The function indicates if a primary process is alive right now.
This functionality is implemented by testing for a write-

This commit is adding a generic mechanism to support multiple IOMMU
types. For now, it's only type 1 (x86 IOMMU) and no-IOMMU (a special
VFIO mode that doesn't use IOMMU at all), but it's easily extended
by adding necessary definitions into eal_pci_init.h and a DMA
mapping function to eal_pci_vfio_
Apologies, lost the signoff from Santosh Shukla and also the commit message
still mentions the file that is now non-existent, so I'll submit a v4.
Thanks,
Anatoly

Hi Przemek,
Thanks for the quick response. Now able to get the DHCP ip's for 2
vhostuser instances and able to ping each other. Isssue was a bug in
cirros 0.3.0 images which we were using in openstack after using 0.3.1
image as given in the URL(

This work is to make DPDK ports more visible and to enable using common
Linux tools to configure DPDK ports.
Patch is based on KNI but contains only control functionality of it,
also this patch does not include any Linux kernel network driver as
part of it.
Basically with the help of a kernel mod
This kernel module is based on KNI module, but this one is stripped
version of it and only for control messages, no data transfer
functionality provided.
This Linux kernel module helps userspace application create virtual
interfaces and when a control command issued into that virtual
interface, mo
This library gets control messages form kernelspace and forwards them to
librte_ether and returns response back to the kernelspace.
Library does:
1) Trigger Linux virtual interface creation
2) Initialize the netlink socket communication
3) Provides process() API to the application that does proces
Control interface APIs added into the sample application.
To have the support corresponding kernel module (KCP) needs to be inserted.
If kernel module is not there, application will run as it is without
kernel control path support.
When KCP module inserted, running application creates a virtual L

No, we can't declare the functions with a function pointer. At least I don'
This is slow data path communication implementation based on existing KNI.
Difference is: librte_kni converted into a PMD, kdp kernel module is almost
same except all control path functionality removed and some simplification done.
Motivation is to simplify slow path data communication.
