27 prompt "Host memory split"
28 default HOST_VMSPLIT_3G
29 help
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'.
