Hello I have a legacy application that we want to port to a MIPS (Cavium) architecture from a PPC based one. The board has 4GB memory of which we actually need almost 3GB in application space. On the PPC this is no issue since the split user/kernel is 3GB/1GB. We have to use the N32 ABI Initial tests on MIPS showed me the user-space limit of 2GB. We do not want to port the application to a 64bit Now the question is: are there any workarounds, tricks existing to get around this limitation? I found some mailthreads on this subject (n32-big ABI - http://gcc.gnu.org/ml/gcc/2011-02/msg00278.html, http://elinux.org/images/1/1f/New-tricks-mips-linux.pdf) but is looks like this is not accepted by the community. Is there any process planned or made in this area? Thanks --- Ronny
