2018-03-01timer: Introduce osmo_clock_gettime to override clock_gettimePau Espin Pedrol1-1/+2

2017-11-17conv_acc: Our code requires SSSE3, not just SSE3Harald Welte1-5/+5
The accelerated convolutional decoder uses SSSE3 instructions such as PSIGNW (via _mm_sign_epi16) which go beyond what SSE3 offers. So let's make sure we use the right compiler flag (-mssse3) and also the right runtime check. Without this patch, we would use illegal instructions e.g. on Opteron Gen3 such as Opteron 2427, which are also used as build.opensuse.org build hosts (build31 through build36) where we wouldn't pass "make check" as a result.

2017-10-30Move additional libraries to appropriate placeMax1-3/+3
According to https://www.gnu.org/software/automake/manual/automake.html#Libtool-Flags the libraries supposed to be added to *_LDADD or *_LIBADD while *_LDFLAGS should contain additional libtool linking flags. Previously we used both. Let's unify this and move all the libraries into proper automake variable. While at it - also add libosmocore.la for tests to LDADD since all the tests link against it anyway. Change-Id: Ia657a66db75df831421af5df1175a992da5ba80f

2017-10-15Rename 'statistics.c' to 'counter.c'Harald Welte1-1/+1
With stat_item, stats.c and stats_statsd.c, it is becoming a bit difficult to understand file naming. Also, the 'statistics.c' file actually only contained osmo_counter handling, so let's rename it to counter.c altogether. Change-Id: I2cfb2310543902b7da46cb15a76e2da317eaed7d
2017-07-10Add pseudo-random bit sequence generator to libosmcooreHarald Welte1-1/+1
These PRBS sequences are specified in ITU-T O.150. They are typically used as test data to be transmitted for BER (bit error rate) testing. Change-Id: I227b6a6e86a251460ecb816afa9a7439d5fb94d1
2017-06-19src/Makefile.am: fix build: use AM_CFLAGS, not CFLAGSNeels Hofmeyr1-4/+4
This allows passing 'make CFLAGS+="..."' without breaking the build. Suggested-by: zecke Change-Id: I0628a9c739cded771605f5c55df7f21cb07beb3b
2017-06-19core/conv: use proper filenamesVadim Yanitskiy1-8/+8
We already have generic convolutional transcoding implementation written by Sylvain Munaut and named 'conv.c', so 'viterbi_*' names looked a bit confusing. Let's use a single naming scheme for Viterbi related code. Change-Id: I61062a8d1fbf5f5fc85b4fac58dc4e9fa8b5ef90
2017-05-29core/conv: do not mix up AVX and SSE codeVadim Yanitskiy1-2/+15
According to GCC's wiki: If you specify command-line switches such as -msse, the compiler could use the extended instruction sets even if the built-ins are not used explicitly in the program. For this reason, applications that perform run-time CPU detection must compile separate files for each supported architecture, using the appropriate flags. In particular, the file containing the CPU detection code should be compiled without these options. So, this change introduces a separate Viterbi implementation, which is almost the same as previous one, but is being compiled with -mavx2. This implementation will be only used by CPUs with both SSE and AVX support: SSE3 and AVX2: viterbi_sse_avx.c SSE3 only: viterbi_sse.c Generic: viterbi_generic.c Change-Id: I042cc76258df7e4c6c90a73af3d0a6e75999b2b0
2017-05-29core/conv: rename viterbi_gen.c to viterbi_generic.cVadim Yanitskiy1-1/+1
Let's avoid confusion with generated files which have ending with _gen.* as well. Change-Id: I3ecd8f9e73c05236f2cdc186f58b3d0ba552283f
2017-05-24core/conv: add x86 SSE support for Viterbi decoderTom Tsou1-0/+6
Fast convolutional decoding is provided through x86 intrinsic based SSE operations. SSE3, found on virtually all modern x86 processors, is the minimal requirement. SSE4.1 and AVX2 are used if available. Also, the original code was extended with runtime SIMD detection, so only supported extensions will be used by target CPU. It makes the library more partable, what is very important for binary packages distribution. Runtime SIMD detection is currently implemented through the __builtin_cpu_supports call.

