2024-04-22net/mlx5e: Support updating coalescing configuration without resetting channelsRahul Rameshbabu
When CQE mode or DIM state is changed, gracefully reconfigure channels to handle new configuration. Previously, would create new channels that would reflect the changes rather than update the original channels. Co-developed-by: Nabil S. Alramli <dev@nalramli.com> Signed-off-by: Nabil S.

2024-04-22net/mlx5e: Dynamically allocate DIM structure for SQs/RQsRahul Rameshbabu
Make it possible for the DIM structure to be torn down while an SQ or RQ is still active. Changing the CQ period mode is an example where the previous sampling done with the DIM structure would need to be invalidated. Co-developed-by: Nabil S.

The first patch switches from a poll loop to read_poll_timeout. The second patch is a simple conversion to phylink because adjust_link won't work anymore. The third patch is preparation for future use. Using the "phy_interface_mode_is_rgmii" macro allows for the proper recognition of all RGMII modes.

Switch the delay loop during the Arbiter empty check from vsc73xx_adjust_link() to use read_poll_timeout(). Functionally, one msleep() call is eliminated at the end of the loop in the timeout case. As Russell King suggested: "This [change] avoids the issue that on the last iteration, the code reads the register, tests it, finds the condition that's being waiting for is false, _then_ waits and end up printing the error message - that last wait is rather useless, and as the arbiter state isn't checked after waiting, it could be that we had success during the last wait."

During module probe, regulator 'vin' and 'vdd-io' are used and enabled, but the vdd-io regulator overwrites the 'vin' regulator pointer. During remove, only the vdd-io is disabled, as the vin regulator pointer is not available anymore. When regulator_put() is called during resource cleanup a kernel warning is given, as the regulator is still enabled. Store the two regulators in separate pointers and disable both the regulators on module remove.

mv88e6250_phylink_get_caps() With the recent PHYLINK changes requiring supported_interfaces to be set, MV88E6250 family switches like the 88E6020 fail to probe - cmode is never initialized on these devices, so mv88e6250_phylink_get_caps() does not set any supported_interfaces flags. Instead of a cmode, on 88E6250 we have a read-only port mode value that encodes similar information. There is no reason to bother mapping port mode to the cmodes of other switch models; instead we introduce a mv88e6250_setup_supported_interfaces() that is called directly from mv88e6250_phylink_get_caps().

Due to performance reasons the number of layers of the scheduler tree is changing from 9 to 5. It requires a readjustment of these VSI/Aggregator layer values.

2024-04-22ice: Support 5 layer topologyRaj Victor
There is a performance issue when the number of VSIs are not multiple of 8. 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.

On older (pre-MLD API) devices, we started also calling iwl_mvm_set_link_mapping()/iwl_mvm_unset_link_mapping(), but of course not also iwl_mvm_remove_link(). Since the link ID was only released in iwl_mvm_remove_link() this causes us to run out of FW link IDs very quickly. Fix it by releasing the link ID correctly.

Additionally, this makes sure to punt to a workqueue before submitting preflushes - we really don't want to be calling submit_bio() in the main transaction commit path.
