8194412b89 Add support for using uart(4) for pulse capturing for the Pulse Per
Second (PPS) timing interface. The support is non-optional and by
default uses the DCD line signal as the pulse input. A compile-time
option (UART_PPS_ON_CTS) can be used to have uart(4) use the CTS line
signal.

Include <sys/timepps.h> in uart_bus.h to avoid having to add the
inclusion of that header in all source files.

9bac70b851 Add a PHY driver to support the built-in gigE PHY in the 8169S/8110S
ethernet chips. This driver is pretty simple, however it contains
special DSP initialization code which is needed in order to get
the chip to negotiate a gigE link. (This special initialization
may not be needed in subsequent chip revs.) Also:

- Fix typo in if_rlreg.h (RL_GMEDIASTAT_1000MPS -> RL_GMEDIASTAT_1000MBPS)

- Deal with shared interrupts in re_intr(): if interface isn't up,
  return.

- Fix another bug in re_gmii_writereg() (properly apply data field mask)

- Allow PHY driver to read the RL_GMEDIASTAT register via the
  re_gmii_readreg() register (this is register needed to determine
  real time link/media status).

b9f78d2b4a Add a device driver for the Broadcom BCM4401 ethernet controller,
written by Stuart Walsh and Duncan Barclay (with some kibbitzing by
me). I'm checking it in on Stuart's behalf.

The BCM4401 is built into several x86 laptop and desktop systems. For the
moment, I have only enabled it in the x86 kernel config because although
it's a PCI device, I haven't heard of any standalone NICs that use it. If
somebody knows of one, we can easily add it to the other arches.

This driver uses register/structure data gleaned from the Linux
driver released by Broadcom, but does not contain any of the code
from the Linux driver itself. It uses busdma.

a94100fa9b Take the support for the 8139C+/8169/8169S/8110S chips out of the
rl(4) driver and put it in a new re(4) driver. The re(4) driver shares
the if_rlreg.h file with rl(4) but is a separate module. (Ultimately
I may change this. For now, it's convenient.)

rl(4) has been modified so that it will never attach to an 8139C+
chip, leaving it to re(4) instead. Only re(4) has the PCI IDs to
match the 8169/8169S/8110S gigE chips. if_re.c contains the same
basic code that was originally bolted onto if_rl.c, with the
following updates:

- Added support for jumbo frames. Currently, there seems to be
  a limit of approximately 6200 bytes for jumbo frames on transmit.
  (This was determined via experimentation.) The 8169S/8110S chips
  apparently are limited to 7.5K frames on transmit. This may require
  some more work, though the framework to handle jumbo frames on RX
  is in place: the re_rxeof() routine will gather up frames than span
  multiple 2K clusters into a single mbuf list.

- Fixed bug in re_txeof(): if we reap some of the TX buffers,
  but there are still some pending, re-arm the timer before exiting
  re_txeof() so that another timeout interrupt will be generated, just
  in case re_start() doesn't do it for us.

- Handle the 'link state changed' interrupt

- Fix a detach bug. If re(4) is loaded as a module, and you do
  tcpdump -i re0, then you do 'kldunload if_re,' the system will
  panic after a few seconds. This happens because ether_ifdetach()
  ends up calling the BPF detach code, which notices the interface
  is in promiscuous mode and tries to switch promisc mode off while
  detaching the BPF listner. This ultimately results in a call
  to re_ioctl() (due to SIOCSIFFLAGS), which in turn calls re_init()
  to handle the IFF_PROMISC flag change. Unfortunately, calling re_init()
  here turns the chip back on and restarts the 1-second timeout loop
  that drives re_tick(). By the time the timeout fires, if_re.ko
  has been unloaded, which results in a call to invalid code and
  blows up the system.

  To fix this, I cleared the IFF_UP flag before calling ether_ifdetach(),
  which stops the ioctl routine from trying to reset the chip.

- Modified comments in re_rxeof() relating to the difference in
  RX descriptor status bit layout between the 8139C+ and the gigE
  chips. The layout is different because the frame length field
  was expanded from 12 bits to 13, and they got rid of one of the
  status bits to make room.

