IMO this provides a better explanation.

Matthew Garrett is correct and not correct, throughout that article.

The fake RAID mode is designed to work around a limitation in Windows. Windows can't do driver overrides, so putting it in "RAID" forces it to load the Intel driver with better power management. That much is true.

But...

Removing the AHCI option and writing new code to write protect the RAID setting from being toggled with an EFI variable amount to a Linux lockout mechanism. Linux wouldn't benefit from having a driver for the RAID controller other than getting around the lockout. Power management would be the same in Linux in either mode.

If you read the comments, the better solution is probably having Linux kick the controller into AHCI mode after GRUB hands over. GRUB is using the uEFI disk access, but Linuxx can't use uEFI access because performance would suck. Putting the controller in AHCI mode with Linux before PCI device enumeration would take a few lines of code, while writing RAID controller support might take months. So ignoring the RAID controller and bringing the device back up in native AHCI mode is the better solution, if it can be done (Garrett isn't sure if the hardware allows that, but he said he'd look into it.).

I sometimes wonder why I submit myself to indignities of reading that Microsoft shill and that shit site in general. This kind of corporate garbage should be a bannable offense of /v/Linux.

Edit, also have an archive.

Don't give a single click to that Microsoft whore.

It might be a coincidence but the OP was called out here in the comments last week: https://voat.co/v/Linux/comments/1284835

I've just checked the author of all the zdnet articles submitted a nd gone to his bio page:

Steven J. Vaughan-Nichols, aka sjvn, has been writing about technology and the business of technology since CP/M-80 was the cutting edge, PC operating system; 300bps was a fast Internet connection; WordStar was the state of the art word pro…cessor; and we liked it.His work has been published in everything from highly technical publications (IEEE Computer, ACM NetWorker, Byte) to business publications (eWEEK, InformationWeek, ZDNet) to popular technology (Computer Shopper, PC Magazine, PC World) to the mainstream press (Washington Post, San Francisco Chronicle, BusinessWeek

Given the SN name here, there's a very fair chance you are replying to the author of that article.

It's not a coincidence. It says right there that sjvn is him. Look, I have no problem people promoting their own writing here. If I had a Linux related website I'd post my stuff here as well, I'd even tell you guys that it was me and I'd pay Voat ads for it, I don't give a shit I play in an open field. What I really fucking dislike is his corporate cocksucking, his Microsoft is now good and loves Linux bullshit he's being paid to spread around here. Like I've said several times before, Microsoft loves Linux unless you're using it. They love it on their servers and their networks, because Windows is complete fucking garbage for everything these days, they hate it on your computers.

I don't know what is to be done with this shill. I'll leave it to you, you're the mod around here. But I will call him out, fuck that guy.

Yeah what I pretty much expected, Lenovo. Some said MS, some said Intel. No, it was Lenovo again. Fucking idiots.

Also, RAID on a single drive system? can someone please explain how is that arrange a performance booster?

Bullshit article. Are you really telling me that Lenovo intentionally crippled this line of laptop to a single OS, without any kickback from the company whose OS is the only one that will work on the hardware?

Where is the incentive, where is the profit? The fact that these "special" laptops don't come with bloatware as well, tells me that they must be getting additional funding from somewhere to offset the lack of money from the bloatware makers.

Mark my words, Microsoft have provided extra incentive to Lenovo to limit support to a single OS.
