From 95ad92d687e78c90e720174ffdf7a728add95b9e Mon Sep 17 00:00:00 2001 From: Steven Zou Date: Thu, 8 Feb 2024 11:18:37 +0800 Subject: ice: Add switch recipe reusing feature New E810 firmware supports the corresponding functionality, so the driver allows PFs to subscribe the same switch recipes. Then when the PF is done with a switch recipes, the PF can ask firmware to free that switch recipe. When users configure a rule to PFn into E810 switch component, if there is no existing recipe matching this rule's pattern, the driver will request firmware to allocate and return a new recipe resource for the rule by calling ice_add_sw_recipe() and ice_alloc_recipe(). If there is an existing recipe matching this rule's pattern with different key value, or this is a same second rule to PFm into switch component, the driver checks out this recipe by calling ice_find_recp(), the driver will tell firmware to share using this same recipe resource by calling ice_subscribable_recp_shared() and ice_subscribe_recipe(). When firmware detects that all subscribing PFs have freed the switch recipe, firmware will free the switch recipe so that it can be reused. This feature also fixes a problem where all switch recipes would eventually be exhausted because switch recipes could not be freed, as freeing a shared recipe could potentially break other PFs that were using it.

This is caused due to the max children limitation per node(8) in 9 layer topology. The BW credits are shared evenly among the children by default. Assume one node has 8 children and the other has 1. The parent of these nodes share the BW credit equally among them. Apparently this causes a problem for the first node which has 8 children. The 9th VM get more BW credits than the first 8 VMs. Example: 1) With 8 VM's: for x in 0 1 2 3 4 5 6 7; do taskset -c ${x} netperf -P0 -H 172.68.169.125 & sleep .1 ; done tx_queue_0_packets: 23283027 tx_queue_1_packets: 23292289 tx_queue_2_packets: 23276136 tx_queue_3_packets: 23279828 tx_queue_4_packets: 23279828 tx_queue_5_packets: 23279333 tx_queue_6_packets: 23277745 tx_queue_7_packets: 23279950 tx_queue_8_packets: 0 2) With 9 VM's: for x in 0 1 2 3 4 5 6 7 8; do taskset -c ${x} netperf -P0 -H 172.68.169.125 & sleep .1 ; done tx_queue_0_packets: 24163396 tx_queue_1_packets: 24164623 tx_queue_2_packets: 24163188 tx_queue_3_packets: 24163701 tx_queue_4_packets: 24163683 tx_queue_5_packets: 24164668 tx_queue_6_packets: 23327200 tx_queue_7_packets: 24163853 tx_queue_8_packets: 91101417 So on average queue 8 statistics show that 3.7 times more packets were send there than to the other queues. The FW starting with version 3.20, has increased the max number of children per node by reducing the number of layers from 9 to 5. Reflect this on driver side.
