crypto: SW scheduler async crypto engine
Type: feature This patch adds new sw_scheduler async crypto engine. The engine transforms async frames info sync crypto ops and delegates them to active sync engines. With the patch it is possible to increase the single worker crypto throughput by offloading the crypto workload to multiple workers. By default all workers in the system will attend the crypto workload processing. However a worker's available cycles are limited. To avail more cycles to one worker to process other workload (e.g. the worker core that handles the RX/TX and IPSec stack processing), a useful cli command is added to remove itself (or add it back later) from the heavy crypto workload but only let other workers to process the crypto. The command is: - set sw_scheduler worker <idx> crypto <on|off> It also adds new interrupt mode to async crypto dispatch node. This mode signals the node when new frames are enqueued as opposed to polling mode that continuously calls dispatch node. New cli commands: - set crypto async dispatch [polling|interrupt] - show crypto async status (displays mode and nodes' states) Signed-off-by: PiotrX Kleski <piotrx.kleski@intel.com> Signed-off-by: DariuszX Kazimierski <dariuszx.kazimierski@intel.com> Reviewed-by: Fan Zhang <roy.fan.zhang@intel.com> Change-Id: I332655f347bb9e3bc9c64166e86e393e911bdb39
