Here=A1=AFs a draft for your email that you can send to inquire about resol= ving 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 appl= ication on Intel x86 machines that have RDSEED in the CPU flags. We also ne= ed to run this application on machines that do not support RDSEED, which le= ads to the following fatal error:
<=
div style=3D"direction: ltr; font-family: Aptos, Aptos_EmbeddedFont, Aptos_=
MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(=
0, 0, 0);">ERROR: This system does not support "RDSEED".=0A=
Please check that RTE_MACHINE is set correctly.=0A=
EAL: FATAL: unsupported cpu type.=0A=
To address this, I attempted to add the -Dplatform=3Dhaswell&n= bsp;option while running Meson, as I understand that Haswell is the last ar= chitecture without RDSEED support. However, I am still encountering the sam= e error.
Currently, our workaround is to modify the error handling in rte_cpu_= is_supported() to print a warning instead of exiting the applic= ation. However, this is not an ideal solution for us.
Given that we do not have direct access to automated build machines and mus= t go through a change request process, it would be helpful to know if there= is a more effective Meson configuration option (such as machine=3Dhaswell or anything else) that could help us re= solve this issue.
I appreciate any guidance or suggestions you can provide to help us navigat= e this challenge.
Thank you in advance for your assistance!
Best regards,
wyf
