| 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. | |
