Subject: [PATCH v2 08/10] arm64: wire frequency-invariant accounting support up to the task scheduler
Date: Thu, 6 Jul 2017 10:49:46 +0100 [thread overview]
Message-ID: <20170706094948.8779-9-dietmar.eggemann@arm.com> (raw)
In-Reply-To: <20170706094948.8779-1-dietmar.eggemann@arm.com>
Commit dfbca41f3479 ("sched: Optimize freq invariant accounting")
changed the wiring which now has to be done by associating
arch_scale_freq_capacity with the actual implementation provided
by the architecture.
Define arch_scale_freq_capacity to use the arch_topology "driver"
function topology_get_freq_scale() for the task scheduler's
frequency-invariant accounting instead of the default
arch_scale_freq_capacity() in kernel/sched/sched.h.
