[dpdk-dev] DMAR fault

Hi All, I am using iommu to receive packets both from hypervisor and from VM. KVM is used for the virtualization. However, after I deliver the kernel options (iommu and pci realloc), I can not receive packets in hypervisor, but VF works fine in VM. When I tried to receive packets in hypervisor, dm

[dpdk-dev] 1 core / 1 port receiving performance discrepancy

Hi Guys, I am currently testing my code with two machines(X5650 @ 2.67GHz, 82599EB): one runs my code, and the other runs Pktgen. The first task is to see how my code performs comparing to test-pmd. Both use only one port with one core to receive packets. test-pmd uses rxonly mode. My code only re

[dpdk-dev] CPU does not support x86-64 instruction set

Hi, I am having trouble to compile the dpdk in a virtual machine. I am using KVM as a hypervisor, and guest os is ubuntu 12.10, kernel 3.5.0, x86_64. I have been using dpdk for a week and run the examples in a native platform. But when I try to move it to virtual machine, it gives me the following

[dpdk-dev] impact on only 1 hugepage

Hi All, I want to ask experts about what impacts only 1 hugepage (whatever size... maybe 4GB) can impact. Since the goal of using hugepages is to reduce the number of pages used so that the lookup speed increases. Also, the hugepage is allocated at the beginning of booting the system, it must be c

[dpdk-dev] ways to generate 40Gbps with two NICs x two ports?

Hi All, I have two NICs (82599) x two ports that are used as packet generators. I want to generate full line-rate packets (40Gbps), but Pktgen-DPDK does not seem to be able to do it when two port in a NIC are used simultaneously. Does anyone know how to generate 40Gbps without replicating packets
