	Type: improvement Previously multiple sw crypto scheduler queues per core design caused unaverage frame processing rate for each async op ID – the lower the op ID is the highly likely they are processed first. For example, when a RX core is feeding both encryption and decryption jobs of the same crypto algorithm to the queues at a high rate, in the mean time the crypto cores have no enough cycles to process all: the jobs in the decryption queue are less likely being processed, causing packet drop. To improve the situation this patch makes every core only owning a two queues, one for encrypt operations and one for decrypt. The queue is changed either after checking each core or after founding a frame to process. All crypto jobs with different algorithm are pushed to thoses queues and are treated evenly. In addition, the crypto async infra now uses unified dequeue handler, one per engine. Only the active engine will be registered its dequeue handler in crypto main.

2020-09-03	crypto: SW scheduler async crypto engine	PiotrX Kleski	1	-0/+61
	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
