55deb20670 It is next year in Asia already, so jump the gun a little and commit
the year bump.

# If we behaved like book publishers, we'd do this in July.  I can't find
# a good reference for why they do it then, but it has been explained to
# me that copyrights in the last 1/2 of the year expire as if they were
# published in the following year.  I can't confirm this info, but if you
# have a pointer, please send it to me.

ef39c05baa MI changes:
- provide an interface (macros) to the page coloring part of the VM system,
   this allows to try different coloring algorithms without the need to
   touch every file [1]
 - make the page queue tuning values readable: sysctl vm.stats.pagequeue
 - autotuning of the page coloring values based upon the cache size instead
   of options in the kernel config (disabling of the page coloring as a
   kernel option is still possible)

MD changes:
 - detection of the cache size: only IA32 and AMD64 (untested) contains
   cache size detection code, every other arch just comes with a dummy
   function (this results in the use of default values like it was the
   case without the autotuning of the page coloring)
 - print some more info on Intel CPU's (like we do on AMD and Transmeta
   CPU's)

Note to AMD owners (IA32 and AMD64): please run "sysctl vm.stats.pagequeue"
and report if the cache* values are zero (= bug in the cache detection code)
or not.

571e4e6285 Introduce a new sysctl variable:
security.mac.biba.interfaces_equal

If non-zero, all network interfaces be created with the label:

biba/equal(equal-equal)

This is useful where programs which initialize network interfaces
do not have any labeling support. This includes dhclient and ppp. A
long term solution is to add labeling support into dhclient(8)
and ppp(8), and remove this variable.

It should be noted that this behavior is different then setting the:

security.mac.biba.trust_all_interfaces

sysctl variable, as this will create interfaces with a biba/high label.
Lower integrity processes are not able to write to the interface in this
event. The security.mac.biba.interfaces_equal will override
trust_all_interfaces.

The security.mac.biba.interfaces_equal variable will be set to zero
or disabled by default.

a9883bc8c4 Expose pci_add_resources to the outside world, add a 'force' flag to
force allocation of unallocated BARs (cardbus uses this to preallocate
everything).  Add a prefetchmask to allow for busses that get prefetch
hints to set them.  Addjust pci_add_map and pci_ata_maps to take a new
force flag which pci_add_resources will pass in.  Implement 'force' in
pci_add_map.  Write new value of allocated resource into the bar, if
the allocation succeeded (we should have done this before, but with
the new force the bug was very obvious).

d362c40d3a Improve memguard a bit:
- Provide tunable vm.memguard.desc, so one can specify memory type without
  changing the code and recompiling the kernel.
- Allow to use memguard for kernel modules by providing sysctl
  vm.memguard.desc, which can be changed to short description of memory
  type before module is loaded.
- Move as much memguard code as possible to memguard.c.
- Add sysctl node vm.memguard. and move memguard-specific sysctl there.
- Add malloc_desc2type() function for finding memory type based on its
  short description (ks_shortdesc field).
- Memory type can be changed (via vm.memguard.desc sysctl) only if it
  doesn't exist (will be loaded later) or when no memory is allocated yet.
  If there is allocated memory for the given memory type, return EBUSY.
- Implement two ways of memory types comparsion and make safer/slower the
  default.

3ac604874c Simplify the opening of the resources for cardbus cards. Before we'd
try very hard to be perfect.  However, these attempts broke down when
there were large numbers of resources.  We'd not be able to map them all.

Instead, accept that we might pass more range to thse subbus than
might be optimal be able to compute.  However, there's little harm in
this and it allows us to pass greater resources through.

# it has been suggested that we allocate a fixed amount of resources
# on attach and give it out upon request.  This might not be a bad idea...

0cb7e6aec8 Add a new function msleep_spin() which is a slightly stripped down version
of msleep().  msleep_spin() doesn't support changing the priority of the
thread while it is asleep nor does it support interruptible sleeps (PCATCH)
or the PDROP flag.  It does support timeouts however.  It differs from
msleep() in that the passed in mutex is a spin mutex.  This means one can
use msleep_spin() and wakeup() with a spin mutex similar to msleep() and
wakeup() with a regular mutex.  Note that the spin mutex in question needs
to come before sched_lock and the sleepq locks in lock order.