- Add diagnostic code (re_diag()) to test for the case where a user
  has installed a broken 32-bit 8169 PCI NIC in a 64-bit slot. Some
  NICs have the REQ64# and ACK64# lines connected even though the
  board is 32-bit only (in this case, they should be pulled high).
  This fools the chip into doing 64-bit DMA transfers even though
  there is no 64-bit data path. To detect this, re_diag() puts the
  chip into digital loopback mode and sets the receiver to promiscuous
  mode, then initiates a single 64-byte packet transmission. The
  frame is echoed back to the host, and if the frame contents are
  intact, we know DMA is working correctly, otherwise we complain
  loudly on the console and abort the device attach. (At the moment,
  I don't know of any way to work around the problem other than
  physically modifying the board, so until/unless I can think of a
  software workaround, this will have do to.)

- Created re(4) man page

- Modified rlphy.c to allow re(4) to attach as well as rl(4).

Note that this code works for the sample 8169/Marvell 88E1000 NIC
that I have, but probably won't work for the 8169S/8110S chips.
RealTek has sent me some sample NICs, but they haven't arrived yet.
I will probably need to add an rlgphy driver to handle the on-board
PHY in the 8169S/8110S (it needs special DSP initialization).

2bec1c8919 Hook-up the uart(4) driver to the build. For a detailed description
of what uart(4) is and/or is not see the initial commit log of one
of the files in sys/dev/uart (or see share/man/man4/uart.4).

Note that currently pc98 shares the MD file with i386. This needs
to change when pc98 support is fleshed-out to properly support the
various UARTs. A good example is sparc64 in this respect.

We build uart(4) as a module on all platforms. This may break
the ppc port. That depends on whether they do actually build
modules.

To use uart(4) on alpha, one must use the NO_SIO option.

dc7d0dea12 Enhance puc(4) to support uart(4). This includes:
o  Introduce PUC_PORT_TYPE_UART so that we can attach to uart(4),
o  Introduce port sub-types (eg PUC_PORT_UART_NS8250, PUC_PORT_UART_Z8530)
   to handle different hardware and determine resource sizes.
o  Introduce two new IVARs: PUC_IVAR_SUBTYPE and PUC_IVAR_REGSHFT. Both
   are used by uart(4) to get sufficient information to talk to the HW.
o  Introduce PUC_FLAGS_ALTRES to tell puc(4) to try memory mapped I/O
   if I/O port space cannot be allocated, or vice versa.
o  Have ports of type PUC_PORT_TYPE_COM attach to uart(1) if attaching
   to sio(4) fails (due to not having the sio driver).
o  Put struct puc_device_description in struct puc_softc instead of
   having a pointer to a device description in the softc. This allows
   us to create device descriptions on the fly without having to use
   malloc() or otherwise have them staticly defined.
o  Move puc_find_description() from puc.c to puc_pci.c as it's specific
   to PCI.
o  Add EBUS and SBUS frontends for use on sparc64. Note that the P in
   puc stands for PCI, so we kinda mess things up here. It's too soon
   to worry about it though. We'll know what to do about it in time.

NOTE: This commit changes the behaviour of puc(4) to not quieten the
device probe and attach for child devices. The uart(4) driver provides
additional device description that is valuable to have.

dfbd7790d4 Load the kernel at a 64M instead of 5M. The advantage of this is that
we can switch to 64M-sized identity mappings and not having to map the
first 64M. This is especially important because the first 1M contains
the VGA frame buffer and is otherwise a legacy memory range. Best to
make as little assumptions about it as possible. Switching to 64M-sized
mappings is important to avoid creating overlapping translations, which
have the side-effect of triggering machine checks. This is currently
what's preventing us to boot on an Intel Tiger 4.

Note that since we currently use 256M-sized identity mappings, we
would reduce the size of the mappings and consequently increase the
TLB pressure. The performance implications of this are minimal if
measurable at all because identify mappings are not our primary
means for memory management.

Also note that there's no guarantee that physical memory exists at
64M. Then again, we didn't had the guarantee when we were loading at
5M. We'll deal with this when it's a problem.

5fdbb0d222 This is a major rework of the ATA driver (ATAng)
Restructure the way ATA/ATAPI commands are processed, use a common
ata_request structure for both. This centralises the way requests
are handled so locking is much easier to handle.

The driver is now layered much more cleanly to seperate the lowlevel
HW access so it can be tailored to specific controllers without touching
the upper layers. This is needed to support some of the newer
semi-intelligent ATA controllers showing up.

The top level drivers (disk, ATAPI devices) are more or less still
the same with just corrections to use the new interface.

Pull ATA out from under Gaint now that locking can be done in a sane way.

Add support for a the National Geode SC1100. Thanks to Soekris engineering
for sponsoring a Soekris 4801 to make this support.

Fixed alot of small bugs in the chipset code for various chips now
we are around in that corner anyways.

30e27d9623 Add a overhaul of the soundchip initialization for the MSP34xx chipsets
found only many tv-cards.

We currently use more ore less evil hacks (slow_msp_audio sysctl) to
configure the various variants of these chips in order to have
stereo autodetection work.  Nevertheless, this doesn't always work
even though it _should_, according to the specs.
This is, for example, the case for some popular Hauppauge models sold
sold in Germany.

However, the Linux driver always worked for me and others.  Looking at
the sourcecode you will find that the linux-driver uses a very much
enhanced approach to program the various msp34xx chipset variants,
which is also found in the specs for these chips.

This is a port of the Linux MSP34xx code, written by Gerd Knorr
<kraxel@bytesex.org>, who agreed to re-release his code under a
BSD license for this port.

A new config option "BKTR_NEW_MSP34XX_DRIVER" is added, which is required
to enable the new driver.  Otherwise the old code is used.

The msp34xx.c file is diff-reduced to the linux-driver to make later
modifications easier, thus it doesn't follow style(9) in most cases.

7e9024cdd9 Add a facility for devices, specifically network interfaces, that require

with these situations is that they eat up the available DMA address space
very quickly when using mbufs or even mbuf clusters. Additionally this
facility provides a direct mapping between 32-bit integers and these buffers.
This is needed for devices originally designed for 32-bit systems. Ususally
the virtual address of the buffer is used as a handle to find the buffer as
soon as it is returned by the card. This does not work for 64-bit machines
and hence this mapping is needed.

1d80cb1b37 Add the new sparc64 OFW PCI framework, conditional on options OFW_NEWPCI
for now. It introduces a OFW PCI bus driver and a generic OFW PCI-PCI
bridge driver. By utilizing these, the PCI handling is much more elegant
now.

The advantages of the new approach are:
- Device enumeration should hopefully be more like on Solaris now,
  so unit numbers should match what's printed on the box more
  closely.
- Real interrupt routing is implemented now, so cardbus bridges
  etc. have at least a chance to work.
- The quirk tables are gone and have been replaced by (hopefully
  sufficient) heuristics.
- Much cleaner code.

There was also a report that previously bogus interrupt assignments
are fixed now, which can be attributed to the new heuristics.

A pitfall, and the reason why this is not the default yet, is that
it changes device enumeration, as mentioned above, which can make
it necessary to change the system configuration if more than one
unit of a device type is present (on a system with two hme cars,
for example, it is possible that hme0 becomes hme1 and vice versa
after enabling the option). Systems with multiple disk controllers
may need to be booted into single user (and require manual specification
of the root file system on boot) to adjust the fstab.
Nevertheless, I would like to encourage users to use this option,
so that it can be made the default soon.

