Estou usando o Ubuntu 14.0 para o sistema operacional.
Minha imagem é construída com o Yocto Project e usando o i.MX6 sabreSD como meu processador.
Aqui está o problema agora.
No meu sistema eu terei o comando "poweroff" para desligar minha máquina.
Mas agora estou tentando mudar o comando, quando eu executo o comando "poweroff" no sistema eu preciso que ele entre no modo sleep.
Este é o log quando eu executo o poweroff agora.

Eu tinha tentado encontrar o arquivo no driver linux, quando ele desligou ele vai rodar nesse arquivo "kernel / reboot.c".
E descobri que funcionará abaixo da função.
void kernel_power_off(void)
{
kernel_shutdown_prepare(SYSTEM_POWER_OFF);
if (pm_power_off_prepare)
pm_power_off_prepare();
migrate_to_reboot_cpu();
syscore_shutdown();
pr_emerg("winmate victor Power down\n");
kmsg_dump(KMSG_DUMP_POWEROFF);
machine_power_off();
}
EXPORT_SYMBOL_GPL(kernel_power_off);
E se eu marcar o conteúdo em kernel_power_off, haverá kernel panic quando eu executar "poweroff".
Como posso alterar o desligamento para o modo de suspensão?
Obrigado em Avançado!
