Simple ioctl where the application passes an integer value to define a video mode. Used by the current Milkymist framebuffer driver, might be replaced by something more complete in the future.

Replying to comment:23:

I don't see any ioctl's in linux/fb.h to set anything except the cursor.

There are some "PUT", e.g. to change the color map.

Linux, the driver author "knows better" than the user, thus no control over
details like this. Ultimately, it can't be used as a model for RTEMS because
we assume the user is smart and may have a good reason to switch some settings.

Maybe, but the RTEMS user is quite alone.
