does a "restore data pointers" when reselected after disconnecting in
the middle of a DMA transfer). The driver needs a different way to know
which script to continue the DMA transfer. The message-in for the "restore
data pointers" loses the original "resume" script, and the driver would
attempt to continue the DMA transfer at the beginning of the current DMA
chunk, rather than at the point the disconnect occured. The result was a
spurious console message, and a trashed filesystem.
clobbers my SMC. Now I can really use a generic kernel with my SMC @0x300.
This change has been tested on various machines with ne2000 and 3c509 baords.

to be reloaded every time it is checked. This avoids a condition where
it can be cached in a register in such a way that updates to the flags in
an interrupt handler to not be noticed, which in turn causes the process
doing the i/o to sleep forever. Bug report and suggested fix from
Hiroshi HORIMOTO <horimoto@cs-yuugao.cs.sist.ac.jp>, PR $4460.

if another instance of the driver is interface is using it).
i/o-mapped space to always be used), we discover that at least one

to look specifically at the address it was provided *only*, since the
scan isn't safe (it can stomp on cards that will be probed later, like
NE2000 clones).
- Do PCI space configuration like the other drivers. In particular,
don't _disable_ the space we're not using because some lame firmware
implementations might not reenable it on warm boot. Also, prefer
memory space always.
- Make match and info-gathering in attach table-driven.
- Rearrange things a bit to be a bit more visually pleasing during boot.
Also, fixup some #include problems.
- clean up debug code
- Don't check ATAPI signature when probing ATA drives, ATAPI devices were
detected before
- Reset controller after disks probes. The probe, with some combinations of
ATA/ATAPI device keep it in a mostly working, but strange state (with busy
led on)
- The WDCF_IRQ_WAIT flag is now cleared by wdc_ata_intr and wdc_atapi_intr
when appropriate (helps recover from failure conditions)
- In wdcunwedge, send ATAPI_SOFT_RESET to non-ata drives
(helps recover from failure conditions)
- in wdctimeout be a bit more verbose when we missed an interrupt
- Always Increment xfer->c_skip where it should be
- Set the ITSDONE flag when a polled command completed.
for 12-bit addresses. This causes PCMCIA cards mapped at 0x400 and higher
to not function properly. However, the range 0x300-0x3ff causes some
laptops (e.g. the NEC Versa 6030X) to hang if cards are mapped there.
So, after some experimentation, we compromise. If the probe discovers
a 12-bit address bus, don't trust it. Instead, use the range 0x330-0x3ff.
This has been shown to work on the laptops that the 0x300-0x3ff range is
known to fail on.

more robust in resource shortage situations, basically identical to
code I added to the "ahc" driver some time ago.
Thanks to Brad Spencer for the testing help.
* Make the ring buffer size and water marks patchable, and allocate the buffer
separately.
* Do the ttymalloc() at attach time.
* Reorganize the receive buffer so the status and data pair are next to each
other. This is slightly faster.
* Make sure we actually do turn off interrupts in comclose() if we have DDB
configured and it's not the console. (D'oh!!!!)
* When we exhaust the current transmit run, turn off transmit interrupts in
comintr(), so we're fairly sure we don't get another one.
* Nuke the silly lsrmap[] idea; it's slower in the normal case.
* Cache the l_rint pointer in the soft interrupt routine.
* Carrier detect (TS_CARR_ON) is based on the actual DCD bit, even if it's
being ignored.
* Set TS_WOPEN early on in zsopen().
* Don't disable interrupts on the console during close if we have DDB.
Inert changes:
* Don't handle ZS_HWFLAG_NO_DCD here; the frontend does it.
* Deprecate `register'.
* Use SET(), CLR(), and ISSET().
More performance changes:
* Rototill receive handling; use a backpressure mechanism to prevent livelock.
* Output silo/ibuf overflow warnings at most once per minute, from a callout.
* When we exhaust the current transmit run, turn off transmit interrupts in
zstty_txint(), so we're fairly sure we don't get another one.

Supports changing media with ifconfig's "media" directive.
This splits the 3c503 functionality out of the ISA "ed" driver, much the
same way NE2000 support was split out.
control any more, and the speed of changing DTR isn't really an issue. Also,
the old code created a bug where zsparam() might have failed to set some
registers.
Change the interface to zs_hwiflow(); just have it use zst_rx_blocked.
Make zs_modem() a tiny bit faster.
Do RTS updates immediately; do not allow them to be held.
Stop output as fast as possible when DCD is deasserted.
Do *not* automatically drop DTR when DCD is deasserted.
Only check for rr0 bits that we care about (DTR and DCD).
Make sure we turn on DTR and/or RTS as appropriate during open.
Rearrange close sequence so the tty is flushed before turning off interrupts.
Deal with `softcar' and the console device by silently asserting CLOCAL and
|HUPCL, as in com driver.
Do *not* fiddle with DTR when changing the line speed.
Make sure we update the tty's carrier status when CLOCAL or MDMBUF is changed.
Only change rr1 when we actually need to turn on or off TIE.

