Hi ! When setting a mode on an LCD display that is not exactly the native mode of that display, we can, on some chips, setup a scaler. However, most of the time, we have 2 difference choices for setting up this scaler: It can preserve or not preserve the aspect ratio. A typical example is the titnium powerbook's 1152x768 mode. If I set it to 1024x768, I can get either horizontal scaling (not preserving aspect ratio) or no scaling with black bars on left & right (preserving aspect ratio). While in most case you actually want to preserve the aspect ratio, it would still I beleive make sense to let the user choose it. Could we define one of the reserved fields in fb_var_screeninfo as beeing a "flags" field for such things ? There are a couple of other things that we may want to stuff into such a bitfield later, I'd suggest reserving one 32 bits field for such flags. Ben. -- Benjamin Herrenschmidt <be...@ke...> |
