LIN1019-6 : DPDK requires SSE4.1 support, even when running with QEMU

Created: Oct 18, 2018 Updated: Apr 29, 2021

Resolved Date: Apr 29, 2021

Found In Version: 10.19.45.1

Severity: Standard

Applicable for: Wind River Linux LTS 19

Component/s: Userspace

Description

If you are attempting to use DPDK in a VM you must ensure that the VCPU supports SSE4.2. The default VCPU model used when running the VM with 'runqemu' does not have this support and thus attempting to use DPDK will core dump. Use the available options to 'runqemu' to ensure a suitable VCPU model is in use to avoid this.