- Rename pcic_intr_alloc_mask to pcic_isa_intr_alloc_mask, since it's
an ISA-specific thing.
- When allocating/establishing the PCIC's interrupt (for card events),
do error checking, and pay attention to the intr_alloc_mask.
for the built-in SCSI on NEC Versa docking stations, and if a card
allocates that IRQ, it will never get interrupts. This caused the
default kernel to not work on these laptops, as IRQ 10 was often the
first free IRQ.

Also, add a big comment describing exactly what we're checking when

The RST check should help weed-out non-matches before they get to the
fairly invasive memory check.
should creation/initialization of a ccb fail. Also, don't panic in

Also, fix the scb freelist fencepost, like the aha/bha/uha drivers.

- add a type field to the isapnp_pin struct and set to IST_EDGE or
IST_LEVEL depending on the card configuration data.
- use the irq type field in all the drivers instead of hardcoding it.
Adjust the number of ccbs allocated during initialization.
Every ccb could potentially lock 64k of memory for dma buffers if bounce
buffers are used. Instead of BHA_CCB_MAX ccbs using 2MByte, only
sc_link.openings ccbs per device are allocated. Thus we now use only
256KByte per device present.
(hannken)
Fix a couple of errors in bha_create_ccbs():
- Don't ever let the number of CCBs be creater than BHA_CCB_MAX.
- Fix a fencepost that caused the last CCB allocated to never be put
on the freelist.

change KEYSYM_HOLE to KEYSYM_NOP most places in those tables.
Map the `R' function keys with KEYSYM_FUNC_R instead of the
arrow key strings so that numlock indirection works.
- at end of attach, explicitely select an existing drive. This fixes hangs
some users reported (such as the one reported in port-i386/4247).
- Some atapi cdrom drives (e.g. Nec 24x) don't enables their registers before
a controller reset is issued. The controller probe routine is changed as
follow: issue a controller reset. If fail, test atapi signature on slave.
If fail, wait 5s and retry a reset. If the second reset fail, return(0).
If the first reset succeed, test presence of a master drive:
atapi signature, and if this fail RO/RW registers test. If no master, test
atapi signature on slave. If no slave, return 0.
"A sequence step of 0 after a select with ATN can be a selection
timeout, or it can also indicate the target did not respond with
a message out phase. The latter will occur on very old SCSI
devices which do not respond to the ATN signal and go directly to
the command phase".
* Make sure all uses of the data pointer are type-cast appropriately.
* Eliminate the super-user check in the KIOCSKEY case (back as it was).
* Return ENOTTY if the ioctl command code is unrecognized.
Instead, print a diagnostic and return. (Some drivers do this already.)
Also, normalize the diagnostic message, and fix some places where the
printfs were getting ugly.
- Work around a bug in the 82557 that causes the receiver to lock up
in certain conditions by kicking the multicast address filter if we
haven't heard anything come down the wire for some period of time.
- Fix a bug that could cause TxCB descriptor chains to cross page boundaries
on the Alpha.
- Remove some unneeded register masking.
- Fix a bug where too much data was copied from the config template, causing
memory corruption.
- Fix handing of if_timer (it was be cleared too early in some cases).
- Attempt to reduce the chances of receiver overrun by doubling the
number of receive DMA segments, and processing receive interrupts
before transmit interrupts.
- Remove a gratuitous assignment.
- Fix a bug where incoming packets were counted twice.

of the 16650, taken from the Linux driver.
This should be extended to use, for example, higher trigger levels for
the bigger 16650 FIFO, and its capability for using a smaller divisor
and thus higher speeds. But this patch is very useful for 16650 users
already.

The isa attachment code is in isa/lpt_isa.c now, which attaches to the
already created ic/lpt* files.
You don't need to change your config files, but you need to re-"config" if
using lpt at isa.
XXX The "lpt" device definition should be in sys/conf/files instead, but to
my knowledge, there are some ports which have private copies of lpt, and would
choke on that. No need to make people unhappy 7 days before release branching.
The following patch employs a smarter adaptive polling
scheme. It also improves the comments, in particular giving
due credit to Phil Budne for his efforts in nunderstanding
the device. It also relaxes the pattern for auto config so
more devices match.

but do not assume any entopy is gathered. It can be enabled using an
IOCTL again if the user desires.
Note that the mix function uses xor, so at worse an attacker can twiddle
bits in the pool, but not into a known state assuming it started as
an unknown.
Over the next few days (thank goodness for long weekends) I'll be hunting
down device drivers and adding hooks to gather entropy from many devices,
and adding the conf.c changes to the various port's device structs to
define major numbers for /dev/random and /dev/urandom.
