Hi,all,


I am developing a program now. My program have two kinds of processes. Process A and process B.
Process A receives packets from nic and then forward packets to process B. While process B will do some user-mode TCP/IP stack work.


So here the problem is,
For hugepages between A and nic, A is primary.
For hugepages between A and B, I hope that B could be primary and A could be secondary.
Because there may be many process Bs in some situations.Also I want to make Memory Operations restricted with B only. Memory malloc and free operate in B only. Process A just attach shared memory and use.


So does dpdk support a process start as primary &amp; secondary both? OR is this on a roadmap?


Any help will be greatly appreciated.

No, it doesn't. You can either have primary and secondary or multiple
primaries. Can you explain why B can't be your primary? If you just allow
it to configure all the nic pools that should solve your issue.

Hi£¬all
&nbsp; &nbsp; &nbsp;
&nbsp; &nbsp; &nbsp;I want to compile librte_eal with static link of libc.a.
&nbsp; &nbsp; &nbsp;I have tried to add&nbsp;
&nbsp; &nbsp; &nbsp;LDLIBS += -Wl,-Bstatic -lc -Wl,-Bdynamic&nbsp; &nbsp; &nbsp;in dpdk-19.11/lib/librte_eal/linux/eal/Makefile


&nbsp; &nbsp; &nbsp;compile ok, but my program meet SIGSEGV when start.
&nbsp; &nbsp; &nbsp;core dump at getauxval()...


&nbsp; &nbsp; &nbsp;So i wanna ask how to make compile with static link of libc work.
