Right, Anton was working on enabling an FIQ mode kdb (along with
modifications to kdb to provide a safe kiosk mode), in order to replace
Android's FIQ debugger. The patches were sent to the lists and various
maintainers a number of times to almost no response. Sadly for us, Anton
went back to school, so the effort has stalled.
I tried to resubmit the patches (without deeply understanding them), but
again it didn't seem to get maintainer interest and the few questions
that did arise I wasn't able to answer effectively.
Its still on our todo list, and I'd love to see some progress on it, but
I just haven't been able to commit the time myself.
If anyone wants to take a look at it, Anton's work can be found here:
FIQ KDB:
git://git.linaro.org/people/jstultz/android-dev.git dev/fiq-kdb
https://git.linaro.org/gitweb?p=people/jstultz/android-dev.git;a=shortlog;h=refs/heads/dev/fiq-kdb
KDB Kiosk:
git://git.linaro.org/people/jstultz/android-dev.git dev/kdb-kiosk
https://git.linaro.org/gitweb?p=people/jstultz/android-dev.git;a=shortlog;h=refs/heads/dev/kdb-kiosk
It would be interesting to also hear feedback as to how close Anton's
kdb approach is to what you're thinking of trying to push upstream.
thanks
