== 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.

=== Examples: ===

{{{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||Explanation||
||ACPIIRQEdgeTrig||ACPI interrupt is edge triggered and should be level triggered.||
||LegacyIRQLevelTrig||Legacy interrupt is level triggered and should be edge triggered.||
||NonLegacyIRQLevelTrig||Non-legacy interrupt is edge triggered and should be level triggered.||
