From mboxrd@z Thu Jan 1 00:00:00 1970 From: mihailescu2m@gmail.com (Marian Mihailescu) Date: Fri, 20 Oct 2017 22:39:12 +1030 Subject: [PATCH] ARM: dts: exynos: add cpu perf counters to Exynos54xx boards Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Hi, This patch enables support for ARM Performance Monitoring Units available in Cortex-A7 and Cortex-A15 CPU cores for Exynos54xx SoCs (5410, 5420 and 5422/5800). Exynos5410 currently has only Cortex-A7 nodes defined in the device tree, so the Cortex-A15 PMU is defined in the exynos5420 device tree file. Tested with perf on Odroid XU4 (Exynos5422): armv7_cortex_a7 PMU driver: 5 counters available armv7_cortex_a15 PMU driver: 7 counters available Regards, Marian -- Either I've been missing something or nothing has been going on.
