fhi_72: allow to provide dpdk_iova_mode to xran

Jaroslava Fiedlerovarequested to merge
oran-iova-config into develop
  • This MR introduces a gNB configuration option that enables users to select the desired IOVA mode for DPDK ("PA" or "VA") with dpdk_iova_mode parameters in fhi_72 configuration section. If not set, the default remains PA mode to ensure backward compatibility with existing configurations. Detailed information about IOVA modes, including their advantages and disadvantages, can be found in the DPDK documentation: Memory in DPDK Part 2: Deep Dive into IOVA
  • Using IOVA VA mode allows DPDK to run without requiring SYS_ADMIN capability for the docker container.
  • Switch to IOVA VA mode in the FHI7.2 pipeline and reduce the required capabilities for the docker container. Sample run: https://jenkins-oai.eurecom.fr/job/RAN-SA-FHI72-CN5G/1283/
