2022-11-17ice: Add an option to pre-allocate memory for ice_sched_nodeMichal Wilczynski1-6/+17
devlink-rate API requires a priv object to be allocated when node still doesn't have a parent. This is problematic, because ice_sched_node can't be currently created without a parent. Add an option to pre-allocate memory for ice_sched_node struct. Add new arguments to ice_sched_add() and ice_sched_add_elems() that allow for pre-allocation of memory for ice_sched_node struct.

2022-11-17ice: Introduce new parameters in ice_sched_nodeMichal Wilczynski1-5/+76
To support new devlink-rate API ice_sched_node struct needs to store a number of additional parameters. This includes tx_max, tx_share, tx_weight, and tx_priority. Add new fields to ice_sched_node struct. Add new functions to configure the hardware with new parameters. Introduce new xarray to identify nodes uniquely.

Add infrastructure required for "ndo_setup_tc:qdisc_mqprio". ice_vsi_setup is modified to configure traffic classes based on mqprio data received from the stack. This includes low-level functions to configure min, max rate-limit parameters in hardware for traffic classes. Each traffic class gets mapped to a hardware channel (VSI) which can be individually configured with different bandwidth parameters.

2021-10-14ice: Fix failure to re-add LAN/RDMA Tx queuesBrett Creeley1-0/+13
Currently if the VSI is rebuilt/removed and the RDMA PF driver is active the RDMA Tx queue scheduler node configuration will not be cleaned up. This will cause the rebuild/re-add of the VSI to fail due to the software structures not being correctly cleaned up for the VSI index. Fix this by always calling ice_rm_vsi_rdma_cfg() for all VSI. If there are no RDMA scheduler nodes created, then there is no harm in calling ice_rm_vsi_rdma_cfg(). This change applies to all VSI types, so if RDMA support is added for other VSI types they will also get this change.

2020-07-29ice: distribute Tx queues evenlyVictor Raj1-4/+51
Distribute the Tx queues evenly across all queue groups. This will help the queues to get more equal sharing among the queues when all are in use. In the previous algorithm, the next queue group node will be picked up only after the previous one filled with max children. For example: if VSI is configured with 9 queues, the first 8 queues will be assigned to queue group 1 and the 9th queue will be assigned to queue group 2. The 2 queue groups split the bandwidth between them equally (50:50). The first queue group node will share the 50% bandwidth with all of its children (8 queues). And the second queue group node will share the entire 50% bandwidth with its only children. The new algorithm will fix this issue.

2019-06-28ice: Use struct_size() helperGustavo A. R. Silva1-2/+2
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; size = sizeof(struct foo) + count * sizeof(struct boo); instance = alloc(size, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: size = struct_size(instance, entry, count); This code was detected with the help of Coccinelle.

2019-04-18ice: Add code for DCB initialization part 3/4Anirudh Venkataramanan1-26/+1
This patch adds a new function ice_pf_dcb_cfg (and related helpers) which applies the DCB configuration obtained from the firmware. As part of this, VSIs/netdevs are updated with traffic class information. This patch requires a bit of a refactor of existing code. 1. For a MIB change event, the associated VSI is closed and brought up again. The gap between closing and opening the VSI can cause a race condition. Fix this by grabbing the rtnl_lock prior to closing the VSI and then only free it after re-opening the VSI during a MIB change event. 2. ice_sched_query_elem is used in ice_sched.c and with this patch, in ice_dcb.c as well. However, ice_dcb.c is not built when CONFIG_DCB is unset. This results in namespace warnings (ice_sched.o: Externally defined symbols with no external references) when CONFIG_DCB is unset. To avoid this move ice_sched_query_elem from ice_sched.c to ice_common.c.

2018-11-13ice: Remove node before releasing VSIAnirudh Venkataramanan1-1/+107
Before releasing the VSI, remove the VSI scheduler node. If not, the node is left in the scheduler tree and, on subsequent load, the scheduler tree contains the node so it does not set it in vsi_ctx. This, later, causes the node to not be found in ice_sched_get_free_qparent which leads to a "Failed to set LAN Tx queue context, error: -1". To remove the scheduler node, this patch introduces ice_rm_vsi_lan_cfg and related helpers.
