hid = "gpio-omap46x-GPIO1";
      compatible = {"ti,omap4-gpio"};
      regs = Res.mmio(0x4A310000, 0x4A310194); // This one is range of Address GPIO1 used
      irq = Res.irq(29); //This one is IRQ of GPIO1 ? What is the meaning of irq(29) ?
      scm_table = 0; // I still don't understand about this line
    end);
end);

And where can i read the reference about another parameters of this ? (Like there pins parameter in raspi b. And there are mems instead of regs)

2. I try the L4Re with x86 build run in QEMU. And want it to accept my keyboard input. So i need to include x86-legacy.devs module in modules.list and define REQUIRES_LIBS=libc_be_file_stdin isn't it ?

But after i've done it, it still doesn't accept keyboard input. what did i miss ?

I appreciate any answer and reference. And thanks for the answer
