Specifically, data from the associated struct irq_desc. The information here is similar to that in /proc/interrupts but in a more machine-friendly format. This directory contains one subdirectory for each Linux IRQ number. What: /sys/kernel/irq/<irq>/actions Date: September 2016 KernelVersion: 4.9 Contact: Craig Gallek <kraig@google.com> Description: The IRQ action chain. A comma-separated list of zero or more device names associated with this interrupt. What: /sys/kernel/irq/<irq>/chip_name Date: September 2016 KernelVersion: 4.9 Contact: Craig Gallek <kraig@google.com> Description: Human-readable chip name supplied by the associated device driver. What: /sys/kernel/irq/<irq>/hwirq Date: September 2016 KernelVersion: 4.9 Contact: Craig Gallek <kraig@google.com> Description: When interrupt translation domains are used, this file contains the underlying hardware IRQ number used for this Linux IRQ. What: /sys/kernel/irq/<irq>/name Date: September 2016 KernelVersion: 4.9 Contact: Craig Gallek <kraig@google.com> Description: Human-readable flow handler name as defined by the irq chip driver. What: /sys/kernel/irq/<irq>/per_cpu_count Date: September 2016 KernelVersion: 4.9 Contact: Craig Gallek <kraig@google.com> Description: The number of times the interrupt has fired since boot. This is a comma-separated list of counters; one per CPU in CPU id order. NOTE: This file consistently shows counters for all CPU ids. This differs from the behavior of /proc/interrupts which only shows counters for online CPUs. What: /sys/kernel/irq/<irq>/type Date: September 2016 KernelVersion: 4.9 Contact: Craig Gallek <kraig@google.com> Description: The type of the interrupt. Either the string 'level' or 'edge'. What: /sys/kernel/irq/<irq>/wakeup Date: March 2018 KernelVersion: 4.17 Contact: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Description: The wakeup state of the interrupt. Either the string 'enabled' or 'disabled'. |
