This commit introduces SRD metrics through sysctl. The metrics can be queried using the following sysctl node: sysctl dev.ena..ena_srd_info Approved by: cperciva (mentor) MFC after: 2 weeks Sponsored by: Amazon, Inc. (cherry picked from commit 36d42c862f4a5643f6e2395e8d7b7e5c4580499a)

ena: Support customer metric with sysctl

2024-01-14T07:43:23Z

This commit adds sysctl support for customer metrics. Different customer metrics can be found in the following sysctl node: sysctl dev.ena..customer_metrics Approved by: cperciva (mentor) MFC after: 2 weeks Sponsored by: Amazon, Inc.

ena: Introduce shared sample interval for all stats

2024-01-14T07:43:23Z

Rename sample_interval node to stats_sample_interval and move it up in the sysctl tree to make it clear that it's relevant for all the stats and not only ENI metrics (Currently, sample interval node is found under eni_metrics node). Path to node: dev.ena..stats_sample_interval Once this parameter is set it will set the sample interval for all the stats node including SRD/customer metrics.

ena: Add sysctl support for spreading IRQs

2024-01-14T07:43:22Z

This commit allows spreading IO IRQs over different CPUs through sysctl. Two sysctl nodes are introduced: 1- base_cpu: servers as the first CPU to which the first IO IRQ will be bound. 2- cpu_stride: sets the distance between every two CPUs to which every two consecutive IO IRQs are bound. For example for doing the following IO IRQs / CPU binding: IRQ idx | CPU ---------------- 1 | 0 2 | 2 3 | 4 4 | 6 Run the following commands: sysctl dev.ena..irq_affinity.base_cpu=0 sysctl dev.ena..irq_affinity.cpu_stride=2 Also introduced rss_enabled field, which is intended to replace '#ifdef RSS' in multiple places, in order to prevent code duplication. We want to bind interrupts to CPUs in case of rss set OR in case the newly defined sysctl paremeter is set. This requires to remove a couple of '#ifdef RSS' as well in the structs, since we'll be using the relevant parameters in the CPU binding code.
