Firmware Test Suite - apicedge test

This test sanity checks APIC irq edge/level configuration. The rule of thumb is as follows:

  • Interrupts < 16 should be edge triggered

  • Interrupts >= 16 should be level triggered

  • The ACPI interrupt should be level triggered.

The data is gathered from /proc/interrupts, parsed and checked.


fwts apicedge -

..runs the test on your machine and dumps the output to stdout.

Explanation of test results

Certain test results may require a little more explanation. This section will try and give some context to specific test failures.

Error ID



ACPI interrupt is edge triggered and should be level triggered.


Legacy interrupt is level triggered and should be edge triggered.


Non-legacy interrupt is edge triggered and should be level triggered.
