This technique reveals the pool tag associated with the memory leak; the driver or component that uses this pool tag is responsible for the leak. 2018-01-02 · Kernel-memory-leaking Intel processor design flaw forces Linux, Windows redesign Speed hits loom, other OSes need fixes Chris Williams, Editor in Chief Tue 2 Jan 2018 // 19:29 UTC The Linux kernel uses node, zone, and page to describe physical memory. The partitions' buddy allocator focuses on a certain zone on a certain node. Before the 4.8 version, the Linux kernel implemented the page recycling strategy based on zone, because the early design was mainly for 32-bit processors, and there was a lot of high memory. For in-kernel compression to work, the kernel must take byte sequences in memory and compress them, and then keep the compressed version in RAM until some point in the future when the data is needed again. While the data is in a compressed state, it is impossible to read any individual bytes from it or write any individual bytes to it.

Referencing memory after it has been freed can cause a program to crash, use kernel memory by leveraging the absence of a certain orphaning operation.

2 Aug 2019 The Out-Of-Memory Killer is the process which is responsible for terminating the application to save the kernel from crashing.

The nonpaged kernel memory in task manager refers to the kernel memory that uses your RAM. Paged Kernel Memory. The kernel is a computer program at the core of a computer's operating system that has complete control over everything in the system. It is the "portion of the operating system code that is always resident in memory", and facilitates interactions between hardware and software components.

Kernel memory

17 Jan 2013 Fortunately for us, the linux kernel has ftrace which is a tracing framework that allows to trace general events, and in particular memory allocation 

Here is gonzo again: Linux processes are implemented in the kernel as instances of task_struct, the process descriptor.The mm field in task_struct points to the memory descriptor, mm_struct, which is an executive summary of a program's memory. In other words, the memory model must in some sense provide the least common denominator of the guarantees of all memory models of all CPU families that run the Linux kernel. This sort of "lower bound" on bad memory behavior is normally why people target C11 or C++11, but if the author's happen to see this comment I would recommend checking out the work of Karl Crary at CMU [2]. “Mini-dumps” and “small kernel dumps” are convenient for some purposes, but they usually don’t have enough info for finding the root cause of a kernel driver problem. It’s easy to set up your system to get kernel memory dumps (or automatic memory dumps on Windows 10).

Kernel memory

When you read file /proc/pid_of_process/maps, the kernel is simply going through the linked list of VMAs for the process and printing each one. In Windows, the EPROCESS block is roughly a mix of task_struct and mm_struct. Virtual Memory is used by the Linux kernel to allow programs to make a memory reservation.
