something like that would be good. is there really anything PPC32
specific about it?
Apparently. The Kconfig option is only available for arch/powerpc and
arch/ppc, and the only place in the whole codetree where
CONFIG_TASK_SIZE is used is that particular spot in
Hi
I am trying to enable 1 GB of lowmem on a Freescale 8280.
In arch/ppc this was easilly done by:
CONFIG_ADVANCED_OPTIONS=y
CONFIG_HIGHMEM_START=0xfe00
CONFIG_LOWMEM_SIZE_BOOL=y
CONFIG_LOWMEM_SIZE=0x4000
CONFIG_KERNEL_START_BOOL=y
CONFIG_KERNEL_START=0xa000
This does not work in
=0xa000
This does not work in arch/powerpc. CPU hangs as soon as init starts.
Any ideas what to look at, what to change?
The reason I want to do this is because I cannot get highmem
support to
work when using CONFIG_PREEMPT_RT.

Scratch that. 1 GB lowmem works with vanilla 2.6.25.4, but
not at all with 2.6.25.4-rt[13]

Highmem still doesn't work.

We should really add some sanity check on CONFIG_TASK_SIZE vs
KERNEL_START.
Something like this?
