* rtlsdr_set_tuner_sideband(): - "HF-Hase" Bernhard Kistinger (DB9PP) found out, that one of the undocumented I2C register bits of R820T tuner controls the used tuner/mixer lower or supper sideband. That was by testing/playing with a special QIRX version, showing and allowing change of all I2C registers. - previous additions in rtl_tcp allowed control of I2C registers; in addition register contents can be transmitted periodically (to QIRX) - "Oldenburger" developed a first version controlling the sideband bit, and additional spectral flipping (spectrum inversion) in the RTL2832 - i've merged Oldenburger's changes with my rtlsdr_set_tuner_band_center() => altogether, there's no spectrum inversion, the band center stays, just the IF filters (steep lowpass and not-so-steep highpass) switch positions * Oldenburger's changes for FC0012 tuner * Oldenburger added description of R820T's I2C registers * rtl_tcp's new response channel now occupies an additional port, usally 1235, which is +1 of default control port. this can be deactivated by command line Signed-off-by: hayati ayguen <[email protected]>

librtlsdr uses two fileds of struct rtlsdr_dev to communicate between threads. On hardware with weak memory model it is not guaranteed that it will work, as C memory model guarantees nothing for simple variables. Using C11 atomics seems to be overkill here, but async_status and async_cancel better be marked as "volatile".

Recently merged PR left this unaddressed.

If the librtlsdr code comes from a tarball, it doesn't have any .git/ metadata, and therefore even if Git (as a tool) is found, the logic in cmake/Modules/Version.cmake fails finding a version through Git: -- Extracting version information from git describe... fatal: Not a git repository (or any of the parent directories): .git As a consequence, the VERSION variable is empty, which later causes cmake to bail out with: CMake Error at /home/test/autobuild/run/instance-1/output-1/host/share/cmake-3.15/Modules/WriteBasicConfigVersionFile.cmake:43 (message): No VERSION specified for WRITE_BASIC_CONFIG_VERSION_FILE() Call Stack (most recent call first): /home/test/autobuild/run/instance-1/output-1/host/share/cmake-3.15/Modules/CMakePackageConfigHelpers.cmake:225 (write_basic_config_version_file) CMakeLists.txt:173 (write_basic_package_version_file) To avoid this, we only use Git to determine the version if the cmake project top-level source directory has a .git/ folder.

Gets rid of librt, which doesn't exist on OpenBSD. The version of librtlsdr in the OpenBSD ports tree is extremely old (~2013), so this should help some users. Tested against tag 0.6.0, but it should apply just fine to HEAD.

cmake 3.19 warns about dropped compatibility for cmake less than 2.8.12 in the future. This patch updates the minimum required version to 2.8.12 to avoid the warning. cmake 2.8.12 was released in 2013 so it should be safe to update the minimum required version from 2.6 to 2.8.12 without loosing support for older os versions.

…dows builds

Change CMAKE_SOURCE_DIR to PROJECT_SOURCE_DIR to allow for inclusion of librtlsdr as a subdirectory in another cmake project. For a standalone build, PROJECT_SOURCE_DIR and CMAKE_SOURCE_DIR work pretty much the same, but if a projet is included into another with add_subdirectory PROJECT_SOURCE_DIR must be used.
