| H A D | AbstractMemory.py | diff 9707:1305bec2733f Thu May 30 00:53:00 EDT 2013 Andreas Hansson <andreas.hansson@arm.com> mem: Avoid explicitly zeroing the memory backing store This patch removes the explicit memset as it is redundant and causes the simulator to touch the entire space, forcing the host system to allocate the pages. Anonymous pages are mapped on the first access, and the page-fault handler is responsible for zeroing them. Thus, the pages are still zeroed, but we avoid touching the entire allocated space which enables us to use much larger memory sizes as long as not all the memory is actually used. |
