2017-05-29sigProcLib: Fix number of tail bits in random Normal Bursts and zero ↵Alexander Chemeris1-3/+9
Stealing Bits. This bug only affects generation of normal bursts filled with random bits which are used in test mode. It doesn't affect operation of osmo-trx during normal operation. That's why it has stayed unnoticed for so long. Each Normal Burst has 3 tail bits, not 4. Also it's better to set stealing bits to 0 for maximum compatibility. We may want to introduce a selector for each bit whether to set it to 0, to 1 or to a random number. Change-Id: I0377029556c8b681b3ba3b635bf19572b34546ea
2017-05-19radioInterface: Remove UmTRX 'diversity' optionTom Tsou9-406/+16
The 'diversity' option was an experimental 2 antenna receiver implementation for UmTRX. The implementation has not been maintained and current working status is unknown. In addition to code rot, Coverity is triggering errors in the associated code sections. Removal of code cleans up many cases of special handling that were necessary to accommodate the implementation.

2017-05-19cosmetic: Add info about SSE supportPhilipp Maier1-0/+16
The osmo-trx binary outputs no info about its SSE support status. This commits adds some putput that informs about the SSE of the binary and also tells which of the SSE levels the CPU supports. Change-Id: Iacc83fd668c31644e0efb3e18962cf2870ed1daf
2017-05-19buildenv: Split up SSE3 and SSE4.1 codePhilipp Maier9-658/+881
Currently we find SSE3 and SSE4.1 code mixed togehter along with generic code in one file. This introduces the risk that the compiler exidantly mixes SSE4.1 instructions into an SSE3, or even worse into a generic code path. This commit splits the SSE3 and SSE4.1 code into separate files and compiles them with the matching target options. Change-Id: I846e190e92f1258cd412d1b2d79b539e204e04b3
2017-05-19cosmetic: remove code duplicationPhilipp Maier5-35/+49
The ARM and the X86 implementation of the conversion functions share the same, non cpu specific implementation in separate files. This commit removes the code duplication by putting the generic implementation into a convert_base.c, similar to to convolve_base.c Change-Id: Ic8d8534a343e27cde79ddc85be4998ebd0cb6e5c
2017-05-19ssedetect: Add runtime CPU detectionPhilipp Maier6-49/+142
The current implementation can select the SSE support level during compiletime only. This commit adds functionality to automatically detect and switch the SSE support level and automatically switch the Implementation if the CPU does not support the required SSE level. Change-Id: Iba74f8a6e4e921ff31e4bd9f0c7c881fe547423a
2017-05-02cosmetic: Make parameter lists uniformPhilipp Maier2-110/+143
The non-sse implementation and the sse implementation of the convert and convolve functions have different parameter lists. This makes it difficult to use function pointers in order to select the right function depending on the SSE-Level and CPU. This commit uniformizes the parameter lists in preparation for planned runtime cpu detection support Change-Id: Ice063b89791537c4b591751f12f5ef5c413a2d27
2017-05-02buildenv: Turn off native architecture buildsPhilipp Maier1-1/+1
The compiler option -march=native instructs the compiler to auto-optimize the code for the current build architecture. This is fine for building and using locally, but contraproductive when generating binary packages. This commit replaces -march=native with $(SIMD_FLAGS), which contains a collection of supported SIMD options, so we won't loose the SSE support. Change-Id: I3df4b8db9692016115edbe2247beeec090715687
2017-04-10config: Remove OpenBTS style sqlite configurationTom Tsou1-80/+4
OpenBTS relies on reading in configuration values from the OpenBTS.config sqlite3 database. This configuration method is not maintained and not recommended for Osmocom or OpenBTS use. Command line setup is the recommended approach. Note that when the osmo-trx logging mechanism is replaced, the sqlite dependency will be removed. Change-Id: I95d7b771fde976818bee76f89163e72c3a44ecdd

2017-03-28sigProcLib: Constify demodulation functions burst argument.Alexander Chemeris2-10/+10
demodCommon() used to scale input vector in place which changed original data. That's a bad practice and is not really necessary, so I've changed the code to scale burst after it's copied to a new vector during a delay operation. Change-Id: Ic45f71b634e48808356d68925bb9f5783e0bf0d3

