Experiments did show that the time sync is less stable in terrestrial mode if the integral part of the PI controller is used.
So set it to 0.0 by default. For NTN LEO use case we can still use it by providing the command line parameter --time-sync-I 0.2 .
fixes#846
xran has a mechanism to request DPDK to allocate a configurable amount
of bytes for huge pages. We set it to 0 until now; expose this variable
through configuration, and provide a meaningful default 8192 MiB.
Provide documentation.
A new phy scope based on ImGui and ImPlot. This scope uses a different concurrency model than previous
scopes.
The PHY thread writing the data first checks if the data is ready to be written. If its not, nothing is copied.
The GUI thread reads data if available and marks it ready to write. This makes sure that the PHY threads are not
busy copying data that would never be displayed.
Some of the scopes also have a freeze functionality that further limit the amount of data that needs to be copied
from PHY threads. If a scope is "frozen" it still allows the user to explore the data using plots zoom/pan functions
but doesn't cause PHY threads to perform extra writes on the displayed data.
A compile option was added to enable/disable the scope. Use cmake -DENABLE_IMSCOPE=ON to enable the scope.
Update CXX standard to 17; it is required by some libraries (e.g., dear imgui). The oldest gcc version in
use by a distribution supported is Ubuntu 20, which has gcc 9.4 with c++17 support.

Before this commit, the following will trigger a complete rebuild:
- create another git name (git checkout -b test)
- run cmake again manually (cmake ..)
- run ninja again
The top-level CMakeLists.txt uses add_definitions() to add git
information to all targets; if some git information changes, this will
mark all command lines as dirty, triggering the build.
There is an easy solution: instead of passing this information on the
command line, pass it in a header. This commit uses configure_file() to
generate a file oai_version.h in the build directory with the same
information. Various sources files, e.g., main executables, use this to
output the same information as before. It is then also not necessary to
use header guards, as cmake takes care to create this file.
If cmake is re-run, it will update the header, and trigger only files
including this header will be rebuilt (which can be shown with the above
stpes). The information passed is the same as before, and updates the
information when the old method would have updated it.
This commit introduces google benchmark library and one benchmark for
rotate_cpx_vector. Also extracted common tools used in testcases for
generation and allocation of byte aligned vectors in phy_test_tools.hpp
The correct order for xran seems to be first Uplane, then C plane. In
the past, we used to switch (for reasons I don't know), but let's
reverse it to the proper order.
* place all NR UE CL optional options in the same section, in a table
* add a section for common CL options
* add subsection for UE capabilities
* removed redundant text
* In LTE there is logic that checks the thread configurtion with the
getters `get_thread_parallel_conf()` and `get_thread_worker_conf()`
in NR these getters are not used, only setters, which have no impact
- Enabled configuration for number of dl, ul harq processes in conf file
- set "num_dlharq = 32; num_ulharq = 32;" under "gNBs" section in the conf file
- default values when not configured is 16 for DL, UL harq processes
- IEs in the RRC messages set according to the number of DL, UL harq processes configured.
- If value 32 is configured , then IEs related to num harq processes and dci bits also configured in Bandwidth parts.
I don't know about any user of the kernel modules. It is effectively
legacy code we carry around, for no good reason. Remove it for the
moment. If we ever need it, we can revert.