2017-05-17add libpseudotalloc as super-simplistic talloc replacementHarald Welte1-0/+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

2017-04-11core/conv: implement optimized Viterbi decoderTom Tsou1-1/+2
Add a separate, faster convolution decoding implementation for rates up to N=4 and constraint lengths of K=5 and K=7, which covers the most GSM code uses. The decoding algorithm exploits the symmetric structure of the Viterbi add-compare-select (ACS) operation - commonly known as the ACS butterfly. This shift-register optimization can be found in the well-known text by Dave Forney. Forney, G.D., "The Viterbi Algorithm," Proc. of the IEEE, March 1973. Implementation is non-architecture specific and improves performance on x86 as well as ARM processors. Existing API is unchanged with optimized code being called internally for supported codes. The original code was relicensed under GPLv2-or-later with permission of copyright holder - Tom Tsou. Change-Id: I74d355274b4176a7d924f91ef3c96912ce338fb2

2016-12-09Implement GSMTAP log targetHarald Welte1-1/+1
This target wraps the to-be-logged string (With metadata) into a GSMTAP packet and sends it to the configured destination address. Change-Id: I9a7e72b8c9c6f6f2d76d1ea2332dcdee12394625
2016-09-22add osmo_gettimeofday as a shim around gettimeofdayNeels Hofmeyr1-1/+1
This allows feeding a custom time for unit tests by overriding osmo_gettimeofday. Change-Id: Ic7a81a6eb51f27fe452962b91f2eae2070d87089
2016-06-16Add Finite State Machine abstraction codeHarald Welte1-1/+1

2016-02-18Add T4 bit map compression routinesMax1-1/+1
Add bit map encoder and decoder functions: decoder is fully functional while encoder is good enough for testing - no backtracking to find the best possible compression is implemented. If somebody is willing to implement MS side of EDGE than this has to be expanded. Add corresponding tests. N. B: the encoding is implemented according to ETSI TS 44.060 which is slightly different from T4 used for fax according to CCITT G31D (RFC 804).

2015-12-05remove our internal copy of talloc, use system libtallocHarald Welte1-11/+5
Shipping our own private copy of talloc was a good idea in 2008, when it was not readily available on most target platforms. Today, the situation is quite different, as it is a standard library on major Linux distributions.
2015-11-26stats: Move statsd related code into a separate fileJacob Erlbeck1-1/+1
This commit moves the stats specific code parts into stats_statsd.c while keeping the generic parts in stats.c. The code in stats.c no longer contains references to statsd symbols. Note that the VTY code still needs to know about every stats reporter backend. Sponsored-by: On-Waves ehf
2015-10-29stats: Add the reporting frameworkJacob Erlbeck1-1/+1
This commit provides the stats reporting framework that can manage several types of measurement reporters. Initially support for rate_ctr and the statsd protocol is included. Sponsored-by: On-Waves ehf
2015-10-28stats: Add stat_item for value monitoringJacob Erlbeck1-1/+1
This commit adds instrumentation function to gather measurement and statistical values similar to counter groups. Multiple values can be stored per item, which can be retrieved in FIFO order. Getting values from the item does not modify its state to allow for multiple independant backends (e.g. VTY and statd). When a new value is set, the oldest value gets silently overwritten. Lost values are skipped when getting values from the item. Sponsored-by: On-Waves ehf

2014-04-17backtrace: Speculative fix for FreeBSD10.0 and execinfo.hHolger Hans Peter Freyther1-1/+2
FreeBSD 10.0 ships an execinfo.h but one needs to link to an additional library for the backtrace functions. Check if there is a backtrace symbol in libexecinfo and if so link to that library.
2013-03-03cygwin: Link many libraries with -no-undefined to create a dllHolger Hans Peter Freyther1-2/+2
Only the Gb library relies on having undefined references to a symbol that needs to be provided by the host application. For all other libraries we can link with -no-undefined.
