- The "ess" device does not need a "midibus" interface attribute; it
attaches an "opl" instance which itself attaches the "midi".
- Be explicit about using the "ess" interface attribute when attaching
the "joy" and "opl" instances.

Add support for Nuvoton NCT5104D GPIO chips, as found on PC Engines APU
systems. From Andrew Doran in PR kern/54648.

Merge isaki-audio2 branch, the overhaul of audio subsystem.
- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency
conversions are completely handled in the upper layer. So the hard-
ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
- Obsoletes query_encoding and add query_format instead.
- Obsoletes set_params and add set_format instead.
- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).

Some file paths are changed:
- dev/audio.c -> dev/audio/audio.c (rewritten)
- dev/audiovar.h -> dev/audio/audiovar.h

Add the finsio(4) driver. This driver supports the Hardware Monitor
device in the Fintek LPC Super I/O chips, this includes the following
list:

- F71805F
- F71806F
- F71862FG

This has been adapted from the fins(4) driver available in OpenBSD, which
only supported F71805F.

Tobias Nygren <tnn> and myself added support for the other chips; thanks go
to Tobias for testing the driver with a Fintek F71882 chip.

Certain misguided people have complained, NetBSD only runs rare or

Rename it(4) to itesio(4) to accomodate for the following changes:

- The driver now uses the Super I/O address port as port argument in
the configuration file. The Environmental Controller base address is
fetched by the Super I/O EC LDN configuration registers.

- Invalidate voltage sensors if data returned is 0xff.

- Use the Super I/O Global Configuration Registers Chip ID[12] and Device
Revision to store/print the correct information.

- Use only the Fan Extended Tachometer registers on IT871[68]F for now;
this gives us correct data for IT8705/IT8712F again.

config(8) glue for Token-Ring and TROPIC drivers.

Several things:
* Rearrange the speed mapping table and adjust the code so that the highest
rate can actually be used. Previously we ended up rounding up slightly
lower speeds and then losing because set_params couldn't set the mode
back to the current one.
* Allow 260 as a valid I/O address, since the SB1 can be jumpered to this.
* Change the MPU-401 code so it can be attached as a separate device.
(XXX Really, the SB code ought to just attach a subdevice itself.)
* Do not attach an OPL on the SB1. Writing to the OPL registers at
SB_base+0 on this card wedges my machine.
(XXX Should we access it at 388 instead? The Creative web site claims
that this board *does* have an OPL2, but I haven't played with this
extensively.)
* Allocate the SB DMA channels at open time, rather than attach time, so
that a single DRQ can be used for multiple cards (if only one is in use
at a given time).
(XXX Let me tell you why this is a horrible hack. If the ISA DMA code
tries to allocate a bounce buffer after boot time, it will generally fail,
because there is no contiguous memory below 16MB and the code to allocate
contiguous pages doesn't know how to move things around. Now, we
shouldn't ever be using bounce buffers here, because we use
isa_dmamem_alloc(). So we just turn off BUS_DMA_ALLOCNOW and we don't
actually try to. That's cool, and it even works, but isa_dmamem_alloc()
has the same problem. It just happens that we allocate the ring buffers
at boot time, and whenever we reallocate them (due to the buffer size
changing), we just deallocated the previous (contiguous) buffer, so we get
lucky. This is absolutely disgusting and needs to be fixed.)

Shuffle wd/wdc driver files around (via repository copies). wdc
now lives in dev/ic, wd now lives in dev/ata. there's now a 'ata'
interface attribute defined in conf/files, but wdc can't go there
yet because some ports still use private versions based on the old
ISA version.

ast, boca, and rtfps are not ttys, but rather "busses". Similarly,
the lpt doesn't export a tty-like interface, so it's dull, too.

Move the we driver at the begining of ethernet board, other board's probe

XXX All these probes sould be reordered after the release, with invasive

an isa 3c509 masquerading as an eisa device (use ep* at eisa? slot ? in
your kernel config file to catch this one).

Working WD7000 and TMC-7000 driver, from Julian Highfield, with additional work by me.
Needs some refinement, but it works.

Various, including:
* Display as much revision info as we can get.
* Fix a race condition that could cause interrupts to be lost.
* Handle `out of mailbox' conditions (much) more gracefully.
* Schedule timeouts more safely.
* Add diagnostic code to (correctly) detect if a CCB times out before its
outgoing mailbox is emptied.

adjust to deal with expression support for optional file specs

change the name of com's attachment to commulti, and provide flags
for that and the isa attachment in com.h (in addition to the flag for
the presence of 'com' itself).

