[dpdk-stable] patch 'test/power: add turbo mode to frequency check' has been queued to stable release 19.11.9

[Christian Ehrhardt]

Hi,

FYI, your patch has been queued to stable release 19.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/12/21. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/bad1135b3c27b62436d1f7c1e2463a0c1d60cba9

Thanks.

Subject: [PATCH] test/power: add turbo mode to frequency check

[ upstream commit 6db92b3b9bb130acf0bc9d774ab2d75ea67d00df ]

With the intel_pstate driver and turbo enabled, the top frequency in
the frequency array is the P1+1, i.e. 2300001, whereas the frequency
shown in scaling_cur_freq could be a lot higher.

This patch adds a flag to the check_cur_freq function so that we can
specify if a frequency is greater than expected (turbo mode), in which
case the check should be successful.

Fixes: aeaeaf5f2d62 ("test/power: add cases for turbo feature")
