Really? So what happens when the page is swapped out? It's still a valid virtual address, but there's no valid physical address behind it, until it's swapped back in by a page-fault or the prefetcher. -n- Flat cell read only memory using common contacts for bit lines and virtual ground lines
In a flat cell read only memory, two bit lines or two virtual ground lines share a common contact such that the contact is slightly adjustable in its location for inserting a local metal word line without increasing the layout area to improve the reading speed of the memory. Moreover,...- Re: how to get physical memory address from virtual memory address
Not true. When the respective page is swapped out, there is no physical address associated to given virtual address.- Re: how to get physical memory address from virtual memory address
Hi all, Thanks for the response from you all. My aim is to execute SDRAM diagnostics code to find which part of SDRAM chip is failed. So in code, I am using malloc to allocte available free memory and then locking the memory using mlock. I think once the mlock is done the pages what ever is allocted during malloc will be in the- 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