0a46ed7d56 Fix a deadlock I introduced with the recently added printf to warn about
spin locks that are not in the static order list.  It is not safe to call
printf while holding the witness spin mutex since the console drivers that
back printf may need to use their own spin locks which would try to talk
to witness when they were locked.  Given this, it is possible for one
CPU to lock a console driver lock (such as sio) which then tries to lock
the witness lock while another CPU is doing the printf while holding the
witness lock.  Fix this by moving the printf outside of the witness lock.
All other printf's in witness are already correct.

9190333ce7 Fix the order of the stereo channels (left <-> right).
From the PR:
---snip---
 I think I have found the change which reversed the channels.
 Revision 1.44 of emu10k1.c, which added Audigy support, has the line

 emu_wrptr(sc, v->vnum, FXRT, 0xd01c0000);

 replaced with the following lines:

 if (sc->audigy) {
         emu_wrptr(sc, v->vnum, A_FXRT1, v->fxrt1);
         emu_wrptr(sc, v->vnum, A_FXRT2, v->fxrt2);
         emu_wrptr(sc, v->vnum, A_SENDAMOUNTS, 0);
 }
 else
         emu_wrptr(sc, v->vnum, FXRT, v->fxrt1 << 16);

 where v->fxrt1 << 16 == 0xd10c0000

 I don't have Audigy, so I'm not sure if the problem affects Audigy cards
 too. The order of the channels can't be tested by just altering mixer
 settings. Here's a small program to test if the channels are reversed on
 your sound card:

     48, 193, 0, 0, 247, 207, 0, 0, 136, 223, 0, 0, 162, 239, 0, 0};

   ioctl(fd, SNDCTL_DSP_SETFMT,&format);
   ioctl(fd, SNDCTL_DSP_CHANNELS,&channels);
   ioctl(fd, SNDCTL_DSP_SPEED,&rate);

   for(i=0;i<500;i++)
     write(fd, &samples, sizeof(samples));
   write(fd, &samples, 2); /* swap channels */
   for(i=0;i<500;i++)
     write(fd, &samples, sizeof(samples));

   return 0;
 }

 You should hear a sound on the left channel followed by a sound on the
 right channel. If you hear a sound on the right channel first, the
 channels are reversed.

086745614c When in rev. 1.47 cardbus_alloc_resources() function was moved from
cardbus_cis.c to this file, some code was not merged and thus resource
list entries were invalid. They didn't have a resources attached to
them.
  However, the problem was masked for some time later, because newer
resources list entries were added to the head of the list, and
resource_list_find() always returned the first matching resource list
entry. Usually the underlying driver allocated a valid resource and
added it to the head of the list, and invalid one wasn't used.
  In rev. 1.174 of subr_bus.c the sorting of resource list entries was
reversed demasking the problem in cardbus_alloc_resources().
  This commit fixes the problem returning back some code from
cardbus_cis.c, pre-1.49 revisions.

d54c905707 Bring big-endian architecture support for ti(4).
. remove unnecessay header files after Scott's bus_dma(9) commit.
 . remove global variable tis which was introduced at the time of
   zero_copy(9) changes. The variable tis was not used at all. The
   same applyes to ti_links in softc so axe it.
 . deregister variables.
 . axe ti_vhandle and switch to use explicit register access for
   accessing NIC local memory. Creates three variants of ti_mem to
   read/write NIC local memory(ti_mem_read, ti_mem_write) and clearing
   NIC local memory(ti_mem_zero). This greatly enhances code
   readability and have ti(4) drop using shared memory scheme for
   Tigon 1. As Tigon 1 switched to use explicit register access for Tx,
   axe ti_tx_ring_nic/ti_cmd_ring in softc.(Tigon 2 used to host ring
   scheme which means there is no need to access NIC local memory via
   register access for Tx and NIC would DMA the modified Tx rings into
   its local memory.) [1]
 . introduce new macro TI_EVENT_*/TI_CMD_* to handle NIC envent/command.
   Instead of using bit fields assginment for accessing the event, use
   shift operations to set/get it. [1]
 . add additional check for valid DMA tags in ti_free_dmamaps().
 . add missing bus_dmamap_sync/bus_dmamap_unload in ti_free_*_ring_*.
 . fix locking nits(MTX_RECURSE mutex) and make ti(4) MPSAFE.
 . change data type of ti_rdata_phys to bus_addr_t and don't blindly
   cast to uint32_t.
 . rearrange detach path and make ti(4) survive during device detach.
 . for Tigon 1, use explicit register access for checking Tx descriptors
   in ti_encap()/ti_txeof(). [1]
 . properly call bus_dmamap_sync(9) for updating statistics.
 . remove extra semicolon in ti_encap()
 . rewrite loading MAC address to work on strict-alignment architectures.
 . move TI_RD_OFF macro to if_tireg.h
 . axe ETHER_ALIGN as it's already defined in <net/ethernet.h>.
 . make macros immuine from expansion by adding parenthesis and do-while.
 . remove alpha specific hack as vtophys(9) is no longer used in ti(4)
   after Scott's bus_dma(9) fix.

