Hi, I've got a (simulated) system where I can select my cache sizes. Boot goes fine with 4, 8, and 16k cache, but goes boink with 32k cache. While debugging, I'm able to find out that in __do_page_fault, I end up at the label out_of_memory, as handle_mm_fault returns VM_FAULT_OOM.
This does not happen with caches <32k. Otherwise, both my system and my linux config are identical, only the cache size is different. Is there anything that can explain this ? Do I need to modify the kernel configuration somehow if I want to use 32k caches ? Does the kernel consume more memory when using 32k caches due to dealing with cache coloring ? In short, any easy answers ?
