Please have a look at the ci. Unit tests are failing with this patch because the default is changed from VA to PA. A quick way to reproduce is to run vdev unit tests as a normal user in no huge mode. Before change: $ DPDK_TEST=vdev_autotest ./build-gcc/app/test/dpdk-test --no-huge -m 2048 --log-level=*:debug ... EAL: Bus vdev wants IOVA as 'DC' EAL: Bus pci wants IOVA as 'DC' EAL: Buses did not request a specific IOVA mode. EAL: Physical addresses are unavailable, selecting IOVA as VA mode. EAL: Selected IOVA mode 'VA' After change: $ DPDK_TEST=vdev_autotest ./build-gcc/app/test/dpdk-test --no-huge -m 2048 --log-level=*:debug ... EAL: Bus vdev wants IOVA as 'DC' EAL: Bus pci wants IOVA as 'PA' EAL: FATAL: Cannot use IOVA as 'PA' since physical addresses are not available EAL: Cannot use IOVA as 'PA' since physical addresses are not available -- David Marchand
