| Write kernel log output directly into the VGA buffer or to a serial |
| port. |
| |
| This is useful for kernel debugging when your machine crashes very |
| early before the console code is initialized. For normal operation |
| it is not recommended because it looks ugly and doesn't cooperate |
| with klogd/syslogd or the X server. You should normally N here, |
| unless you want to debug such a crash. |

| config 16KSTACKS |
| bool "Use 16Kb for kernel stacks instead of 8Kb" |
| help |
| If you say Y here the kernel will use a 16Kb stacksize for the |
| kernel stack attached to each process/thread. The default is 8K. |
| This increases the resident kernel footprint and will cause less |
| threads to run on the system and also increase the pressure |
| on the VM subsystem for higher order allocations. |
