Setting Interrupt Priorities in Software via Interrupt Queueing
نویسنده
چکیده
When hardware intemrpt priorities don't match the needs of software, operating system designers often just suffer in silence. '!Ve describe an alternative here: simulating the hardware priority interrupt queueing mechanism in software, but assigning the (software) intemrpt priorities as we wish. This was done on an AMD 29200 microconffoller [Advanced Micro Devices 19941 which has effectively only two intemrpt levels: the clock and ever¡hing else. @1996 The USENIX Association, Computing Systems, Vol. 9 . No. 2 . Spring 1996 lI9

Modeling and Analysis of OS Performance in High-Speed Networks
Interrupt overhead of high-speed network devices can have a significant negative impact on the performance of traditional operating system. The negative impact is primarily due to interrupt overhead associated with the intense arrival of high-speed network packets. This paper presents models and analytical techniques for capturing the behavior and studying the performance of interrupt-driven ke...
متن کاملThe Limitations of Fixed-Priority Interrupt Handling in PREEMPT RT and Alternative Approaches
Threaded interrupt handling is a common technique used in real-time operating systems since it increases system responsiveness and reduces priority inversions. The PREEMPT RT Linux kernel patch introduces aggressive threaded interrupt handling into the Linux kernel. However, under PREEMPT RT, interrupt handling threads must be assigned a single fixed scheduling priority. This can become a signi...
متن کاملDesign and Development of an Agorithm for Prioritizing the Test Cases Using Neural Network as Classifier
Received Nov 4, 2014 Revised Jan 5, 2015 Accepted Feb 5, 2015 Test Case Prioritization (TCP) has gained wide spread acceptance as it often results in good quality software free from defects. Due to the increase in rate of faults in software traditional techniques for prioritization results in increased cost and time. Main challenge in TCP is difficulty in manually validate the priorities of dif...
متن کاملThe Design of a Synthesis Tool for Interrupt-based Real Time Embedded Software
There is a general lack of CAD tools for real-time embedded software, thus we have developed a software synthesis tool with a graphical user interface for real-time embedded systems. We propose an Interrupt Time Petri Nets (ITPN) model for real-time embedded software requirements modeling. ITPN can handle both interrupt behavior and real-time constraints on tasks in a real-time embedded system....
متن کاملEffects of Interrupt Coalescence on Network Measurements
Several high-bandwidth network interfaces use Interrupt Coalescence (IC), i.e., they generate a single interrupt for multiple packets sent or received in a short time interval. IC decreases the per-packet interrupt processing overhead. However, IC also introduces queueing delays and alters the “dispersion” (i.e., interarrival time spacing) of packet pairs or trains. In this work, we first expla...
