pdschRxdataF_comp data source was handled incorrectly. Each symbol entire slot data was copied. This
caused pdschRxdataF_comp to mostly contain zeros. The call to UEscopeCopy was moved from symbol loop
into last symbol processing. In case imscope is used padding and unused REs are not copied to the
sink.
Added checks inside scope functions to ensure correct functionality.
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
This fixes out-of-bounds access: nr_ulsch_16qam_llr, nr_ulsch_64qam_llr and nr_ulsch_256qam_llr.
For 256qam this also fixes incorrect llr calculation on arm: the existing AVX code for 2 REs
case produced results not in line with the rest of the code. A testcase check_2_res_256_qam was
added to visualise the differences which can later be used to revive AVX acceleration for 2REs case.
