Re: [netmap] when does a packet in the netmap ring send out exactly

Hi, Netmap version (tag v11.3 vs master) should be unrelated. Are you using ixgbe? In this case it may depend on the ixgbe driver version that netmap is using for patching. On github master you can change the version by modifying the ixgbe line in LINUX/default-config.mak.in_. Valid versions are

Re: swaping ring slots between NIC ring and Host ring does not always success

Hi, Recently I found another problem with netmap. I think this new problem could be related to the problems in this threads so I just post the new problem here. In my setup, I have a sender program having a netmap ring (a pair of RX/TX ring) for the NIC and a ring for the host stack. The sender p

Re: local_unbound, resolvconf, vpn

Hi! Also I have to notice that there is another issue with the default local_unbound setup: by default unbound uses syslog for logging, but usually the local_unbound service starts before syslogd and so logging doesn't work until local_unbound will be reloaded. So it's looks reasonable to use log

Re: [netmap] when does a packet in the netmap ring send out exactly

Re: [netmap] when does a packet in the netmap ring send out exactly

Hi, I think if you call the TXSYNC ioctl without advancing the head pointer, then the tail is advanced as much as possible. Cheers luigi On Mon, Nov 20, 2017 at 3:35 PM, Xiaoye Sun wrote: > Hi, > > I found that the tail pointer only moves when the ring has less than half > of the slots available

Re: [netmap] when does a packet in the netmap ring send out exactly

Hi, I found that the tail pointer only moves when the ring has less than half of the slots available. This prevents me from knowing the accurate time when the packet in a slot is processed. Is there a way to move the tail pointer as long as the packet in the slot is processed? Is this a configurab
