The firmware files in turn should work their way into linux-firmware.git soon for being easily picked up by the various Linux distribution vendors (update: they are now in linux-firmware.git already).
Nice. Guess that means it won’t be long until they are in Bazzite and other distros.
Is this something that will be pushed to Steam Decks automatically?
I would expect so. It might already be on the Deck, as sometimes Valve is ahead on kernel and firmware related issues.
I doubt it; AMD just released these files, and even if Valve did have access to them for testing, they wouldn’t have rolled them out yet.
I think it would come down within an entire SteamOS update. Valve should give it some time in Testing before they push it to everybody in Stable. But they have been known to yolo some really wonky builds on a Friday afternoon and leave your Deck broken all weekend.
