Hi, I wrote a kernel module using a library that has its own memory manager. I have to pass an address and a size to this library. Til now I used vmalloc in init_module to prepare a big chunk of memory for library needs. But first I discovered that the max amount of vmalloc-able memory is 64 MB at a time. Ok I can allocate memory for library adding several chunks... That's the problem: vmalloc fails after a total ~112 MB on machines with 1 or 2 GB of RAM, while on a 256 MB machine the module allocates 128 MB so far. What are the limits of vmalloc? How can I allocate (for example) 256 MB of memory? I tried to use Rubini's allocator module, but the kernel 2.4.4 lacks of ioremap (or vremap) function needed to map physical himem address to a virtual address suitable by C code... Does anybody have tips or suggestion to solve this problem? Thanks to all, -------------------------------------------------------- Dott. Roberto Granato IP Networks Division RESI Informatica S.r.l.
