SYS_NICE is a capability that allows a process to set thread affinity
and priority, among other things (see capabilities(7) for more info).
In this commit, add a function that allows to determine if the process
has this capability, and try to change the thread affinity and priority,
if requested. If the capability does not exist, the function will simply
not attempt to change the corresponding thread attributes.
To determine if the process has SYS_NICE, libcap can be used. However,
it might not be installed by default. To avoid requiring another
dependency, if we detect that libcap is not present, use a workaround by
try to set a real-time scheduling policy; if it's present, or can be
changed, we assume that the process has SYS_NICE (and clean up, if
relevant).
Simplify reading of capabilities
Use a common structure nr_lc_config_t to group LC configuration for one
logical channel. Use seq_arr for simple lookup, adding, removing of
elements without manual indexing logic.
This commit retains the previous logic of adding/releasing LCs through
the process_CellGroupConfig(), although we know while building the
CellGroupConfig if we add/release LCs. The next commit fixes this.
-rdynamic is necessary for clang as well to properly link shared
executables. Add furthermore an option to ignore unused command line
arguments, to suppress warning
clang: warning: argument unused during compilation: '-rdynamic' [-Wunused-command-line-argument]
This is likely because -rdynamic is only relevant for the linker, but
the corresponding option add_link_options() is only available starting
cmake 3.13, while we are still at 3.12 (for Ubuntu 18, to my
understanding).
- Phy configuration will be prepared by MAC
- Sidelink preconfiguration parameters passed from RRC->MAC
- Only 1 SSB TA allocation used
- psbch payload prepared by MAC after receiving the tx slss req
- e2_ran_func library divided into e2_ran_func_cuup (CU-UP only) and e2_ran_func_du_cucp_cuup (DU, CU, CU-CP and gNB-mono)
- GTP SM is not yet implemented in CU-UP -> CU-UP doesn't store PDU session information
- PDCP SM support for gNB-mono, CU and CU-UP
- KPM SM support for all node types (DU, CU, CU-UP, CU-CP and gNB-mono)
remove several unused files
remove mem_block_t that is never used in a different way than a simple heap buffer
move up IP address type and remove duplications of the same struct declaration
A later commit will introduce an RB tree to manage multiple CU-UPs. The
RB tree implementation relies on some macros that generate RB tree
functions. Functions using the RB tree implementation will be grouped in
this file.
- avoid the finction duplication
- add the transform predoding to the nr_rx_pusch_tp
- add the MMSE for 2 layer which modulation greater than 16 qam
- can support to 256 qam for 1 layer and 2 layer
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
The MAC_NR target is not needed; every dependent target also links
L2_NR. Therefore, this target just creates double compilation. We can
remove it without problems.
As described in common/utils/config.h, it is possible to hook into the
asn1c tracing mechanism to print logs.
This commit fixes a regression to print theses traces properly in OAI.
Above-mentioned file explains also how to reduce the amount of logs,
e.g., for single code blocks.
