Subject: [PATCHv2 0/3] Add support to enable ARM PMU for EXYNOS4/5
Date: Fri, 27 Jul 2012 17:08:26 +0900 [thread overview]
Message-ID: <1343376509-5881-1-git-send-email-chanho61.park@samsung.com> (raw)
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
