948c244d94 Add preliminary support for the Hawking PN672TX CardBus cards.
# Preliminary because there are some subtle things the NetBSD driver does
# that we don't do yet.  My card works for me w/o them.

3097aa70be Dynamically configure the width of the srom. This code comes from
OpenBSD who got the code (or the idea) from the NetBSD tlp driver.

This gets some cardbus dc cards working (either completely or nearly
so).  It also appears to get additional pci cards working, without
breaking working ones.

# Maybe some additional work is needed here.  Also, the cardbus attachment
# might need to match on the CIS rather than on the vendor/device so we have
# a finer level of detail as to what the card is.  Technically, the
# vendor/device fields are undefined for CardBus (even though most cards are
# using common silicon with pci models).

e4fc250c15 Device Polling code for -current.
Non-SMP, i386-only, no polling in the idle loop at the moment.

To use this code you must compile a kernel with

        options DEVICE_POLLING

and at runtime enable polling with

        sysctl kern.polling.enable=1

The percentage of CPU reserved to userland can be set with

        sysctl kern.polling.user_frac=NN (default is 50)

while the remainder is used by polling device drivers and netisr's.
These are the only two variables that you should need to touch. There
are a few more parameters in kern.polling but the default values
are adequate for all purposes. See the code in kern_poll.c for
more details on them.

Polling in the idle loop will be implemented shortly by introducing
a kernel thread which does the job. Until then, the amount of CPU
dedicated to polling will never exceed (100-user_frac).
The equivalent (actually, better) code for -stable is at

	http://info.iet.unipi.it/~luigi/polling/

and also supports polling in the idle loop.

NOTE to Alpha developers:
There is really nothing in this code that is i386-specific.
If you move the 2 lines supporting the new option from
sys/conf/{files,options}.i386 to sys/conf/{files,options} I am
pretty sure that this should work on the Alpha as well, just that
I do not have a suitable test box to try it. If someone feels like
trying it, I would appreciate it.

NOTE to other developers:
sure some things could be done better, and as always I am open to
constructive criticism, which a few of you have already given and
I greatly appreciated.
However, before proposing radical architectural changes, please
take some time to possibly try out this code, or at the very least
read the comments in kern_poll.c, especially re. the reason why I
am using a soft netisr and cannot (I believe) replace it with a
simple timeout.

2dfc960a5b Avoid an unnecessary copy of a packet if it is already in a single mbuf.
Introduce an additional device flag for those NICs which require the
transmit buffers to be aligned to 32-bit boundaries.

(the equivalen fix for STABLE is slightly simpler because there are
no supported chips which require this alignment there.)

9ed346bab0 Change and clean the mutex lock interface.
mtx_enter(lock, type) becomes:

mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks)
mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized)

similarily, for releasing a lock, we now have:

mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN.
We change the caller interface for the two different types of locks
because the semantics are entirely different for each case, and this
makes it explicitly clear and, at the same time, it rids us of the
extra `type' argument.

The enter->lock and exit->unlock change has been made with the idea
that we're "locking data" and not "entering locked code" in mind.

Further, remove all additional "flags" previously passed to the
lock acquire/release routines with the exception of two:

MTX_QUIET and MTX_NOSWITCH

The functionality of these flags is preserved and they can be passed
to the lock/unlock routines by calling the corresponding wrappers:

mtx_{lock, unlock}_flags(lock, flag(s)) and
mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN
locks, respectively.

Re-inline some lock acq/rel code; in the sleep lock case, we only
inline the _obtain_lock()s in order to ensure that the inlined code
fits into a cache line. In the spin lock case, we inline recursion and
actually only perform a function call if we need to spin. This change
has been made with the idea that we generally tend to avoid spin locks
and that also the spin locks that we do have and are heavily used
(i.e. sched_lock) do recurse, and therefore in an effort to reduce
function call overhead for some architectures (such as alpha), we
inline recursion for this case.

Create a new malloc type for the witness code and retire from using
the M_DEV type. The new type is called M_WITNESS and is only declared
if WITNESS is enabled.

Begin cleaning up some machdep/mutex.h code - specifically updated the
"optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN
and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently
need those.