New device attachment scheme:

- split softc size and match/attach out from cfdriver into
a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.

the i386 port no longer attaches isa, eisa, and pci at root.

Add support for Nuvoton NCT5104D GPIO chips, as found on PC Engines APU
systems. From Andrew Doran in PR kern/54648.

Merge isaki-audio2 branch, the overhaul of audio subsystem.
- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency
conversions are completely handled in the upper layer. So the hard-
ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
- Obsoletes query_encoding and add query_format instead.
- Obsoletes set_params and add set_format instead.
- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).

- Invalidate voltage sensors if data returned is 0xff.

- Use the Super I/O Global Configuration Registers Chip ID[12] and Device

config(8) glue for Token-Ring and TROPIC drivers.

Several things:
* Rearrange the speed mapping table and adjust the code so that the highest
rate can actually be used. Previously we ended up rounding up slightly
lower speeds and then losing because set_params couldn't set the mode
back to the current one.
* Allow 260 as a valid I/O address, since the SB1 can be jumpered to this.
* Change the MPU-401 code so it can be attached as a separate device.
(XXX Really, the SB code ought to just attach a subdevice itself.)
* Do not attach an OPL on the SB1. Writing to the OPL registers at
SB_base+0 on this card wedges my machine.
(XXX Should we access it at 388 instead? The Creative web site claims
that this board *does* have an OPL2, but I haven't played with this
extensively.)
* Allocate the SB DMA channels at open time, rather than attach time, so
that a single DRQ can be used for multiple cards (if only one is in use
at a given time).
(XXX Let me tell you why this is a horrible hack. If the ISA DMA code
tries to allocate a bounce buffer after boot time, it will generally fail,
because there is no contiguous memory below 16MB and the code to allocate
contiguous pages doesn't know how to move things around. Now, we
shouldn't ever be using bounce buffers here, because we use
isa_dmamem_alloc(). So we just turn off BUS_DMA_ALLOCNOW and we don't
actually try to. That's cool, and it even works, but isa_dmamem_alloc()
has the same problem. It just happens that we allocate the ring buffers
at boot time, and whenever we reallocate them (due to the buffer size
changing), we just deallocated the previous (contiguous) buffer, so we get
lucky. This is absolutely disgusting and needs to be fixed.)

Mods for ESP406/FAS408 ISA SCSI driver (from Eric S. Hvozda; PR#3581)

Change the interface between high and lowlevel audio drivers again:
Set the encoding parameters slightly differently.
Remove the SW encoding/decodinf functions from this interface
and move them to the audio_parameter struct; this is both more efficient
and flexible.

New version of com driver. Uses a different queueing mechanism and a split
hardware/software interrupt mechanism for improved performance. Many odd
protocols bugs also fixed.

New ARP system, supports IPv4 over any hardware link.

Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

Move the aha ISA probe functions into a separate file.

New cyclades driver from Timo Rossi

Use bus.h.

Update.

New version, with changes from Justin Gibbs and Noriyuki Soda.

Make the MI LANCE driver standalone, and use cfattach to resolve
naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.

Break up ISA LANCE driver into ISA and PCI front-ends.

Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.

Add "iy" driver for Ethernet ISA boards using the Intel i82595 chip, e.g.
(and only tested on) Intel Etherexpress PRO. Should work on any i82595 ISA
board which uses an EEPROM for config information; NETBLKID not yet supported.
TODO: change to BUS interface, add multicast support.

Break up the ep driver into isa, eisa, and pci front-ends and a
bus-independent core driver. Tested on all three bus types, including
an isa 3c509 masquerading as an eisa device (use ep* at eisa? slot ? in
your kernel config file to catch this one).
XXX Driver still needs to be converted to <machine/bus.h>

Working WD7000 and TMC-7000 driver, from Julian Highfield, with additional work by me.
Needs some refinement, but it works.

Various, including:
* Display as much revision info as we can get.
* Fix a race condition that could cause interrupts to be lost.
* Handle `out of mailbox' conditions (much) more gracefully.
* Schedule timeouts more safely.
* Add diagnostic code to (correctly) detect if a CCB times out before its
outgoing mailbox is emptied.

adjust to deal with expression support for optional file specs

change the name of com's attachment to commulti, and provide flags
for that and the isa attachment in com.h (in addition to the flag for
the presence of 'com' itself).

New device attachment scheme:

- split softc size and match/attach out from cfdriver into
a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.

the i386 port no longer attaches isa, eisa, and pci at root.

make ISA bus match/attach, and sub-device configuration machine-independent.

