This is just a cleanup here (modulo rev.1.108 of kern/tty.c), since the

handle both speeds naturally handled all cases.

It is a pretty hard to come up with even a theoretical concept of
a device driver which would always fail open and close with ENODEV.
Change the defaults to be nullopen() and nullclose() which simply
does nothing.
Remove explicit initializations to these from the drivers which
already used them.
- Removed conversion of a zero input speed to the output speed. This
has been done better in ttioctl() since rev.1.108 of kern/tty.c
almost 5 years ago. comparam() did the conversion incompletely for
the case where the output speed is also zero. It had complications
to avoid using zero speeds, but would still have used a zero input
speed for setting watermarks if kern/tty.c had passed one.
- Never permit the input speed to be different from the output speed.
There was no validity check on the input speed for the case of a zero
output speed. Then we didn't change the physical speeds, but we used
the unvalidated input speed for setting watermarks and didn't return
an error, so ttioctl() stored the unvalidated input speed in the tty
struct where it could cause problems later.
- Removed complications that were to avoid using a divisor of 0. The
divisor is now always valid if the speed is accepted.

all relevant interrupt disablement became soft. The recursion is
harmless unless there are other bugs, but it breaks an invariant so
it is fatal if spinlocks are witnessed.
in the loopback test in the probe. The delay was too short for consoles
at speeds lower than about 3200 bps. This shouldn't have caused many
problems, since such low speeds are rare and the probe is forced to
succeed for consoles.
and the Z8530 drivers used the I/O address as a quick and dirty way to
determine which channel they operated on, but formalizing this by
introducing iobase is not a solution. How for example would a driver
know which channel it controls for a multi-channel UART that only has a
single I/O range?
Instead, add an explicit field, called chan, to struct uart_bas that
holds the channel within a device, or 0 otherwise. The chan field is
initialized both by the system device probing (i.e. a system console)
or it is passed down to uart_bus_probe() by any of the bus front-ends.
As such, it impacts all platforms and bus drivers and makes it a rather
large commit.
Remove the use of iobase in uart_cpu_eqres() for pc98. It is expected
that platforms have the capability to compare tag and handle pairs for
equality; as to determine whether two pairs access the same device or
not. The use of iobase for pc98 makes it impossible to formalize this
and turn it into a real newbus function later. This commit reverts
uart_cpu_eqres() for pc98 to an unimplemented function. It has to be
reimplemented using only the tag and handle fields in struct uart_bas.
Rewrite the SAB82532 and Z8530 drivers to use the chan field in struct
uart_bas. Remove the IS_CHANNEL_A and IS_CHANNEL_B macros. We don't
need to abstract anything anymore.

When performing our register test, be careful
to avoid resetting the chip when pausing the
controller. The test reads the HCNTRL register
and then writes it back with the PAUSE bit
explicitly set. If the last write to the controller
before our probe is to reset it, the CHIPRST
bit will still be set, so we must mask it off
before the PAUSE operation. On some chip versions,
we cannot access registers for a few 100us after
a reset, so this inadvertant reset was causing PCI
errors to occur on the read to check for paused

IF_HANDOFF() does it for us behind the scenes. Remove the extra call
to re_start() otherwise we try to transmit twice.
In re_encap(), fix the code that guards against consuming too many
descriptors in the TX ring so that it actually works. With the
new 8169S chip, I was able to hit a corner case that drained the
free descriptor count all the way to 0. This is not supposed to
be possible.
COM_NOFIFO() and COM_ESP cases are supposed to be a subsets of the
plain 16550A case, but 16650-related changes made the former fall into
the latter and then both fall into general code for printing the tx
fifo size. This mainly caused hard to parse boot messages like:
"sio0: type 16550A fifo disabled lookalike with 1 bytes FIFO".
COM_NOFIFO() on an ESP port gave a larger mess whose extent is not
clear.

defined values instead of hard-coded values. Don't repeat the register
access part of the code 4 times times or triple-space statements. This
fixes half of the style bugs in rev.1.172.
Hardware flow control of 16650As is still officially unsupported. I
was mistaken about it being broken. It is broken in 16650s but is
fixed in 16650As except for the maximum trigger level (which is no
longer used). Testing of the 16650's broken hardware flow control
watermarks by programming them on 16950s showed that their effects are
not too bad if the fifo size and trigger level are reasonably large
(16 is much better than 8).
an UART interface could get stuck when a new interrupt condition
arose while servicing a previous interrupt. Since an interrupt was
already pending, no new interrupt would be triggered.
Avoid infinite recursion by flushing the Rx FIFO and marking an
overrun condition when we could not move the data from the Rx
FIFO to the receive buffer in toto. Failure to flush the Rx FIFO
would leave the Rx ready condition pending.
Note that the SAB 82532 already did this due to the nature of the

precisely where locking would be needed before adding it, but it
seems uart(4) draws slightly too much attention to have it without
locking for too long.
The lock added is a spinlock that protects access to the underlying

hardware interface grabs the lock. Roughly speaking this serializes
the methods. Exceptions are the probe, attach and detach methods.

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).

