It will be pushed if I get no objections before 02/26/22. 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/f05bbce1851d34a86ad6c1b7577916d8c8ae7dcf Thanks. Kevin --- >From f05bbce1851d34a86ad6c1b7577916d8c8ae7dcf Mon Sep 17 00:00:00 2001 From: Matan Azrad Date: Mon, 22 Nov 2021 15:12:35 +0200 Subject: [PATCH] vdpa/mlx5: workaround queue stop with traffic [ upstream commit b5e51edfbe18ee30b8fed5efdb09f2ab4c8a05a0 ] When the event thread polls traffic and a virtq is stopping, the FW loses synchronization in the virtq indexes. It causes LM failure on synchronization between the HOST indexes to the GUEST indexes. Unset the event thread before the queue stop in the LM process.
