关闭qcom soc系列手机的ramdump mode

在 kernel/msm-3.10 / arch/arm64/configs/ze550kl_user_defconfig中

将CONFIG_MSM_DLOAD_MODE=y改成

#CONFIG_MSM_DLOAD_MODE is not set

然后在/ drivers/power/reset/msm-poweroff.c中将

if (!in_panic) {
// Normal reboot. Clean the printk buffer magic
printk_buffer_slot2_addr = (ulong *)PRINTK_BUFFER_SLOT2;
*printk_buffer_slot2_addr = 0;
}

改成

#ifdef CONFIG_MSM_DLOAD_MODE
if (!in_panic) {
// Normal reboot. Clean the printk buffer magic
printk_buffer_slot2_addr = (ulong *)PRINTK_BUFFER_SLOT2;
*printk_buffer_slot2_addr = 0;
}
#endif
