adapter (and some workalikes). Also add man pages and a wicontrol
utility to manipulate some of the card parameters.
This driver was written using information gleaned from the Lucent HCF Light
library, though it does not use any of the HCF Light code itself, mainly
because it's contaminated by the GPL (but also because it's pretty gross).
The HCF Light lacks certain featurs from the full (but proprietary) HCF
library, including 802.11 frame encapsulation support, however it has
just enough register information about the Hermes chip to allow someone
with enough spare time and energy to implement a proper driver. (I would
have prefered getting my hands on the Hermes manual, but that's proprietary
too. For those who are wondering, the Linux driver uses the proprietary
HCF library, but it's provided in object code form only.)
Note that I do not have access to a WavePOINT access point, so I have
only been able to test ad-hoc mode. The wicontrol utility can turn on
BSS mode, but I don't know for certain that the NIC will associate with
an access point correctly. Testers are encouraged to send their results
to me so that I can find out if I screwed up or not.
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.

only worked for configurations with "swap on generic".
usr.sbin/config/config.y:
- ignore all "swap [on] device ...' specifications except for
warning about them. They haven't done anything related to swap
for almost 4 years, and were previously silently ignored,
except for "swap on generic" which stopped swap${KERNEL}.c
from being generated. Code to support swapping is now deader
than before.
usr.sbin/config/mkswapconf.c:
- don't generate a dummy setconf() function in swap${KERNEL}.c.
sys/i386/conf/files.i386:
- swapgeneric.c is now standard. It should be merged into autoconf.c
so that it doesn't conflict with swap${KERNEL}.c for kernels named
"generic".
sys/i386/i386/autoconf.c:
- don't call setroot() for mfs roots. Since setroot() doesn't do anything
harmful, this was just a waste of time, except possibly for booting with
-a it may have helped prevent an undesireable call to setconf() by
finding a bogus rootdev.
- honor -a for ffs roots. -a now overrides all other ways of specifying
the root device. Previously, -r had precedence over -a, and the -a
handling was usually a no-op.
- don't honor -a for non-ffs roots, since it would currently just get in
the way of a clean panic.
sys/i386/i386/swapgeneric.c:
- don't declare things that are now always declared in swap${KERNEL}.c.
Don't decide things that are now decided in autoconf.c. Code to
support the "generic" case is now dead instead of useless.
perform a cleanup/unifdef sweep over it to tidy things up. The atapi
code is permanently attached to the wd driver and is always probed.
I will add an extra option bit in the flags to disable an atapi probe on
either the master or slave if needed, if people want this.
Remember, this driver is destined to die some time. It's possible that
it will loose all atapi support down the track and only be used for
dumb non-ATA disks and all ata/atapi devices will be handled by the new
ata system.
ATAPI, ATAPI_STATIC and CMD640 are no longer options, all are implicit.
Previously discussed with: sos
Sense ${DEBUG} to decide on building kernel.debug or not.
Use a common install and install.debug target to minimize duplication.
(I deleted the ELF transition kernel warning, it was getting dated..)

Modify targets for debug kernels: when -g was specified, make will
now build a debug kernel called kernel.debug, and create a stripped
version called kernel at the same time. The two targets install and
install.debug are otherwise unchanged.
Requested-by: dillon
Update man page accordingly.
2. Config complains if you use -g:
Debugging is enabled by default, there is no ned to specify the -g option
3. Config warns you if you don't use -s:
Building kernel with full debugging symbols. Do
"config -s BSD" for historic partial symbolic support.
To install the debugging kernel, do make install.debug
(BSD was the name of the config file I used; I print out the same
name).
4. Modify Makefile.i386, Makefile.alpha, Makefile.pc98 and config to
work if a kernel name other than 'kernel' is specified. This is
not absolutely necessary, but useful, and it was relatively easy.
I now have a kernel called /crapshit :-)
5. Modify Makefile.i386, Makefile.alpha, Makefile.pc98 "clean" target
to remove both the debug and normal kernel.
6. Modify all to install the stripped kernel by default and the debug
kernel if you enter "make install.debug".
7. Update version number of Makefiles and config.
Networks Tigon 1 and Tigon 2 chipsets. There are a _lot_ of OEM'ed
gigabit ethernet adapters out there which use the Alteon chipset so
this driver covers a fair amount of hardware. I know that it works with
the Alteon AceNIC, 3Com 3c985 and Netgear GA620, however it should also
work with the DEC/Compaq EtherWORKS 1000, Silicon Graphics Gigabit
ethernet board, NEC Gigabit Ethernet board and maybe even the IBM and
and Sun boards. The Netgear board is the cheapest (~$350US) but still
yields fairly good performance.
Support is provided for jumbo frames with all adapters (just set the
MTU to something larger than 1500 bytes), as well as hardware multicast
filtering and vlan tagging (in conjunction with the vlan support in
-current, which I should merge into -stable soon). There are some hooks
for checksum offload support, but they're turned off for now since
FreeBSD doesn't have an officially sanctioned way to support checksum
offloading (yet).
I have not added the 'device ti0' entry to GENERIC since the driver
with all the firmware compiled in is quite large, and it doesn't really
fit into the category of generic hardware.
Well, better late than newer, but things has been hectic
around here, sorry for the long delay.
DMA support has been added to the ATA disk driver.
This only works on Intel PIIX3/4, Acer Aladdin and Promise controllers.
The promise support works without the BIOS on the board,
and timing modes are set to support up to UDMA speed. This
solves the problems with having more than one promise controller
in the same system.
There is support for "generic" DMA, that might work on other
controllers, but now you have been warned :)
More chipset specific code will come soon, I have to find testers
with the approbiate HW, more on that when I have it ready.
The system now uses its own major numbers, please run MAKEDEV
with the devices you need (ad?, acd?, afd?, ast?).
For now the disk driver will also attach to the old wd major
so one can at least boot without this step, but be warned, this
will eventually go away. The bootblocks will have to be changed
before one can boot directly from an "ad" device though.
Fixed problems:
All known hang problems should be solved
The probe code has been sligthly changed, this should solve
the reports I have lying around (I hope).
Hangs when accessing ata & atapi device on the same channel simultaniously.
A real braino in ata_start caused this, fixed.
As usual USE AT YOUR OWN RISK!!, this is still pre alpha level code.
Especially the DMA support can hose your disk real bad if anything
goes wrong, agaiin you have been warned :)
But please tell me how it works for you!
Enjoy!

bootblocks in order to boot the kernel after this! Also note that this
change breaks BSDI BSD/OS compatibility.
Also increased default NKPT to 17 so that FreeBSD can boot on machines
with >=2GB of RAM. Booting on machines with exactly 4GB requires other
patches, not included.

- Removed the note that the VESA option cannot be used on the SMP system;
this is not true.
- Moved the option VESA to more appropriate place.
