This isn't my area of expertise, but I suspect this is going to cause some pretty confusing behavior. Generally speaking device capabilities are queried right after the frontend is opened, and the frontend capabilities typically don't ever change. In this case, an application would have to know to check the capabilities a second time after calling FE_SET_FRONTEND_TUNE_MODE in order to determine whether auto inversion *really* is available. If the goal was for the software-emulated auto inversion to be transparent to userland, perhaps it makes more sense for the oneshot mode to toggle the inversion if needed. The oneshot mode would continue to disable zigzag and the stats monitoring. I realize that this is a bit messy since it won't really be "oneshot", but I don't know what else can be done without breaking the ABI. Devin -- Devin J.
