Hi Dave and Damjan,
Yes, as I confirmed before, the patch works, but I just discovered a side
effect introduced by this patch.
That is, DPDK in-memory implys no shared config, then
rte_eal_init/rte_eal_config_create will not check if another DPDK process is
running. Therefore, we could run
David,
I believe you are right, it is possible to get into a dead lock between worker
A and B in the case where A is waiting for B and B is waiting for A.
We solved that by tail drop. Another way of doing that is by using a separate
handover worker from NAT worker.
We are exploring some new
*Hi Damjan*
*Thnaks for your answer,*
*I think it is possible (I encountered this problem) to have deadlock even when
I use separate CPU for handoff and NAT processing, Or same CPU with congestion
drop mechanism.*
*I studied the code and separate the CPUs of handoff and NAT processing, in
Fact that you can open vfio container doesn't actually mean that you can use
vfio-pci module on specific PCI device.
vfio-pci module can be used in 2 cases:
- when /sys/bus/pci/devices//iommu_group exists
- when /sys/module/vfio/parameters/enable_unsafe_noiommu_mode is set to Y
