It will be pushed if I get no objections before 03/06/22. 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 This queued commit can be viewed at: https://github.com/kevintraynor/dpdk-stable/commit/b254386fadae12b61245707e0a189dad7fa75447 Thanks. Kevin --- >From b254386fadae12b61245707e0a189dad7fa75447 Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Wed, 16 Feb 2022 16:06:08 +0000 Subject: [PATCH] dma/idxd: configure maximum batch size to high value [ upstream commit 6a87d036a7ced87ba39406032c42ec2749b2cb88 ] When configuring an Intel DSA instance using the utility script dpdk_idxd_cfg.py, explicitly set the max supported batch size value to a high value, to ensure large bursts are supported if so desired. The default in the linux kernel is now just 32 [1], which may not be sufficient for all DPDK apps.
