This avoids the issue of compare_exchange_weak always failing. The issue
was that `store()` is not equal to `exchange()`. `exchange` uses memory
copy while `store()` copies the value representation of the argument, which
is not always the same thing.
- Added event parameter for recording which is reflected in the filename
- Added event in the UE for DLSCH NACK
- Added program name to the filename for ease of identification
- Reworked spinlock to use atomics
This commit introduces the following changes to ImScope:
- Added the ability to record IQ data using the same mechanism as ImScope.
- Added a new executable target `imscope_iq_file_viewer` for viewing IQ files.
- Introduced a command line argument `--imscope-record` that enables data recording mode.
- Refactored a lot of the scope code
Usage:
- To record IQ data, run a modem with `--imscope-record` flag.
The recording happens whenever a modem calls dumpScopeData, which currently is
done only in gNB on PUSCH DTX and PUSCH CRC NOK.
There is a limit of ~1GB of files written by the thread in a signle run to avoid
accidentally exhausting disk space.
If a directory `imscope-dump` is available the data will be recorded there in .imscope
files. Otherwise files are written to the directory the modem was run. This is done so that
the directory can be mapped in a docker container.
- To view recorded IQ files, use the new executable `imscope_iq_file_viewer`. This can be done by running:
```
./imscope_iq_file_viewer <path_to_iq_file>
```
Replace `<path_to_iq_file>` with the path to the IQ file you want to view.
Imscope updates
- Using imgui docking branch - allows window docking.
- Moved scopes to different windows to allow docking.
- Disabled scatterplot for time domain samples - issues with amount of
vertices caused segfaults.
- Disabled IQ heatmaps for RX IQ samples on gNB and UE - this was
incorrect and currently I don't know how to fix it. This will be
reenabled once it is.
- added a simple menu and disabled demo windows by default.

Implement run-to-completion for processSlotTX. This is achieved by using a new
dynamic_barrier_t which allows to specify callback after the first join has been
made.
Add functional DFT test
- clean up code on (i)dft calls
- add DFT test for some DFT sizes against trivial implementation: it
tests a simple square signal in only real values
- correctly scale DFT-16
See getopt(3): returns int, so store it in an int variable.
I went through all occurrences, project-wide. All return values of
getopt() should be stored in ints now.
The test was actually never executed correctly (unsigned -10 is never <= 10), and log2_approx64_ref() was not accurate enough.
Therefore replace it by directly comparing one value above and one value below each rounding boundary.
To skip the test, we use the gtest command line parameter "--gtest_filter" to filter out the unwanted test.
This parameter is described as follows:
--gtest_filter=POSITIVE_PATTERNS[-NEGATIVE_PATTERNS]
Run only the tests whose name matches one of the positive patterns but
none of the negative patterns. '?' matches any single character; '*'
matches any substring; ':' separates two patterns.
Add a new scope data source (ueTimeDomainSamples) which provides time domain samples
for antenna 0 to the scope. Add graphical representation of the data in imscope.
Removed C-define from ENABLE_IMSCOPE cmake option, the #define was unused and this way
code does not have to be recompiled when imscope enable state changes.
