Expose BR2_PACKAGE_DPDK_ENABLE_KMODS to pass Meson -Denable_kmods=.
This controls building DPDK’s out-of-tree kernel modules, which are
deprecated upstream and scheduled for removal.

Hi Maxime,
I finally had some time to test those patches. I have few comments.

Could you make this string prompt shorter and move the example in
help section? See my suggestion below.

Testing the provided example with the commands:
cat >.config <<EOF
BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_PACKAGE_DPDK=y
BR2_PACKAGE_DPDK_DRIVERS_LIST="net/virtio,net/ixgbe"
EOF
make olddefconfig
make dpdk
Fails with error:
ERROR: Unknown variable "c_args".
Could you provide an example working at least with with the
current version of dpdk in Buildroot (or the upcoming 25.11),
please?

Upstream commit [1] for example,
to be included in upcoming 25.11 release reorganized the
structure of the driver directory. So this command to list the
possible drivers might need to be updated after the bump to 25.11.
Also playing a bit with those new options, I noticed enabling
a dpdk component does not enable its internal dpdk dependencies.
So I would suggest to add a comment about that in the help.
With those comments, I suggest the following:
string "List of enabled drivers"
help
Controls which DPDK drivers are built.
Accepted values:
(empty): use DPDK defaults
none : build no drivers
list : comma-separated list of drivers to enable
e.g. "net/virtio,net/ixgbe"
To list all drivers found in the DPDK source tree:
find drivers -mindepth 2 -maxdepth 2 -type d \
! -printf '%P\n' | sort
Note: providing manually a list of dpdk component to enable
does not automatically enable its dependencies (internal or
external). It is the user responsiblity to add internal dpdk
dependencies in this list, and/or select the relevant
Buildroot packages for external dependencies. DPDK
configuration will fail in case of missing dependencies.
Please adjust as needed.

With the upstream commit [1], will this '*/*' still work with
a dpdk version 25.11?

Since the new dpdk version is expected soon, I suggest you
should test those updated patches with it. And possibly
send all those in the same series including the bump.
Best regards,
Julien.

Hi Maxime,
I have mostly the same comments as for the dpdk driver
list patch [1].

Could you make the prompt a bit shorter by moving the example
in the help section. For example:
string "List of enabled applications"

Could you add a comment in the help section about the
dependencies?

Could you send an updated patch to address those issues, please?
Best regards,

Thanks for sharing with tests.

It is a good idea. It helps to save CO2 and to have quicker compilation
on the targets.
What's about a free definition of DPDK_CONF_OPTS= too ?
For instance:
DPDK_CONF_OPTS += -Dc_args='-DRTE_LOG_DP_LEVEL=RTE_LOG_DEBUG'
It would be useful tune those for the DPDK too.
It is a minor improvement, it does not prevent from merging into
Buildroot.
LGTM.