In detail, the changes are:
- Introduce an OFW PCI bus driver; it inherits most methods from the
  generic PCI bus driver, but uses the firmware for enumeration,
  performs additional initialization for devices and firmware-specific
  interrupt routing. It also implements an OFW-specific method to allow
  child devices to get their firmware nodes.
- Introduce an OFW PCI-PCI bridge driver; again, it inherits most
  of the generic PCI-PCI bridge driver; it has it's own method for
  interrupt routing, as well as some sparc64-specific methods (one to
  get the node again, and one to adjust the bridge bus range, since
  we need to reenumerate all PCI buses).
- Convert the apb driver to the new way of handling things.
- Provide a common framework for OFW bridge drivers, used be the two
  drivers above.
- Provide a small common framework for interrupt routing (for all
  bridge types).
- Convert the psycho driver to the new framework; this gets rid of a
  bunch of old kludges in pci_read_config(), and the whole
  preinitialization  (ofw_pci_init()).
- Convert the ISA MD part and the EBus driver to the new way
  interrupts and nodes are handled.
- Introduce types for firmware interrupt properties.
- Rename the old sparcbus_if to ofw_pci_if by repo copy (it is only
  required for PCI), and move it to a more correct location (new
  support methodsx were also added, and an old one was deprecated).
- Fix a bunch of minor bugs, perform some cleanups.

In some cases, I introduced some minor code duplication to keep the
new code clean, in hopes that the old code will be unifdef'ed soon.

4784a46912 Replace the code for reading and writing the kernel message buffer
with a new implementation that has a mostly reentrant "addchar"
routine, supports multiple message buffers in the kernel, and hides
the implementation details from callers.

The new code uses a kind of sequence number to represend the current
read and write positions in the buffer. This approach (suggested
mainly by bde) permits the read and write pointers to be maintained
separately, which reduces the number of atomic operations that are
required. The "mostly reentrant" above refers to the way that while
it is now always safe to have any number of concurrent writers,
readers could see the message buffer after a writer has advanced
the pointers but before it has witten the new character.

22db1e9ff5 Add "GEOM_FOX", a class which detects and selects between multiple

This class reacts to a label in the first sector of the device,
which is created the following way:

        #    "0123456789abcdef012345..."
        #    "<----magic-----><-id-...>
        echo "GEOM::FOX       someid" | dd of=/dev/da0 conv=sync

NB: Since the fact that multiple disk devices are in fact the same
    device is not known to GEOM, the geom taste/spoil process cannot
    fully catch all corner cases and this module can therefore be
    confused if you do the right wrong things.

NB: The disk level drivers need to do the right thing for this to
    be useful, and that is not by definition currently the case.

3c9a3c9ca3 Major pmap rework to take advantage of the larger address space on amd64
systems.  Of note:
- Implement a direct mapped region using 2MB pages.  This eliminates the
  need for temporary mappings when getting ptes.  This supports up to
  512GB of physical memory for now.  This should be enough for a while.
- Implement a 4-tier page table system.  Most of the infrastructure is
  there for 128TB of userland virtual address space, but only 512GB is
  presently enabled due to a mystery bug somewhere.  The design of this
  was heavily inspired by the alpha pmap.c.
- The kernel is moved into the negative address space(!).
- The kernel has 2GB of KVM available.
- Provide a uma memory allocator to use the direct map region to take
  advantage of the 2MB TLBs.
- Fixed some assumptions in the bus_space macros about the ability
  to fit virtual addresses in an 'int'.

Notable missing things:
- pmap_growkernel() should be able to grow to 512GB of KVM by expanding
  downwards below kernbase.  The kernel must be at the top 2GB of the
  negative address space because of gcc code generation strategies.
- need to fix the >512GB user vm code.

f2c49dd248 Revamp of the syscall path, exception and context handling. The
prime objectives are:
o  Implement a syscall path based on the epc inststruction (see
   sys/ia64/ia64/syscall.s).
o  Revisit the places were we need to save and restore registers
   and define those contexts in terms of the register sets (see
   sys/ia64/include/_regset.h).

