Re: [vpp-dev] Query regarding CLI handling

2018-10-03 Thread abbas ali chezgi via Lists.Fd.Io

 
hi Damjan,vppsb router plugin used routing table manipulation APIs. is it 
needed to do lock in this operations?this functions called when netlink message 
arrived.
used APIs:    fib_table_entry_deletefib_table_entry_path_remove2
 fib_table_entry_updatefib_table_entry_path_add2

is there any documents for safe manipulation of fib tables from plugins?
thanks.

Hi  In one of our VPP plugin,  we have CLI’s which is used to display some info 
and this is time consuming.Thus the main thread, which is busy doing the above, 
cannot interact with the control plane which interacts with the main thread 
over the shared memory interface for this duration.Does VPP support offloading 
the CLI handling to a thread other than the main thread ?

Easiest way to address this is to periodically suspend your calculation by 
using vlib_process_suspend()that will give chance to other process nodes to do 
some work.
Also, please note that all debug CLIs by default are considered thread unsafe, 
which means that workerthreads are stopped during their execution and that 
typically happens for few hundred microseconds.After making your CLI handler 
thread safe, you can specify:
VLIB_CLI_COMMAND (foo_cli_command, static) = {[snip] .is_mp_safe = 1;};
Similar applies to API handlers...

Hello Dave, if you change the nsim delay values on the fly it appears vpp 
crashes and all the state is lost.



Is this supported?  Should I file a bug?

If so what logs should I attach?

Unfortunately this is our reality, and I don't expect things to be better 
unless we decide to decouple code verification form the distro packaging

> Is that drop visible in CSIT trending graphs?

Mostly not, apparently it depends (at least)
on NIC (x520 is not affected)
and on number of CPU cores for workers (visible for 4).

The biggest drop I see is here [0].

Hi All,
 In our recent test, I found a performance drop in master branch. I 
execute the l2bd test case in a 2.5GHZ CPU and found almost 35% drop compared 
to 18.07 release. My test is set two NIC ports to a same bridge domain and send 
traffic to test the l2 forward performance. I found in the master branch, 
l2flood function consume much more CPU cycles than 18.07 which means any test 
use the l2flood function will also have a performance drop. Can anybody kindly 
help to check this issue? Thanks a lot.

Regards,
Yuwei


Is that drop visible in CSIT trending graphs?

Re: [vpp-dev] WRED

2018-10-03 Thread Dave Barach via Lists.Fd.Io

Please send a backtrace. Here are some general bug reporting suggestions: 
https://wiki.fd.io/view/VPP/BugReports.

I’ve certainly reconfigured the simulator with traffic flowing without having 
the wheels fall off, but the code is brand-new.

Thanks... Dave

Hello Dave, if you change the nsim delay values on the fly it appears vpp 
crashes and all the state is lost.

Is this supported?  Should I file a bug?
If so what logs should I attach?

Re: [vpp-dev] "Incompatible UPT version” error when running VPP v18.01 with DPDK v17.11 on VMWare with VMXNET3 interface ,ESXI Version 6.5/6.7

2018-10-03 Thread chetan bhasin

Hi,

We also faced the same issue . If you set "nopku" in grub , this solves our
problem. Although we need to see what its impact.

Thanks,
Chetan Bhasin

Easiest way to address this is to periodically suspend your calculation by 
using vlib_process_suspend()
that will give chance to other process nodes to do some work.

Also, please note that all debug CLIs by default are considered thread unsafe, 
which means that worker
threads are stopped during their execution and that typically happens for few 
hundred microseconds.
After making your CLI handler thread safe, you can specify:

VLIB_CLI_COMMAND (foo_cli_command, static) = {
[snip]
 .is_mp_safe = 1;
};

Similar applies to API handlers...

[vpp-dev] VAT api changes 5507192..8807674

2018-10-03 Thread Peter Mikus via Lists.Fd.Io

Hello devs,

Recently in CSIT we are facing the issue with vpp_api_test console with JSON 
enabled, when calling dump_interface_table:

dump_interface_table:6017: JSON output supported only for VPE API calls and 
dump_stats_table
main:427: BUG: message reply spin-wait timeout

our API call:

$ sudo -S vpp_api_test json in dump_interfaces.vat script

Where:
$ cat dump_interfaces.vat
sw_interface_dump
dump_interface_table
quit

Brief bisecting reveals that its happening after one of these:

$ git log --pretty=oneline 5507192..8807674
88076749e663e35925c2212eb79e2ec4ce023772 (HEAD -> master, origin/master,

Could you please take a look and let us know if this is bug or desired?

Thank you.

[vpp-dev] Query regarding CLI handling

2018-10-03 Thread Alok Makhariya

Hi

In one of our VPP plugin,  we have CLI's which is used to display some info and 
this is time consuming.
Thus the main thread, which is busy doing the above, cannot interact with the 
control plane which interacts with the main thread over the shared memory 
interface for this duration.
Does VPP support offloading the CLI handling to a thread other than the main 
thread ?

Thanks
Alok
