The link I am posting is to the original scitech code which is free to use. I have a bunch of versions on my local machine but none are up to using all of the new sysfs APIs. Looking at the sysfs calls it is simple to convert the reset app to use them. The reset app is already trapping the io/out instructions.
Instead I have been concentrating on feeding new babies and getting the last two pieces of kernel support in. We still need a solution for VGA routing (I posted on but the design needs work) and making the initial user space call out.
I would prefer to use hotplug for the user space call out but when I do I run into the framebuffer and DRM drivers. This having multiple drivers for the same piece of hardware is a pain. So hotplug on the standard device is not an option.
Other options would be to directly call_usermodehelper() or create a temporary class device for each VGA card as it is found. The temp VGA device would trigger the reset app. They would be temp since there may be multiple ones.
