2020-06-25Drop old TxGain APIs from parent radioDevice abstract classPau Espin Pedrol1-4/+0
All radioDevice subclasses except USRPDevice have already been reworked to use the new SetPowerAttenuation() methods, hence we can drop the compatibility layer that was added to transition from the old API to the new one, and move those functions to USRPDevice. This way we simplify the parent abstract class with methods not needed by most devices and not used anymore by external users of those classes. Change-Id: Ice005cd0a07c49b6e212c06f1228ef93c24db727
2020-06-25LMSDevice: Compute TxGain on LimeSuite API based on expected Tx output powerPau Espin Pedrol2-51/+144
Right now, according to a few measurements taken on LimeMicro devices, we expect the Tx Gain at UHD level to relate 1:1 with the slope in Tx output power given a specific band. If more fine-grained results are wanted or some device doesn't follow a 1:1 slope relationship, functions TxGain2TxPower and TxPower2TxGain need to be adapted/improved. This patch is basically doing the same thing as was done previously for UHDDevice in 992c9bd1cea410e2dd42ce7566299104b5648aff. Related: OS#4583 Change-Id: If154fe4d4cd118aa30ea43c22ee7119117b77da6
2020-06-09radioInterface: Operate on real Tx power attenuation rather than on device ↵Pau Espin Pedrol1-14/+13
specific gains All the Tx gain related APIs are left out of reach from radioInterface, and in there we simply interact with radioDevice passing the attenuation received from TRXC. Prior gain logic is moved in base radiodevice class, with the idea that the setTxGain() and related functions will be dropped over time in each sublcass in favour of an specific implementation of the SetPowerAttenuation API.

2020-06-08Transceiver: Implement TRXC cmd NOMTXPOWERPau Espin Pedrol2-0/+10

2020-03-12radioDevice: Drop unused isControl param from WriteSamples APIPau Espin Pedrol2-10/+2
The out "isControl" parameter is only used by internal callers of USRPDevice, and not used at all by any user of the generic API (radioInterface*.cpp). Hence, we can get rid of it and keep it as a flag for an internal API of USRPDevice. Change-Id: I843384e24b76cdd28a95f9ee4e95e6157098e4a3
2020-03-12radioDevice: Drop unused RSSI param from readSamples APIPau Espin Pedrol2-3/+2
The out "RSSI" parameter is only filled by USRPDevice, and not used at all by any user of the API (radioInterface*.cpp). RSSI seems to be computed nowadays in the common path in Transceiver::pullRadioVector(). Change-Id: I06c2ea5a9891d170bc468f952bbf2a7e64d95784
2020-01-15lms: Initial multi-arfcn supportPau Espin Pedrol1-7/+17
With current state multi-arfcn can be used (eg. I can place a call between 2 phones using TRX1 and sustain for as long as wanted), but from time to time (around every 20seconds), a burst of Tx packed dropped events from LimeSuite appears. LimeNet-micro coefficients have yet not been tested. Related: OS#4362 Change-Id: I7e67d90a8126546eeeeba376f816ec5d158d4712

2020-01-15lms: Store device type specific parameters in one placePau Espin Pedrol2-25/+117
Add an enum containing each supported device type (LimeSDR-USB, LimeSDR-Mini and LimeNet-Micro) plus "unknown", to leave some room for yet-to-come devices to run with some generic parameters without rebuilding osmo-trx. Each device type is assigned a dev_desc structure, and all of them are put in HashMap, similar to what's already done in UHDDevice.cpp. Device type is infered from string provided by LMS_GetDeviceInfo(), as it was already done before in several places. From now on, we only need to parse the string once since we store the device type after first during open time. Later on, more fields will be moved to device-type specific structure, such as Tx timing offset, clock rate, etc. Change-Id: I7658615787c5bc41c365bab9c11733b701ac2ae5
2020-01-15lms: Move rx_buffers allocation to constructorPau Espin Pedrol1-4/+5

2020-01-13lms: Change radioDevice constructor arg name to avoid masking instance attrPau Espin Pedrol2-3/+3
channel number mangling based on multi-arfcn feature being enabled was moved to generic radioDevice() to reuse code. Hence, the generic parent constructor sets this->chans to 1 if multi-arfcn feature is requested. However, LMSDevice constructor argument had same name as the class instance attribute, taking preference. As a result, if multi-arfcn is enabled in LMSDevice, the generic constructor first sets this->chans=1 but afterwards LMSDEvice constructor keeps calling .resize() with the argument value "chans" instead of using this->chans. Let's rename the argument in all radioDevice child class constructors to avoid potential future bugs in all of them. Change-Id: Id6c837e9133f22783dd92a81dfcc493e51bf2d21

2019-08-21Drop old setPriority related codePau Espin Pedrol1-4/+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.

2019-08-01lms: 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.

It was initially thought that underruns/overrun fields were increasing-over-time values. However, after reading LimeSuite code, it seems overrun and underrun fields are actually reset upon every call to LMS_GetStreamStatus().

2019-06-05Add rate_ctr support to store/retrieve SDR errors through VTYPau Espin Pedrol2-36/+45
Introduce a unified implementation-agnostic interface for radioDevice to signal SDR error counters to upper layers and manage them. This patch only implements counters for osmo-trx-lms (other devices will show all counters unchanged during time). Sample use through VTY: """ OsmoTRX> show rate-counters osmo-trx statistics 0: device:rx_underruns: 0 (0/s 0/m 0/h 0/d) Number of Rx underruns device:rx_overruns: 0 (0/s 0/m 0/h 0/d) Number of Rx overruns device:tx_underruns: 0 (0/s 0/m 0/h 0/d) Number of Tx underruns device:rx_drop_events: 4 (0/s 2/m 3/h 0/d) Number of times Rx samples were dropped by HW device:rx_drop_samples: 513 (0/s 196/m 425/h 0/d) Number of Rx samples dropped by HW """ Change-Id: I78b158141697e5714d04db8b9ccc96f31f34f439
2019-05-24lms: Fix stream_stats checks with droppedPacketsPau Espin Pedrol1-3/+5
Existing code had a typo (value was assigned from wrong variable). Furthermore, it was experimentally found that: while underrun/overrun are documented as "FIFO overrun count" in LimeSuite.h, it seems droppedPackets ("Number of dropped packets by HW") is not actually an incrementing counter like the others, but simply a value set every time LMS_RecvStream() is called. Since we are actually interested in keeping the count over time, adjust code to achieve that. Change-Id: Id93d33400e11360b9536f56a31904328549cfbbf

2019-05-06smpl_buf: Move it to device/common and create libdevice_common.laPau Espin Pedrol1-1/+1
Since in next commit osmo-trx-lms starts using smpl_buf.cpp, it seems some automake step doesn't like including a cpp file twice from a different directory, since race conditions can occur building it. Instead we define the dependency by first building a static lib and then using it on each libdevice.la (one per device type). We already do the similar under arch/ subdir, where we have a common/ subdir and then one subdir and lib per architecture. Change-Id: I465ad0f6d5569bb3006d711c8fd0df14391fcf35
