Anyone else snicker at the bit about page faults on page 8?
Apple is apparently now promoting the use of mmap:
> While this is a “solution”, it introduces the possibility of the user encountering page faults, which is an error/exception that occurs when the system is trying to access memory that is mapped into virtual memory but not actually loaded into RAM. This is something that, for the most part, has never existed on mobile devices.
- epistasis 11y ago"the possibility of the user encountering page faults" is absolutely hilarious. Clearly trying to take a stab at Apple because the author thinks that there should be more RAM in the boxes, and trying to come up with some justification without understanding that page faults are a basic and normal thing that happen all the time on any sort of modern device. Also, regarding the "never existed", check out this post from 2010 from John Carmack, discussing the challenges of dealing with iOS's mmap limitations at the time: http://www.bethblog.com/2010/10/29/john-carmack-discusses-rage-on-iphoneipadipod-touch/ http://www.bethblog.com/2010/10/29/john-carmack-discusses-ra...
- setpatchaddress 11y agoYes. That is a sad, sad paragraph. It reads like genuine ignorance on the part of the writer.
