Hi All We're trying to run testpmd application on HP Proliant DL380P Gen 8 server. We've enabled SR-IOV in BIOS and set appropriate flags when booting kernel (iommu=pt intel_iommu=on) The NIC we are using is 82599EB (2 ports, 10Gb SFP+)
When running testpmd application we always encouter DMAR error in dmesg [ 186.302866] dmar: DRHD: handling fault status reg 2 [ 186.302872] dmar: DMAR:[DMA Read] Request device [07:00.1] fault addr 1f73220000 [ 186.302872] DMAR:[fault reason 06] PTE Read access is not set [ 186.302875] dmar: DMAR:[DMA Read] Request device [07:00.0] fault addr 1f73200000 [ 186.302875] DMAR:[fault reason 06] PTE Read access is not set [ 324.759520] dmar: DRHD: handling fault status reg 202 [ 324.759525] dmar: DMAR:[DMA Read] Request device [07:00.1] fault addr 1f73220000 [ 324.759525] DMAR:[fault reason 06] PTE Read access is not set [ 324.759528] dmar: DMAR:[DMA Read] Request device [07:00.0] fault addr 1f73200000 [ 324.759528] DMAR:[fault reason 06] PTE Read access is not set Has anyone encountered this issue? Tried to search through gmane and google and the only solution was to disable SR-IOV which we cannot do.
