.
   This could cause us to lose the deferred command.
 - Use diskerr() to report I/O errors.
 - Don't bail if the AdapterInfo structure is the wrong size.  Some variation
   seems to be normal.  We need to improve our handing of 2.x firmware sets.
 - Improve some comments in an attempt to try to make things clearer.
 - Restructure to avoid some warnings.

2b6b0df712 This implements a better launder limiting solution. There was a solution
in 4.2-REL which I ripped out in -stable and -current when implementing the
low-memory handling solution.  However, maxlaunder turns out to be the saving
grace in certain very heavily loaded systems (e.g. newsreader box).  The new
algorithm limits the number of pages laundered in the first pageout daemon
pass.  If that is not sufficient then suceessive will be run without any
limit.

Write I/O is now pipelined using two sysctls, vfs.lorunningspace and
vfs.hirunningspace.  This prevents excessive buffered writes in the
disk queues which cause long (multi-second) delays for reads.  It leads
to more stable (less jerky) and generally faster I/O streaming to disk
by allowing required read ops (e.g. for indirect blocks and such) to occur
without interrupting the write stream, amoung other things.

NOTE: eventually, filesystem write I/O pipelining needs to be done on a
per-device basis.  At the moment it is globalized.

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.

56a7c4a852 ahc_eisa.c:
ahc_pci.c:
		Add detach support.

		Make use of soft allocated on our behalf by newbus.

		For PCI devices, disable the mapping type we aren't
		using for extra protection from rogue code.

	aic7xxx_93cx6.c:
	aic7xxx_93cx6.h:
		Sync perforce IDs.

	aic7xxx_freebsd.c:
		Capture the eventhandle returned by EVENTHANDER_REGISTER
		so we can kill the handler off during detach.

		Use AHC_* constants instead of hard coded numbers in a
		few more places.

		Test PPR option state when deciding to "really" negotiate
		when the CAM_NEGOTIATE flag is passed in a CCB.

		Make use of core "ahc_pause_and_flushwork" routine in our
		timeout handler rather than re-inventing this code.

		Cleanup all of our resources (really!) in ahc_platform_free().
		We should be all set to become a module now.

		Implement the core ahc_detach() routine shared by all of
		the FreeBSD front-ends.

	aic7xxx_freebsd.h:
		Softc storage for our event handler.

		Null implementation for the ahc_platform_flushwork() OSM
		callback.  FreeBSD doesn't need this as XPT callbacks are
		safe from all contexts and are done directly in ahc_done().

	aic7xxx_inline.h:
		Implement new lazy interrupt scheme.  To avoid an extra
		PCI bus read, we first check our completion queues to
		see if any work has completed.  If work is available, we
		assume that this is the source of the interrupt and skip
		reading INTSTAT.  Any remaining interrupt status will be
		cleared by a second call to the interrupt handler should
		the interrupt line still be asserted.  This drops the
		interrupt handler down to a single PCI bus read in the
		common case of I/O completion.  This is the same overhead
		as in the not so distant past, but the extra sanity of
		perforning a PCI read after clearing the command complete
		interrupt and before running the completion queue to avoid
		missing command complete interrupts added a cycle.

	aic7xxx.c:
		During initialization, be sure to initialize all scratch
		ram locations before they are read to avoid parity errors.
		In this case, we use a new function, ahc_unbusy_tcl() to
		initialize the scratch ram busy target table.

		Replace instances of ahc_index_busy_tcl() used to unbusy
		a tcl without looking at the old value with ahc_unbusy_tcl().

		Modify ahc_sent_msg so that it can find single byte messages.
		ahc_sent_msg is now used to determine if a transfer negotiation
		attempt resulted in a bus free.

		Be more careful in filtering out only the SCSI interrupts
		of interest in ahc_handle_scsiint.

		Rearrange interrupt clearing code to ensure that at least
		one PCI transaction occurrs after hitting CLRSINT1 and
		writting to CLRINT.  CLRSINT1 writes take a bit to
		take effect, and the re-arrangement provides sufficient
		delay to ensure the write to CLRINT is effective.  The
		old code might report a spurious interrupt on some "fast"
		chipsets.

		export ahc-update_target_msg_request for use by OSM code.

		If a target does not respond to our ATN request, clear
		it once we move to a non-message phase.  This avoids
		sending a MSG_NOOP in some later message out phase.

		Use max lun and max target constants instead of
		hard-coded values.

