4d6bcc8306 Enable first part of kld's on amd64. This is known to not work right
yet, but building kld's is OK now and they can be loaded by kldload(2).
(but the machine will likely crash soon afterwards, a "minor" problem :-)

e8855d4f97 Make a small revision to the api between the elf linker core and the
elf_reloc() backends for two reasons.  First, to support the possibility
of there being two elf linkers in the kernel (eg: amd64), and second, to
pass the relocbase explicitly (for relocating .o format kld files).

6f8aee2268 Fix a bug which I discovered recently while doing IPv6 testing at
Wind River. In the IPv4 output path, one of the tests in ip_output()
checks how many slots are actually available in the interface output
queue before attempting to send a packet. If, for example, we need
to transmit a packet of 32K bytes over an interface with an MTU of
1500, we know it's going to take about 21 fragments to do it. If
there's less than 21 slots left in the output queue, there's no point
in transmitting anything at all: IP does not do retransmission, so
sending only some of the fragments would just be a waste of bandwidth.
(In an extreme case, if you're sending a heavy stream of fragmented
packets, you might find yourself sending nothing by the first fragment
of all your packets.) So if ip_output() notices there's not enough
room in the output queue to send the frame, it just dumps the packet
and returns ENOBUFS to the app.

It turns out ip6_output() lacks this code. Consequently, this caused
the netperf UDPIPV6_STREAM test to produce very poor results with large
write sizes. This commit adds code to check the remaining space in the
output queue and junk fragmented packets if they're too big to be
sent, just like with IPv4. (I can't imagine anyone's running an NFS
server using UDP over IPv6, but if they are, this will likely make them
a lot happier. :)

92cb9c9b67 Different VIA host bridges use different offsets to their AGP config
registers, so add a register offset array to the softc.  We key off the
device ID to determine which set of register offsets.  Currently the 8385
host bridge used on amd64 is the only bridge to use the AGP3_VIA_*
register offsets and all other bridges use the AGP_VIA_* offsets.  It is
currently unclear if the AGP3_VIA_* offsets are for VIA bridges that
implement AGP 3.0 bridges or just for amd64 bridges.

3335671ddd Split sleepq_wakeup_thread() into two functions. sleepq_remove_thread()
removes a specific thread from a sleep queue.  sleepq_resume_thread()
resumes scheduling of a thread that has been previously removed from a
sleep queue.
- sleepq_catch_signals() just removes a thread from the queue it was just
  added to when a pending signal is found.
- sleepq_signal() and sleepq_broadcast() remove threads from a queue,
  drop the queue lock, and then resume all the previously removed threads.
  This doesn't completely fix the sched_lock <-> sleepq chain LOR, but it
  makes it a little better as we no longer call setrunnble() with a sleep
  queue lock held meaning if setrunnable() tries to wakeup the swapper we
  don't try to lock two sleep queue chains at the same time.

1bb816d3d1 Restructure vm_page_select_cache() so that adding assertions is easy.
Some of the conditions that caused vm_page_select_cache() to deactivate a
page were wrong.  For example, deactivating an unmanaged or wired page is a
nop.  Thus, if vm_page_select_cache() had ever encountered an unmanaged or
wired page, it would have looped forever.  Now, we assert that the page is
neither unmanaged nor wired.

22dbd4c64c aic79xx.c:
Allow 500us between pauses in ahd_pause_and_flushwork().
	The maximum we will wait is now 500ms.

	In the same routine, remove any attempt to clear ENSELO.
	Let the firmware do it once the current selection has
	completed.  This avoids some race conditions having to
	do with non-packetized completions and the auto-clearing
	of ENSELO on packetized completions.

