Original posting: http://lkml.kernel.org/r/[email protected] Several architectures have similar stack debugging config options. They all pretty much do the same thing, some with slightly differing help text. This patch changes the architectures to instead enable a Kconfig boolean, and then use that boolean in the generic Kconfig.debug to present the actual menu option. This removes a bunch of duplication and adds consistency across arches. Signed-off-by: Dave Hansen <[email protected]> Reviewed-by: H.

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.