2017-03-22Call vectorSlicer() right before packing bits for transmission to osmo-bts.Alexander Chemeris2-3/+3
vectorSlicer() converts soft-bits from -1..+1 to 0..1 while we want to keep SoftVector in -1..+1 mode until the last minute, because at some point we'll want to transmit -1..+1 to osmo-bts instead of converting it from 0..1 back to -1..+1 on the osmo-bts side. Plus it removes code duplication - we call it once instead of twice. Change-Id: Idd6ddd7ac219afb0df055a692632678b66373764
2017-03-22sigProcLib: Slice SoftVector instead of signalVector for GMSK demod.Alexander Chemeris2-26/+22
This makes it similar to 8-PSK demod and also saves a bit of lines ofcode and should give us a tiny improvement in performance. Ideally we need to remove vector slicing at all, because in osmo-bts-trx we convert back to +-1.0 again (actually to +-127, but it doesn't mater). So we should rather transmit +-1.0 values to avoid double conversion. Change-Id: If9ed6f0f80fbe88c994b2f9c3cae91d0d57f4442

2017-03-20sigProcLib: Fix documentation, sync argument names in .cpp and .h files.Alexander Chemeris2-47/+49
Documentation in sigProcLib.h was noticeably out of sync with the actual implementation - e.g. not all arguments were documented and arguments which are already removed are still in the documentation. Also argument names were different between declaration in .h and implementation in .cpp which was confusing. I've fixed this for detect*Burst() functions.

2017-03-07uhd: Increase MC-BTS FPGA clock rate to 51.2 MHzTom Tsou1-10/+13
Addresses following issues where UHD 3.9 and likely other UHD versions would report a master clock (FPGA) rate error. Update MC-BTS FPGA clock for B200 and B210 to 51.2 MHz, which is supported by all UHD versions. Only B200/B210 is supported for MC-BTS operation. https://osmocom.org/issues/1963 https://osmocom.org/issues/1648 ALERT UHDDevice.cpp:548:set_master_clk: Failed to set master clock rate ALERT UHDDevice.cpp:549:set_master_clk: Requested clock rate 3.2e+06 ALERT UHDDevice.cpp:550:set_master_clk: Actual clock rate 5e+06 Change-Id: I78fb2c0959abd0e666628ba39f433162aafb067e

2017-01-19Revert "uhd: Set minimum supported version to 3.9.0"Tom Tsou1-0/+6
This reverts commit 93ca09ea61d044e5f8662b28bf084c808cac4f2c. Ettus Research recommends the use of 3.9 series of UHD releases, but requiring this version has lead to issues with broken OBS and packaged binaries by Debian, Ubuntu, and other distributions.

2016-07-19sigproc: Fix missing 8-PSK tail symbolsTom Tsou1-1/+1
Agilent E4406A measurement of TSC synchronized RF envelope measurement. showed failing power levels at the tail end of EDGE bursts. Regression traced back to following commit. Commit d2b070369dd5341ac42ec091370d8bcd5a8ac5ee "uhd: Correct timing alignment in 8-PSK and GMSK downlink bursts" In the patch, the EDGE burst was delayed one symbol, but erroneously truncated at the tail end causing the failing RF envelope measurement. The missing tail symbol did not appear to affect end-to-end EGPRS tests. This patch corrects the truncation. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-19transceiver: Fix 4 SPS receive TOA valueTom Tsou1-1/+1
The time-of-arrival (TOA) value out of sigProc is specified in symbols or, equivalently, 1 sample per symbol and does not need to be normalized. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-19transceiver: Fix mixed GSMK / 8-PSK transmissionTom Tsou1-1/+1
Input burst construction was declared static causing the first downlink burst from upstream to determine subsequent burst size and modulation. Consequently, fixed sequence EGPRS tests would pass, however, switching between 8-PSK and GMSK bursts would fail with only one modulation type being transmitted. Internally generated test sequences '-r' option were not affected because the bursts are not received through the socket interface. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-17uhd: Add command line option for GPS referenceTom Tsou5-13/+60
Unlike earlier versions of UHD, the current release (3.9.2) does not automatically select on-board GPSDO as the reference source. Modify the command line settings to allow explicit selection of GPS in addition to the external setting. Simultaneous GPS and external reference settingis disallowed.

2016-07-12UHD: Initial LimeSDR support.Alexander Chemeris1-1/+24
Only EDGE mode is currently supported. Traditional 1 SPS Rx / 4 SPS Tx mode requires different sampling rates which is not currently working. RF performance is also sub-optimal and requires more tuning.
2016-07-12radioInterface: Fix multi-channel buffer index bugTom Tsou1-1/+1
Discrete RF multi-channel was using hard coded buffer index on the channel iteration for transmit sample conversion. End result was segmentation fault on dual RF channel devices with both channels active (Ettus B210 and UmTRX). Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-08mcbts: Allow out of order channel setupTom Tsou2-6/+9
Previous checks on multi-channel TSC and ARFCN settings would fail if channels were initialized out of order. Namely, if channel 0 was not configured first, osmo-trx would error on the control interface leading osmo-bts to fail. Allow global TSC setting on all channels with added logging notice. Notify if channel frequency is unexpected - which may happen if channels are setup out of order - but do no report as error. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
