Cannot control XL710 VF interrupte rate

Hi,

I'm doing the tuning job for XL710 VF on a FreeBSD10 VM (driver is ixlv-1.2.11) hosted on a kvm-hypervisor server (pf driver is i40e-1.4.25).

I found for each queue of the vf the interrupte rate is very high (>10000/sec).

As said in the datasheet, I tried to set I40E_VF_ITRN by the VF driver and set I40E_VPINT_RATEN by the PF driver. But this didn't work.

I have upgraded the NVM to 5.02 the latest version.

Could anybody help me resolve the issue?

Hi fishingbear2,

 

 

You may want to try the updated drivers found in this link - https://sourceforge.net/projects/e1000/files/

Thanks you Vince, but I'm using FreeBSD as VM OS. The lastest vf driver is 1.2.11 and the interrupt issue exists.

Hi JX,

 

 

Please try use the following command and feel free to update me the result>

 

 

Ethtool –c tx-usecs 125 rx-usecs 125, this should limit each queue to 8000 interrupts.

 

 

 

Thanks,
