Clayton Smith 159885f9e6 Replace boost::shared_ptr with std::shared_ptr 
Signed-off-by: Eric Wild <ewild@sysmocom.de>
 2021-01-18 21:15:57 +01:00
Clayton Smith 52fcb0935f A lot of Boost functionality is available in C++11. Since GNU Radio is moving away from Boost, it probably makes sense to do so in gr-osmosdr as well. 
This change removes all usage of boost::mutex,
boost::mutex::scoped_lock, boost::unique_lock, and
boost::condition_variable. It also removes usage of boost::shared_ptr
and boost::weak_ptr outside of block definitions (which must continue to
use Boost until GNU Radio 3.9).

Krzysztof Halasa 33a8d1c2ae RTL-SDR: convert _lut to float[] to reduce size by a factor of 256 
The _lut is being indexed by I + Q (16 bits = 65536 entries), however
both samples can be processed independently, resulting in 8-bit LUT.
Saves a bit of RAM and CPU cache.

Dimitri Stolnikov 7e55cb9224 introduce osmosdr namespace, remove _c suffix 
- the namespace conversion adopts the common gnuradio coding guidelines
- suffix removal is a preparation to support 8/16 bit complex data types

Dimitri Stolnikov 86ec5d3b73 add if gain setter API for rtl-sdr 
and OsmoSDR devices

Observations lead to an useful gain
range from 15 to 30dB, a value of
24dB is used by default.