Real code to follow, once I get past some boot issues on my pc98 boxes
with recent current.
It improves on sio(4) in the following areas:
o Fully newbusified to allow for memory mapped I/O. This is a must
for ia64 and sparc64,
o Machine dependent code to take full advantage of machine and firm-
ware specific ways to define serial consoles and/or debug ports.
o Hardware abstraction layer to allow the driver to be used with
various UARTs, such as the well-known ns8250 family of UARTs, the
Siemens sab82532 or the Zilog Z8530. This is especially important
for pc98 and sparc64 where it's common to have different UARTs,
o The notion of system devices to unkludge low-level consoles and
remote gdb ports and provides the mechanics necessary to support
the keyboard on sparc64 (which is UART based).
o The notion of a kernel interface so that a UART can be tied to
something other than the well-known TTY interface. This is needed
on sparc64 to present the user with a device and ioctl handling
suitable for a keyboard, but also allows us to cleanly hide an
UART when used as a debug port.
Following is a list of features and bugs/flaws specific to the ns8250
family of UARTs as compared to their support in sio(4):
o The uart(4) driver determines the FIFO size and automaticly takes
advantages of larger FIFOs and/or additional features. Note that
since I don't have sufficient access to 16[679]5x UARTs, hardware
flow control has not been enabled. This is almost trivial to do,
provided one can test. The downside of this is that broken UARTs
are more likely to not work correctly with uart(4). The need for
tunables or knobs may be large enough to warrant their creation.
o The uart(4) driver does not share the same bumpy history as sio(4)
and will therefore not provide the necessary hooks, tweaks, quirks
or work-arounds to deal with once common hardware. To that extend,
uart(4) supports a subset of the UARTs that sio(4) supports. The
question before us is whether the subset is sufficient for current
hardware.
o There is no support for multiport UARTs in uart(4). The decision
behind this is that uart(4) deals with one EIA RS232-C interface.
Packaging of multiple interfaces in a single chip or on a single
expansion board is beyond the scope of uart(4) and is now mostly
left for puc(4) to deal with. Lack of hardware made it impossible
to actually implement such a dependency other than is present for
the dual channel SAB82532 and Z8350 SCCs.
The current list of missing features is:
o No configuration capabilities. A set of tunables and sysctls is
being worked out. There are likely not going to be any or much
compile-time knobs. Such configuration does not fit well with
current hardware.
o No support for the PPS API. This is partly dependent on the
ability to configure uart(4) and partly dependent on having
sufficient information to implement it properly.
As usual, the manpage is present but lacks the attention the
software has gotten.
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.
For the floppy driver, use fdcontrol to manipulate density selection.
For the CD drivers, the 'a' and 'c' suffix is without actual effect and
any applications insisting on it can be satisfied with a symlink:

such a card is ejected, we'd panic. Instead, just ignore it.
I should also add a sanity check in the FUNCID code as well, but this
isn't wrong since the check is cheap and happens infrequently.
and replace it with the more intuitive name PCIR_BARS.
- Add a PCIR_BAR(x) macro that returns the config space register offset of
the 32-bit BAR x.

switched from PCCARD_MEM_FOO to PCCARD_A_MEM_FOO, yet we didn't change
exca in all the right places. Do so now. Also use PCCARD_WIDTH_AUTO
rather than the magic cookie 0.
change also disables interrupts around non-S4 suspends whereas before we
did not do this. Our version of AcpiEnterSleepStateS4bios was almost
identical to the ACPICA version.
- Add a new PCIM_HDRTYPE constant for the field in PCIR_HDRTYPE that holds
the header type.
- Replace several magic numbers with appropriate constants for the header
type register and a couple of PCI_FUNCMAX.
- Merge to amd64 the fix to the i386 bridge code to skip devices with
unknown header types.

reading the CIS on some cards. However, not all just yet. This makes
at least some of the xircom cards that weren't working to work. It
doesn't make my home and away card work, however.
o Don't get the card offset wrong. This is the biggest hassle for
reading the CIS. The old code was just so wrong I can't believe that
it worked at all.
o Don't set the bit that allows/forces 16-bit memory access to the
memory. It is hard coded with 0x80.
o Don't need to slow down memory access with wait-states. OLDCARD didn't
need them and it doesn't hurt anything.
o remove bogus grousying in comment.
Bug Fixes:
- Allow users to use LAA
- Remember promiscuous mode settings while bridging
- Allow gratuitous arp's to be sent

METEORSSIGNAL ioctl. Applications use this ioctl with the value
METEOR_SIG_MODE_MASK (0xFFFF0000, -65536) to reset signal delivery,
but revision 1.126 caused the driver to return EINVAL in this case.
Interestingly, the same METEORSSIGNAL ioctl in the meteor driver uses
0 to reset signal delivery.
This commit allows METEOR_SIG_MODE_MASK as a synonym for 0 in the
bktr driver, and restructures the code a bit so that it is otherwise
identical between the bktr and meteor drivers.
compatibility routine, go ahead and accept that as 'success'. A
properly written compatible driver should return < 0 for both the
compat match and compat probe routines, so this will wind up doing the
right thing.