		Use softc storage built into our device_t under FreeBSD.

		Fix a bug in ahc_free() that caused us to delete
		resources that were not allocated.

		Clean up any tstate/lstate info in ahc_free().

		Clear the powerdown state in ahc_reset() so that
		registers can be accessed.

		Add a preliminary function for pausing the chip and
		processing any posted work.

		Add a preliminary suspend and resume functions.

	aic7xxx.h:
		Limit the number of supported luns to 64.  We don't
		support information unit transfers, so this is the
		maximum that makes sense for these chips.

		Add a new flag AHC_ALL_INTERRUPTS that forces the
		processing of all interrupt state in a single invokation
		of ahc_intr().  When the flag is not set, we use the
		lazy interrupt handling scheme.

		Add data structures to store controller state while
		we are suspended.

		Use constants instead of hard coded values where appropriate.

		Correct some harmless "unsigned/signed" conflicts.

	aic7xxx.seq:
		Only perform the SCSIBUSL fix on ULTRA2 or newer controllers.
		Older controllers seem to be confused by this.

		In target mode, ignore PHASEMIS during data phases.
		This bit seems to be flakey on U160 controllers acting
		in target mode.

	aic7xxx_pci.c:
		Add support for the 29160C CPCI adapter.

		Add definitions for subvendor ID information
		available for devices with the "9005" vendor id.
		We currently use this information to determine
		if a multi-function device doesn't have the second
		channel hooked up on a board.

		Add rudimentary power mode code so we can put the
		controller into the D0 state.  In the future this
		will be an OSM callback so that in FreeBSD we don't
		duplicate functionality provided by the PCI code.
		The powerstate code was added after I'd completed
		my regression tests on this code.

		Only capture "left over BIOS state" if the POWRDN
		setting is not set in HCNTRL.

		In target mode, don't bother sending incremental
		CRC data.

b11d7a4a2f We currently does not react to ICMP administratively prohibited
messages send by routers when they deny our traffic, this causes
a timeout when trying to connect to TCP ports/services on a remote
host, which is blocked by routers or firewalls.

rfc1122 (Requirements for Internet Hosts) section 3.2.2.1 actually
requi re that we treat such a message for a TCP session, that we
treat it like if we had recieved a RST.

quote begin.

            A Destination Unreachable message that is received MUST be
            reported to the transport layer.  The transport layer SHOULD
            use the information appropriately; for example, see Sections
            4.1.3.3, 4.2.3.9, and 4.2.4 below.  A transport protocol
            that has its own mechanism for notifying the sender that a
            port is unreachable (e.g., TCP, which sends RST segments)
            MUST nevertheless accept an ICMP Port Unreachable for the
            same purpose.

quote end.

I've written a small extension that implement this, it also create
a sysctl "net.inet.tcp.icmp_admin_prohib_like_rst" to control if
this new behaviour is activated.

When it's activated (set to 1) we'll treat a ICMP administratively
prohibited message (icmp type 3 code 9, 10 and 13) for a TCP
sessions, as if we recived a TCP RST, but only if the TCP session
is in SYN_SENT state.

The reason for only reacting when in SYN_SENT state, is that this
will solve the problem, and at the same time minimize the risk of
this being abused.

I suggest that we enable this new behaviour by default, but it
would be a change of current behaviour, so if people prefer to
leave it disabled by default, at least for now, this would be ok
for me, the attached diff actually have the sysctl set to 0 by
default.

- Use ktr_idx to find the newest entry rather than walking the buffer

  to use getnanotime(9).
- Add a new verbose setting.  When the verbose setting is on, then the
  timestamp is printed with each message.  If KTR_EXTEND is on, then the
  filename and line number are output as well.  By default this option is
  off.  It can be turned on with the 'v' modifier passed to the 'tbuf'
  and 'tall' commands.  For the 'tnext' command, the 'v' modifier toggles
  the verbose mode.

21cd6e6232 - If swap metadata does not fit into the KVM, reduce the number of
struct swblock entries by dividing the number of the entries by 2
until the swap metadata fits.

- Reject swapon(2) upon failure of swap_zone allocation.

This is just a temporary fix. Better solutions include:
(suggested by:	dillon)

o reserving swap in SWAP_META_PAGES chunks, and
o swapping the swblock structures themselves.

