Improve MAC docs for MCS and docker for BuildKit usage
See commits for details. The first one is for fixing an omission in
!3281, the second to clarify docker build usage.
Closes: #973
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It is superseded by the CreateWorkspace() function and task step (which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 It is superseded by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.
build_oai primarily builds UHD for OAI. Thus, a number of targets (B100,
USRP1/2, ...) can be omitted, as OAI does not run on them. Further,
disable documentation and man pages, which is typically not necessary
for the averages user, and does not need to be installed for containers.
Similarly to the parent, don't redirect log files to a file. It makes
the CI more complicated, and also raises user awareness of what is being
installed.
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).
Add the possibility to use UL slots in TDD pattern 2. For simplicity, we
require the mixed slot to be of the same symbols in pattern 1 & 2. For
UL slots, simply use the right amount of UL TDAs, depending on which
number of UL slots among pattern 1 & 2 is bigger.
One complication is the TDA for the mixed slot. The current code assumes
that k2 has to be equal or larger than (number of DL slots +1) (because
the spec says min k2=2, but we might want to schedule DSUUU). Then,
there could be for instance the following cases:
- only pattern 1: DSUUU DSUUU ...: the mixed slot has to be reached an
entire period in advance
- pattern 1 & 2: DSUUU DDDDD: normal mixed slot k2, e.g., like for 7DS2U
- pattern 1 & 2: DSUUU DDDSU: the mixed slot has to be reached
N_ul2+N_dl1+1 slots in advance
I can't think of more cases right now. To avoid unscheduled slots, I put
an assertion (which could also trivially be taken out).
Adds the capability to pack/unpack the TDD table in CONFIG.request
following both SCF222.10.02 (Tag 0x1027) and SCF222.10.04 (Tag 0x1035)
formats In the case of Aerial, the TDD table is packed following the
10.04 format, but with the 10.02 tag Prevent the packing of Digital
Beamforming table and Precoding Matrix table for Aerial
A new function get_best_ul_tda() allows to select the "best" TDA out of
a number of TDA. Specifically, get_best_ul_tda() considers in how many
RBs a given TDA might be allocated, and multiplies this number of RBs
with the number of symbols in the TDA to form a "score". The TDA with
the best "score" is selected, considering it maximizes resource usage.
In phytest scheduler, we use this function to verify that the given TDA
can be really allocated in all selected slots.
Schedule SRS longer in advance, so that it would also be enough even
with big k2 for UL TDA.
Remove useless types: we do not use the information on sched_srs
anymore, so remove it.
Check that the VRB map is free before making allocations.
