uhd installation issue when DPDK=ON #754

Closed houshangaziziaccelleran closed 1 month ago

houshangaziziaccelleran commented 5 months ago

Hello Can you please help with the attached uhd installation issue? Thanks Houshang uhd_installation.txt

NI-LAm commented 5 months ago

Looks like you miss some DPDK packages. Did you installed them?

sudo apt install dpdk dpdk-dev

This is the UHD issue tracker. Questions like this are better asked in the mailing list (more readers, quicker response time). https://kb.ettus.com/Mailing_Lists#usrp-users.

Hello It did not help. Please see the new screenshot attached. Thanks uhd-error.txt

houshangaziziaccelleran commented 5 months ago

in line 270 on uhd/host/lib/transport/uhd-dpdk/dpdk_io_service.cpp removed:

rte_thread_setname(pthread_self(), name);

and added below instead

#if (RTE_VER_YEAR >= 23)
        rte_thread_set_name(rte_thread_self(), name);
#else
            rte_thread_setname(pthread_self(), name);
#endif

Hello Please see below. As you can see, when use_dpdk argument is there, benchmark_rate fails no matter if it is 0 or 1.

Hi @houshangaziziaccelleran,

When using the UHD-4.6 branch, please cherry-pick 85e4b53a0d0715500a74db1f9b9cc234e5c6f4ef to fix the compile issue you are seeing. In the UHD-4.7 branch, the fix is already included.

However, for certain network cards, UHD 4.6 and 4.7 has an incompatibility with DPDK >= 22.11. In case you see the following error when initializing the device

[ERROR] [UHD] Device discovery error: vector::_M_range_check: __n (which is 4294967295) >= this->size() (which is 1)

then you additionally need to cherry-pick 8305d925176fed1fd7f375e3ae8d9de0b72b04d4. This fix was added to the master branch recently.

If you still have issues, please carefully check your configuration files, see https://uhd.readthedocs.io/en/latest/page_dpdk.html

For extended logging, I suggest the following:
