Interrupts delivery latency
Webinterrupt delivery methods for IO (Input/Output) devices, providing many benefits, including a significant reduction in interrupt latency. Intel® architecture, consisting of a CPU, memory controller, and an IO controller, can provide the embedded developer with a competitive platform for embedded designs. Linux, a mature yet flexible open source WebMessage Signalled Interrupts ( MSI) are an alternative in-band method of signalling an interrupt, using special in-band messages to replace traditional out-of-band assertion of …

WebAn interrupt is an event that alters the normal execution flow of a program and can be generated by hardware devices or even by the CPU itself. When an interrupt occurs the current flow of execution is suspended and interrupt handler runs. After the interrupt handler runs the previous execution flow is resumed.

Below is a screenshot of what it looks like when you see the Log Reader Latency causing issues while “Number of commands” shows zero. This is Log Reader Agent status and you will see “Latency” as 16100 (ms) below. Webinterrupt latency is the number and length of regions in which the kernel disables interrupts. By disabling inter-rupts, the kernel may delay the handling of high priori-ty interrupt requests that arrive in those windows in which interrupts are disabled. Most operating systems employ what we call a Simple architecture: whenever