	Also avoid attempts to clear critical sections when
	interrups are pending.  We are going to loop again
	anyway, so clearing critical sections is a waste of
	time.  It also may not be possible to clear a critical
	section if the source of the interrupt was a SEQINT.

aic79xx_pci.c:
	Use the Generic 9005 mask when looking for generic 7901B
	parts.  This allows the driver to attach to 7901B parts
	on motherboards using a non-Adaptec subvendor ID.

aic79xx_inline.h:
	Test for the SCBRAM_RD_BUG against the bugs
	field, not the flags field in the softc.

aic79xx.c:
	Cancel pending transactions on devices that
	respond with a selection timeout.  This decreases
	the duration of timeout recovery when a device
	disappears.

aic79xx.c:
	Don't bother forcing renegotiation on a selection
	timeout now that we use the device reset handler
	to abort any pending commands on the target.
	The device reset handler already takes us down
	to async narrow and forces a renegotiation.

	In the device reset handlers, only send a
	BDR sent async event if the status is not
	CAM_SEL_TIMEOUT.  This avoids sending this
	event in the selection timeout case

aic79xx.c:
	Modify the Core timeout handler to verify that another
	command has the potential to timeout before passing off
	a command timeout as due to some other command.  This
	safety measure is added in response to a timeout recovery
	failure on H2B where it appears that incoming reselection
	status was lost during a drive pull test.  In that case,
	the recovery handler continued to wait for the command
	that was active on the bus indefinetly.  While the root
	cause of the above issue is still being determined seems
	a prudent safeguard.

aic79xx_pci.c:
	Add a specific probe entry for the Dell OEM 39320(B).

aic79xx.c:
aic79xx.h:
aic79xx.reg:
aic79xx.seq:
	Modify the aic79xx firmware to never cross a cacheline or
	ADB boundary when DMA'ing completion entries to the host.
	In PCI mode, at least in 32/33 configurations, the SCB
	DMA engine may lose its place in the data-stream should
	the target force a retry on something other than an
	8byte aligned boundary. In PCI-X mode, we do this to
	avoid split transactions since many chipsets seem to be
	unable to format proper split completions to continue
	the data transfer.

	The above change allows us to drop our completion entries
	from 8 bytes to 4.  We were using 8 byte entries to ensure
	that PCI retries could only occur on an 8byte aligned
	boundary.  Now that the sequencer guarantees this by splitting
	up completions, we can safely drop the size to 4 bytes (2
	byte tag, one byte SG_RESID, one byte pad).

	Both the split-completion and PCI retry problems only show
	up under high tag load when interrupt coalescing is being
	especially effective.  The switch from a 2byte completion
	entry to an 8 byte entry to solve the PCI problem increased
	the chance of incurring a split in PCI-X mode when multiple
	transactions were completed at once.  Dropping the completion
	size to 4 bytes also means that we can complete more commands
	in a single DMA (128byte FIFO -> 32 commands instead of 16).

aic79xx.c:
	Modify the SCSIINT handler to defer clearing
	sequencer critical sections to the individual
	interrupt handlers.  This allows us to
	immediately disable any outgoing selections in
	the case of an unexpected busfree so we don't
	inadvertantly clear ENSELO *after* a new selection
	has started.  Doing so may cause the sequencer
	to miss a successful selection.

	In ahd_update_pending_scbs(), only clear ENSELO if
	the bus is currently busy and a selection is not
	already in progress or the sequencer has yet to
	handle a pending selection.  While we want to ensure
	that the selection for the SCB at the head of the
	selection queue is restarted so that any change in
	negotiation request can take effect, we can't clobber
	pending selection state without confusing the sequencer
	into missing a selection.

f49574218d o When restarting the sequencer, clear any pending
sequencer interrupt codes.  These codes are only
  relevant to the code that was last being executed
  and that context is cleared when we reset the
  program counter.  This addresses a race condition
  between a sequencer interrupt and any SCSI event
  that causes us to restart the sequencer.

o When running the untagged-Q, we must start the
  timer for any transaction we queue.

o Give the firmware half a millisecond between
  pauses to flush work out.  This should give us
  around half a second of total delay before flagging
  an issue with pausing and flushing controller work.

