Some old plus some new patches which mostly streamline the SDMA ring emission, plus a little bit of GFX ring padding optimisation.
More or less it is about replacing repeated runtime array walks (and conditionals in general) with direct lookups for things which are invariant at runtime. Smoke tested on Steam Deck only.
