[dpdk-dev] DPDK and ASLR

[Assaad, Sami (Sami)]

When I operate a DPDK based application, the EAL always reports the following:
EAL: WARNING: Address Space Layout Randomization (ASLR) is enabled in the kernel.
EAL:      This may cause issues with mapping memory into secondary processes.

Our application is DPDK client/server based and runs properly.

My questions are:

*         Is this warning of any importance?

*         Should ASLR be disabled?

*         Does ASLR affect DPDK performance?

Issue Update: 7. Re: How do you setup a VM in Promiscuous Mode using PCI

      Pass-Through (SR-IOV)? (Qiu, Michael)

The problem I had was due to the fact that RMRR was used by the HOST for the HP 10G NIC card; which prevented me from performing a PCI Pass-Through.
HP provided a BIOS and NIC Firmware update to resolve this.  It is to note that an Intel NIC having an 82599 Ethernet Controller did not generate the RMRR issue!