  Only attempt to clear critical sections if there
  are no pending interrupts in the pause and flush
  loop.  If the sequencer has issued an INTSTAT, we
  may not be able to step out of the critical section.

o Cancel pending transactions on devices that
  respond with a selection timeout.  This decreases
  the duration of timeout recovery when a device
  disappears.

  Don't bother forcing renegotiation on a selection

eb8943b13e Rework the APIC mixed mode support a bit:
- Require the APIC enumerators to explicitly enable mixed mode by calling
  ioapic_enable_mixed_mode().  Calling this function tells the apic driver
  that the PC-AT 8259A PICs are present and routable through the first I/O
  APIC via an ExtINT pin.  The mptable enumerator always calls this
  function for now.  The MADT enumerator only enables mixed mode if the
  PC-AT compatability flag is set in the MADT header.
- Allow mixed mode to be enabled or disabled via a 'hw.apic.mixed_mode'
  tunable.  By default this tunable is set to 1 (true).  The kernel option
  NO_MIXED_MODE changes the default to 0 to preserve existing behavior, but
  adding 'hw.apic.mixed_mode=0' to loader.conf achieves the same effect.
- Only use mixed mode to route IRQ 0 if it is both enabled by the APIC
  enumerator and activated by the loader tunable.  Note that both
  conditions must be true, so if the APIC enumerator does not enable mixed
  mode, then you can't set the tunable to try to override the enumerator.

0fd166d7da - Change madt_map_table() to verify the checksum of any table it is asked
to map.  If the checksum fails, the table is unmapped and a NULL pointer
  returned.
- For ACPI version >= 2.0, check the extended checksum of the RSDP.
  AcpiOsGetRootPointer() already checks the version 1.0 checksum.
- Remap the full MADT table at the end of madt_probe() so that we verify
  its checksum before saying it is really there.

fb0ac5433b If an ACPI PCI-PCI bridge doesn't have a _PRT object, fall back to using
the swizzle method for routing PCI interrupts across the bridge.  This
fixes problems with motherboards (typically laptops) whose BIOS doesn't
provide a PRT for the AGP bridge even though there is a device entry for
the bridge in the ACPI namespace.

3581cc66bb Zero the un-used portions of the struct sockaddr data before sending
it back to userspace, so it does not break bind(2) on raw sockets in jails.

Currently some processes, like traceroute(8) construct a routing request
to determine its source address based on the destination. This sockaddr
data is fed directly to bind(2). When bind calls ifa_ifwithaddr(9) to
make sure the address exists on the interface, the comparison will
fail causing bind(2) to return EADDRNOTAVAIL if the data wasnt zero'ed
before initialization.

when we decide what form our priority extensions will take. Posix doesn't

fbfb97942e It turns out that the module dependency on pccard is in error. Since
there's not dependencies on pccard symboles, such a dependency is not
necessary.  This means that drivers that have multiple attachments can
not drag bogus devices into the kernel at load time.

We can't (yet) do this with pci and isa.  Drivers written for them
actually do seem to have symbols that depend on these busses'
implementation code.

af7cd0c521 Properly remove MAP_FUTUREWIRE when a vm_map_entry gets torn down.
Previously, mlockall(2) usage would leak MAP_FUTUREWIRE of the process's
vmspace::vm_map and subsequent processes would wire all of their memory.
Coupled with a wired-page leak in vm_fault_unwire(), this would run the
system out of free pages and cause programs to randomly SIGBUS when
faulting in new pages.

(Note that this is not the fix for the latter part; pages are still
 leaked when a wired area is unmapped in some cases.)

that the OHCI driver uses.  Broken OHCI devices (like the controller
in my laptop, apparently) like to set this bit at times.  Research
through google shows that this problem has shown up on other systems
as well.