6d43764a10 Introduce a new potientially cleaner interface for accessing per-cpu
variables from i386 assembly language.  The syntax is PCPU(member)
where member is the capitalized name of the per-cpu variable, without
the gd_ prefix.  Example: movl %eax,PCPU(CURPROC).  The capitalization
is due to using the offsets generated by genassym rather than the symbols
provided by linking with globals.o.  asmacros.h is the wrong place for
this but it seemed as good a place as any for now.  The old implementation
in asnames.h has not been removed because it is still used to de-mangle
the symbols used by the C variables for the UP case.

1d733bbd10 Preventing runaway kernel soft updates memory, take three.
Previously, the syncer process was the only process in the
system that could process the soft updates background work
list. If enough other processes were adding requests to that
list, it would eventually grow without bound. Because some of
the work list requests require vnodes to be locked, it was
not generally safe to let random processes process the work
list while they already held vnodes locked. By adding a flag
to the work list queue processing function to indicate whether
the calling process could safely lock vnodes, it becomes possible
to co-opt other processes into helping out with the work list.
Now when the worklist gets too large, other processes can safely
help out by picking off those work requests that can be handled
without locking a vnode, leaving only the small number of
requests requiring a vnode lock for the syncer process. With
this change, it appears possible to keep even the nastiest
workloads under control.

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

f786d43aac A bunch of fixes that have been rotting in my tree for a month or two
waiting for procfs to get fixed:

  - Use fill_eproc() to obtain correct VM stats. Attempt to compute VmLib.

  - Fill some more fields in proc/<pid>/stat, and add four (unimplemented)
    fields after studying a recent Linux kernel.

  - Compute CPU frequency only once instead of twice.

  - Fix some comments that were OBE.

  - Fix indentation except where it makes the code less readable.

bb0d0a8efc Next phase in the PCI subsystem cleanup.
- Move PCI core code to dev/pci.
 - Split bridge code out into separate modules.
 - Remove the descriptive strings from the bridge drivers.  If you
   want to know what a device is, use pciconf.  Add support for
   broadly identifying devices based on class/subclass, and for
   parsing a preloaded device identification database so that if
   you want to waste the memory, you can identify *anything* we know
   about.
 - Remove machine-dependant code from the core PCI code.  APIC interrupt
   mapping is performed by shadowing the intline register in machine-
   dependant code.
 - Bring interrupt routing support to the Alpha
   (although many platforms don't yet support routing or mapping
   interrupts entirely correctly).  This resulted in spamming
   <sys/bus.h> into more places than it really should have gone.
 - Put sys/dev on the kernel/modules include path.  This avoids
   having to change *all* the pci*.h includes.

aabafca098 Do not check for existence of ${_dir}/kern/ , because for modules that set
.PATH to ${.CURDIR}/[...]/kern , the "exists" expression will fail for the
form exists(${.CURDIR}/[...]/kern/).  This appears to be happening because
make is searching for the argument to "exists" by using .PATH rather than a
relative search, because .PATH and the argument match at the beginning.
Additionally, make appears to consider a path that starts with ${.CURDIR}
as relative, even though it expands to an absolute path.

The reason that most people aren't seeing this problem is that the absolute
paths of /usr/src/sys and /sys are also searched, so as long as the kernel
source can be found in at least one of those places, no problems surface.
This problem was inadvertently introduced on 1 December 2000, with the
addition of the sysvipc modules.

calling the C functions mtx_enter_hard() and mtx_exit_hard() clobbers them.
Note that %eax is also not call safe, but it is already clobbered due to
cmpxchg.  However, now we are back to not compiling again, so these macros
are still left disabled for now.

0ae554237c - Convert a lot of homebrew debugging output to use the ACPI CA debugging
infrastructure.  It's not perfect, but it's a lot better than what
   we've been using so far.  The following rules apply to this:
    o BSD component names should be capitalised
    o Layer names should be taken from the non-CA set for now.  We
      may elect to add some new BSD-specific layers later.

 - Make it possible to turn off selective debugging flags or layers
   by listing them in debug.acpi.layer or debug.acpi.level prefixed
   with !.

 - Fully implement support for avoiding nodes in the ACPI namespace.
   Nodes may be listed in the debug.acpi.avoid environment variable;
   these nodes and all their children will be ignored (although still
   scanned over) by ACPI functions which scan the namespace.  Multiple
   nodes can be specified, separated by whitespace.

