It will be pushed if I get no objections before 02/28/23. 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/3d440ae7d319fb4d8d3b513058e6c76686f638fc Thanks. Kevin --- >From 3d440ae7d319fb4d8d3b513058e6c76686f638fc Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Thu, 16 Feb 2023 11:09:15 +0000 Subject: [PATCH] dma/ioat: fix indexes after restart [ upstream commit 79ab0f29dd9d734d0caf56e7694d7b0c6ead12e2 ] As part of the process of restarting a dma instance, the IOAT driver will reset the HW addresses and state values. The read and write indexes for SW use need to be similarly reset to keep HW and SW in sync.