As the scheduling overrun handler doesn't actually do anything, and
the only effect is console spamming, disabling the interrupt seems
to be the right thing to do.  (And it is also what linux 2.6 does.)

allocation.  For such cases, clearing the flag is pointless.  The only
unusual use of PG_ZERO is in vfs_bio_clrbuf().  However, allocbuf() never
requests a prezeroed page.  So, vfs_bio_clrbuf() never sees a prezeroed
page.

- Make pci_pir_parse() private to pci_pir.c and have pir0's attach routine
  call it instead of having legacy_pcib_attach() call it.
- Implement suspend/resume support for the $PIR by giving pir0 a resume
  method that calls the BIOS to reroute each link that was already routed
  before the machine was suspended.
- Dump the state of the routed flag in the links display code.
- If a link's IRQ is set by a tunable, then force that link to be re-routed
  the first time it is used.
- Move the 'Found $PIR' message under bootverbose as the pir0 description
  line lists the number of entries already.  The pir0 line also only shows
  up if we are actually using the $PIR which is a bonus.
- Use BUS_CONFIG_INTR() to ensure that any IRQs used by a PCI link are
  set to level/low trigger/polarity.

635af77a22 Have ACPI use BUS_CONFIG_INTR() to force the SCI to level trigger and
active low polarity when using the PIC interrupt model.  This should fix
broken SCI interrupts on machines when not using the APIC where the BIOS
doesn't program the ELCR to level trigger for the ACPI SCI.

4b1df14c60 - Add a new pic method pic_config_intr() to set the trigger mode and
polarity for a specified IRQ.  The intr_config_intr() function wraps
  this pic method hiding the IRQ to interrupt source lookup.
- Add a config_intr() method to the atpic(4) driver that reconfigures
  the interrupt using the ELCR if possible and returns an error otherwise.
- Add a config_intr() method to the apic(4) driver that just logs any
  requests that would change the existing programming under bootverbose.
  Currently, the only changes the apic(4) driver receives are due to bugs
  in the acpi(4) driver and its handling of link devices, hence the reason
  for such requests currently being ignored.
- Have the nexus(4) driver on i386 implement the bus_config_intr() function
  by calling intr_config_intr().

c2ce35977e - Change the APIC code to mostly use the recently added intr_trigger
and intr_polarity enums for passing around interrupt trigger modes and
  polarity rather than using the magic numbers 0 for level/low and 1 for
  edge/high.
- Convert the mptable parsing code to use the new ELCR wrapper code rather
  than reading the ELCR directly.  Also, use the ELCR settings to control
  both the trigger and polarity of EISA IRQs instead of just the trigger
  mode.
- Rework the MADT's handling of the ACPI SCI again:
  - If no override entry for the SCI exists at all, use level/low trigger
    instead of the default edge/high used for ISA IRQs.
  - For the ACPI SCI, use level/low values for conforming trigger and
    polarity rather than the edge/high values we use for all other ISA
    IRQs.
  - Rework the tunables available to override the MADT.  The
    hw.acpi.force_sci_lo tunable is no longer supported.  Instead, there
    are now two tunables that can independently override the trigger mode
    and/or polarity of the SCI.  The hw.acpi.sci.trigger tunable can be
    set to either "edge" or "level", and the hw.acpi.sci.polarity tunable
    can be set to either "high" or "low".  To simulate hw.acpi.force_sci_lo,
    set hw.acpi.sci.trigger to "level" and hw.acpi.sci.polarity to "low".
    If you are having problems with ACPI either causing an interrupt storm
    or not working at all (e.g., the power button doesn't turn invoke a
    shutdown -p now), you can try tweaking these two tunables to find the
    combination that works.

