From mboxrd@z Thu Jan 1 00:00:00 1970 From: dietmar.eggemann@arm.com (Dietmar Eggemann) Date: Thu, 8 Jun 2017 08:55:13 +0100 Subject: [PATCH 6/6] arm64: wire cpu-invariant accounting support up to the task scheduler In-Reply-To: <20170608075513.12475-1-dietmar.eggemann@arm.com> References: <20170608075513.12475-1-dietmar.eggemann@arm.com> Message-ID: <20170608075513.12475-7-dietmar.eggemann@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Commit 8cd5601c5060 ("sched/fair: Convert arch_scale_cpu_capacity() from weak function to #define") changed the wiring which now has to be done by associating arch_scale_cpu_capacity with the actual implementation provided by the architecture. Define arch_scale_cpu_capacity to use the arch_topology "driver" function topology_get_cpu_scale() for the task scheduler's cpu-invariant accounting instead of the default arch_scale_cpu_capacity() in kernel/sched/sched.h.
