Most of the time spent on adding new flow steering rule is executing the firmware command. The most common action is adding a new flow steering entry. In order to enhance the update rate we parallelize the commands by doing the following: 1) Replace the mutex lock with readers-writers semaphore and take the write lock only when necessary (e.g. allocating a new flow table entry index or adding a node to the parent's children list). When we try to find a suitable child in the parent's children list (e.g. search for flow group with the same match_criteria of the rule) then we only take the read lock. 2) Add versioning mechanism - each steering entity (FT, FG, FTE, DST) will have an incremental version. The version is increased when the entity is changed (e.g. when a new FTE was added to FG - the FG's version is increased). Versioning is used in order to determine if the last traverse of an entity's children is valid or a rescan under write lock is required. This support improves the insertion rate of steering rules from ~5k/sec to ~40k/sec. Signed-off-by: Maor Gottlieb <maorg@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
