Hi Everyone,
I am running a DPDK based application on a centOS VM, which uses
uio_pci_generic DPDK driver for IO operations. The VM is hosted on a centOS
bare-metal. When I try to run, the application crashes and generates a
core-dump.
In the application flow, I fetch the port info using rte_eth_dev_info_get()
and initialize the DPDK port, it works fine.As part of application logic I
am fetching the port info using the same API rte_eth_dev_info_get() in
another thread, but the application is crashing while invoking this API.
Below are the VM configuration:
1.
DPDK version: 20.11
2.
KERNEL DRIVER: virtio
3.
DPDK DRIVER: uio_pci_generic
4.
VM OS: CentOS 7.9
5.
RAM: 8GB
6.
CPU: 9
Below are the BM configuration:
1.
QEMU-KVM version: 1.5.3
2.
Host OS: CentOS 7.9
The same application flow works fine in below combinations:
1.
With vfio-pci DPDK driver and same VM and host configuration
2.
The host OS is Ubuntu 20.04 and the QEMU-KVM version is 4.2.2.
Could anyone please help me resolve this issue.
Thank you,
Somesh