Secundairy objectives:
o  Remove the requirement to use contigmalloc for kernel stacks.
o  Better handling of the high FP registers for SMP systems.
o  Switch to the new cpu_switch() and cpu_throw() semantics.
o  Add a good unwinder to reconstruct contexts for the rare
   cases we need to (see sys/contrib/ia64/libuwx)

Many files are affected by this change. Functionally it boils
down to:
o  The EPC syscall doesn't preserve registers it does not need
   to preserve and places the arguments differently on the stack.
   This affects libc and truss.
o  The address of the kernel page directory (kptdir) had to
   be unstaticized for use by the nested TLB fault handler.
   The name has been changed to ia64_kptdir to avoid conflicts.
   The renaming affects libkvm.
o  The trapframe only contains the special registers and the
   scratch registers. For syscalls using the EPC syscall path
   no scratch registers are saved. This affects all places where
   the trapframe is accessed. Most notably the unaligned access
   handler, the signal delivery code and the debugger.
o  Context switching only partly saves the special registers
   and the preserved registers. This affects cpu_switch() and
   triggered the move to the new semantics, which additionally
   affects cpu_throw().
o  The high FP registers are either in the PCB or on some
   CPU. context switching for them is done lazily. This affects
   trap().
o  The mcontext has room for all registers, but not all of them
   have to be defined in all cases. This mostly affects signal
   delivery code now. The *context syscalls are as of yet still
   unimplemented.

Many details went into the removal of the requirement to use
contigmalloc for kernel stacks. The details are mostly CPU
specific and limited to exception_save() and exception_restore().
The few places where we create, destroy or switch stacks were
mostly simplified by not having to construct physical addresses
and additionally saving the virtual addresses for later use.

Besides more efficient context saving and restoring, which of
course yields a noticable speedup, this also fixes the dreaded
SMP bootup problem as a side-effect. The details of which are
still not fully understood.

This change includes all the necessary backward compatibility
code to have it handle older userland binaries that use the
break instruction for syscalls. Support for break-based syscalls
has been pessimized in favor of a clean implementation. Due to
the overall better performance of the kernel, this will still
be notived as an improvement if it's noticed at all.

d85631c4ac Add BASIC i386 binary support for the amd64 kernel. This is largely
stolen from the ia64/ia32 code (indeed there was a repocopy), but I've
redone the MD parts and added and fixed a few essential syscalls.  It
is sufficient to run i386 binaries like /bin/ls, /usr/bin/id (dynamic)
and p4.  The ia64 code has not implemented signal delivery, so I had
to do that.

Before you say it, yes, this does need to go in a common place.  But
we're in a freeze at the moment and I didn't want to risk breaking ia64.
I will sort this out after the freeze so that the common code is in a
common place.

On the AMD64 side, this required adding segment selector context switch
support and some other support infrastructure.  The %fs/%gs etc code
is hairy because loading %gs will clobber the kernel's current MSR_GSBASE
setting.  The segment selectors are not used by the kernel, so they're only
changed at context switch time or when changing modes.  This still needs
to be optimized.

42da33c444 Update the DRM to the latest from DRI CVS. Includes some bugfixes and removal
of the infrastructure for the gamma driver which was removed a while back.
The DRM_LINUX option is removed because the handler is now provided by the
linux compat code itself.

87b4a25958 Add device driver support for the ASIX Electronics AX88172 USB 2.0
ethernet controller. The driver has been tested with the LinkSys
USB200M adapter. I know for a fact that there are other devices out
there with this chip but don't have all the USB vendor/device IDs.

Note: I'm not sure if this will force the driver to end up in the
install kernel image or not. Special magic needs to be done to exclude
it to keep the boot floppies from bloating again, someone please
advise.

daabb372ca Separate the encoding/decoding functions for struct disklabel into a
separate source file which can be used from both kernel and userland code.

18b492fc8c Bump the config version to force people to upgrade their config(8)
so the fix for emitting multiple instances of .o files will prevent
link errors on LINT.

e965edfda2 Add MAC_ALWAYS_LABEL_MBUF to options; this permits the administrator
to force the allocation of MAC labels for all mbufs regardless of
whether a configured policy requires labeling when the mbuf is
allocated.  This can be useful it you anticipate loading a fully
labeled policy after boot and don't want mbufs to exist without
label storage, for performance measurement purposes, etc.  It also
slightly lowers the overhead of m_tag labeling due to removing the
decision logic.

While here, improve commenting of other MAC options.
