Subject: [PATCH 0/4] cpu/hotplug: rollback and "fail" interface fixes
Date: Mon, 11 Jan 2021 17:10:43 +0000 [thread overview]
Message-ID: <1610385047-92151-1-git-send-email-vincent.donnefort@arm.com> (raw)
From: Vincent Donnefort <vincent.donnefort@arm.com>
This patch-set intends mainly to fix HP rollback, which is currently broken,
due to an inconsistent "state" usage and an issue with CPUHP_AP_ONLINE_IDLE.
It also improves the "fail" interface, which can now be reset and will reject
CPUHP_BRINGUP_CPU, a step that can't always fail.
Vincent Donnefort (4):
cpu/hotplug: Allowing to reset fail injection
cpu/hotplug: CPUHP_BRINGUP_CPU exception in fail injection
cpu/hotplug: Add cpuhp_invoke_callback_range()
cpu/hotplug: Fix CPU down rollback
