2023-02-07net/mlx5: Expose SF firmware pages counterMaher Sanalla1-0/+1
Currently, each core device has VF pages counter which stores number of fw pages used by its VFs and SFs. The current design led to a hang when performing firmware reset on DPU, where the DPU PFs stalled in sriov unload flow due to waiting on release of SFs pages instead of waiting on only VFs pages. Thus, Add a separate counter for SF firmware pages, which will prevent the stall scenario described above.

2023-01-10net/mlx5: Prevent high-rate FW commands from populating all slotsTariq Toukan1-0/+1
Certain connection-based device-offload protocols (like TLS) use per-connection HW objects to track the state, maintain the context, and perform the offload properly. Some of these objects are created, modified, and destroyed via FW commands. Under high connection rate, this type of FW commands might continuously populate all slots of the FW command interface and throttle it, while starving other critical control FW commands. Limit these throttle commands to using only up to a portion (half) of the FW command interface slots. FW commands maximal rate is not hit, and the same high rate is still reached when applying this limitation.

2022-12-08net/mlx5: fs, add match on ranges APIYevgeny Kliteynik1-0/+12
Range is a new flow destination type which allows matching on a range of values instead of matching on a specific value. Range flow destination has the following fields: - hit_ft: flow table to forward the traffic in case of hit - miss_ft: flow table to forward the traffic in case of miss - field: which packet characteristic to match on - min: minimal value for the selected field - max: maximal value for the selected field Note: - In order to match, the value in the packet should meet the following criteria: min <= value < max - Currently, the only supported field type is L2 packet length Signed-off-by: Yevgeny Kliteynik <[email protected]> Reviewed-by: Alex Vesker <[email protected]> Reviewed-by: Mark Bloch <[email protected]> Signed-off-by: Saeed Mahameed <[email protected]>

MLX5_UMR_KLM_ALIGNMENT is in units of number of entries, while MLX5_UMR_MTT_ALIGNMENT (generalized and renamed to MLX5_UMR_FLEX_ALIGNMENT) is in byte units. This is misleading and confusing.

2022-11-29net/mlx5e: Add padding when needed in UMR WQEsTariq Toukan1-0/+1
Per the device spec, MTTs/KLMs list in a UMR WQE must be aligned to 64B. Per our SW design, the MTT/KLMs list would need alignment only if it's too small, for example on PPC when PAGE_SIZE is 64KB, and only 4 pages are needed to cover a MPWQE of size 256KB. Padding, if needed, is taken into account when calculating the UMR WQE fields (ds_cnt and xlt_octowords), however no entries are provided, instead garbage is passed. No real harm though, as these parts act as gaps between the RX MPWQEs and not used by any of them. Hence, in practice, device does not try to write any incoming packet to them. Still, prefer providing clean padding marking the end of the list, and do not map garbage into the RQ memory region.
