 |
|
Maybe I'm confused, but I really don't want EARLY_PRINTK enabled, but I can't turn it off in gentoo-sources-2.6.29-r5.
The long trail of info at bootup is really dull compared to the wizbang of natural_gentoo and I want the info off. It feels like EARLY_PRINTK needs to be disabled, but make menuconfig will not let me disable, as if it were required for something.
But I can't find anything that enables it or depends on it.
Does anyone have any ideas?
Thanks,
Brian

I found it in
| Quote: | | ./arch/x86/Kconfig.debug:33:config EARLY_PRINTK |
menu: "kernel hacking"
defaults to yes -- silly wrt what the comment tells you 
shows up only if you build an EMBEDDED system -- wtf?!
the default config to edit
| Quote: | ./arch/x86/configs/i386_defconfig:2095:CONFIG_EARLY_PRINTK=y
./arch/x86/configs/x86_64_defconfig:2064:CONFIG_EARLY_PRINTK=y |
found by command: die@ana:/usr/src/linux $ find -type f -exec grep -Hn EARLY_PRINTK {} +

Thanks. I found it there too. But if I change it to "n" and re-run make menuconfig, it turns it back on.
Something is requiring it, but I don't know what. I even looked for depends and config, but that didn't show anything requiring it, except MIPS stuff.
Any ideas?
Brian

I set default to n in arch/x86/Kconfig.debug and it is disabled then. (x86_64 arch here)

Thanks much! That did it!
Now to see if the boot is prettier.

It worked, but there's still reams of info coming from the kernel at boot time.
Oh well.

EMBEDDED doesn't actually make an embedded system - it just lets you toggle switches that should only be necessary to change for embedded systems. So, set that to yes, then go into the submenu and toggle early printk,

| hm, if i activate EMBEDDED in the kernel (although it is not recommended as said in the help), i can set EARLY_PRINTK to off. so is it recommended to turn EMBEDDED on? |

| Dude, just append "quiet" to your kernel boot parameters. |
