Lınux Çekirdeğinin Gerçek Zaman Performansının Ölçüm Yükü Getirilmeksizin Ölçülmesi

Abstract

Linux çekirdeğindeki gerçek zaman performansını etkileyen mekanizmalar incelenmiş, Linux’un niçin katı gerçek zamanlı olmadığı ortaya konmuştur. Linux işletim sisteminin gerçek zaman performansını geliştiren yaklaşımlar incelenmiştir. Linux gerçek zaman performansını ölçüm yükü getirmeksizin ölçebilen bir sistem tasarlanmıştır. Ayrıca, mikroişlemci tabanlı bir devre geliştirilmiş olup, bu devre sayesinde gerçek koşullara uygun ayarlanabilir kesme işaretleri oluşturabilmektedir ve bu kesme işaretlerine göre Linux gerçek zaman performansı ölçülebilmektedir.

Linux kernel mechanisms that are influence on real-time performance and all available approaches to make Linux more real-time were analyzed. In addition, we developed a method to perform unintrusively measurement of Linux real-time performance. To achieve unintrusively measurement, an embedded system is developed to generate interrupts to Linux machine with adjustable timing via host machine user interface program to simulate real world events most accurately.
