- Rate matching performed by card
- Due to rate matching on card, small TBs are encoded correctly, so the
limitation of encoding small TBs in CPU can be lifted (all TBs encoded
on T2), see a later commits
- CU-CP replying to the CU-UP with a Setup Failure message in case of unsuccessfull E1 Setup Request
- message is decoded by the CU-UP, and stops the process
This commit removes nr_rrc_mac_config_req_ue_logicalChannelBearer and handles configuration of logical channel bearers at MAC in nr_rrc_mac_config_req_cg.
This also avoids to configure LCs before resetting them again nr_rrc_mac_config_req_cg().
- update library location
- correct information for ioWorker
- disable HT on servers
- add local/lib trick for Fedora-based OS. Also clean-up on line terminations
- add another pkg-config trick.
- Proper version(s) of DPDK
- Support for both Bronze and E releases
- Minor fixes on E-patches and build system
- fixed a few typos and better explanation of the CPU allocation scheme

For the initialization of the xran library (split 7.2), we need some
parameters such as PRACH or frame config. However, to date,
initialization of split at level 7 use the split 8 openair0_config
structure, which does not have the necessary information.
Hence, add a single structure that contains that information.
* make a single call to various function
* make fill_rf_config() static, it is only used in this file
* do not initialize the number of antennas in openair0_cfg in
init_NR_RU(), as it is already done in fill_rf_config()
Harmonize the call to openair0_transport_load(), by putting it in a
single place instead of multiple calls
Further, delay the call to ru_thread, for two reasons:
1) it is somewhat "symmetric" with local RF, which is done there as well
2) for the xran library, we need to read some parameters such as PRACH,
frame format, etc. At the RU, the corresponding FAPI config request
parameter structure is copied from the gNB to RU at the beginning of
the ru_thread, so we have to wait for that to happen.
Reformat code to properly copy memory if we skip precoding.
precoding_stats timing is not part of ru->feptx_ofdm, but
ru->feptx_prec, so always print it.
Previously, in order to speed up processing if precoding is disabled, we
just copy the pointer from txdataF to txdataF_BF, as opposed to do a
full memcpy() to duplicate the data. The same happens if we cannot have
precoding, i.e., in SISO. This has implications such as memory leaks,
which is why this is not being done. However, the code comment is
intentionally placed there.
For 7.2 FH, some RUs do phase compensation, whereas for others, the DU
does it. In fact, this can be "negotiated" using the M plane. Since we
don't have the M plane yet, add a configuration option to set where
phase compensation is performed.
For certain processing, e.g., in the case of FH 7.2, we need to ensure
that critical L1 processing happens fast. Try to force speedy processing
with this high priority.
