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 use 2 more cpu core which has its own pmu. We should define pmu irq numbers according to the number of cpus. The pmu irq of exynos4 and 5 uses combiner-irq type. The exynos4412 especially has 4 extra combined irq groups. We should enable the groups beacuse two pmu irqs are there. To enable perf, we need also to implement a set_irq_affinity function about the combiner-irq. After this patch, we can use the perf for the exynos machine. 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 (3): ARM: EXYNOS: Add set_irq_affinity function for combiner_irq ARM: EXYNOS: Correct combined IRQs for exynos4412 ARM: EXYNOS: Enable PMUs for exynos4/5 arch/arm/mach-exynos/common.c | 137 +++++++++++++++++++++++++++--- arch/arm/mach-exynos/include/mach/irqs.h | 11 ++- arch/arm/plat-samsung/devs.c | 3 +- 3 files changed, 135 insertions(+), 16 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
