WebMar 24, 2024 · Let’s look at the implementation of the mmap method. The core function is remap_pfn_range, which is used to create a mapping of actual physical addresses to vma virtual addresses. Webmmap () creates a new mapping in the virtual address space of the calling process. The starting address for the new mapping is specified in addr. The length argument specifies the length of the mapping (which must be greater than 0). If addr is NULL, then the kernel chooses the (page-aligned) address at which to create the mapping; this is the ...

WebMay 6, 2016 · The quality of determinism is, at it simplest, the guarantee that a process will work within a performance envelope. Because telco workloads are orchestrated in real-time and their traffic is processed in real-time, they need for each execution cycle to be the same as the previous one. WebMar 20, 2024 · Moving the majority of application data out of the heap and into mmapped files also trims down the structures needed to maintain that data. An operating system’s raw memory paging, which mmap leverages, may be limited to 4096 byte blocks, but it’s pretty efficient in managing those blocks.
