![]() ![]() In my humble opinion, this mechanism is useless nowadays because In order to limit segmentation fault management, buffers are allocated by big block (typically 1/4th of the max size). And therefore the memory will be allocated. The handler will enable permission access. A write to the buffer will trigger a segmentation fault that it will be caught by a dedicated handler. However memories can't be accessed (no read, no write permission). During the init, contiguous virtual memories are reserved to hold the various buffers. Recompiler buffers are lazy-allocated to reduce the physical memory footprint.
