30 hoursvty: Simplify filler burst settings and improve help and readability.HEADmasterAlexander Chemeris1-3/+3
In the command line options time, filler table/filer burts settings were a bit difficult to undertand because the number of one-letter settings was limited. Now, with VTY configuration, there is no reason to keep it so difficult. Also, after the previous commit it was no longer posible to enable random 8-PSK filler bursts. With this patch you can configure all supported filler bursts in a simple and logical way. Change-Id: I752eb2c1162d084e8769181f2fcd6c0877663448

13 daysUse new libosmocore logging lock APIPau Espin Pedrol1-4/+1
Since libosmocore Id7711893b34263baacac6caf4d489467053131bb, a new API log_enable_multithread() is available which takes care of protecting logging infrastructure from us (and actually does it correctly since we cannot protect internal libosmocore structures from osmo-trx). Let's drop all mutex related code from osmo-trx logging infra and simply rely on libosmocore's. Related: OS#4088 Change-Id: I519d0f30bce871005ca26b90177ea4aa4839360a

2019-09-20radioInterface: Atomically fetch and change underrun variablePau Espin Pedrol5-10/+16
Otherwise, it could happen that underrun events are lost: TxLower (isUnderrun): RxLower (pullBuffer): read(underrun) read(underrun) write(underrun, |val) [maybe underrun becomes TRUE] write(underrun, false) Similary, it could happen the other direction if atomic was only applied to isUnderrun: TxLower (isUnderrun): RxLower (pullBuffer): read(underrun) -> true read(underrun)-> true write(underrun, false) write(underrun, true|val) where val=false So in here isUnderrun would return true twice while it should only return one.

2019-09-20Transceiver: Fixed copying of history into and from channelizer buffer.Timo Jacobus1-1/+1
In multi arfcn mode, osmo-trx would drop some bursts because it couldn't detect it and would emit idle burst instead. Specificaly detection of peak in correlation vector failed. Correcting copying of history in pullBuffer method fixes this issue.

2019-08-26Transceiver: exit process when BTS drops connectionPau Espin Pedrol2-30/+53
We don't want to keep osmo-trx running in a started state once the BTS controlling it becomes unavailable. If a socket towards the BTS fails, it means the BTS is gone and the best thing to do is to stop the process (alternatively we could go back to stopped state instead, and wait for BTS to re-connect, fur so far this action is good enough).

2019-08-21Drop old setPriority related codePau Espin Pedrol8-32/+0
This code is not needed anymore since we are setting SCHED_RR scheduler with a real time priority in main thread during startup, so all threads will inherit same rt priority, which should be enough to keep the process working reliably even on high system loads (from non rt processes). osmo-trx was tested to be reliable during test with stress-ng as explained in related ticket below.

2019-08-14osmo-trx: log to stderr on signal receivedPau Espin Pedrol1-2/+2
Since osmo-trx it's a big multithreaded process and shutdown sequence can be complex, better use stderr to log signal received events to make sure log is outputted straigh away and not buffered. In general stdout is usually line-buffered, but buffering strategy can be more conservative if output is for instance redirected to a file. Change-Id: I70ba86919d1f7df41ef3db4916317d27697a025c

Newer versions of libosmocore's osmocom/core/socket.h include that header so the define is present, but older versions of libosmocore (such as 0.12.0) don't, so let's include it explicitly (the correct thing to do).

2019-08-01lms: Drop rx_underruns rate ctr, add tx_drop_* rate ctrPau Espin Pedrol2-28/+61
After discussion in [1] and further look at the code, it became obvios rx_underrun events are not happening in general for any SDR (don't exist), so let's drop that counter. Instead, add Tx Dropped Packet counters, which were not accounted prior to this commit.

2019-07-29radioInterface: Clarify how underruns are handled driving a radioDevicePau Espin Pedrol1-1/+3
The underrun parameter in radioDevice's readSamples() is not a "Rx Underrun" event, but rather it's used to retrieve a "Tx Underrun" which on some SDRs (like USRP1) seems to be (so far) available only at readSamples() times. Thus, underrun parameter for both readSamples() and writeSamples() is actually flagging the same event, and should be ORed in pushBuffer() as it's already done in pullBuffer(). Otherwise if implementation is setting the underrun pointer to false, it could erase the flag being marked by the counterpart function before isUnderrun() is called (which is the one responsible to clear the flag).

2019-07-23Transceiver: Clean up code passing parameters to threadsPau Espin Pedrol2-45/+37
TransceiverChannel naming was misleading there.

Furthermore, we don't need a full C++ class for that, let's simply use a struct. Change-Id: I6e3898a8a66520cc5b2a7df9b9ae01b0b272387f
