Remove ISDN4BSD (I4B) from HEAD as it is not MPSAFE and
parts relied on the now removed NET_NEEDS_GIANT.
Most of I4B has been disconnected from the build
since July 2007 in HEAD/RELENG_7.
This is what was removed:
- configuration in /etc/isdn
- examples
- man pages
- kernel configuration
- sys/i4b (drivers, layers, include files)
- user space tools
- i4b support from ppp
- further documentation

The implementation has been made from -scratch by us, based on reverse engineering of the Linux driver provided -by AVM GmbH and available in ftp.avm.de. Cubical Solutions Ltd offers -this implementation for the BSD community free of charge and assuming -absolutely no liabilities whatsoever. Feel free to modify the -implementation any way you see fit, but please retain our one-liner -copyright statement somewhere in the comment headers in the capi and -iavc driver modules. - -That said, the attached tarball is i4b-00.96.00-beta with our -modifications integrated, and the diff contains all modifications we -have made to the original (including the new capi files). Our mods add -pseudo-device i4bcapi, which attaches to i4b layer 4, and device iavc0, -which implements a link layer driver for AVM's active B1 and T1 adapters -for i4bcapi. There are also a couple of related improvements to isdnd, -and a number of modifications to isdnd and layer 4 to implement support -for up to 30 channels per adapter (for primary rate use). - -We have developed the software explicitly for our telephony application, -to be used with AVM's T1 adapters, and the implementation has been -tested primarily with this functionality in mind. There may be -interesting side effects with eg. the ipr and isppp drivers; we do not -use them and therefore their testing has been cursory at best. The -i4btel driver works well with the T1 (our primary use), and the i4brbch -driver has been verified to work with T1, T1-B and B1 adapters (ftp'd -some files over a dialup PPP connection with each adapter). Only the PCI -versions of the adapters (equipped with the AMCC DMA controller) are -supported, although the basics (PIO mode communication) for the older -ISA model support is in place, so only the bus attachment modules should -be required to support the older hardware. - -All of the AVM active adapters use downloadable firmware, which is not -included in the attached package. The firmware files (t1.t4, t1b.t4, -b1.t4) can be found from ftp.avm.de in adapter specific subdirectories, -or from the CDs provided with the adapters (in directory -'cardware/firmware'). - -Our primary development platform is our own embedded build (we call it -'ebsd') based on FreeBSD 4.2-RELEASE. The implementation has also been -tested on standard FreeBSD 4.2-RELEASE system. The implementation should -not contain any FreeBSD (or even FreeBSD release) specific issues, but -it has not been tested or even compiled on any other platforms; -specifically, only the FreeBSD overinstall.sh script is modified to -install the capi/iavc support in the kernel source tree. - -This code is not under active development here since the functionality -we use (i4btel, T1) has been working since the beginning of March. We -are also not planning on any further development (no need seen at this -point), but I am naturally interested on whatever bugs and development -ideas pop up on the community and will keep a keen eye on the isdn -mailing list. I personally may be available for consultation, debugging -and possibly development projects, but with notable reservations on my -time (the current IT industry recession seems to be pushing even more -work for us, which tends to keep us pretty busy these days). - -Here are some specific technical notes: - -* isdnd supports new keyword 'firmware=</path/to/file>' in section -'controller'. This keyword is supported for all controller types, and -causes I4B_CTRL_DOWNLOAD ioctl to be invoked with the specified file as -an argument. In systems equipped with both active and passive adapters, -and the passive cards being detected first, dummy 'controller' entries -are required for the passive cards to get the correct firmwares to -correct adapters. (I hope you did not have other uses for this ioctl in -mind?) - -* isdnd supports new keyword 'clone=<entry name>' in section 'entry'. -This causes the entry to be copied from the existing named entry. At -least entry specific 'name' and 'usrdeviceunit' values should be -specified after a 'clone'. (Makes configuring 30 or 60 entries way much -easier.) - -* a bug in i4btel driver read routine corrected. The conditions in the -while() clause caused the receive queue to be referenced before checking -if a channel is connected, leading to kernel panic (do a 'dd -if=/dev/i4btel0 of=/dev/null' on an unconnected tel device, panic will -follow). Correction was to reorder the while clause conditions to check -for connectedness first. - -* isdnd and i4b layer 4 support up to CHANNELS_MAX (=30) channels per -adapter. The msg_ctrl_info_req_t message reports the number of channels -provided by the adapter, the number is stored in the nbchan field of the -controller state structure. The fixed stateb1 and stateb2 entries in -controller state stuctures are replaced with an array, and all fixed -references there are replaced with loops up to nbchan. Passive stack -layer 1 and 2 are not modified, layer 3 sets this field to fixed value 2 -for all adapters (but it could be delegated to the layer 1 driver's -attach request). - -* the i4bcapi driver maps i4b channels to logical channels identified -with PLCI/NCCI values in the CAPI protocol using the sc_bchan[] array. -The PLCI/NCCI handling is merged in the channel mapping and is greatly -simplified from the reference state machine model, because in practice -there can be only one PLCI/NCCI per channel active at any given time. - -* the i4bcapi driver does not provide any kind of user level interface -(such as the /dev/capi20 interface provided by the linux driver), but -could relatively easily be extended to do so (and if done, interface -compatibility with the linux implementation would probably be a good -goal). - -* there are some gritty details in the iavc driver, inherited from the -linux code. Despite us being a legitimate company in the telecom -business, AVM failed to produce any programming reference material for -us (at least in a reasonable time frame), so some guesswork remains due -to classic reverse engineering process (particularly there are a few -magic numbers in the card initialization sequence whose meaning I do not -know). - -* pseudo-devices i4bq931, i4bq921 and some passive stack layer 1 driver -(such as iwic) are required to compile, as the required ctrl_desc[] -array is in layer 3, which requires layer 2, which requires layer 1. -Some architectural cleanup would come in handy here, but we did not want -to start making any major changes (and we use iwic in test setups -anyway, so we simply always compile it in). - -To summarize: unpack, overinstall, add the following lines (with the -usual passive stack configuration including at least one L1 driver) to -your kernel configuration file: - -pseudo-device "i4bcapi" -device iavc0 - -...and the following to your isdnd.rc: - -controller -firmware = /usr/lib/isdn/b1.t4 - -...compile your new kernel, make sure the firmware file is in -/usr/lib/isdn, and your B1 adapter should boot up and Just Work (tm). If -you have multiple adapters, you need a 'controller' section for each to -have them loaded and booted on isdnd startup. - -Have fun -- and let me know if there are any complications, or if I can -be of further assistance, - - - Juha --- -Juha-Matti Liukkonen, Cubical Solutions Ltd -Phone: +358(0)405280142 -Email: jml@cubical.fi diff --git a/sys/i4b/capi/capi.h b/sys/i4b/capi/capi.h deleted file mode 100644 index c6dc9e8..0000000 --- a/sys/i4b/capi/capi.h +++ /dev/null @@ -1,130 +0,0 @@ -/*- - * Copyright (c) 2001 Cubical Solutions Ltd.
