This patchset fixes irq numbers of ARM Performance Monitoring unit and enable it for Perf(Performance Counter) on the exynos 4 and 5. The exynos4 and 5 have 2 more cpu cores which has its own pmu. The exynos uses combiner-irq type for arm-pmu. Especially, the exynos4412 has 4 extra combined irq groups. So, we need to change a max combiner number and to retreive it according to each soc types. To enable perf, we need also to implement a set_irq_affinity function for the combiner-irq. After applying this patch, we can use the perf for the exynos machine. Changes from v3: - Define max_combiner_nr according to soc types - Add armpmu dt binding for exynos4210 - Clean up soc types comparison from v2 Changes from v2: - Convert to dt binding of exynos5250 Changes from v1: - Split arm-pmu init of exynos from plat-samsung - Correct combined irqs of exynos4412 - Use soc_is_xxx function instead of CONFIG_XXX to identify dynamically Chanho Park (5): ARM: EXYNOS: Add set_irq_affinity function for combiner_irq ARM: EXYNOS: Correct combined IRQs for exynos4 ARM: EXYNOS: Enable PMUs for exynos4 ARM: EXYNOS: Add arm-pmu DT binding for exynos5250 ARM: EXYNOS: Add arm-pmu DT binding for exynos421x arch/arm/boot/dts/exynos4210.dtsi | 6 ++ arch/arm/boot/dts/exynos5250.dtsi | 6 ++ arch/arm/mach-exynos/common.c | 100 ++++++++++++++++++++++++++---- arch/arm/mach-exynos/include/mach/irqs.h | 12 +++- arch/arm/plat-samsung/devs.c | 2 +- 5 files changed, 111 insertions(+), 15 deletions(-) -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
