CONFIG_4KSTACKS

Postby Ianb1972 » Wed Nov 02, 2005 12:27 pm

Can anyone tell me how disable and remove the 4K stack in Fedora 4 and install the 16K Stack?

I am new to this so if you can give me it easy steps!! lol

The reason I want to do this is when I type modprobe ndiswrapper when trying to install my wireless card is freezes the system

Many thanks
Ian

There is a config option in the "kernel hacking" section of the kernels config ...


Use 4kb for kernel stacks instead of 8kb

CONFIG_4KSTACKS

Code: Select all
Use 4Kb for kernel stacks instead of 8Kb 4KSTACKS

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.


not sure if thats what your looking for, no clue about any sysctrl or other method of changing it on the fly.
