help
|
|
If you say Y here the kernel will use a 4Kb stacksize for the
|
|
kernel stack attached to each process/thread. This facilitates
|
|
running more threads on a system and also reduces the pressure
|
|
on the VM subsystem for higher order allocations. This option
|
|
will also use IRQ stacks to compensate for the reduced stackspace.

help
|
|
If you say Y here the kernel will use the Meta hardware trace
|
|
unit to output information about function entry and exit that
|
|
can be used by a debugger for profiling and call-graphs.

help
|

If you say Y here the kernel will write poison data to the
|
|
catch buffer registers on kernel entry. This will make any
|
|
problem with catch buffer handling much more apparent.