7e4af296b3 - Add a member to the atpic interrupt source structures to indicate if the
IRQ is edge triggered or level triggered.  For ISA interrupts, we assume
  that edge triggered interrupts are always active high and that level
  triggered interrupts are always active low.
- Don't disable an edge triggered interrupt in the PIC.  This avoids
  outb instructions to the actual PIC for traditional ISA IRQs such as
  IRQ 1, 6, 14, and 15.  (Fast interrupts such as IRQs 0 and 8 don't mask
  their source, so this doesn't change anything for them.)
- For MCA systems we assume that all interrupts are level triggered and
  thus need masking.  Otherwise, we probe the ELCR.  If it exists we trust
  what it tells us regarding which interrupts are level triggered.  If it
  does not exist, we assume that IRQs 0, 1, 2, and 8 are edge triggered
  and that all other IRQs are level triggered and need masking.
- Instruct the ELCR mini-driver to restore its saved state during resume.

030b156bf0 Add a simple mini-driver for the ELCR register. Originally, the ELCR
register controlled the trigger mode and polarity of EISA interrupts.
However, it appears that most (all?) PCI systems use the ELCR to manage
the trigger mode and polarity of ISA interrupts as well since ISA IRQs used
to route PCI interrupts need to be level triggered with active low
polarity.  We check to see if the ELCR exists by sanity checking the value
we get back ensuring that IRQS 0 (8254), 1 (atkbd), 2 (the link from the
slave PIC), and 8 (RTC) are all clear indicating edge trigger and active
high polarity.

This mini-driver will be used by the atpic driver to manage the trigger and
polarity of ISA IRQs.  Also, the mptable parsing code will use this mini
driver rather than examining the ELCR directly.

eced428604 Fix hangs caused by z8530_bus_ipend() returning UART_IPEND_TXIDLE
not as a pending interrupt status, but as a matter of status quo.
Consequently, when there's no data to be transmitted the condition
is not cleared and uart_intr() is stuck in an infinite loop trying
to clear the UART_IPEND_TXIDLE status.
The z8530_bus_ipend() function is changed to return idle only once
after having sent any data.

The root cause for this problem is that we cannot use the interrupt
status bits of the SCC itself. The register that holds the interrupt
status can only be accessed by channel A and holds the status for
both channels. Using the interrupt status register would complicate
the driver because we need to synchronize access to the SCC between
the channels.

c18b97c630 Switch to using the inpcb MAC label instead of socket MAC label when
labeling new mbufs created from sockets/inpcbs in IPv4.  This helps avoid
the need for socket layer locking in the lower level network paths
where inpcb locks are already frequently held where needed.  In
particular:

- Use the inpcb for label instead of socket in raw_append().
- Use the inpcb for label instead of socket in tcp_output().
- Use the inpcb for label instead of socket in tcp_respond().
- Use the inpcb for label instead of socket in tcp_twrespond().
- Use the inpcb for label instead of socket in syncache_respond().

While here, modify tcp_respond() to avoid assigning NULL to a stack
variable and centralize assertions about the inpcb when inp is
assigned.

583284e1d7 If the mbuf pointer passed to mac_mbuf_to_label() is NULL, or the tag
lookup for the label tag fails, return NULL rather than something close
to NULL.  This scenario occurs if mbuf header labeling is optional and
a policy requiring labeling is loaded, resulting in some mbufs having
labels and others not.  Previously, 0x14 would be returned because the
NULL from m_tag_find() was not treated specially.

o New function ip_findroute() to reduce code duplication for the

o Store ip_len in host byte order on the stack instead of using
  it via indirection from the mbuf.  This allows to defer the host
  byte conversion to a later point and makes a quicker fallback to
  normal ip_input() processing. (luigi)

o Check if route is dampned with RTF_REJECT flag and drop packet
  already here when ARP is unable to resolve destination address.
  An ICMP unreachable is sent to inform the sender.

o Check if interface output queue is full and drop packet already
  here.  No ICMP notification is sent because signalling source quench
  is depreciated.

o Check if media_state is down (used for ethernet type interfaces)
  and drop the packet already here.  An ICMP unreachable is sent to
  inform the sender.

o Do not account sent packets to the interface address counters.  They
  are only for packets with that 'ia' as source address.
