[dpdk-users] Building a DPDK application with librte_malloc only?

[Alain Gautherot]

Hello,

I'm using DPDK2.0.0 to test memory allocation and have couple questions:

1) Is it possible to build an application with only rte_malloc (and not the other libraries/services)?
I didn't find anything in the documentation.

2) Is it possible to use DPDK on CPUs that don't have AES-NI?
Is there a way to disable that in DPDK so I can run on more mainstream CPUs?
Maybe a CONFIG_* (but couldn't find it)?

Thanks,
Alain

Yes, it is possible. in your case, you just want to use EAL.

Of course. AFAIK the only requirement for AES-NI is when using AES-NI SW 
cryptodev.
It should be disabled in default config.

Ok sounds good, I figured that EAL logging had a dependency on MEMPOOL+MBUF and was able to skip building of a whole bunch.

Thanks!
