| znf | Does anyone have experience with Mellanox cards under Ubuntu 22.04? The "old" driver under 18.04 allowed me to change the number of rings/queues with `ethtool -L enp94s0f0np0 combined X`, which would reduce the number of IRQs in use by the card. On 22.04's "newer" driver, ethtool -L doesn't seem to have any effect, no matter what I pass, the card will still use 63 queues, which is sort of a problem because I only have 20 cores/40 threads in total, | 17:24 |
|---|---|---|
| znf | so set_irq_affinity would assign more than 1 IRQ to some CPU cores | 17:24 |
| znf | My question would be - is this an issue/regression in the latest drivers, or am I doing something wrong the non-mellanox way? | 17:25 |
