Can I rearrange dll images in my .NET app's address space to make more contiguous free space available?
This image shows fragmentation in my app's address space. Is there any way to force the (third-party) dll images (purple) together to eliminate (or mitigate) the fragmentation? This app will run on 32-bit XP; obviously when we eventually move to 64-bit Windows 7, this problem will go away. Thanks! ...
How does memory protection in SASOS works?
I'd like to know how it works - whether it checks if process can read/write/execute memory on every access, or it does it only once? But when it does it only once, and all processes are in a single address space, how are these other hostile processes are prevented from accessing memory from not their's areas? How is it solved in Mungi OS...
Why can't OS use entire 64-bits for addressing? Why only the 48-bits?
I'm reading "Understanding Linux Kernel". Paging for 64-bit Architectures As we have seen in the previous sections, two-level paging is commonly used by 32-bit microprocessors. Two-level paging, however, is not suitable for computers that adopt a 64-bit architecture. Let's use a thought experiment to explain why: ...