Add the "ahe" driver, autoconfiguration support for the aic7xxx-based
Adaptec 2[78]4x SCSI controllers, from Michael Graff <explorer@flame.org>.
Fixes PR #1594 from Noriyuki Soda <soda@sra.co.jp> in a different way.

Add support for the 3c59x (pci) cards in the 3c5x9 driver. In addition
add the necessary bits for the 3c589 (pcmcia) card without adding any
of the pcmcia framework.

GUS audio driver from John Kohl.

uncomment cy driver spec; i386 conf.c needs the header file.

Fix nits from Mike Long <mike.long@analog.com> PR#996

Change `needs-count' to `needs-flag'.

Correct a couple of things, and add a `fe' device.

if_le conflicts with the Alpha; move description back to i386

Remove Token Ring support.

Add support for Nuvoton NCT5104D GPIO chips, as found on PC Engines APU
systems. From Andrew Doran in PR kern/54648.

Merge isaki-audio2 branch, the overhaul of audio subsystem.
- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency
conversions are completely handled in the upper layer. So the hard-
ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
- Obsoletes query_encoding and add query_format instead.
- Obsoletes set_params and add set_format instead.
- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).

Some file paths are changed:
- dev/audio.c -> dev/audio/audio.c (rewritten)
- dev/audiovar.h -> dev/audio/audiovar.h
- dev/audio_dai.h -> dev/audio/audio_dai.h
- dev/audio_if.h -> dev/audio/audio_if.h
- dev/audiobell.c -> dev/audio/audiobell.c

Add the finsio(4) driver. This driver supports the Hardware Monitor
device in the Fintek LPC Super I/O chips, this includes the following
list:

- F71805F
- F71806F
- F71862FG
- F71872F
- F71882
- F71883F

This has been adapted from the fins(4) driver available in OpenBSD, which
only supported F71805F.

Tobias Nygren <tnn> and myself added support for the other chips; thanks go
to Tobias for testing the driver with a Fintek F71882 chip.

Certain misguided people have complained, NetBSD only runs rare or
"retro" computers, but NetBSD also runs a growing number of rare
and retro add-on cards. With this patch, NetBSD supports the IDEC
Supervision/16, a black&white image capture board for the 16-bit
ISA bus. Approximate date of manufacture: 1991. Total instances
known to be in use throughout the world: one.

Coming soon; isvctl(8), the utility program for capturing 8-bit,
512x480 images at speeds of up to 6 frames per second.

Rename it(4) to itesio(4) to accomodate for the following changes:

- The driver now uses the Super I/O address port as port argument in
the configuration file. The Environmental Controller base address is
fetched by the Super I/O EC LDN configuration registers.

- Invalidate voltage sensors if data returned is 0xff.

- Use the Super I/O Global Configuration Registers Chip ID[12] and Device
Revision to store/print the correct information.

- Use only the Fan Extended Tachometer registers on IT871[68]F for now;
this gives us correct data for IT8705/IT8712F again.

Inspired by the smsc(4) driver. The UPDATING file has been updated to
reflect the rename.

machines, the keyboard controller will not pass this test, but if you
attach anyway, it works fine. Note that this test is specifically
disabled in ic/pckbc.c, but given that it seems to work fine on other
machines, leave it defaulted to on.

Allow to enable the game port on an ES1888, in case the firmware didn't
this. (Otherwise we still rely on the firmware having mapped the sound
related registers.)
Limit this to the "isa" attachment for now because this is the only
one I'm able to test.
Attach the "joy" device directly at "ess" to make sure the port is
enabled before the "joy" probe/attach.
This makes the joystick port usable on a "PWS" alpha (Miata).

the attachment somewhat for better readability; also g/c detach support code

cleanup old lpt(4) attachment, and glue ppbus in so that they can coexist:

"attach radio at radio":
using one word as both attribute and device doesn't work well,
radio.c is pulled in even with no such device in the configuration,

- convert usage of "defopt" to "defflag" where the relevant option does
not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups

move dev/isa/cs89x0{.c,{var,reg}.h} into dev/ic

Enable the imported ISDN4BSD based ISDN subsystem.

This is the kernel part (userland to follow soon) of the latest (and
very probably last) release (version 0.96) of ISDN4BSD. ISDN4BSD has a
homepage at http://www.freebsd-support.de/i4b/.

It gives the user various ways to use the isdn connection: raw data (via
the i4brbch "raw b-channel" device), ppp (via the isp "isdn PPP" device),
voice/answering machine (the i4btel "telephone" device) and ip over isdn
(the ipr device, "IP over raw ISDN").

Supported are a bunch of common and older cards, more to be added soon
after some cleanup. Currently only the european E-DSS1 variant of the
ISDN D channel protocol is supported.
