- Re: how to get physical memory address from virtual memory address
Of course, you are wrong. Virtual addresses /only/ have corresponding physical addresses when they are used in a memory reference. Pure "allocation" (malloc()) doesn't result in a memory reference, so no real address is assigned. (FWIW, this is why the OOM killer works the way it does - it kills processes that have allocated memory- Re: how to get physical memory address from virtual memory address
Hari wrote: You have to do this in the kernel. Firstly, the page obviously has to be nailed down (unswappable). Otherwise it has no fixed physical address. When paged out, it has no address at all, and may get a different physical address each time it is paged out. You can do this using the get_user_pages() kernel function, which will- Re: how to get physical memory address from virtual memory address

In this show, Brian Madden has a conversation with Kevin Goodman, the architect and patent-holder of Citrix virtual memory optimization technology. Kevin will provide very detailed description of how this technology works, how you and test and manage it, and when it should and shouldnt be used.- Re: how to get physical memory address from virtual memory address
Unless of course the memory is swapped out at the moment, which is entirely possible after a fresh malloc() of a big chunk of memory. Correct- Memory management device and memory device
A memory management device for managing a nonvolatile semiconductor memory which comprises a plurality of blocks, and permits data to be erased in units of one block, the memory management device comprises a setting unit configured to set an address range of data to be erased in response to an...
