Hmm, in both 2.6.9-bs7 and 2.6.11 the limit is at least 768M, and it extends to more than 2G with static linking and without TT mode. This is all without HIGHMEM support.
Retest also with 2.6.11, it feels a better tree than 2.6.9-bs7. What's the problem anyway? > What is the 2G/2G address space split?

Probably not interesting for you, it's just a disadvantage for UML, the option was just to cope with that situation (which is completely UML-independent). That gives faster access to upto 2G of physical RAM, by reducing the virtual address space for apps to only 2G rather than 3G. > I could not find any HIGHMEM support style things in configs anymore. That depends on ! CONFIG_CLEAN_COMPILE, so its disappears unless you disable CONFIG_CLEAN_COMPILE... it should compile well in 2.6.11, I don't remember for 2.6.9-bs7. > TIA, > -- Naked -- Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
