It has been chosen to not include the full history of commits
from David. He included a binary version of wireshark, probably
a modified one that understands NFAPI. Wireshark is released under
the GPL license, we cannot include it in the repository. We could
have done a next commit to remove this binary. But then it would
still be present in the history of commits, which may not be allowed.
And it would take space on disk. We could edit the history to remove
wireshark entirely. But this operation is too complicated.
There was also a pcap capture file, which has nothing to do in
the history of commits and would take space on disk. There again,
it's too difficult to edit the history to remove it.
There was a file .gitignore that was also removed.
The original history can be found on David's repository:
https://gitlab.eurecom.fr/daveprice/openairinterface5g/
The branch is: nfapi-ru-rau-split.
A copy of that branch has been included in the internal OAI
repository, for those who have access to it.
The branch is the same. The last commit ID is
9106438239e0bc626ff1fa1d97d911caadd0fbb9.
You can compare the current commit with the commit 9106...
to see what differs.
The current commit has to be considered non-working.
The commit following the current commit will fix problems with
the work in the current commit.
If you use git bisect, don't spend time analyzing the current
commit.
phy_init_lte_ue_signal was renamed init_lte_ue_signal in openair1/PHY/INIT/defs.h
maybe it's the opposite that should have been done?
Functions used in one file and defined in another may have been
declared in the wrong header file.
With the new threading architecture of the UE dlsim
(and others) does not work properly anymore.
When looking at the scope, you see a difference
in PDSCH LLR display. The end is always 0 where
in the current develop branch (tag 2017.w25) it's not.
This commit attempts to fix it.
We still don't have the same behavior as in 2017.w25.
I disabled channel simulation (so that UE RX = eNB TX)
and I have one error where in 2017.w25 I have zero.
For example, here comes the output of a run of "./dlsim":
**********************SNR = 0.000000 dB (tx_lev 51.000000)**************************
Errors (1(0)/1000 0/1 0/0 0/0), Pe = (1.000000e-03,0.000000e+00,-nan,-nan), dci_errors 0/1001, Pe = 0.000000e+00 => effective rate 99.900100, normalized delay 0.001472 (1.001000)
And in 2017.w25 we have (with the same hack to disable
channel simulation):
**********************SNR = 0.000000 dB (tx_lev 51.000000)**************************
Errors (0(0)/1000 0/0 0/0 0/0), Pe = (0.000000e+00,-nan,-nan,-nan), dci_errors 0/1000, Pe = 0.000000e+00 => effective rate 100.000000, normalized delay 0.001471 (1.000000)
There may be a problem somewhere. Or there was one before and we should
have had one error and the new UE architecture fixed things and now
it's as it has to be. Hard to say at this point...
When looking at the scope we quickly see some zeros for the PDSCH
LLR, at the begining this time, not at the end. This is just when
the GUI appears and then all is fine, so this seems to be for the
first frame only. In 2017.w25 this does not happen.
- rename UE_NO_LOG to DISABLE_LOG_X
because the name is misleading. The full software
is impacted, not only the UE part
- same for compilation option ---ue-no-log
that becomes --disable-log
- keep LOG_X for the standard case, that is the
case without DISABLE_LOG_X where printf has been
put. Two reasons:
* printf is not realtime friendly
* keep behavior similar for other users who may
be troubled by different logs that don't add
any benefit to previous logs
- import RRC ASN.1 defintions from the specifications
(file openair2/RRC/LITE/MESSAGES/asn1c/ASN1_files/RRC-e10.asn)
contrary to rel8/10, all modules have been imported, maybe it's too much
to refine in case of problems
- deal with rel14 in fix_asn1
- all code that was for Rel10 is now for Rel10/Rel14
- some incompatible changes (mostly in naming) were resolved in favor
of rel14, see in openair2/RRC/LITE/defs.h
- unsure about the rlc layer, some arrays have changed (values appended),
I only changed the definition and in tests in the code, I changed
the index limit, maybe it's not enough
Rel14 is the default compilation mode.
The compilation line was:
./build_oai --eNB -w USRP
The file openairinterface5g/cmake_targets/log/lte-softmodem.Rel10.txt
has been checked and all LOG_X (and 'msg') warnings have been fixed.
