Some people needed that.
Let's stop to 19 for the time being. It's tricky enough.
We can increase later if needed. (A previous commit
made the tracers to accept up to 32 variables.)
T_MAX_ARGS was 16 and some people start to use the T machinery with
more than 16 values. So be it. Let tracers be friendly and accept 32.
(More commits to follow for full support.)
Also why is T_MAX_ARGS in T_defs.h when it's only used by event.h?
Hum?
Pass consistently the NR_timer_t object through a pointer. Since we have
to modify all occurrences of is_nr_timer_active(), we use that occasion
and rename that function to nr_timer_is_active() to make it consistent
with all other functions, starting with nr_timer.
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
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.
- MAX HARQ PROCESSES set to 32
- for PDSCH - default setting in OAI is 16, according to 3GPP rel17 38.331 these are the possible configs
- if no IES are defined then 8
- if nrofHARQ-ProcessesForPDSCH is defined then these values- {n2, n4, n6, n10, n12, n16}
- if nrofHARQ-ProcessesForPDSCH-v1700 is defined then 32
- for harq bits in DCI
- DCI 1_0 - 4 bits spec 38.212, section 7.3.1.2.1
- DCI 1_1 - 4/5 bits according to IE harq-ProcessNumberSizeDCI-1-1, spec 38.212, section 7.3.1.2.2
- for PUSCH - default setting in OAI is 16, according to 3GPP rel17 38.331 these are possible configs
- if no IES are defined then 16
- if nrofHARQ-ProcessesForPUSCH-v1700 is defined then 32
- for harq bits in DCI
- DCI 0_0 - 4 bits spec 38.212, section 7.3.1.1.1
- DCI 0_1 - 4/5 bits according to IE harq-ProcessNumberSizeDCI-0-1, spec 38.212, section 7.3.1.1.2
- FOR HARQ32 , DCI 1_1, DCI 0_1 should be configured in UE dedicated search space. In OAI it is set.
This assert and assumption is incorrect, according to 38.101-1 UE channel is defined only by the BWP size
and BWP size can be any value supported by the RRC parameters defining the BWP.
To determine the UE channel the smallest bandwidth supporting the BWP is selected. This is an assumption based
on references in the same document to UE channel bandwidth being equal to one of the values in set
{5, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70, 80, 90, 100}.
Also:
- calculated P_CMIN during BWP setup since the parameter doesn't depend on DCI.
- initiialize uniqCfg structure in test_nr_ue_power_procedures main function which enables LOG prints during tests
