This patch adds a scaling filter mode porperty to allow:
- A driver/HW to showcase it's scaling filter capabilities.
- A userspace to pick a desired effect while scaling.
This option will be particularly useful in the scenarios where Integer mode scaling is possible, and a UI client wants to pick filters like Nearest-neighbor applied for non-blurry outputs.
There was a RFC patch series published, to discus the request to enable Integer mode scaling by some of the gaming communities, which can be found here: https://patchwork.freedesktop.org/series/66175/

Two things:
- needs real property docs for this in the kms property chapter
Got it,
- would be good if we could somehow subsume the panel fitter prop into this? Or at least document possible interactions with that.
Sure, let me see what can I do here.
The scaling mode prop has nothing really to do with the filter being used. The scaling mode prop just provides a bad mechanism for configuring the destination coordinates of the scaler.
Trying to shoehorn these things into one prop would be a mistake IMO.
