See e.g., egrep(1) [https://linux.die.net/man/1/egrep]:

See also the rationale of the POSIX description of grep
(https://pubs.opengroup.org/onlinepubs/9699919799/utilities/grep.html):
> This grep has been enhanced in an upwards-compatible way to provide
> the exact functionality of the historical egrep and fgrep commands as

> consolidate the three greps into a single command.
Closes: #839
The default values set by xran for DPDK socket memory/limit is 8192. It
is changed when the variable for the memory size, given down to xran, is
non-zero (cf also previous patch). Since the last patch, if nothing is
given in OAI configuration, OAI will pass down a size of 8192. However,
a configuration value of 0 is a valid choice (it is a pre-allocation,
DPDK will allocate dynamically), so modify the default in xran to be 0
so that all sizes, including 0, can be given to DPDK.
Note that the currently used implementation of xran will always try to
allocate this memory on NUMA node 0. If you want to use another one,
this field has to be set to 0 (no pre-allocation), and DPDK will
allocate it dynamically.

Build on ARM fails in the previous version, while the current master
(1a09d3bc) works. So let's update to a newer version to avoid problems
on ARM, and assuming x86 works.
This commit introduces a substitute module library for setting up softmodems using YAML instead of libconfig.
The softmodems should work the same with both types of files. Extra care was put to make sure the behavior
of both modules is the same.
Example yaml config files were added for the UE and gNB
At least in Eurecom, there are no RHEL 7/CentOS 7+8 servers. Existing
installations will work, but we don't want to encourage people to use
these old distributions, so remove it. Also, they reached EOL
Add CentOS stream as an alternative.
I don't know about any user of the kernel modules. It is effectively
legacy code we carry around, for no good reason. Remove it for the
moment. If we ever need it, we can revert.
Ubuntu 18.04 is now in "Extended Security Maintenance", but otherwise
gets no updates. Remove it from supported distributions (regarding
installing packages); users can of course still use it.
Users are encouraged to upgrade to Ubuntu 20+.
Apart from the obvious change of adding ubuntu24.04 to supported
distributions, we need to remove liblapacke-dev as it is incompatible
with libatlas3-base. Installing both aborts with:
The following packages have unmet dependencies:
liblapacke : Breaks: libatlas3-base (< 3.10.3-14) but 3.10.3-13ubuntu1 is to be installed
It seems that we don't need it though, as liblapacke-dev installs the
right atlas library as a dependency.
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.

- 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.

This enables build_oai to detect if the output terminal supports colors.
If it does, it will use colors in its output. If it does not, it will
just print the text, without color codes, improving legibility.
Some distributions, e.g., CentOS8 or RHEL8, ship with an old cmake
(v2.8). To provide a newer, they have a separate cmake3 package, where a
recent cmake version is in program cmake3. To be agnostic, build_helper
detects the distribution and choses the cmake program to use.
This commit uses the correct cmake, which is provided in the environment
variable $CMAKE.
