It will be pushed if I get no objections before 05/20/19. So please shout if anyone has objections. Also note that after the patch there's a diff of the upstream commit vs the patch applied to the branch. This will indicate if there was any rebasing needed to apply to the stable branch. If there were code changes for rebasing (ie: not only metadata diffs), please double check that the rebase was correctly done. Queued patches are on a temporary branch at: https://github.com/kevintraynor/dpdk-stable-queue This queued commit can be viewed at: https://github.com/kevintraynor/dpdk-stable-queue/commit/897b241d2d5baaf6de15133608b573da241d8e4e Thanks. Kevin Traynor --- >From 897b241d2d5baaf6de15133608b573da241d8e4e Mon Sep 17 00:00:00 2001 From: Nikhil Rao Date: Fri, 10 May 2019 13:38:10 +0530 Subject: [PATCH] eventdev: fix Rx adapter event flush MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ upstream commit 339677f87023ccfa8d96b88dd4469a0dc25f813d ] The Rx adapter flushes events only if it has BATCH_SIZE events buffered where BATCH_SIZE is set to 32, e.g., if a single packet is sent, it is never passed to eventdev. Fix this issue by adding an event buffer flush either when a Rx queue is found to be empty or the adapter service function has processed the max number of packets for an invocation.