619f284195 In realloc(9), determine size of the original block based on
UMA_SLAB_MALLOC flag.
In some circumstances (I observed it when I was doing a lot of reallocs)
UMA_SLAB_MALLOC can be set even if us_keg != NULL.

If this is the case we have wonderful, silent data corruption, because less
data is copied to the newly allocated region than should be.

I'm not sure when this bug was introduced, it could be there undetected
for years now, as we don't have a lot of realloc(9) consumers and it was
hard to reproduce it...
...but what I know for sure, is that I don't want to know who introduce

b439e431bf Tweak how the MD code calls the fooclock() methods some. Instead of
passing a pointer to an opaque clockframe structure and requiring the
MD code to supply CLKF_FOO() macros to extract needed values out of the
opaque structure, just pass the needed values directly.  In practice this
means passing the pair (usermode, pc) to hardclock() and profclock() and
passing the boolean (usermode) to hardclock_cpu() and hardclock_process().
Other details:
- Axe clockframe and CLKF_FOO() macros on all architectures.  Basically,
  all the archs were taking a trapframe and converting it into a clockframe
  one way or another.  Now they can just extract the PC and usermode values
  directly out of the trapframe and pass it to fooclock().
- Renamed hardclock_process() to hardclock_cpu() as the latter is more
  accurate.
- On Alpha, we now run profclock() at hz (profhz == hz) rather than at
  the slower stathz.
- On Alpha, for the TurboLaser machines that don't have an 8254
  timecounter, call hardclock() directly.  This removes an extra
  conditional check from every clock interrupt on Alpha on the BSP.
  There is probably room for even further pruning here by changing Alpha
  to use the simplified timecounter we use on x86 with the lapic timer
  since we don't get interrupts from the 8254 on Alpha anyway.
- On x86, clkintr() shouldn't ever be called now unless using_lapic_timer
  is false, so add a KASSERT() to that affect and remove a condition
  to slightly optimize the non-lapic case.
- Change prototypeof  arm_handler_execute() so that it's first arg is a
  trapframe pointer rather than a void pointer for clarity.
- Use KCOUNT macro in profclock() to lookup the kernel profiling bucket.

 - added missing bus_dmamap_sync(9) in bge_txeof().
 - added missing bus_dmamap_sync(9) in bge_encap().
 - corrected memory synchronization operation on status block.
   As the driver just read status block that was DMAed by NIC it
   should use BUS_DMASYNC_POSTREAD. Likewise the driver does not
   need to write status block back, so remove unnecessary
   bus_dmamap_sync(9) calls in bge_intr().
 - corrected memory synchronization operation on RX return ring.
   The driver only read the block so remove unnecessary
   bus_dmamap_sync(9) in bge_rxeof().
 - force bus_dmamap_sync(9) for only modified descriptors. Blindly

c626f1fe9a Change the various AGP drivers that attach to the Host-PCI bridge device to
attach to the hostb driver instead.  This means that agp can now be loaded
at runtime (in theory at least).  Also, the drivers no longer have to
explicity call device_verbose() to cancel out any earlier calls to
device_quiet() by the hostb(4) driver (this shows a limitation in new-bus,
drivers really shouldn't be doing device_quiet() until they know they are
going to drive that device, i.e. in attach).

memory directly available to loader(8) and friends was limited to 640K on i386.
Those times have passed long time ago and now loader(8) can directly access

places where it's assumed that malloc() will only allocate memory within
first megabyte.

Remove that assumption by allocating appropriate bounce buffers for BIOS
calls on stack where necessary.

