* doxygen: enable AUTOBRIEF, drop \briefNeels Hofmeyr2017-06-235-73/+73
| | | | | | | | | | Especially for short descriptions, it is annoying to have to type \brief for every single API doc. Drop all \brief and enable the AUTOBRIEF feature of doxygen, which always takes the first sentence of an API doc as the brief description. Change-Id: I11a8a821b065a128108641a2a63fb5a2b1916e87
* Move NUM_BYTES macro to core libraryMax2017-06-191-1/+1
| | | | | | | | | It's universally useful so it make sense to have it in the shared core: * move macro from libosmocoding to libosmocore * add OSMO_ prefix * add doxygen docs Change-Id: I5386ba3e1f1cc153ba96c29dc71c9075a052aa02
* gsm0503_coding: Mark gsm0503_mcs_{ul,dl}_codes as constHarald Welte2017-06-121-6/+6
| | | | | | | The table describing the various MCS convolutional codes are constant data and should be marked as such. Change-Id: I4918521ee4572a67cbee5f9b49257fc5bfcde511
* gsm0503_interleaving: Mark input arguments as 'const *'Harald Welte2017-06-121-5/+5
| | | | | | | The interleaving/deinterleaving functions were missing 'const' qualifiers on their input data buffers Change-Id: I2118c34a6353167787b23f877f1d81d60151aaf9
* Add doxygen documentation to libosmocodingHarald Welte2017-06-125-30/+414
| | | | | | | This adds the minimum amount of API documentation that we should have on all our code, particularly new code merged into a library. Change-Id: I526804f64313867913574e50e5b9e9205ad3aa74
* gsm0503_{coding,mapping}: Mark input arguments as 'const'Harald Welte2017-06-122-55/+54
| | | | | | | | It is generally our coding style to mark pointers to constant input data as 'const *'. For some reason the gsm0503 coding and mapping was not adhering to this, so let's bring it into compliance. Change-Id: Id8731d7ae6171dff94741b6ddbb95ab5f03bfd4e
* Distinguish between unsupported and invalid MCSMax2017-05-241-6/+9
| | | | | | | | | | | | | | | | | | Previously MCS0 was incorrectly set for some of type1 header values while according to 3GPP TS 44.060 it can only be set for type3. Fix this: * use EGPRS_MCS* constants instead of magic values * do not set MCS0 for reserved bits values in EGPRS header type1 * return different error codes for invalid and unsupported MCS as well as for other decoding errors Note: there's no need to adjust tests because MCS0 decoding is not supported but it's better to explicitly distinguish between unsupported and invalid values nevertheless.

* add libpseudotalloc as super-simplistic talloc replacementHarald Welte2017-05-171-0/+4
| | | | | | | | | | | In tightly embedded builds (--enable-embedded), we want the ability to replace talloc with a very simple heap allocator to avoid the complexity of talloc without modifying all our code that assumes talloc. This will break the hierarchical notion of the allocator, but libosmo{core,gsm,coding,codec} don't rely on that anyway. Change-Id: Ie341034076f242a813f081919dd09d845775ad35
* build: coding/gsm0503: fix build in sep. dir: -I builddirNeels Hofmeyr2017-03-201-0/+1
| | | | | | | | To allow building coding/gsm0503_interleaving.c which includes the generated bit*gen.h (via bits.h), add -I to the builddir include path in order to find the generated bit*gen.h headers there. Change-Id: I0d465bc109765b1315d615243bea6af027afa368
* build: cosmetic: coding: break a CPPFLAGS lineNeels Hofmeyr2017-03-131-1/+3
| | | | | | Matches our general scheme and helps readability of an upcoming patch. Change-Id: I174086a988b51b6e80f3661609069b69a3d41cc7
* libosmocoding: migrate transcoding routines from OsmoBTSVadim Yanitskiy2017-03-077-0/+5553
There are some projects, such as GR-GSM and OsmocomBB, which would benefit from using one shared implementation of GSM 05.03 code. So, this commit introduces a new sub-library called libosmocoding, which (for now) provides GSM, GPRS and EDGE transcoding routines, migrated from OsmoBTS. The original GSM 05.03 code from OsmoBTS was relicensed under GPLv2-or-later with permission of copyright holders (Andreas Eversberg, Alexander Chemeris and Tom Tsou). The following data types are currently supported: - xCCH - PDTCH (CS 1-4 and MCS 1-9) - TCH/FR - TCH/HR - TCH/AFS - RCH/AHS - RACH - SCH Change-Id: I0c3256b87686d878e4e716d12393cad5924fdfa1
