f8ad22919e 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.

ab2f9fc41a Systems based on the ICH2/ICH2-M chip from Intel have a defect where
the chip can cause a PCI protocol violation in under certain scenarios.
The workaround is to rewrite the EEPROM to disable Dynamic Standby Mode.

Once the EEPROM is rewritten, the system needs to be rebooted in order
to pick up the new settings.

This has been tested on several ICH2/ICH2-M systems, found in 815E based
boards, and usually identified by the presence of the 82562 ET/EM PHY.

Thanks to: Mike Tansca, Paul Saab for samples of the problematic boards.

f364d4ac36 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.

37decc93f5 Implement MTX_RECURSE flag for mtx_init().
All calls to mtx_init() for mutexes that recurse must now include
the MTX_RECURSE bit in the flag argument variable. This change is in
preparation for an upcoming (further) mutex API cleanup.
The witness code will call panic() if a lock is found to recurse but
the MTX_RECURSE bit was not set during the lock's initialization.

The old MTX_RECURSE "state" bit (in mtx_lock) has been renamed to
MTX_RECURSED, which is more appropriate given its meaning.

The following locks have been made "recursive," thus far:
eventhandler, Giant, callout, sched_lock, possibly some others declared
in the architecture-specific code, all of the network card driver locks
in pci/, as well as some other locks in dev/ stuff that I've found to
be recursive.

b63adaba93 Fix a bug brought to light by the people working on SMPng. I don't quite
understand exactly what it is about SMPng that tickles this bug. What I
do know is that the foo_init() routine in most drivers is often called
twice when an interface is brought up. One time is due to the ifconfig(8)
command calling the SIOCSIFFLAGS ioctl to set the IFF_UP flag, and another
is probably due to the kernel calling ifp->if_init at some point. In any
case, the SMPng changes seem to affect the timing of these two events in
such a way that there is a significant delay before any packets are sent
onto the wire after the interface is first brought up. This manifested
itself locally as an SMPng test machine which failed to obtain an address
via DHCP when booting up.

It looks like the second call to fxp_init() is happening faster now than
it did before, and I think it catches the chip while it's in the process
of dealing with the configuration command from the first call. Whatever
the case, a FXP_CSR_SCB_CNA interrupt event is now generated shortly after
the second fxp_init() call. (This interrupt is apparently never generated
by a non-SMPng kernel, so nobody noticed.)

There are two problems with this: first, fxp_intr() does not handle the
FXP_CSR_SCB_CNA interrupt event (it never tests for it or does anything
to deal with it), and second, the meaning of FXP_CSR_SCB_CNA is not
documented in the driver. (Apparently it means "command unit not active.")
Bad coder. No biscuit.

The fix is to have the FXP_CSR_SCB_CNA interrupt handled just like the
FXP_SCB_STATACK_CXTNO interrupt. This prevents the state machine for
the configuration/RX filter programming stuff from getting wedged for
several seconds and preventing packet transmission.

b0e74737e9 Fix an alpha-only race which causes the transmit side of the chip to
lock up under moderate to heavy load.

The status & command fields share a 32-bit longword.  The programming
API of the eepro apparently requires that you update the command field
of a transmit slot that you've already given to the card.  This means
the card could be updating the status field of the same longword at
the same time. Since alphas can only operate on 32-bit chunks of
memory, both the status & command fields are loaded from memory &
operated on in registers when the following line of C is executed:

                sc->cbl_last->cb_command &= ~FXP_CB_COMMAND_S;

The race is caused by the card DMA'ing up the status at just the wrong
time -- after it has been loaded into a register & before it has been
written back.  The old value of the status is written back, clobbering
the status the card just DMA'ed up. The fact that the card has sent
this frame is missed & the transmit engine appears to hang.

Luckily, as numerous people on the freebsd-alpha list pointed out, the
load-locked/store-conditional instructions used by the atomic
functions work with respect changes in memory due to I/O devices.  We
now use them to safely update the command field.

2be6fce1fa Make the fxp driver work on alpha, rather than panic the machine on boot
and/or when using the card.

o Convert the driver to using bus_space.  This allows alphas with
fxp's to boot, rather than panic'ing because rman_get_virtual()
doesn't really return a virtual address on alphas.

o Fix an alpha unaligned access error caused by some misfeature of
gcc/egcs: if link_addr & rbd_addr in the fxp_rfa struct are 32 bit
quantities, egcs will assume they are naturally aligned. So it will do
a ldl & some shifty/masky to twiddle 16 bit values in fxp_lwcopy().
However, if they are 16-bit aligned, the ldl will actually be done on
a 16-bit aligned value & we will panic with an unaligned access
error... Changing their definition to an array of chars seems to fix
this.  I obtained this from NetBSD.

code smarter. The idea here is to change the module's internal name
from "foo" to "if_foo" so that ifconfig can tell a network driver from
a non-network one. However doing this doesn't work correctly no matter
how you slice it. For everything to work, you have to change the name
in both the driver_t struct and the DRIVER_MODULE() declaration. The
problems are:

- If you change the name in both places, then the kernel thinks that
  the device's name is now "if_foo", so you get things like:

if_foo0: <FOO ethernet> irq foo at device foo on pcifoo
if_foo0: Ethernet address: foo:foo:foo:foo:foo:foo

  This is bogus. Now the device name doesn't agree with the logical
  interface name. There's no reason for this, and it violates the
  principle of least astonishment.

- If you leave the name in the driver_t struct as "foo" and only
  change the names in the DRIVER_MODULE() declaration to "if_foo" then
  attaching drivers to child devices doesn't work because the names don't
  agree. This breaks miibus: drivers that need to have miibuses and PHY
  drivers attached never get them.

In other words: damned if you do, damned if you don't.

This needs to be thought through some more. Since the drivers that
use miibus are broken, I have to change these all back in order to
make them work again. Yes this will stop ifconfig from being able
to demand load driver modules. On the whole, I'd rather have that
than having the drivers not work at all.

that was made with a date code of 0699 (June 99).  The submitter shows

087d4857e5 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

179a5ad365 Work around a bug in the 82557 NIC where the receiver will lock up
if it is in 10Mbps mode and gets certain types of garbage prior to
the packet header. The work-around involves reprogramming the
multicast filter if nothing is received in some number of seconds
(currently set at 15). As a side effect, implemented complete support
for multicasting rather than the previous 'receive all multicasts'
hack, since we now have the ability to program the filter table.
Fixed a serious bug which crept in with the timeout() changes;
the cookie was only saved on the first timeout() call in fxp_init()
and wasn't updated in the most common place in fxp_stats_update()
when the timeout was rescheduled. This bug would have resulted in
an eventual panic if fxp_stop() was called (which happens when any
interface flags are changed, for example).
Fixed a bug in Alpha support that would have caused the TxCB
descriptor chain to span a page boundry, causing serious problems
if the pages didn't happen to be contiguous.
Removed some gratuitous bit masking that was left over from an
older implementation.
Fixed a bug where too much was copied from the configuration
template, spilling over into memory that followed it.
