Here¡¯s a draft for your email that you can send to inquire about resolving the RDSEED issue with DPDK:
________________________________
Subject: Inquiry Regarding DPDK RDSEED Support on Non-RDSEED Machines
Dear DPDK Development Team,
I hope this message finds you well.
I am currently facing an issue while building and running a DPDK 21.05 application on Intel x86 machines that have RDSEED in the CPU flags. We also need to run this application on machines that do not support RDSEED, which leads to the following fatal error:

ERROR: This system does not support "RDSEED".
Please check that RTE_MACHINE is set correctly.
EAL: FATAL: unsupported cpu type.


To address this, I attempted to add the -Dplatform=haswell option while running Meson, as I understand that Haswell is the last architecture without RDSEED support. However, I am still encountering the same error.
Currently, our workaround is to modify the error handling in rte_cpu_is_supported() to print a warning instead of exiting the application. However, this is not an ideal solution for us.
Given that we do not have direct access to automated build machines and must go through a change request process, it would be helpful to know if there is a more effective Meson configuration option (such as machine=haswell or anything else) that could help us resolve this issue.
I appreciate any guidance or suggestions you can provide to help us navigate this challenge.
Thank you in advance for your assistance!
Best regards,
wyf
