Reset all the circular buffer to zero; this ensures that we cannot read
uninitialized data. Since this is RFsimulator, performance is not a
problem here either (and zeroing out happens only once).
Add an API to allow out-of-order writes to a radio interface, unlike the
current interface.
this function is called in UE in this commit, even if the tx might
still be in order.
Later, i plan to improve UE pulti-threading, that will lead to out of
order tx. also, the gNB will benefit of this new function to replace
several specific pieces of code that reorder tx with over complex and
slow systems
Use the correct function in order to close open RFsim connections,
instead of a simple close(). If this is not done correctly, it might
happen that the softmodem closes, but an L1 thread might still read
samples (bug in higher layers). Then, RFsim tries to read a socket
(because it has an open connection), but the actual connection had been
close()d. This commit fixes this behavior.
- deleted: ../../../executables/rfsim.c
- removed unused command line options to set SINR and SNR
- removed unused functions to get SINR and SNR
- removed unused RFSIM struct members
Disable DPDK telemetry to skip creation of one/two threads (depending on
DPDK version). To force users to do this, bump the version of the patch
checked by cmake.

Force the CPU affinity for ru_thread explicitly to ru_thread_core. It is
already done via threadCreate(), but force again as per change request.
Delete commented 7.2 code that did the equivalent. We cannot set it in
the driver, as we don't have access to variable ru->ru_thread_core.
Closes: #732 (suggestion 2)

system_core is the core reserved for DPDK control threads. It was
hardcoded to 0, but it seems that one some systems, CPU 0 cannot be
reasonably isolated from kernel threads. Make it therefore configurable
(default: 0)

- Add the O-RAN 7.2 FHI library, interfacing with OSC xRAN library (E
release)
- Add Findxran.cmake to detect the library and headers, including
version information
- Test for numa and DPDK presence
- Add patch for OSC xRAN to make interworking possible
- Add sample config files for LiteOn, Benetel, and VVDN units.
Documentation is provided in the next commit.

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.
- Add TOC
- Better describe what RFsim does
- Remove misleading, wrong, unnecessary information
* It is futile to mention --phy-test or other modes, RFsim works with
all
* Explaining how to ping is not the task of the RFsim documentation
(that is what tutorials are for)
* Remove useless/outdated build log information
- Add some more information on which flags to run
- Improve formatting, and minor clarifications
We set the RFsim TCP socket to non-blocking. Thus, it may happen that we
cannot write() to the socket when the kernel cannot handle the request,
in which case we wait some time before trying again. This is the
correct/expected behavior.
Since this is *normal*, an error message is not justified; we did not
even print a message in this case before commit 21790f9c4f introduced it.
Testing on Neoverse N1 (Ampere 3GHz). Tested only on a subset of phy-simulators.
- Changes:
- use SIMDE consistently
- adaptations of LDPC decoder generator for ARMv8 performance
- SIMDe modifications of Intel CRC to allow for aarch64 build.
optimizations for 128-bit to improve performance of LDPC encode/decode
on aarch64 (Neoverse 1)
- added BG2 files for 128-bit ldpc encoder (aarch64)
- testing on Xeon
- testing on x86
- minor changes to build/run on x86
- change in crc.h after returning to aarch64
- removed some warning in ldpc decoder generator for x86_64
- char
- Delete irrelevant constants
- Correctly declare variables
- Define stdbool for all architectures
- Remove definition of _MM_SHUFFLE and use SIMDE_MM_SHUFFLE
- Remove commented code
- Fix CMakeLists.txt
- Include SIMDE avx2 functions in tools_defs.h
This improves the RFsimulator code to reach a ~40% E2E throughput
improvement (depending on the machines).
Changes:
- reduce ring buffer size
- code cleanup for readability
- set TCP kernel parameters
Config options --reconfig_file and --rbconfig-file have been introduced
to modify the filenames of reconfig.raw and rbconfig.raw (e.g., in the
case of multiple UEs). These filen*ames* were to be prepended with
--rrc_config_path to set the path. In summary, three options were
necessary, when two are sufficient.
In this commit, change to the options --reconfig-file and
--rbconfig-file (slight change for harmonization with other options,
which mostly use dashes) to give the full path to the corresponding
files, and avoid to surprise users who would not expect to have three
options.
--rrc_config_path has been deprecated and an error will be printed if a
user attempts to use it.
For FR2 and including analog beamforming, we control the beams via GPIO
on radio units.
In this commit, introduce a configuration option to switch the GPIO
control for different devices: "generic" is the current GPIO control,
"interdigital" configures the GPIO configuration to be used with an
InterDigital device.
