Nice, you got nothing.

The industry is more than just Intel and Intel are an outlier with respect to Linux kernel development.

Intel is not an outlier with respect to PCs. Which we are talking about. Specifically, "the big laptop manufacturers", who are PC manufacturers. These are the manufacturers who are making the overwhelming majority of these Handhelds. Again, not some 1 off ARM vendor.

They already do: https://gitlab.com/evlaV/linux-integration https://gitlab.com/evlaV/linux-integration/activity

Again, you got nothing. All you have left is disingenuous links. Valve works from a fork, like everybody else. You know good and well, Google is doing something very different with their Android Kernel. https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/?qt=grep&q=Valve Valve, and all their contractors work to mainline their additions/changes to Valves fork. I can build a recent Linux kernel from the mainline and use it to boot my Steam Deck.

I'm shocked that this is news for you but, it's not just Intel who works off their own forks of the different Windows kernels. We get our drivers certified with WHQL and then hand them off to the OEMs who use our IP for release with their devices. In parallel work is done with Microsoft engineers to inbox the drivers. Valve is doing nothing different. Valve does the exact same thing with their fork of Linux. There is no reason to expect anything different out of Valve, Intel, or any other company or individual.

No offence mate but you’re talking bollocks. You clearly don’t know anything about Linux development.

Scuttle the argument how you like. You have nothing so it's to be expected. We are clearly talking about OP's claim, which is for the PC industry. Not Linux development. "the big laptop manufacturers", remember? You can go around and talk about all the "1 off ARM vendors" out there and how poor their practices are and how little they offer; knock yourself out. OP specifically said, "the big laptop manufacturers". I outline why he is correct in his claim from my direct industry experience. These laptop manufacturers are going to expect the same white glove treatment working with SteamOS as they do for Windows. The exact same treatment AMD did for Valve.

Sounds like you have zero experience with the PC industry and zero experience with even one of "the big laptop manufacturers".
