2g/2g split

2g/2g split

[mike mike]

Hi,
  I am looking for some instructions as to how to do a '2g/2g', '1g/3g' 
splits (user/kernel space memory) on a linux system with a 2.4 based kernel.

  Thanks in advance.

M

You choose it in the configurator.

Thanks for the reply.

I did a "make xconfig", after extracting the source.  I don't see any place 
to enable this setting. Is that what I'm supposed to do, or something else ?

Many thanks.

Right. You can't see such things because it isn't in the mainline kernel ;)

You have to patch that feature in. Try this I've posted some days ago:

With the latest 2.6 tree, all you need to do to get a 2g/2g split is
change the two definitions of __PAGE_OFFSET in asm-i386/page.h from
0xC0000000 to 0x80000000.
