- The Virtual Processor Interface: linux kernel Support for User-Level Thread Systems
- Despite an increasing need for thread support in language run-time systems and parallel libraries such as in Java and OpenMP, there is limited support for custom, multiprocessor capable, user-level thread systems in the Linux kernel. To address this lack of support the authors have developed the Virtual Processor Interface VPI...

- Embedded Real Time linux kernel Design Using Game Theory and Control Logic
- This paper describes a distributed hybrid architecture that imparts autonomous intelligence capabilities of the "Perception-decision-action" to an ALV Autonomous Landing Vehicle control unit. The system is shown to degenerate to a remote thread execution mechanism of a real-time operating Linux system where the kernel instantiation is control strategy dependent. This...

- Unintrusively Measuring linux kernel Execution Times
- This paper presents a methodology to perform fine-grained cycle-accurate timing measurements crossing the user-kernel boundary. Special attention is payed not to deteriorate the results by the measurement process itself. Next, it applies the methodology to obtain execution timing for the system entry and exit paths on x86-based Linux systems. This...

- Investigating Large Software System Evolution: The linux kernel
- Large multi-platform, multi-million lines of codes software systems evolve to cope with new platform or to meet user ever changing needs. While there has been several studies focused on the similarity of code fragments or modules, few studies addressed the need to monitor the overall system evolution. Meanwhile, the decision...

- Improving Verification, Validation, and Test of the linux kernel: The Linux Stabilization Project
- Small projects tend to have virtually no testing performed by anyone other than the author of the program. Larger projects depend upon a community of users to find and fix problems through use rather than disciplined test methods. The Linux kernel is becoming an exception. In this case an increasing...

- linux kernel do_brk() Vulnerability
- A critical security bug has been found in the Linux kernel 2.4.22 and earlier memory management subsystem. This bug has been silently fixed for the 2.4.23 as well as in the 2.6.0-test6 release without any notice to the open source community. While performing a regular audit of the Linux kernel...

- Utilizing linux kernel Components in K42
- This paper discusses how K42 uses Linux-kernel components to support a wide range of hardware, a full-featured TCP/IP stack and Linux le-systems. An examination of the run-time environment within the Linux-kernel is the starting point for a presentation of the strategy taken to incorporate Linux-kernel code in K42. There are...

- Yearning for the days of rolling your own kernel
- It used to be, you know - back in the day, that you almost always had to roll your own Linux kernel. Inevitably, there was a feature you needed or a bit of hardware unsupported in the standard kernel. Be it a specific networking card, sound card, wireless...you name it...we...

- linux kernel in a Nutshell: Configuring and Building
- The kernel configuration is kept in a file called .config in the top directory of the kernel source tree. If one has just expanded the kernel source code, there will be no .config file, so it needs to be created. It can be created from scratch, created by basing it...

- Tuning the linux kernel for more aggressive network throughput
- The Linux kernel and the distributions that package it typically provide very conservative defaults to certain network settings that affect networking parameters. These settings can be tuned via the /proc filesystem or using the sysctl program. The latter is often better, as it reads the contents of /etc/sysctl.conf, which allows...

- The Linux operating system kernel is a large, mature, freely available, and well-tuned concurrent program. As such it is an ideal workload for a transactional memory hardware design. Operating systems need transactional memory for performance scalability, to help maintainability, and to provide services related to transactions to user programs. Most...
