Hi, This patches support pmu irq routed from CTI, such as implemented on OMAP4: - introduce some CTI helpers and registers' definition - introduce .enable_irq and .disable_irq into platform_data, so perf irq handler can handle irq correctly if it is routed from CTI on OMAP4 - configure CTI on OMAP4 so that perf can work on OMAP4 The patches have been tested Ok on Pandaboard, and 'perf' does work after applying them. v5: - build pmu device from hwmod - support runtime pm v4: - some minor fix(add __iomem, comments, checkpatch warning...) v3: - fix typo of patch 2/3 title, pointed by Will - move cti addresses to plat/omap44xx.h, suggested by Santosh Shilimkar v2: - move cti related code out of perf_event.c - introduce .enable_irq and .disable_irq into platform_data as suggested by Will. v1: - rebase the patch set against 2.6.38-rc6-next-20110301, fix conflicts, which is pointed out by Will Deacon arch/arm/include/asm/cti.h | 179 ++++++++++++++++++++++++++++ arch/arm/include/asm/pmu.h | 15 ++- arch/arm/kernel/perf_event.c | 20 +++- arch/arm/kernel/pmu.c | 12 ++- arch/arm/mach-omap2/devices.c | 126 +++++++++++++++++++- arch/arm/mach-omap2/omap_hwmod_44xx_data.c | 26 ++++ arch/arm/plat-omap/include/plat/omap44xx.h | 3 + 7 files changed, 367 insertions(+), 14 deletions(-) thanks, -- Lei Ming -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
