The failure mode observed here was that the CU sent a release command
for a UE that the DU does not know. Given, that the outcome of the
release command (no UE) is equal to the current state (no UE), from
the DU point of view, we can safely ack the command.
This is a temporary workaround for issue with UE PHY not applying TX power
instructions from MAC. To be reverted once implementation of TX gain control
is finished.
This commit adds yaml-cpp library to required docker images and build commands. There is one workaround
in cross-compilation for apt behavior for installing libyaml-cpp-dev. Apt will uninistall previous
versions of the package whenever another one is installed. This means that installing the arm version
breaks amd version and vice versa. This makes it impossible to have both libs installed at the same
time which is required by the cross-compilation build command (it calls cmake twice, once with native
and once with target architecture)
This commit introduces a substitute module library for setting up softmodems using YAML instead of libconfig.
The softmodems should work the same with both types of files. Extra care was put to make sure the behavior
of both modules is the same.
Example yaml config files were added for the UE and gNB
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.
Create_Workspace is used used in XML files instead of directly being
executed in DeployObject(). This can be problematic if we deploy
multiple services on the same host, since a previous workspace will be
deleted. Also, it removes futile git clones.
There are other XML steps (CppCheckAnalysis, LicenceAndFormattingCheck,
BuildImage, BuildProxy, BuildClusterImage) that implicitly called
Create_Workspace. Those calls have been removed and care has been taken
to insert the corresponding Create_Workspace steps in the XML.
