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.

This option will cause messages to be printed if free stack space
|
||
|

drops below a certain limit.

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.
