There was concern that someone in the future might call the function with the wrong inputs. So, based on the discussion on the MR below https://gitlab.eurecom.fr/oai/openairinterface5g/-/merge_requests/2916#note_132506 the SIMD for multiplying DMRS vector with amplitude is removed and is now done with plain C (no SIMD). The execution time for the function dmrs_amp_mult() in this commit is 10x higher that the previous commit.
xForms-based Scope
How to run and troubleshooting
To compile OAI, build with scope support:
./build_oai --build-lib nrscope ...
To use the scope, run the xNB or the UE with option -d. If you receive the
error
In fl_initialize() [flresource.c:995]: 5G-gNB-scope: Can't open display :0
In fl_bgn_form() [forms.c:347]: Missing or failed call of fl_initialize()
you can allow root to open X windows:
xhost +si:localuser:root
Usage in gdb with Scope enabled
In gdb, when you break, you can refresh immediately the scope view by calling the display function. The first parameter is the graph context, nevertheless we keep the last value for a dirty call in gdb (so you can use '0')
Example with no variable known
phy_scope_nrUE(0, PHY_vars_UE_g[0][0], 0, 0, 0)
or
phy_scope_gNB(0, phy_vars_gnb, phy_vars_ru, UE_id)
