RFSim test for 10 UEs/process
This MR adds a testcase and changes required to run 10 UEs in a single
process with RFSim
- Added deregistration for all connected UEs
- Refactored MAC/RRC instance handling
- made map_current_symbol thread safe
- made opeanir0_cfg thread safe and local
- Added 10UE/process testcase
Update RFsim CN
- Update RFsim CNs to latest version
- update the MBIM stop script to remove IP addresses (we don't use this
script directly, so it does not have an impact)
The CI detects whether a UE connected (and has a PDU session) by trying
to read the IP address. It therefore assumes that as long as the UE is
not connected, no IP would be present.
With the existing stop_quectel_mbim.sh script, this was not the case; it
would simply leave the IP address. Modify this script to flush all IP
addresses on disconnect to remedy this.
RF emulator and improvements of the timers
RF emulator:
Add an RF library emulating a real device without the need of a real
device. This is thought to enable using phy-test without requiring a
radio device or channel simulation. The library synchronizes on the
real time clock, drops TX and generate noise on RX. Noise generation
can be disabled and the noise level configured.
Timers improvements:
- Fix standard deviation for merged timers
- Add display of ULSCH decoding timers
- Add decoding timer in AAL
CI: speed up and simplify build, remove unnecessary Python code, remove --eNB* parameter list
This cleans up the CI framework for running end-to-end tests, and
improves the integration with OAI code. Specifically
- cleanup build_oai and helpers to output all text, which is captured
better by the CI
- build some images in the Cluster-Build in parallel to increase speed
- remove all --eNB{,1,2}{IPAddress,UserName,Password} variables. Those
were indexed through "instance" and "server ID" and are replaced with
the actual node name. I consider further cleanup to introduce a
"global" XML file node name so we don't need this in each step and
instead define this once.
- individual cleanup
A previous commit changed to use archiveArtifact() to recover CI logs,
and then attempted to "guess" the L1/MAC stats file name through a
regex. However, the format "enb-[0-9]+" is not correct, as
archiveArtifact() puts the task ID ("[0-9]+") BEFORE the file name
(here, "enb"). So, make it more generic and match the final "-enb.log"
("$" means "end of string").
Fixes: 244ea8fc22 ("Use archiveArtifact() for TerminateeNB()")
Many of these tests exit with an exit code != 0. Thus, the CI
automatically logs the result. Rather, write everything including stderr
to the file for analysis.
Also, rewrite the file with ">" instead of appending through ">>". While
appending works because the CI removes files after archiving, it seems
"cleaner" to remove files.
It is superseded by the CreateWorkspace() function and task step (which
removes and recreates a workspace), and this option was not actually
used in any function except for the build of unit tests, but no XML
step actually specified this option.
After having transitioned to direct node names in the XML, these
parameters are not relevant anymore.
The best way to view this patch is with
git show <SHA> --ignore-all-space
Remove this class. It is not safe to use (no return codes, can get out
of sync), hardcodes the use of passwords, and it's API is cumbersone.
More explanations can also be found in !1867. It is superseded by
cls_cmd.py
Since 28ce0dc444 ("Main: pass in ctx"), the CI always collects logs
into cmake_targets/log/. Hence, LogCollecteNB() is never called. We can
remove it.
Further, change the cmake_targets/log/ to ci-log/, which is shorter, and
append a / on the zip path to make sure that only contents is zipped.
Reimplement these functions by
- using cls_cmd
- retain only the necessary steps from the timing-phytest function
- pass in ctx and node information, instead of server ID
- remove all superfluous variables that don't seem to be used
- make some lists (corresponding indices are "server ID") into normal
variables.
Pass node directly from XML to these functions
- BuildClusterImage()
- BuildImage()
- BuildProxy()
- BuildRunTests()
instead of reading the "server ID" and looking up from
eNB_IPAddress/eNB1_IPAddress/eNB2_IPAddress.
Improve the proxy build unit test by properly passing ctx information.
Refactor ULSCH scheduler towards more TDD pattern flexibility
Refactors ULSCH scheduler, notably to support "UL-heavy" TDD patterns,
e.g., DSUUU. Also allows to run TDD pattern2 with UL slots, which was a
limitation in the previous code.
Increase the number of aggregration level candidates. Since we have many
UEs with concurrent traffic in that pipeline, we should ensure that we
can allocate many DCIs to not waste resources (e.g., not all RBs used
because could not find DCIs for specific UEs).
Make Amarisoft UE sim a RedCap UE
Change Amarisoft UE configuration and gNB of the AW2S pipeline to
be/handle RedCap UEs.
The UE should only connect if the gNB handles RedCap UEs. In the logs,
we should see
[MAC] UE with RNTI 3725 is RedCap
which we check for the first two UEs (one normal UE/absence of this
message, one RedCap UE/presence of this message).
Since the parent commit, UE 1 is normal (no RedCap), UE 2 is RedCap.
Verify that the gNB agrees with that and detects the second UE as RedCap
by analyzing some logs.
The first check is a bit elaborate, but basically is
[ $(docker logs | grep XYZ | wc -l) -eq 0 ]
^ ^ ^ ^ ^
1 2 3 4 5
(1) is the if statement, that compares
(4) the number of occurrences
(3) of "RedCap" in the
(2) docker logs
(5) to being equal to
Note for all UEs which number, and whether it is RedCap (so this need to
be kept in sync with the Amarisoft UE sim configuration file in use!).
