+ * rate_ctr API uses several osmocom select loop features, and as a result,
+ * calls to it must be done through the main thread (the one running the osmocom
+ * loop in osmo-trx).
+ * Since read/write from/to SDR is done in separate threads (even read and write
+ * each use a different thread), we must use some sort of message passing system
+ * between main thread feeding rate_ctr structures and the Rx/Tx threads
+ * generating the events.
+ * The idea is that upon read/write issues, lower layers (SDR APIs) provide us with
+ * underrun/overrun/droppedPackets information, and in that case we pass that up
+ * the stack through signal <SS_DEVICE,S_DEVICE_COUNTER_CHANGE> with signal_cb
+ * being a pointer to a "struct device_counters" structure, which contains
+ * device (implementation agnostic) statful counters for different kind of
+ * statistics.
+ * That signal is processed here in device_sig_cb, where a copy of the "struct
+ * device_counters" structure is held and the main thread is instructed through
+ * a timerfd to update rate_ctr APIs against this copy. All this is done inside
+ * a mutex to avoid different race conditions (between Rx andTx threads, and
+ * between Rx/Tx and main thread). For the same reason, callers of signal
+ * <SS_DEVICE,S_DEVICE_COUNTER_CHANGE> (device_sig_cb), that is Rx/Tx threads,
+ * must do so with PTHREAD_CANCEL_DISABLE, in order to avoid possible deadlocks
+ * in case the main thread decides to cancel other threads due to a shutdown
+ * operation (fi SIGKILL received)

+About OsmTRX
+============
+
+OsmoTRX is a software-defined radio transceiver that implements the Layer 1
+physical layer of a BTS comprising the following 3GPP specifications:
+
+* TS 05.01 "Physical layer on the radio path"
+* TS 05.02 "Multiplexing and Multiple Access on the Radio Path"
+* TS 05.04 "Modulation"
+* TS 05.10 "Radio subsystem synchronization"
+
+OsmoTRX is based on the transceiver code from the
+[OpenBTS](https://osmocom.org/projects/osmobts/wiki/OpenBTS) project, but setup
+to operate independently with the purpose of using with non-OpenBTS software and
+projects, while still maintaining backwards compatibility with OpenBTS when
+possible. Currently there are numerous features contained in OsmoTRX that extend
+the functionality of the OpenBTS transceiver. These features include enhanced
+support for various embedded platforms - notably ARM - and dual channel
+diversity support for the Fairwaves umtrx.

-The Transceiver
-
-The transceiver consists of three modules:
-   --- transceiver
-   --- radioInterface
-   --- USRPDevice
-
-The USRPDevice module is basically a driver that reads/writes
-packets to a USRP with two RFX900 daughterboards, board 
-A is the Tx chain and board B is the Rx chain.  
-
-The radioInterface module is basically an interface b/w the
-transceiver and the USRP.   It operates the basestation clock
-based upon the sample count of received USRP samples.  Packets 
-from the USRP are queued and segmented into GSM bursts that are
-passed up to the transceiver; bursts from the transceiver are
-passed down to the USRP. 
-
-The transceiver basically operates "layer 0" of the GSM stack,
-performing the modulation, detection, and demodulation of GSM 
-bursts.  It communicates with the GSM stack via three UDP sockets,
-one socket for data, one for control messages, and one socket to
-pass clocking information.  The transceiver contains a priority
-queue to sort to-be-transmitted bursts, and a filler table to fill
-in timeslots that do not have bursts in the priority queue.  The
-transceiver tries to stay ahead of the basestation clock, adapting 
-its latency when underruns are reported by the radioInterface/USRP.
-Received bursts (from the radioInterface) pass through a simple 
-energy detector, a RACH or midamble correlator, and a DFE-based demodulator.
-
-NOTE: There's a SWLOOPBACK #define statement, where the USRP is replaced
-with a memory buffer.  In this mode, data written to the USRP is actually stored 
-in a buffer, and read commands to the USRP simply pull data from this buffer.
-This was very useful in early testing, and still may be useful in testing basic
-Transceiver and radioInterface functionality.
