2018-12-12LMSDevice: make use of dev-args in osmo-trx.cfgOliver Smith1-2/+40
Allow selecting a specific LimeSDR device by setting dev-args in the config file. Split up the given dev-args address by comma and select the device where all substrings can be found. I could not test this with real hardware, but I have added a test case to make sure this works as expected. Related: OS#3654 Change-Id: Ib9aaa066a01bf9de3f78234d7ada884d6f28c852
2018-12-07lms: Do {under,over}run checks even if LMS_RecvStream failsPau Espin Pedrol1-1/+1
Under failure, it could still be that stream status is updated, so let's father that in all cases. Change-Id: I4e2b8be06d2993db1bab233948a8ee774b8ac4ee

2018-12-04lms: Make sure LMS_Close is called when Device is torn downPau Espin Pedrol2-0/+11
This change fixes lots of memory leaks inside libLimeSuite as announced by ASan after exiting the osmo-trx process (throgh CTRL+C for instance). This way also we make sure libLimeSuite can communicate with the HW and close whatever subsystems were enabled during LMS_Open time. Change-Id: I56ffb87079e34aa2d0322fd2ca6429742f9f7640
2018-12-03lms: Destroy streams on device stopPau Espin Pedrol1-0/+4
They are recreated during start(). Actually, if they are not stopped here, during start() after stop(), LMS_SetupStream() will fail because it will detect the streams are already opened. Change-Id: I70d47c287aabdabc5dc1304a942d130aeb10bdc5

2018-11-29lms: Set Rx gain to midpoint, as comment suggests.Harald Welte1-1/+1
So far, the Rx gain was set to 34 dB, wile the comment stated it would be set to half-point, which is 73/2=36dB. Let's adjust the code to match the comment. Change-Id: Idc646def53b83faf4e6c011fb595fa436e223b32
2018-11-29lms: User correct scale factor for transmit samplesHarald Welte1-1/+8
Due to (I believe) a copy+paste mistake from the USRP1 code, we were using only a scale range of up to 9830 when transmitting samples, rather than the full 16 bit signed integer range up to 32767. As a result, we were loosing almost two bits (MSBs) of resolution as well as a lot of transmit power. This changes the scale factor to 0.707 (1/sqrt(2)). Please note that the much higher DAC output level means that the analog gain should be reduced. The theoretic range of up to 73dB should not be used, but Lime Microsystems suggest a value of 61..67 dB. This can be achieved by using a "osmotrx tx-attenuation" value of 6..12 inside the osmo-bts-trx configuration file.

The following warning was observed with GCC 4.8.5: make[4]: Entering directory `.../osmo-trx/Transceiver52M/device/lms' CXX LMSDevice.lo LMSDevice.cpp: In member function 'LMSDevice::writeSamples()': LMSDevice.cpp:582:22: warning: 'rc' may be used uninitialized in this function [-Wmaybe-uninitialized] samplesWritten += rc; Let's fix this by zero-initializing 'rc'.

2018-09-03lms: Return error on device read timeoutPau Espin Pedrol1-3/+5
If LImeSDR device is unplugged or its fw crashes during operation, reading from the device will fail and will first receive short reads and finally 0 byte reads. Let's quickly notify these events to upper layers instead of trying to process the buffer and checking timestamps for something we know it's already not useful.

2018-08-17logging: Introduce new "DDEV" category for device-specific codeHarald Welte1-56/+56
The DMAIN category got too overloaded. Let's have the code in Transceive52M/device/* use the new DDEV category. Also, in some cases the log levels have been adjusted to ensure that enabling INFO level should not result in a complete overflow of messages during normal operation. Change-Id: I844fe4a75bf277cd3cc5bd8fa06e06ad97b2ea95
2018-06-20lms: Allow values diff than 34dB to be set by setRxGain()Pau Espin Pedrol1-3/+1
Until now, setRxGain in LMSDevice did not take into account the setter parameter and was always using hardcoded 34dB, which was experimentally found to be a good default value. Let's force that value during initialization, but still allow the upper layers (controlled by BTS) to set different values. osmo-bts only sends a SETRXGAIN command (which calls setRxGain in osmo-trx) if a value is explicitly set in its VTY config, so we are on the safe side if the user doesn't explicitly configure a desired dB.

2018-06-14lms: Fail in case of unsupported configurationHarald Welte1-0/+8
There might be some configuration that's not supported by osmo-bts-lms, and we should reject that properly. Change-Id: I6f82edce589030a4407f6150fb7e8abe6417c1f2 Closes: OS#3347

In Change-Id Ib2fca81b76d027b08e2891056fa076d071597783 we introduced some coding style violations. Let's make newly-added code follows standard Osmocom coding style. Change-Id: Ib7ddd275014f03a2eed3cddc02b1356e2b00c0bc
2018-06-14radioDevice: better encapsulation in base classHarald Welte2-10/+6
It's not good style to have the derived classes initialize members inherited from the base class using "this->foo = bar". Rather, let's make the base class have a constructor, and call that constructor to initialize the members of the base class. While doing this * rename 'offset' to 'lo_offset' to avoid confusion with timestamp offset * move 'InterfaceType' into the base class * move 'chans' into the base class * move 'rx_sps' into the base class * mark base class members as 'protected' Change-Id: Ib885675a7612a392aa7f75fca81269ddcff2f6ab

2018-06-13lms: Fix support for rx_paths / tx_pathsHarald Welte2-3/+10
Before this patch, any configuration in osmo-trx.cfg regarding the rx and tx "antenna" (path) would have been completely ignored, as the radioDevice::make() function would simply drop those arguments to the floor. Change-Id: Ie50f854abbc9dcf351cddc052d10206382e1d5d3

2018-06-13lms: Reduce Rx gain from 47 to 34 dBZydrunas Tamosevicius1-1/+1
Initially, Rx gain was hardcoded to be 47. This was too high for our setup and we were constantly getting "clipping detected" messages. Reducing Rx gain to 34 solved the issue. However, it looks like gains should be controlled through configuration files. Change-Id: I30580f18c4ad630c09f725b1d24c125fc3119809
2018-06-13lms: fix LMS_StartStream() handling for multiple channelsZydrunas Tamosevicius1-0/+5
LMS_StartStream() (in LMSDevice::start()) was moved to separate loop. It is because LMS_SetupStream() would fail for second channel if streaming has already been started (LMS_StartStream()) for single channel configuration. Change-Id: I6704bb92864aa81417507c4ae24a22f41dc529c1

2018-06-13LMSDevice: Fix initial timestamp offset of 2500Harald Welte1-1/+1
