saves about 2.2MB under /usr/include/dev/. Discussed on tech-kern@
recently.
I HOPE to get the list right. The headers I left in are ones
used for MI tools and those whose usage I discovered by grep over tree sources.
Feel free to put needed includes back in if you encounter anything which
should not be removed from lists.
This now provides slightly more functionality than the FreeBSD layer1-newbus
interface. It was meant to be a simple change to one header and a few
c files, but the change rippled all through various stuff.
To prevent a change to the kernel<->userland interface right now the kernel
is now lying about card types to userland (but who cares). This will be fixed
when the userland interface changes, after layer 3 <-> layer 4 has been
fixed.
Functional changes:
Provide a clean interface for hardware drivers to attach to the upper
layers. This will need another small change in the B-channel handling
when a similar change to the layer 3 <-> layer 4 interface happens.
Avoid passing indices into global arrays of pointers around, instead pass
the pointers itself. Don't code hardware driver types by predefined magic
numbers (think LKM). Prepare for detachable drivers (think pcmcia).
While there remove some sets of function pointers always pointing to the
same function (meant to be the configurable set of D channel protocol
handlers). It is unlikely another supported D-channel protocol will fit into
that (maximal layer interface) abstraction. When we get support for another
protocol, we will need to come up with a workable interface. Besides, the
old implementation was, uhm, strange.
need an interupt when the hardware hits tx chain end. We switch on one
int per packet sent when we fill up and go into OACTIVE mode.
Measured total interupt savings on large NFS writes: 20%.
- Adjust for the driver to be configured as fdisa
- Add a for the atari correct fd_types array
- Work around the fact that the atari has no machine/conf.h
remove all (legacy) "i4b_" prefixes outside of sys/netisdn.
Prefix all card specific driver support files with the basename
of the driver bus attachement file.
Renamed here:
i4b_isic_isa.c -> isic_isa.c
i4b_avm_a1.c -> isic_isa_avm_a1.c
i4b_daic_isa.c -> daic_isa.c
i4b_itk_ix1.c -> isic_isa_itk_ix1.c
i4b_tel_s08.c -> isic_isa_tel_s08.c
i4b_tel_s016.c -> isic_isa_tel_s016.c
i4b_tel_s0163.c -> isic_isa_tel_s0163.c
i4b_usr_sti.c -> isic_isa_usr_sti.c
This adds support for EtherExpress/16 cards with 16k of RAM, and in the
process adds general support for PIO mode on these cards. This entails
changing the way the i82586 driver handles bus barriers, since it doesn't
allow for strange cases like this.
This has been tested on the i386 port with the 'ix' driver in both
16KB (which was the source of the problem) and 32KB modes, as well
as with the 'ef' driver. I've tested it (briefly) with 'ei' on arm26
as well. In theory, drivers other than 'ix' should follow precisely the
same code paths as before.
the number of partitions is > OLDMAXPARTITIONS. This is better
than silently truncating the label (don't want to silently throw
away partitions when using an old disklabel binary on a label with
> 8 partitions). From Enami Tsugutomo.
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.
support for it and we're configured for separate play and record
DRQs. This makes full-duplex audio work on the Windows Sound System
(found in many Alpha systems).
