Hi,
I am trying to figure out where VPP allocates memory for the DPDK TX queues.
In dpdk/common.c
I am seeing a call to: vec_validate_aligned (xd->tx_queues, xd->tx_q_used - 1,
CLIB_CACHE_LINE_BYTES)
I'm not if this allocates memory for each queue since I'm not seeing a size
other than for alig
Hi,
I've created a timestamp plugin to stamp all packets being received prior to
the ethernet-input node. The problem I'm seeing, based on debug prints I've
inserted into VLIB_NODE_FN (timestamp_node), is that my plugin node is running
way way after any other node (seconds). I have similar pr
Hi,
Has anyone figured this out?? I'm using 'make pkg-deb' and I'm similar results
as above. 'make run' and 'make debug' show my plugin, but it is not included
in the packages using 'make pkg-deb'
Thanks

If not, would adding a patch to time stamp the packets at ethernet-input as a
starting point make sense? What I am trying to do is collect the time it takes
for the packet to traverse VPP. I'm using this and placing it in the iOAM
telemetry data. The ending time stamp would then be somewhere in

Hi,
As stated in the title, I am wondering if VPP stamps every packet coming in and
right before it is TX'd out? If so, where can I find this in the code base?
Thanks,

Hi all,
I am trying to report the hardware interface queue depth. I'm looking at
ip6_forward and it seems that the process to TX a packet is vlib_get_next_frame
... [do things with packet] ... vlib_validate_buffer_enqueue ...
vlib_put_next_frame.
Before I go down this rabbit hole of code read
Thank you, I'm beginning to understand now, then total = available + cached +
used?
Is there a way to determine who has cached and who is using a specific buffer?
Is allocation of buffers bounded to a specific numa node? Or can they allocate
across numa nodes? If so, how is this determined?

Are there any resources where I can read more about the VPP buffer architecture?
@Dave
In regards to identifying the number of total buffers, are you referring to the
vector size of vlib_buffer_pools_t in vlib_buffer_main?
Thanks,
Mauricio

Hi,
I am looking to calculating the overall packet buffer occupancy. I've dug into
the buffer files and it looks like the main data structure holding buffer
information is "vlib_buffer_pool_t". This structure seems to take information
from the startup.conf "buffers {}" section. I'm confused
Justin,
I too am working on my master thesis, but I'm set to finish in December.
Currently, we're looking at video streaming and would like to get telemetry
data for buffer occupancy, queue depth, and transit delays. VPP seems the best
viable (and free) option for use.

Justin,
Do you know the release date for the updated iOAM plugin on the latest ietf
draft?
