'Memory mapped files are read a page at a time and these pages are stored in the page cache. The page cache consists of the page_hash_table, a vector of pointers to mem_map_t data structures.' ... Reducing the size of the page and buffer caches: 'If the examined page is in the Linux page cache, it is removed from the page cache and freed. As none of the freed pages were part of any process's virtual memory (they were cached pages), then no page tables need updating' I've got 2 questions : 1 ) What kind of page or stored in the page cached : pages from executable images only, or also data from disk ? 2 ) When a file is memory mapped from disk, are all of its pages automatically stored in the page cache ? 3 ) When in cache, are they duplicated in physical memory and in page cache memory or do they stand only in one place and are referenced twice (both in the page_hash_table with mem_map_t and in the table page entry) ? Actually, what I try to understand the linux page cache management. That will make sense for me is the following procedure : - a process demand a file which is on disk - It is memory mapped into physical memory - the page tables entries are updated with the file's pages - after being used and not demanded for a (quite) long time they are referenced by the page cached in the page_hash_table, but no more in the page table (no entries in it). And therefore they keep their fisrt memory location. Am I wrong ?? Could you please give me a concrete example of what's happening in the page cache when we run a process ? Thanks for any help. ===== Sabrina 04-92-11-41-78 06-84-80-95-51 ___________________________________________________________ Do You Yahoo!? Achetez, vendez! À votre prix!

I agree with you, I didn't express myself correctly. What I wanted to say is : when an image is executed, the content of the executable image is brought into processes virtual address space. The executable file is not brought into physical memory, it is merely linked into the processes virtual memory : that is memory mapping. When a process accesses a virtual address of this executable processes virtual memory, if this virtual address does not have a valid page table entry, the processor report a page fault to linux. A nopage operation is used => linux bring into physical memory the required image page. If the required image page is not in the swap file, linux uses the page cache and check if it's in it. If it is in none of them, it takes it from the disk. (Am I right when I'm saying all of that ?). Then the image page is in physical memory but is it yet referenced in the page cache or will it be later ? How does the page cache work ? Are all pages brought into memory automatically referenced into the page cache ? > The page cache memory _is_ physical memory (caching > in > swap somehow doesn't make that much sense)... Yes of course but I didn't know how to differentiate pages in referenced by table page and pages referenced by page cache. ===== Sabrina 04-92-11-41-78 06-84-80-95-51 ___________________________________________________________ Do You Yahoo!?
