Hi Chris,
No plan for open sourcing yet. One reason is nobody is developing P4 programs
for new VPP plugin nor is there any good online repo with great networking P4
programs. So, who would use the open-source compiler? The other reason is, I
would like to complete the UPF VPP product firs
Hi Hemant,
Do you plan to open source and maintain this code generator?

Hi Florin,
I am running in gdb only.
last few lines in gdb:

Try running vpp from gdb or, as previously recommended, try upgrading to latest

Hi Florin,
I am not seeing even backtrace. bt is just empty now. Also I have just added
session { } with empty params and seeing same exit.
No clues at vpp. is there any params that I need to add along with session so
that it does not exit?

Hi Sastry,
Can’t do much without a backtrace. Also, not entirely sure how vcl got a reply
if vpp crashed.
Session layer is the main component of the host stack that keeps track of
external apps and facilitates the exchange of data and notifications between
apps (like vcl) and transports. So
Hi Florin,
I tried to add session layer at vpp as below:
session {
session-baseva 0x20
evt_qs_memfd_seg
event-queue-length 10
}
vpp is still crashing and not able to run vpp. Also, is session layer important
for VCL application to run?

Hi Sastry,
As a first step, since you’ve just started development, I’d switch to vpp
latest to get recent features and fixes.
Regarding the issue you’re hitting, in older releases you had to explicitly
request memfd type of segment for the event queues (evt_qs_memfd_seg). Recently
that has b
Hi Florin,
My VPP version is 20.05 fdio.
I am suspecting seg_type why its not selecting SMH.
Also, startup.conf does not have session stuff:
session {
evt_qs_memfd_seg
event-queue-length 10
}
when I add these, vpp is crashing.
With Regards

Hi Matt, Ole, Nathan,
Matt,
I have no objection to the feature, I would just ask that you provide a
startup.conf option to disable it and an api to query that state. The
reason I say this is that there are configuration models that depend on the

While the process is in place to minimize the unnecessary pains, we

Hi Matt, Hi Ole,
I think adding a cli & api call for renaming interfaces would be quite
useful.
I agree we shouldn't refer to interfaces by name in the API thought
(sw_if_index is definitely the way to go)
Several non-api use-cases would imho benefit from this. I can see writing
