rte_mempool_create fails with --no-huge

rte_mempool_create fails with --no-huge

Hi,

I am facing problem with rte_mempool_create when running my app with -no-huge after rte_eal_init succeeds.
Note that this app works fine with hugepages but since it's purpose is unit testing certain packet processing logic, it has no requirements to have ports and the Linux may not necessarily have hugepage setup in boot arsgs.
Hence -no-huge.

To demonstrate the issue, I used DPDK 23.11 dpdk-testpmd (please ignore the fact that there are no ports. Objective is to demonstrate rte_malloc/ rte_mempool_create issue)

Running directly on Linux:

dpdk-testpmd -c 000F -n 2 --log-level=eal,8 --no-huge -m 4095 --no-pci -- -i --nb-cores=2 --total-num-mbufs=2048

Comparing with running on a VM with boot args (default_hugepagesz=2M hugepagesz=1G hugepages=4) but still using -no-huge:
Note that this VM runs on the same machine as the above Linux test.

Re: rte_mempool_create fails with --no-huge

Hi Alipour,

It looks suspicious that on the host you don't see logs about loaded drivers,
like these ones that you see inside the VM:

Can it be that DPDK on the host does not see shared libraries,
e.g. it is not installed in the system and LD_LIBRARY_PATH is not set
to shared library location?
Then mempool driver would just not be loaded to create a mempool.

RE: [**EXTERNAL**] Re: rte_mempool_create fails with --no-huge

[Alipour, Mehrdad]

Hi Dmitry,

Your observation is good!
But I have the /usr/lib/dpdk/pmds-24.0 in the LD_LIBRARY_PATH but since the host does not have a match glibc, I have to run it with ld-linux-x86-64.so.2 specifying LD_LIBRARY_PATH with equivalent --library-path.

Here is the entire cmd I use to run testpmd:

sudo /lib/ld-linux-x86-64.so.2 --library-path /lib:/usr/lib:/usr/lib/dpdk:/usr/lib/dpdk/pmds-24.0:/ciena/lib /usr/bin/dpdk-testpmd -c 000F -n 2 --log-level=eal,8 --no-huge -m 4095 --no-pci -- -i --nb-cores=2 --total-num-mbufs=2048

Despite the /lib/dpdk/pmds-24.0 libs being visible, the rte_eal_init does not load any of these shared libs while it does when I run it inside the VM.
Would appreciate if you can think of any reasons rte_eal_init does not trigger loading those shared libs in the host run instance.

Regards,
Mehrdad

"the host does not have a match glibc"
Could you clarify?

/lib ? or /usr/lib ?
Do you have a symlink between those directories?
Please make sure those paths you listed above do contain DPDK drivers.

> Would appreciate if you can think of any reasons rte_eal_init does not trigger loading those shared libs in the host run instance.

About the drivers discovery mechanism: by default, dpdk looks for
drivers in the RTE_EAL_PMD_PATH directory (this path is constructed in
config/meson.build).
You can find the value in your build env:
$ grep RTE_EAL_PMD_PATH build-mini/rte_build_config.h
#define RTE_EAL_PMD_PATH "/usr/local/lib64/dpdk/pmds-25.1"

This driver "discovery" is done regardless of the value of LD_LIBRARY_PATH.

But still, (and this could be a bit confusing), loading a driver
requires that the LD_LIBRARY_PATH gives access to other DPDK shared
libraries.

A quick check for you, you can try to strace the dpdk process (with
strace -f -e trace=file).
This is a bit verbose, but here is an example with a mini build of mine.
In my case, DPDK is not installed, so I had to set a -d option, but if
you installed DPDK on the host, no need for this option.

$ LD_LIBRARY_PATH=build-mini/lib strace -f -e trace=file
build-mini/app/dpdk-testpmd -c 3 --no-huge -m 40 -d build-mini/drivers
-a 0:0.0 --vdev net_null1 --vdev net_null2 --log-level=lib.eal:debug

RE: [**EXTERNAL**] Re: rte_mempool_create fails with --no-huge

[Alipour, Mehrdad]

Hello David/Dmitry,

After adding -d <path_of_drivers>, I can now see all the pmd shared libs loading fine and rte_mempool_create works with --no-huge.

Thanks a lot for your support!

Mehrdad

"the host does not have a match glibc"
Could you clarify?

/lib ? or /usr/lib ?
Do you have a symlink between those directories?
Please make sure those paths you listed above do contain DPDK drivers.

> Would appreciate if you can think of any reasons rte_eal_init does not trigger loading those shared libs in the host run instance.

About the drivers discovery mechanism: by default, dpdk looks for drivers in the RTE_EAL_PMD_PATH directory (this path is constructed in config/meson.build).
You can find the value in your build env:
$ grep RTE_EAL_PMD_PATH build-mini/rte_build_config.h #define RTE_EAL_PMD_PATH "/usr/local/lib64/dpdk/pmds-25.1"

This driver "discovery" is done regardless of the value of LD_LIBRARY_PATH.

Adding -d should be unneeded with a properly installed DPDK.
You should double check what I mentionned (esp. RTE_EAL_PMD_PATH must
match the pmd install path on your host).