This allows using memory above first megabyte for heap if necessary.

da61b9a69e Use sf_buf_alloc() instead of vm_map_find() on exec_map to create the
ephemeral mappings that are used as the source for three copy
operations from kernel space to user space.  There are two reasons for
making this change: (1) Under heavy load exec_map can fill up causing
vm_map_find() to fail.  When it fails, the nascent process is aborted
(SIGABRT).  Whereas, this reimplementation using sf_buf_alloc()
sleeps.  (2) Although it is possible to sleep on vm_map_find()'s
failure until address space becomes available (see kmem_alloc_wait()),
using sf_buf_alloc() is faster.  Furthermore, the reimplementation
uses a CPU private mapping, avoiding a TLB shootdown on
multiprocessors.

1a40739a00 Fix PCI ID of the AMD-8111 System Management controller so it matches
SMBus 1.0 and not SMBus 2.0.

AMD-8111 hub (datasheet is publically available) implements both SMBus
2.0 (a separate PCI device) and SMBus 1.0 (a subfunction of the System
Management Controller device with the base I/O address is accessible
through the CSR 0x58).  This driver only supports AMD-756 SMBus 1.0
compatible devices.

With the patched sysutils/xmbmon port (to also fix PCI ID and to enable
smb(4) support), I now get:

pciconf:
none0@pci0:7:2: class=0x0c0500 card=0x746a1022 chip=0x746a1022 rev=0x02 hdr=0x00

    vendor   = 'Advanced Micro Devices (AMD)'
    device   = 'AMD-8111 ACPI System Management Controller'
    class    = bridge

dmesg:

# mbmon -A -d
Summary of Detection:

  ** Analog Dev. Chip ADM1027 found at slave address: 0x5C.
 * ISA monitor(s):
  ** Winbond Chip W83627HF/THF/THF-A found.

I think the confusion comes from the fact that nobody really tried
SMBus with xmbmon :-), since sysutils/xmbmon port doesn't come with
SMBus support enabled, neither in FreeBSD 4, nor in later versions,
so mbmon(1) was just showing the values from the Winbond sensors
accessible through the ISA I/O method (mbmon -I), for me anyway.

On my test machine, the amdpm(4) didn't even attach due to I/O port
allocation failure (who knows what the hell it read from CSR 0x58
of the SMBus 2.0 device :-), which isn't in the CSR space).

I've also checked that lm_sensors.org uses correct PCI ID for SMBus
1.0 of AMD-8111:

i2c-amd756.c:   {PCI_VENDOR_ID_AMD, 0x746B, PCI_ANY_ID, PCI_ANY_ID, 0, 0, AMD8111 },

This driver is analogous to our amdpm.c which supports SMBus 1.0
AMD-756 and compatible devices, including SMBus 1.0 on AMD-8111.

i2c-amd8111.c:  { 0x1022, 0x746a, PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0 },

This driver is analogous to nForce-2/3/4, i2c-nforce2.c, which
supports SMBus 2.0, and which our amdpm.c does NOT support
(SMBus 2.0 uses a different, ACPI-unified, API to talk to SMBus).
At least I know for sure it doesn't work with my nForce3.  :-)

(The xmbmon port will be fixed to correct the PCI ID too and to
enable the smb(4) support.)

e907febf6a Add bge(4) support for big-endian architectures(part 1/2).
- Give up endianess support and switch to native-endian format for
   accessing hardware structures. In fact embedded processor for
   BCM57xx is big-endian architure(MIPS) and it requires native-endian
   format for NIC structures.The NIC performs necessary byte/word
   swapping depending on programmed endian type.
 - With above changes all htole16/htole32 calls were gone.
 - Remove bge_vhandle member in softc and changed to use explicit
   register access. This may add additional performance penalty
   that than that of previous memory access. But most of the access
   is performed on initialization phase(e.g. RCB setup), it would be
   negligible.

Due to incorrect use of bus_dma(9) in bge(4) it still panics sparc64
system in device detach path. The issue would be fixed in next patch.

5351742ea2 Mega update to the LSI MegaRAID driver:
1.  Implement a large set of ioctl shims so that the Linux management apps
from LSI will work.  This includes infrastructure to support adding, deleting
and rescanning arrays at runtime.  This is based on work from Doug Ambrosko,
heavily augmented by LSI and Yahoo.

2.  Implement full 64-bit DMA support.  Systems with more than 4GB of RAM
can now operate without the cost of bounce buffers.  Cards that cannot do
64-bit DMA will automatically revert to using bounce buffers.  This option
can be forced off by setting the 'hw.amr.force_sg32" tunable in the loader.
It should only be turned off for debugging purposes.  This work was sponsored
by Yahoo.

3.  Streamline the command delivery and interrupt handler paths after
much discussion with Dell and LSI.  The logic now closely matches the
intended design, making it both more robust and much faster.  Certain
i/o failures under heavy load should be fixed with this.

4.  Optimize the locking.  In the interrupt handler, the card can be checked
for completed commands without any locks held, due to the handler being
implicitely serialized and there being no need to look at any shared data.
Only grab the lock to return the command structure to the free pool.  A
small optimization can still be made to collect all of the completions
together and then free them together under a single lock.

Items 3 and 4 significantly increase the performance of the driver.  On an
LSI 320-2X card, transactions per second went from 13,000 to 31,000 in my
testing with these changes.  However, these changes are still fairly
experimental and shouldn't be merged to 6.x until there is more testing.

Thanks to Doug Ambrosko, LSI, Dell, and Yahoo for contributing towards
this.

6239708b1c Fix the Tigon I/II driver to support 64-bit DMA. In the process, convert it
to use busdma.  Unlike most of the other drivers, but similar to the
if_em driver, pre-allocate the dmamaps at init time instead of allocating
them on the fly when descriptors need to be filled.  This isn't ideal right
now because a map is allocated for every descriptor slot in the tx, rx, mini,
and jumbo rings (which is a lot!) in order to simplify the bookkeeping, even
though the driver might support filling only a subset of those slots.
Luckily, maps are typically NULL on i386 and amd64, so the cost isn't
very high.  It could be an issue with sparc64, but the driver isn't endian
clean either, and that is a much bigger problem to solve first.

Note that jumbo frame support is under-tested, and I'm not even sure if
it till really works correctly given the evil VM magic that is does.
The changes here attempt to preserve the existing semanitcs.

Thanks to Martin Nillson for contributing the Netgear card for this work.

d272fe53a4 Add a new 'show lock' command to ddb. If the argument has a valid lock
class, then it displays various information about the lock and calls a
new function pointer in lock_class (lc_ddb_show) to dump class-specific
information about the lock as well (such as the owner of a mutex or
xlock'ed sx lock).  This is easier than staring at hex dumps of locks to
figure out who owns the lock, etc.  Note that extending lock_class doesn't
affect the ABI for any kernel modules as the only code that deals with
lock_class structures directly is kern_mutex.c, kern_sx.c, and witness.

15b7edbeaa Don't check the CPUID_APIC bit in the cpu_features flags field to determine
if the boot CPU has a local APIC because some BIOS vendors are not
competent enough to set this bit.  Instead, just assume that we always have
a local APIC on amd64.  For i386 the check is a bit more subtle.  FreeBSD
requires either an MP Table or an ACPI MADT table to enumerate APICs.  The
only systems that have one of those tables that don't have local APICs are
some presumably rare (and old) SMP 486 systems using external APICs.  Thus,
instead of checking the CPUID_APIC flag, check the CPU class and abort if
we are running on a 486.

40b1ae9e00 Add a new feature for optimizining ipfw rulesets - substitution of the
action argument with the value obtained from table lookup. The feature
is now applicable only to "pipe", "queue", "divert", "tee", "netgraph"
and "ngtee" rules.

An example usage:

  ipfw pipe 1000 config bw 1000Kbyte/s
  ipfw pipe 4000 config bw 4000Kbyte/s
  ipfw table 1 add x.x.x.x 1000
  ipfw table 1 add x.x.x.y 4000
  ipfw pipe tablearg ip from table(1) to any

In the example above the rule will throw different packets to different pipes.

TODO:
  - Support "skipto" action, but without searching all rules.
  - Improve parser, so that it warns about bad rules. These are:
    - "tablearg" argument to action, but no "table" in the rule. All
      traffic will be blocked.
    - "tablearg" argument to action, but "table" searches for entry with
      a specific value. All traffic will be blocked.
    - "tablearg" argument to action, and two "table" looks - for src and
      for dst. The last lookup will match.
