This change introduces a modified version of gprsdecode utility,
which is intended to decode the GPRS burst captures and forward
decoded packets to the GSMTAP sink.
The following modifications were made:
- use shared libosmocoding library for GSM 05.03 coding;
- use optget for command line options parsing;
- use a single application select loop;
- use GNU automake as the build system;
- add regression tests (GNU autotest);
- clean up and comment the code;
- add license headers;
The code is based on work of SRLabs:

This app is similar to the osmocon, but designed to
connect L2 & L3 apps with SDR transceiver insted of
obsolete Calypso based hardware.

This patch implements a virtual physical layer replacing the air
interface. The purpose is to get rid of the hardware requirements
and be able to start testing and implementing layer 2 communication
functionality on one machine. Multicast sockets are used to enable
bidirectional communication between the BTS and the MS process.
The GSMTAP protocol designed for wireshark capturing is used to
encapsulate the payload on the virtual physical layer.
The virtual physical layer on the osmocom-bb side implements the
L1CTL interface to the layer23 apps like mobile.
* Working mcast socket communication and extraction of its
functionality.
* Basic handlers for file descriptor callbacks from incoming L1CTL
messages and extraction of that functionality to a l1ctl socket class.
* Multiplexing to different routines depending on incoming L1CTL
message type.
* Uses virt_um and osmocom_mcast_sock implementation from osmo-bts
virt-phy.
* Ecapsulation and parsing methods to and from GSMTAP messages.
* Basic handlers for file descriptor callbacks from incoming mcast
messages on the virtual um.
* Multiplexing to different channel routines based on GSMTAP header
channel type.
* Example configuration for l23 app mobile using virtual test sim.

We are just interested in the loaders here, no other applications needed.
Split it from the compal-based phones. Add mt62xx as first user.
Based on a patch by steve-m, but cleaned up and seperated from compal/calypso.

This patch changes include paths to get osmocom-bb working with
the current libosmocore tree.
Among all these renames, you can notice several tweaks that I
added on purpose, and that require some explanation, they are:
* hexdump() in osmocon.c and osmoload.c has been renamed to avoid
clashing with hexdump() defined in libosmocore.
* gsmmap now depends on libosmogsm. Actually I had to cleanup
Makefile.am because I was experiencing weird linking problems,
probably due to a bug in the autotools. With the change included
in this patch, I got it compiled and linked here correctly.
This patch has been tested with the phone Motorola C123 and the
following images files:
* firmware/board/compal_e88/hello_world.compalram.bin
* firmware/board/compal_e88/layer1.compalram.bin
Using the osmocon, bcch_scan and mobile tools.

People using a GNU/Linux toolchain can end up in trouble when
gsmtap_util.c is including network header files. Hint autoconf
that there is no sys/select.h
|
|
The gnuarm.com toolchain works fine but is very old. And although
it is based on newlib, the tuple that we used to configure for was
arm-elf-linux, which is bogus since we aren't building for Linux.
This patch optimizes for the CodeSourcery G++ Lite 2010.09 ARM EABI
toolchain instead, and for libosmocore installation it assumes that
the new toolchain was unpacked next to the old one. Download it here:
http://www.codesourcery.com/sgpp/lite/arm/portal/release1592
(The Linux Installer seems not to work reliably so I recommend the
TAR.)
Since CC is detected by configure when the host tuple points to a sane
toolchain we shouldn't hard-code the gnuarm.com compiler.
The patch autodetects arm-elf-gcc installed in PATH, and uses arm-elf
as prefix if it is found. Otherwise, it defaults to arm-none-eabi.
make CROSS_HOST=arm-xyzzy can be used to override on the command line.

Several toolchains are missing syscalls provided by the libc used. For example,
if the newlib was build with the configure flag "--disable-newlib-supplied-syscalls".
To prevent the configure check for things like "_exit" in osmocom
the CFLAGS+="-nostartfiles -nodefaultlibs" helps a lot.

Append $(HOST_CONFARGS) to ./configure scripts for 'host' applications.
This allows e.g. cross-compiling on an x86 build system for an OpenMoko
gta0x host, using an invocation such as:
$ make HOST_CONFARGS="--host=arm-angstrom-linux-gnueabi"

The vty code cannot be cross-compiled to the target yet, we need to
disable building it.
|
|
* remove linuxlist.h copy and use osmocore
* don't put 'struct gsm_time' into l1ctl packets
* include rx_level and snr for each burst in l1ctl
* properly build libosmocore.a for target
* move gsmtime functions into libosmocore
* move ctype.h to standard location
