| 30 | This is needed when the host kernel on which you run has a non-default | ||
| 31 | (like 2G/2G) memory split, instead of the customary 3G/1G. If you did | ||
| 32 | not recompile your own kernel but use the default distro's one, you can | ||
| 33 | safely accept the "Default split" option. | ||
| 34 | |||
| 35 | It can be enabled on recent (>=2.6.16-rc2) vanilla kernels via | ||
| 36 | CONFIG_VM_SPLIT_*, or on previous kernels with special patches (-ck | ||
| 37 | patchset by Con Kolivas, or other ones) - option names match closely the | ||
| 38 | host CONFIG_VM_SPLIT_* ones. | ||
| 39 | |||
| 40 | A lower setting (where 1G/3G is lowest and 3G/1G is higher) will | ||
| 41 | tolerate even more "normal" host kernels, but an higher setting will be | ||
| 42 | stricter. | ||
| 43 | |||
| 44 | So, if you do not know what to do here, say 'Default split'. | ||
