Subject: [PATCH v3 0/6] RT Capacity Awareness Fixes & Improvements
Date: Mon, 2 Mar 2020 13:27:15 +0000 [thread overview]
Message-ID: <20200302132721.8353-1-qais.yousef@arm.com> (raw)
Changes since v2:
* Fix missing check target != -1 (patch 2)
* Drop the logic to check for fit cpu in wakeup and switched_to_rt()
(patch 5)
* Added the patch that fixes pushing unfit cpu in select_task_rq_rt
That was patch 3 in v1[1] (patch 6)
Link to v2:
https://lore.kernel.org/lkml/20200223184001.14248-1-qais.yousef@arm.com/#t
Pavan, Steve and Dietmar pointed out a few issues and improvements that could
be done to the logic of RT Capacity Awareness, that this series fixes.
Please consider applying as fixes for 5.6.
Except for patch 6 which I'm not sure if the discussion around it has settled,
patches 1-5 should be good to go.
Thanks!
