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:

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.

Also take the chance to make sure we handle properly short reads (keep

Both scenarios can be tested by running osmo-trx-lms and then using

Since in next commit osmo-trx-lms starts using smpl_buf.cpp, it seems

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/

Original issue: In order to use SSE instructions, 16-byte aligned memory
chunks are needed, and C++ version < C++11 doesn't provide for a native
new/delete store. For that reason, memalign() must be used in the
implementation of convolve_h_alloc() for some buffers.
On the other side, The C++ code relies on C++ "new T[]" operator to
allocate a chunk of memory containing an array of class instances. As
classes are complex types, they cannot be allocated through C structures
(calling malloc). Experimentally can be seen too that it's unreliable
and the process will crash during startup if malloc() is used and then a
Complex<> deferred from it.
Previous implementation allowed for use of convolve_h_alloc or new[]
based on how the (signal)Vector is called, because then the buffer is
not going to be managed internally. But that's unreliable since resize()
calling resize() on it could use "delete" operator on a malloc'ed
buffer, and end up having a new new[] allocated buffer. It was also
found that some of the callers were actually leaking memory through ASan (because the
buffer is not managed by the Vector instance).
IMHO best option would be to rewrite all this code using C structures
and malloc/free exclusively, since it would make all this cod eeasier to
maintain.
But for now, let's extend the Vector class to allow specifying an
external alloc/free function and let the Vector instance take care of
the ownership of the buffer in all scenarios.

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

Change-Id: Idc646def53b83faf4e6c011fb595fa436e223b32
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.

When using multi-arfcn feature, several logical channels (arfcn) are multiplxed
into one physical transceiver, as can be seen in
uhd_device::set_channels.
As a result, when multi-arfcn is enabled some properties are actually
shared for those logical channels, and internally mapped to the first
(only existing) channel, and per-channel internal array variables are allocated
accordingly (size() == 1).
When setting RxGain, we need to set the correct existing physical
channel. Same check is done in getRxGain, and then we apply the RxGain correctly and
we avoid outputing an error "Requested non-existent channel" immediatelly after.

Transceiver::stop() can only be called from either CTRL iface thread or
from main thread (running osmocom loop). That's because stop attempts to
cancel and then join all the other threads, which would then lock if
attempting to stop from some of them.
As a result, the best option is to indicate to the user of the
transceiver option (osmo-trx.cpp) to stop it in a correct fashion by
destroying the object from the main thread.

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.

Also, in some cases the log levels have been adjusted to ensure

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.

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'

Before this patch, any configuration in osmo-trx.cfg regarding the rx

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.

Same way as we do in osmo-bts. After this commit, osmo-trx no longer
exists. Instead, osmo-trx-uhd and osmo-trx-usrp1 are generated based on
configure flags enabled.
A new flag --with(out)-uhd has been added to enable/disable build of
osmo-trx with UHD backend. It is left enabled by default to keep
compatibility with older build scripts. Binary with USRP1 backend must
still be manually enabled with --with-usrp1 flag.

There was no a simple range check for both (NO)HANDOVER commands,

familar with simple pointer arithmetics, so excessive amount of
memory and useless memcopying was used to parse a single command.

Parameter -l to set the terminal logging levle was removed in
3da1f8352e, but afterwards it was decided
to keep the cmd line options for a bit more to easy migration to VTY
cfg.
The command line no longer accepts keywords ("DEBUG", "INFO", etc.) but
log level numbers, due to libosmocore APIs log_parse_level and
log_level_str being marked as deprecated and for internal use only.
Keep in mind the log level is overridden by VTY cfg if any line sets log
levels for log stderr in there.
Explicit cast to unsigned int for loglvel is issued to avoid iostream
printing it as a char.

Existing cmd line options are kept for a while to give people some time
to move to use VTY cfg. All new cfg options should be set only through
VTY. VTY options take preference (override) over cmd line options.
Deprecated options are removed from help message to dissuade users from
keep using them.
Steps to drop cmd line options in the future:
- Drop comma_delimited_to_vector, print_deprecated
- Drop all options in handle_options marked with print_deprecated.
- Set "-c" param to do the same as "-C", to keep compatibility with old
param and still use same naming as all other osmocom projects.
- Remove the hack in main() to set 1 channel implicitly by default.

At this stage, osmo-trx still uses the cmdline parameters top run the

later used to drive the device. Device config can be printed in the VTY
with "show trx".

Some devices have different Rx or Tx ports with different RF characteristics.
For instance LimeSDR has H (High), L (Low) and W (Wide) band Rx ports,
each of one being more suitable to a specific range of frequencies.
In case one wants to support several GSM bands, the best option is to
use the WideBand port and connect the antenna physically to that port in
the board. Then the firmware must be instructed ro read from that port.
Support for Rx/Tx port configuration is already in there for all the
layers (Limesuite, SoapySDR, SoapyUHD, UHD), but we are missing the
required bits in osmo-trx to make use of the available UHD API. This
commit addresses it.
Before this patch, the Rx/Tx paths configured could be changed by means
of the LimeSuiteGUI app, but after running osmo-trx, the values were
changed to the default ones.
One can now start using osmo-trx with 1 channel and specific Rx/Tx ports
by using for instance: osmo-trx -c 1 -y BAND1 -z LNAW
Default behaviour if no specific path or an empry path is passed ("") is
to do the same as preiously, ie. nothing by not calling the
set{T,R}xAntenna APIs.
One can also configure only specific channels, for instance to configure
only the first Tx channel and the second Rx channel:
osmo-trx -c 2 -y BAND1, -z ,LNAW

Stop calling writeClockInterface() when receiving commands in Transceiver::driveControl,
otherwise it fools osmo-bts-trx clock skew check because it is always sending a clock
indication with the same fn when it issues any commands during the time in between
CMD POWEROFF and RSP POWERON, because fn is not increased during that period.
Also use mForceClockInterface flag to delay delivery of first IND CLOCK until we start
serving frames, otherwise the first one is sent and only after a long period of time
the next clock indications are sent, when the radio starts to process bursts. That makes
osmo-bts-trx unhappy because it expects to receive an IND CLOCK aprox at least every
400 frames. This way also we send the first IND CLOCK after the RSP POWERON 0 response.
