Re: [dpdk-users] SW Turbo Poll Mode Driver

[Ginés García Avilés]

Hi again Nicolas,
Looking for a workaround trying to solve the previous issue,
I moved to Centos 7 (as suggested here 3. SW Turbo Poll Mode Driver — Data
Plane Development Kit 21.11.0-rc0 documentation (dpdk.org)
<https://doc.dpdk.org/guides/bbdevs/turbo_sw.html>)
and after having everything installed I found an *earlier issue*  when
compiling FlexRAN:

- FlexRAN-FEC-SDK-19-04/sdk/source/phy/lib_common/common_typedef_simd.hpp(43):
error: invalid redeclaration of type name "I16vec16" (declared at line 2528
of
"/opt/intel/oneapi/compiler/2021.4.0/linux/bin/intel64/../../compiler/include/dvec.h")

- FlexRAN-FEC-SDK-19-04/sdk/source/phy/lib_common/common_typedef_simd.hpp(153):
error: invalid redeclaration of type name "I32vec8" (declared at line 2259
of
"/opt/intel/oneapi/compiler/2021.4.0/linux/bin/intel64/../../compiler/include/dvec.h")

- FlexRAN-FEC-SDK-19-04/sdk/source/phy/lib_common/common_typedef_simd.hpp(191):
error: invalid redeclaration of type name "I8vec32" (declared at line 2872
of
"/opt/intel/oneapi/compiler/2021.4.0/linux/bin/intel64/../../compiler/include/dvec.h")

Versions:
  > icc (ICC) 2021.4.0 20210910
  > icpc (ICC) 2021.4.0 20210910
  > gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)
  > g++ (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)

Steps:
  * Install Centos ICC dependencies
  * yum install intel-basekit intel-hpckit
  * . /opt/intel/oneapi/setvars.sh
 * cd 
  * ./FlexRAN-FEC-SDK19-04.sh
  * cd /FlexRAN-FEC-SDK-19-04/sdk/
  * ./create-makefiles-linux.sh
  * cd build-avx512-icc
  * make

Am I missing something to compile flexRAN SDK?

Regards,
Ginés.

[Ginés García Avilés]

Hi Nicolas,
thanks a lot for your reply.

I'm trying to build DPDK with ICC but I'm not sure why libstdc++ is not
accessible for meson. As a workaround, I'm
checking gcc in order to see whether the installation is correct or not (as
far as I know icc takes some info from gcc).

As an alternative, If I move to gcc as the compiler used by meson, I'm
getting the following error for each operation provided by FlexRAN:

  - "libldpc_encoder_5gnr.a(phy_ldpc_encoder_5gnr.cpp.o): relocation
R_X86_64_32S against `.rodata.str1.32' can not be used when making a shared
object; recompile with -fPIC"

I have checked the fPIC flag and it is already included when compiling the
turbo_sw driver.

  - Versions:
  > FlexRAN 19.04
  > DPDK 21.08
  > gcc Ubuntu 9.3.0
  > Ubuntu 20.04

Should I use gcc or icc for compiling dpdk? Any ideas about what could be
the issue in the previous environments?

Thanks a lot in advance,
Ginés.

RE: [dpdk-users] SW Turbo Poll Mode Driver

[Chautru, Nicolas]

Hi Gines,
I don’t see such issue, you probably have to make sure libstdc++ is installed 
and accessible by meson.

Hi Nicolas,
thanks a lot for your help.

However, with the latest version of DPDK I'm still facing the following issue:
  - "drivers/baseband/turbo_sw/meson.build:13:4: ERROR: C library 'libstdc++' 
not found"

These are the steps I'm actually following for the whole process:
  - Set env vars (ICC compiler, FLEXRAN_SDK, DIR_WIRELESS_SDK, ...)
  - meson x86_64-native-linux-icc
  - cd x86_64-native-linux-icc
  - meson configure -Dflexran_sdk=xxx/build-avx512-icc/install
  - ninja

Thanks in advance,
Ginés.

However, with the latest version of DPDK I'm still facing the following

These are the steps I'm actually following for the whole process:

RE: [dpdk-users] SW Turbo Poll Mode Driver

[Chautru, Nicolas]

Hi Gines, 
The only thing is to make sure to set the meson option to point to the right 
location 
See https://doc.dpdk.org/guides/bbdevs/turbo_sw.html : for instance something 
like this "meson configure -Dflexran_sdk=xxx/build-avx512-icc/install"
Then meson build framework will just link the libraries: see 
drivers\baseband\turbo_sw\meson.build which uses cc.find_library to dynamically 
find and link the libraries

[dpdk-users] SW Turbo Poll Mode Driver

[Ginés García Avilés]

Hi all,
After following the steps listed here (3. SW Turbo Poll Mode Driver — Data
Plane Development Kit 21.08.0 documentation (dpdk.org)
), using the specific
versions of
DPDK and FlexRAN, I'm facing an error while trying to run one of the bbdev
tests:
  - command:
> python2 test-bbdev.py
-e="--vdev=baseband_turbo_sw,socket_id=0,max_nb_queues=8" -c validation -v
turbo_dec_default.data
  - Error:
> "Device 0 (baseband_turbo_sw) does not support specified capabilities"

which I think is due to an incorrect linkage of DPDK and FlexRAN. I have
checked all the environmental variables pointing to the different
components  and everything seems to be correct.

Any suggestions about how to solve this problem?

Thanks a lot for your help,
Ginés.
