From 0b275d32a4d7eaf420dcb8e0fcca50c079f6fecf Mon Sep 17 00:00:00 2001 From: Jerin Jacob Date: Thu, 18 May 2017 16:40:41 +0530 Subject: [PATCH] eventdev: clarify the worker thread workflow If the RTE_EVENT_DEV_CAP_DISTRIBUTED_SCHED capability flag is not set indicates the device is centralized and thus needs a dedicated scheduling thread that repeatedly calls rte_event_schedule(). Update the worker thread code snippet to match the description.
