Let's just not install it in the images, and a user will either write a recipe for their image or create a SDK image to which they can trivially add dpdk. Ross, DPDK suite comes with library and sample application that in past release run out-of-box to demonstrate the feature. Romley crystal-forest are communication grade platform which is expected to have both DPDK and QAT technology demonstrated. The challenge is if we don't have the features examples pre-installed on the sample image that is packaged into release tarball, customer have to build them from scratch to try out the DPDK examples. Yes, I do agree that it is trivial. I do agree that customer sample app is still need to be compiled against the shared library. So, they will have to rebuild some image again. I am looping in CID TME to give in their opinion on this subject matter as he owns the supporting customer part just to check with him whether it is ok to leave the trivial change to end-customer who is using yocto to do that themselves. If I remember correctly, that will require some documentation update on their end too. Thanks for the response anyway, let's do what is right and also convenient for the user... I believe that we can reach some agreement here Joel Abhishek, What is your thought of not having DPDK QAT technology pre-installed on the core-image-sato core-image-sato-sdk images? Do you think that your customer will follow some recommendation documented in manual to add them into their build recipe to add in DPDK and DPDK samples? Do take note that, in the past on the NDA recipe that was released out in previous product line, DPDK QAT are preinstalled onto the core-image-sato binary that is released as test image. What is your thought there? -- ___ meta-intel mailing list meta-intel@yoctoproject.org https://lists.yoctoproject.org/listinfo/meta-intel

Hi Sreeju,
Aren¹t there other BSPs such as crystalforest which can utilize the DPDK
feature?

Hi Nitin,
Yes, it can be utilized in crystalforest, highlandforest and mohonpeak.

On their own, the DPDK packages are useless as the user needs to compile their application with them.
