What is irqbalance

das Paket irqbalance verteilt ja die Interrupts gleichmäßig zwischen mehreren CPUs. Setzt man jetzt jedoch einen RT Kernel wie z.B. linux-image-rt-amd64 ein verwendet der Kernel für die IRQ-Verwaltung Threads. Mit dem Paket rtirq-init werden diese Threads dann priorisiert.

Performance Tuning¶. Apache Traffic Server™ in its default configuration should perform suitably for running the included regression test suite, but will need special attention to both its own configuration and the environment in which it runs to perform optimally for production usage.
The purpose of irqbalance is to distribute interrupts accross cpus in an smp system such that cache-domain affinity is maximized for each irq. In other words, irqbalance tries to assign irqs to cpu cores such that each irq stands a greater chance of having its interrupt handler be in cache when the irq is asserted to the cpu.

Giving us the option to enable manually control which core we want certain IRQs to run on, and the option to have irqbalance to do this for us. Both are possible at the same time since irqbalance has the option to ignore certain IRQs if this is desired.

I assume you enabled HT system-wide (in BIOS), prevented the OS from using a group of PUs (via isolcpus, IRQBALANCE_BANNED_CPUS, or both), and configured ThreadConfig in a particular way. Did you simply leave the 2nd PU of each HT group unbound for all "non-HT" threads? 9:52 PM

Jan 27, 2017 · All irqbalance does is writes values to /proc/irq//smp_affinity, and then the IRQ core in the kernel takes over from there. irqbalance is doing exactly what "echo > /proc/irq//smp_affinity" will do. Nothing more. irqbalance is a userspace daemon that has been available for a number of years. Its main purpose is to make decisions on how to best balance interrupts within a system.irqbalance is a Linux daemon that distributes interrupts over among the processors and cores in your computer system. irqbalance is relevant on multiprocessor x86, x86_64, and AMD systems.The irqbalance packages provide a daemon that evenly distributes the interrupt request (IRQ) load across multiple CPUs for enhanced performance. This update fixes the following bug: Previously, if a device disappeared and then reappeared, the "irq_count" interrupt request (IRQ) counter in irqbalance overflowed, which resulted in a failure to balance IRQs.

Dec 10, 2019 · This is a standard Linux application that looks for information about running processes on a Linux system. It is used to list the currently running processes and their process ID (PID), process owner name, process priority (PR), and the absolute path of the running command, etc,. Giving us the option to enable manually control which core we want certain IRQs to run on, and the option to have irqbalance to do this for us. Both are possible at the same time since irqbalance has the option to ignore certain IRQs if this is desired.
