Hi,

FYI, your patch has been queued to stable release 20.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/11/22. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/a166f7044b9f1210546c7ca136604088ca4f8822

Thanks.

Luca Boccassi

Subject: [PATCH] app/compress-perf: fix cycle count operations allocation

[ upstream commit 81353ea4dc2a57d8c4378fda6e3e0e6b6db6cd21 ]

In cyclecount main_loop function, each iteration it tries to
enqueue X ops, in case Y<X ops were enqueued, the rest of the
X-Y ops are moved to the beginning of the ops array, to preserve
ops order, and next Y ops are allocated for the next enqueue
action, the allocation of the ops occurs on the first Y entries
in the array, when it should have skipped the first X-Y
array entries and allocate the following Y entries.

Fix the allocation by adding the correct offset.

Fixes: 2695db95a147 ("test/compress: add cycle-count mode to perf tool")