Finally, caught up to the interface changes in all sys code.

feb78939ee NEWCARD/Cardbus -
This commit adds support for Xircom X3201 based cardbus cards.
Support for the TDK 78Q2120 MII is also added.
IBM Etherjet, Intel and Xircom cards uses these chips.

Note that as a result of this commit, some Intel/DEC 21143 based cardbus
cards will also attach, but not get link.  That is being looked at.

d1ce910572 First round of converting network drivers from spls to mutexes. This
takes care of all the 10/100 and gigE PCI drivers that I've done.
Next will be the wireless drivers, then the USB ones. I may pick up
some stragglers along the way. I'm sort of playing this by ear: if
anyone spots any places where I've screwed up horribly, please let me
know.

5c1cfac46e Add support for parsing the media blocks from the SROM on 21143
adapters. This is necessary in order to make this driver work with
the built-in ethernet on the alpha Miata machines. These systems
have a 21143-PC chip on-board and optional daughtercards with either
a 10/100 MII transceiver or a 10baseT/10base2 transceiver. In both
cases, you need to twiddle the GPIO bits on the controller in order
to turn the transceivers on, and you have to read the media info
from the SROM in order to find out what bits to twiddle.

78999dd117 Special-case the LED twiddling code so that it doesn't do anything
on the NEC VersaPro NoteBook PC. This 21143 implementation has no LEDs,
and flipping the LED control bits somehow stops it from establishing
a link. We check the subsystem ID and don't flip the LED control
bits for the NEC NIC.

79d11e0960 Apply patch to the dc driver to handle Macronix MX98715AEC-C/D/E chips,
which differ slightly from the Macronix MX98715AEC chip on the sample
adapter that I have in that the multicast hash table is only 128 bits
wide instead of 512. New adapters are popping up with this chip, and
due to improper handling of the smaller hash table, broadcast packets
were not being received correctly.

318b02fdb9 Rework the support for the internal autonegotiation on the 21143 and
workalike chips (Macronix 98713A/98715 and PNIC II). Timing is somewhat
critical: you need to bring the link as soon as possible after NWAY
is done, and the old one second polling interval was too long. Now
we poll every 10th of a second until NWAY completes (at which point
we return to the 1 second interval again to keep an eye on the link
state).

I tested all the other cards I had on hand to make sure I didn't bust
any of them and they seem to work (including the MII-based 21143 card).
This should fix some autoneg problems with DE500-BA cards and the
built-in 10/100 ethernet on some alpha systems.

(Now before anyone asks why I never noticed this before, the old code
worked just find with the Intel swich I used for testing back in NY.
Apparently not all switches are as picky about the timing.)

88d739dc5f Add support for the Davicom DM9102A 10/100 ethernet controller chip.
This is just to make sure we initialize the chip correctly: we need to
make the sure the port select bit in CSR6 is set properly so that we
use the internal PHY for 10/100 support. (The eval boards I have also
include an external HomePNA PHY, but I need to play with that more
before I can support it.)

91cc2adb2e Fix some problems reported by Mike Pritchard:
- Add a flag DC_TX_INTR_ALWAYS which causes the transmit code to
  request a TX done interrupt for every packet. The PNIC seems to need
  this to insure that the sent TX buffers get reaped in a timely fashion.

- Try to unreset the SIA as soon as possible after resetting the whole
  chip.

- Change dcphy to support either 10/100 or 10Mbps only NICs. The
  built-in 21143 ethernet in Compaq Presario machines is 10Mbps only
  and it doesn't work right if we try to advertise 100Mbps modes during
  autoneg. When restricted to only 10mbps modes, it works fine.

  Note that for now, I detect this condition by checking the PCI
  subsystem ID on this NIC (which has a Compaq vendor/device ID).
  Yes, I know that's what the SROM is supposed to be for. I'm deliberately
  ignoring the SROM wherever possible. Sue me.

The latter two fixes allow if_dc to work correctly with the built-in
ethernet on certain Compaq Presario boxes. There are liable to be quite
a few people using these as their home systems who might want to try
FreeBSD; may as well be nice to them.

Now if anybody out there has an Alpha miata with 10Mbps ethernet and
can show me the output from pciconf -l on their system, I'd be grateful.
