What: /sys/kernel/irq |
|
Date: September 2016 |
|
KernelVersion: 4.9 |

Contact: Craig Gallek <[email protected]> |
|
Description: Directory containing information about the system's IRQs. |
|
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 <[email protected]> |
|
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 <[email protected]> |
|
Description: Human-readable chip name supplied by the associated device |
|
driver. |

|
Description: When interrupt translation domains are used, this file contains |
|
the underlying hardware IRQ number used for this Linux IRQ. |
|

|
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 <[email protected]> |
|
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 <[email protected]> |
|
Description: The type of the interrupt. Either the string 'level' or 'edge'. |

|
'enabled' or 'disabled'.
