No one is saying that we don't want a framekwork to provide this
information... We want to put the framework in the proper place that
will be the most maintainable, testable and extensible location possible:
userland... A single bug in the kernel framework and associated drivers
could take the entire system down... The worse a userland app can do
is core dump...
Having recently written an HDTV driver... It was a god-send to have
the tuner logic and related items in userland, and only use the kernel
part as a bit mover.. It made testing very quick, and will enable
people to develope additional tuners w/o having to go through crashing
their machine as they load/unload drivers that contain bugs..
