[dpdk-dev] disable hugepages
I tried using the following dpdk options: --no-huge --vdev eth_pcap0 ,rx_pcap=/t1,tx_pcap=/t2 *It's worked but the number of elements is limited, although the machine has enough free memory. *rte_mempool_create is failed when I'm trying to allocate more memory. Is there any limitation on the memory beside the machine? *Thanks, Keren * On Wed, Nov 9, 2016 at 4:50 PM, Olivier Matz wrote: > Hi Keren, > > On 11/09/2016 03:40 PM, Keren Hochman wrote: > > On Wed, Nov 9, 2016 at 3:40 PM, Christian Ehrhardt < > > christian.ehrhardt at canonical.com> wrote: > > > >> > >> On Wed, Nov 9, 2016 at 1:55 PM, Keren Hochman < > >> keren.hochman at lightcyber.com> wrote: > >> > >>> how can I create mempool without hugepages?My application is running > on a > >>> pcap file so no huge pages is needed ? > >>> > >> > >> Not sure if that is what you really want (Debug use only), but in > general > >> no-huge is available as EAL arg > >> > >> From http://pktgen.readthedocs.io/en/latest/usage_eal.html : > >> > >> EAL options for DEBUG use only: > >> --no-huge : Use malloc instead of hugetlbfs > >> > > I need this option only for testing.

[dpdk-dev] disable hugepages
I need this option only for testing. How can I use rte_mempool_create if I use --no-huge?

[dpdk-dev] Running 2 process on the same machine
Also, I can't understand how to define socket-mem. I did not see anything related to hugepages in /etc/sysctl.conf. Can i mount hugepages to 2 different dirs instead and use --huge-dir ? Thank you.

Thank you for your response, I still can not run the 2 process together. if I add --no-pci to one process it can replace white and black lists right?

[dpdk-dev] Running 2 process on the same machine
Hi, I need to run 2 process that uses dpdk on the same machine. One uses dpdk drivers, and the other just read from a pcap file. If I disable hugepages in the second process rte_mempool_create fails. What is the correct way to handle this? Thanks, Keren
[dpdk-dev] Run 2 different testpmd from the same machine
Hi, I tried to run 2 instances of testpmd from the same machine but received a message: Cannot get hugepage information when I tried to run the second instance. Is there a way to disable hugepages or allow to instances to access it ? Thanks. keren
[dpdk-dev] imissed in rte_pmd_pcap
Hello, in the dpdk pcap driver, the imissed indicator of rte_eth_stats structure is not increasing even when we miss packets since there are no available mbufs. I looked at the code and I saw that nothing increase it in the pcap driver code ( as opposed to other drivers where it's being promoted) Is there a reason for that? Is there other way to follow missed packets when using libpcap ? Thanks, Keren
[dpdk-dev] support BCM5719 driver
Hi, I tried to bind BCM5719 driver to DPDK compatible driver: (I tried both to uio_pci_generic and igb_uio) Network devices using DPDK-compatible driver :03:00.2 'NetXtreme BCM5719 Gigabit Ethernet PCIe' drv=uio_pci_generic unused=tg3,igb_uio :03:00.3 'NetXtreme BCM5719 Gigabit Ethernet PCIe' drv=igb_uio unused=tg3,uio_pci_generic But when I ran from the dpdk example: link_status_interrupt I received an error No ethernet port. (When I tried to bind I350 Gigabit Network Connection it worked. Thank you, Keren
