Saeed Mahameed says: ==================== mlx5-next: updates 2022-06-14 1) Updated HW bits and definitions for upcoming features 1.1) vport debug counters 1.2) flow meter 1.3) Execute ASO action for flow entry 1.4) enhanced CQE compression 2) Add ICM header-modify-pattern RDMA API Leon Says ========= SW steering manipulates packet's header using "modifying header" actions. Many of these actions do the same operation, but use different data each time. Currently we create and keep every one of these actions, which use expensive and limited resources. Now we introduce a new mechanism - pattern and argument, which splits a modifying action into two parts: 1. action pattern: contains the operations to be applied on packet's header, mainly set/add/copy of fields in the packet 2. action data/argument: contains the data to be used by each operation in the pattern. This way we reuse same patterns with different arguments to create new modifying actions, and since many actions share the same operations, we end up creating a small number of patterns that we keep in a dedicated cache. These modify header patterns are implemented as new type of ICM memory, so the following kernel patch series add the support for this new ICM type. ========== * 'mlx5-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux: net/mlx5: Add bits and fields to support enhanced CQE compression net/mlx5: Remove not used MLX5_CAP_BITS_RW_MASK net/mlx5: group fdb cleanup to single function net/mlx5: Add support EXECUTE_ASO action for flow entry net/mlx5: Add HW definitions of vport debug counters net/mlx5: Add IFC bits and enums for flow meter RDMA/mlx5: Support handling of modify-header pattern ICM area net/mlx5: Manage ICM of type modify-header pattern net/mlx5: Introduce header-modify-pattern ICM properties ==================== Link: https://lore.kernel.org/r/20220614184028.51548-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
