9 | Write kernel log output directly into the VGA buffer or to a serial | |
10 | port. | |

12 | This is useful for kernel debugging when your machine crashes very | |
13 | early before the console code is initialized. For normal operation | |
14 | it is not recommended because it looks ugly and doesn't cooperate | |
15 | with klogd/syslogd or the X server. You should normally N here, | |
16 | unless you want to debug such a crash. | |

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