affinity vsx 15600 r80.20

Hi

 

There are 32 CPU's without HT enabled on a 15600.

I have done the following with sim affinity -s:

eth3-01: CPU 2
eth3-02: CPU 5
eth3-03: CPU 6
eth3-04: CPU 0
eth1-01: CPU 1
eth2-01: CPU 3
eth2-02: CPU 4

And with fw ctl affinity -d -s -fwkall 25 I was hopping to get all VS to share CPU 7-31, but the outcome was the following:

VS_0 fwk: CPU 4 5 6 7 8 9 10 11 12 13 14 15 19 20 21 22 23 24 25 26 27 28 29 30 31
VS_1 fwk: CPU 4 5 6 7 8 9 10 11 12 13 14 15 19 20 21 22 23 24 25 26 27 28 29 30 31

So what happend with cpu 16-18 😞

MQ aint enabled, but I was thinking if MQ are enabled on onboard interfaces

cpmq get

Active mlx5_core interfaces:
eth2-01 [Off]
eth2-02 [Off]

Active ixgbe interfaces:
eth1-01 [Off]
eth3-01 [Off]
eth3-02 [Off]
eth3-03 [Off]
eth3-04 [Off]

 

What am I missing? 

I can ofcource manually set with fw ctl affinity -d -s -vsid and so on.. but then if I add a new VS I need to manually fix the affinity for that one.
