WebDec 11, 2006 · The dynamic regions defined in the platform data will be appended to the `` mem[] `` array after the platform device resources, which implies that the total number of static and dynamic memory regions cannot exceed MAX_UIO_MAPS. The dynamic memory regions will be allocated when the UIO device file, /dev/uioX is opened. WebMemory mapped by mmap() is preserved across fork(2), with the same attributes. A file is mapped in multiples of the page size. For a file that is not a multiple of the page size, the remaining bytes in the partial page at the end of the mapping are zeroed when mapped, and modifications to that region are not written out to the file.

WebMemory-mapping is a mechanism that maps a portion of a file, or an entire file, on disk to a range of addresses within an application's address space. The application can then access files on disk in the same way it accesses dynamic memory. This makes file reads and writes faster in comparison with using functions such as fread and fwrite. WebThe High Memory is the segment of memory that user-space programs can address. It cannot touch Low Memory. Low Memory is the segment of memory that the Linux kernel can address directly. If the kernel must access High Memory, it has to map it into its own address space first.
