MPFS_GPIO Level-triggered Interrupt Bug

[Eoin-Dickson]

Description

There is a problem in how to the GPIOInterruptManager is dealing with level-triggered interrupts for the MPFS_GPIO peripheral. According to the GPIO SAC specifications when the input that is causing a level-triggered interrupt is removed, then the interrupt should de-assert by itself.

Expected behaviour

Once the input causing a level-triggered interrupt is removed then the interrupt should go back to 0

How to reproduce?

I have tried this with a local project and it results in the interrupt staying high rather than de-asserting itself.

Environment

Windows
Renode 1.14.0

Do you plan to address this issue and file a PR?
