[PATCH] ARM: dts: exynos: add cpu perf counters to Exynos54xx boards

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




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
