User space interface for GPIO interrupts / Status Report Week 3

[Christian Krämer]

Hi,

this time my status report is unfortunately somewhat delayed, but here are proceedings of the last week: I managed to realise trigger type configuration during runtime and started to implement a handler for the poll() syscall. It is now also possible to configure multiple pins at once, each one with a different trigger type.

The plan for this week is to fix the remaining issues with the poll() syscall, along with some other minor issues and prepare a concept for a convenient interface of the driver that allows distinction which of the configured pins was actually triggered. I will also spend some time on working out a suitable scenario for automated long-term tests.

The source code of the driver can be found in my fork of the FreeBSD src tree on GitHub [1]. The utilities for configuration and testing are located in the following repository [2].  

Regards,
Chris
