Most development boards and devices have one or more LEDs. It is useful during debugging if they can be wired to show different behaviours such as disk or cpu activity or a load-average dependent heartbeat. Enable panic and disk activity triggers so they can be tied to LED activity during debugging as well.
There was a similar patch which added these triggers for ARM64 as well: https://patchwork.kernel.org/patch/10042681/ Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasi...@linaro.org> --- arch/arm/configs/multi_v7_defconfig | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/arm/configs/multi_v7_defconfig b/arch/arm/configs/multi_v7_defconfig index 2e9fa5312616..466ccc305a05 100644 --- a/arch/arm/configs/multi_v7_defconfig +++ b/arch/arm/configs/multi_v7_defconfig @@ -821,6 +821,8 @@ CONFIG_LEDS_TRIGGER_GPIO=y CONFIG_LEDS_TRIGGER_DEFAULT_ON=y CONFIG_LEDS_TRIGGER_TRANSIENT=y CONFIG_LEDS_TRIGGER_CAMERA=y +CONFIG_LEDS_TRIGGER_PANIC=y +CONFIG_LEDS_TRIGGER_DISK=y CONFIG_EDAC=y CONFIG_EDAC_HIGHBANK_MC=y CONFIG_EDAC_HIGHBANK_L2=y -- 2.17.1