 - Implement support for selectively disabling ACPI subsystem components
   via the debug.acpi.disable environment variable.  The following
   components can be disabled:
    o bus	creation/scanning of the ACPI 'bus'
    o children	attachment of children to the ACPI 'bus'
    o button	the acpi_button control-method button driver
    o ec	the acpi_ec embedded-controller driver
    o isa	acpi replacement of PnP BIOS for ISA device discovery
    o lid	the control-method lid switch driver
    o pci	pci root-bus discovery
    o processor CPU power/speed management
    o thermal	system temperature detection and control
    o timer	ACPI timecounter
   Multiple components may be disabled by specifying their name(s)
   separated by whitespace.

 - Add support for ioctl registration.  ACPI subsystem components may
   register ioctl handlers with the /dev/acpi generic ioctl handler,
   allowing us to avoid the need for a multitude of /dev/acpi* control
   devices, etc.

313231657d Partially re-write T2 chipset support based on Tru64 platform support
files which Compaq open-sourced (with a BSD license).

This commit adds support for proper PCI interrupt mapping and much
better support for swizzling between "standard" isa IRQs and the stdio
irqs used by the t2.  This also adds enabling/disabling/eoi support
for AlphaServer 2100A machines.  The 2100A (or lynx) interrupt
hardware is is very different (and much nicer) than the 2100.
Previously, only AS2100 and AS2000 machines worked.

This commits also lays the groundwork for supporting ExtIO modules.
These modules are essentially a second hose.  This work is left
unfinished pending testing on real hardware.  Wilko tells me that
ExtIO modules are quite rare, and may not actually exist in the wild.

b5861b3450 Really fix phys_pager:
Backout the previous delta (rev 1.4), it didn't make any difference.

If the requested handle is NULL then don't add it to the list of
objects, to be found by handle.

The problem is that when asking for a NULL handle you are implying
you want a new object.  Because objects with NULL handles were
being added to the list, any further requests for phys backed
objects with NULL handles would return a reference to the initial
NULL handle object after finding it on the list.

Basically one couldn't have more than one phys backed object without
a handle in the entire system without this fix.  If you did more
than one shared memory allocation using the phys pager it would
give you your initial allocation again.

look and see if intpin #0 has *no* table entry and adds a fake ExtInt

interrupts.  This entry is only ever used on an already broken system.

their own thread.  Make the legacy schednetisr use an atomic op
for setting bits in the netisr mask.

4d3329891c ACPI HID's aren't limited to 7 characters. Don't check the length of the
HID passed in as an argument at all; callers are typically going to be
sending us static strings anyway.

031fc810ab Initialize/grab the mutex earlier in the attach phase, so that
bailing out to the fail: label where we release/destroy the mutex
will work without exploding.

5ee171d264 Cleanup some leftover lint from the old interrupt system.
Also, while here, run up to 32 interrupt sources on APIC systems.
Normalize INTREN/INTRDIS so they are the same on both UP and SMP systems
rather than sometimes a macro, and sometimes a function.

50088f2089 Turn off the load_eject bit in cdstartunit(). It causes an `Invalid
field in CDB' error when attempting to start a caddy-type CD drive,
since those drives apparently in general refuse to load a medium.  Since
we never advertised the feature to load the medium upon calling
cdstartunit() (i. e. upon receipt of a CDIOCSTART ioctl command), nobody
should have relied on it.  Besides, nobody noticed so far at all that
this command is failing for caddy-type drives...  Only few applications
seem to use it at all (among them is workman, which made me notice it).

b741a1c581 Fix for vanilla PC164 systems to use a slightly different PALcode magic
tweak to enable/disable interrupt sources. Seems to work. It is unclear
how many of the PC164 models actually might needs this, and whether or
not there are other hidden issues.

MPLOCKED macro
(2)	Use decimal 12 rather than hex 0xc in an addl
(3)	Implement MTX_ENTER for the I386_CPU case
(4)	Use semi-colons between instructions to allow MTX_ENTER
	and MTX_ENTER_WITH_RECURSION to be assembled
(5)	Use incl instead of incw to increment the recusion count
(6)	10 is not a valid label, use 7, 8 and 9 rather than 8, 9 and 10
(7)	Sort numeric labels

305501d329 We now have the ability to assign the correct IRQ when PNP-OS is turned
on. So stop failing the attach if the IRQ is unassigned. With this
patch, I can now boot with PNP-OS YES in my BIOS no differently than
PNP-OS NO (which is a good thing since Windows hangs with PNP-OS NO).
