[dpdk-users] DPDK pinned Memory for non Root User

[dpdk-users] DPDK pinned Memory for non Root User

[Karthi M]

Hi All, 
	
		I’m trying to run DPDK examples/App in a non-root user mode. rte_mempool_init always returns 0MB Available memory. But if I run the same as a root user, everything works fine. So I’m not able to get the pinned memory for the App to start as a unprivileged user. So is there a way for App to get pinned memory for the users other than the root user.  Can Someone help me out on this and I have come across some similar issue DPDK mail thread for the same issue.

i am assuming that you are on linux. ​afaik there is no way to ​run dpdk as
non-root. the thread you linked to has necessary information...

In the beginning was the lambda, and the lambda was with Emacs, and Emacs
was the lambda.

There is possible way, as documented here:
http://dpdk.org/doc/guides/linux_gsg/enable_func.html#running-dpdk-applications-without-root-privileges

But I haven't tried it myself and neither do I know if it will solve your problem.

​yeah it says that but afaik, ​/proc/self/pagemap cannot be opened (during
init) due to virt2phys translation issues...
