2017-12-14initial libxtrx supportSergey.Kostanbaev1-0/+4
2017-08-16Add -j option to bind to specific addressPau Espin Pedrol1-8/+16
Before this patch, the binding of the listening sockets was hardcoded to a local IP. Change-Id: I9ba184a1251c823e413a9230943ed263e52142ec
2017-07-20Add '-t' command line option to enable SCHED_RRHarald Welte1-2/+29
SCHED_RR allows us to operate osmo-trx reliable even under exceptionally high system load, as the realtime scheduler priority will have higher priority than the other "regular" tasks on the system. Change-Id: Ia2452b9763960b2be37fbeee9d832554da68a53f Closes: OS#2344
2017-06-08ssedetect: call __builtin_cpu_supports() only if supportedVadim Yanitskiy1-0/+8
Some compilers don't support the __builtin_cpu_supports built-in, so let's make them able to compile the project anyway. Change-Id: I0c90402d8e4c9f196c54b066ff30891c8de3ad2b
2017-05-19radioInterface: Remove UmTRX 'diversity' optionTom Tsou1-32/+0
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. Change-Id: I46752ccf5dbcffbec806081dec03e69a0fbdcdb7
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
2017-05-19ssedetect: Add runtime CPU detectionPhilipp Maier1-0/+8
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
2017-04-10config: 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
2017-04-03Transceiver: Remove unsigned negative comparesTom Tsou1-1/+1
Change-Id: I49f30699786c52736ef334dae61f7bbd65d878d5 Fixes: Coverity CID 149353, 149356
2016-07-20uhd: Update USRP2/N200/N210 for 4 SPS RxTom Tsou1-23/+35
Requires changing the radioInterface API to pass in Rx side SPS value. Update the (deprecated) diversity configuration to match as well. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-17uhd: Add command line option for GPS referenceTom Tsou1-6/+31
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. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-01egprs: Enable 8-PSK burst detection when EDGE is enabledTom Tsou1-2/+2
The command line EDGE option will enable 8-PSK burst detection on any slot where a normal burst is expected. The burst search order is 8-PSK first followed by GMSK. EDGE will force 4 SPS sampling on Tx and Rx. Along with twice the search correlation from 8-PSK and GMSK, EDGE will increase CPU utilization. Whether the increase is notable or not is dependent on the particular machine. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-01mcbts: Add multi-ARFCN radio supportTom Tsou1-7/+38
Add new radio interface "radioInterfaceMulti" for multi-carrier support. Only USRP B200/B210 devices are supported because of sample rate requirements (3.2 Msps). Only 4 SPS operation Tx/RX is supported. 8-PSK is supported. Other options may be added at a later time Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-01radioInterface: Convert diversity argument to general typeTom Tsou1-2/+3
Rather than a simple bool type, convert the diversity switch to the device interface specifer: enum InterfaceType { NORMAL, RESAMP_64M, RESAMP_100M, DIVERSITY, }; The more general specifier allows passing in special cases other then selection diversity such as multi-ARFCN support. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-01transceiver: Add Rx samples-per-symbol optionTom Tsou1-12/+12
Previous approach was to enable 4 SPS on the receive path only for EDGE use, which is not a requirement for 4 SPS operation. Make the 4 SPS configuration setting directly settable. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-06-22transceiver: Add an option to emulate a RACH delay in random filler mode.Alexander Chemeris1-4/+13
Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-05-03uhd: Set default Tx sampling to 4 spsTom Tsou1-6/+1
The majority of GSM host platforms are capable of operating with the 4x oversampled modulator, which justifies the new default setting. The small number exceptions (e.g. Raspberry Pi) can still use the lower complexity 1 sps modulator with the '-s 1' command line option if required. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-04-26osmo-trx: Output Rx SPS as a part of configuration output.Alexander Chemeris1-0/+1
2016-04-20transceiver: Add an option to generate random Access Bursts.Alexander Chemeris1-1/+8
2016-03-08EDGE: Add random burst generator filler optionTom Tsou1-2/+8
When EDGE is enabled with the '-e' option, the random burst generator switches from GMSK normal bursts to 8-PSK EDGE bursts. $ ./osmo-trx -e -r 7 Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-03-08EDGE: Add interfaces to enable EDGE transceiverTom Tsou1-2/+21
Create EDGE slot type in the Transceiver. When EDGE mode is enabled for a particular slot, blind detection will be performed by correlating against EDGE followed by normal bursts if no EDGE burst is found. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-03-06EDGE: Setup variable sampling on receive pathTom Tsou1-16/+28
Allow setting the device to non single SPS sample rates - mainly running at 4 SPS as the signal processing library does not support other rates. Wider bandwith support is required on the receive path to avoid 8-PSK bandlimiting distortion for EDGE. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2015-07-30osmo-trx: Add an option to swap channels on UmTRX.Alexander Chemeris1-3/+10

2015-05-24osmo-trx: Fix random filler command line option.Alexander Chemeris1-2/+12
Filler types was of "bool" type, which prevented it from taking values greter than 1. And RAND filler type has integer value of 2, which was casted to 1 on assigning, which led to a normal filler table being used instead of the RAND one.
2015-05-19test: Add command line random normal burst optionTom Tsou1-18/+26
2014-12-15Transceiver52M: Implement POWEROFF commandTom Tsou1-2/+0
Add stop and restart capability through the POWEROFF and POWERON commands. Calling stop causes receive streaming to cease, and I/O threads to shutdown leaving only the control handling thread running. Upon receiving a POWERON command, I/O threads and device streaming are restarted. Proper shutdown of the transceiver is now initiated by the destructor, which calls the stop command internally to wind down and deallocate threads. Signed-off-by: Tom Tsou <tom@tsou.cc>
2014-03-06Transceivert52M: Add option for baseband frequency offsetThomas Tsou1-3/+11
Allow command line setting of the DSP frequency in UHD. All channels will be tuned with the same offset. Dual-channel tuning with the B210, which uses a single LO, will override the command line offset value and set the DSP frequency automatically. Signed-off-by: Thomas Tsou <tom@tsou.cc>
2014-01-26Transceiver52M: Disable filler table retransmissions by defaultThomas Tsou1-4/+12
Burst selection at a particular time works in the following order of priority. 1. Slot is disabled with channel combination set to NONE (default) 1. Burst exists in priority queue for the current time. 2. Filler table entry is used This patch sets default behaviour to force all filler table entries to zero and disallows filler table changes. This effectively means that only bursts received from upper layers will be transmitted and nothing will be automatically transmitted in the absence or delay of incoming burts at a particular time. New Command line option "Enable C0 filler table" allows reverting to previous idle burst generation and retransmission behaviour on TRX0. Retransmission cannot be enabled on non-C0 channels.

2013-11-17Transceiver52M: Remove database configuration file requirementThomas Tsou1-31/+14
We don't require any parameters stored in the configuration table, so don't bother with the existence of the persistent database file. This also removes an unnecessary step during initial setup since relevant parameters can be configured from the command line. Signed-off-by: Thomas Tsou <tom@tsou.cc>
2013-11-16Transceiver52M: Create new osmo-trx executableThomas Tsou1-0/+412
Create new main executable with full command line option parsing of relevant parameters. Database configuration table still exists (and must exist because of the global gConfig object), but can be bypassed with command line options. Signed-off-by: Thomas Tsou <tom@tsou.cc>
