Subject: [PATCH v3 0/2] make arm_cpuidle_suspend() a bit more efficient
Date: Thu, 31 Mar 2016 17:31:05 +0800 [thread overview]
Message-ID: <1459416667-307-1-git-send-email-jszhang@marvell.com> (raw)
There's one corner case need to be fixed: !cpuidle_ops[cpu].init.
patch1 tries to address this corner case.
patch2 tries to improve arm_cpuidle_suspend() a bit by moving .suspend
check into arm_cpuidle_read_ops().
Since v2:
- add back patch1.
Since v1:
- drop patch1, I.E "ARM: cpuidle: fix !cpuidle_ops[cpu].init case
during init", because there may be platforms which doesn't need the
init member at all.
- adopt Daniel's suggestion to move the cpuidle_ops.suspend check to
arm_cpuidle_read_ops().
