I think what's talked about there does actually work in Linux (accessing an IRST created RAID0 setup on NVMe drives).

EDIT: See here, Intel's documentation about the feature:

If i read it right the only time when this feature is needed is when it used in RAID, but aside from this it isnt needed in AHCI so my statement still stands i think. There is no good reason to force RAID...

There are SATA and PCIe NVMe drives, it only works in Linux with the SATA variety.

Are you really, really sure you don't have it backwards? I think what's happening is that the remapping stuff was until very recently needed for Windows drivers to work, and now there's newer Windows IRST drivers that can do it without the remapping. Basically, the whole remapping thing was never a topic for Linux?

Linux has an even better licensing deal to offer tongue.gif

That would be a much better argument, but if you ever looked in a Lenovo BIOS, everything they can get away with is locked down hard. Always has been. Probably the single most useless BIOS out of any major OEM, which makes them infuriating to support.

The remapping function is the only reason the intel storage controller can even 'see' a PCIe SSD. The storage controller itself only controls SATA directly, it controls PCIe drives through I/O redirection inside the MMU. This requires something akin to a hypervisor to accomplish.

In the Intel Linux IRST tutorial I linked to earlier, in their examples they don't use SATA devices provided through the SATA controller. The disk is accessed directly as a PCI-E one. It shows up as a device "/dev/nvme0n1" for example, not "/dev/sda". From the Linux point of view, I think what's interesting about Intel's stuff is if the tools understand the IRST created RAID array on the disks or not, so if they'll get what changes you do in the BIOS menus or what's done on the Windows side when dual-booting.

I'm not seeing anything about using the drives as bootable media or using arrays created in the RST firmware.

Then there is the list of supported OS/Chipset combinations...

Soon we'll need to pay more for hardware that doesn't have hardware level OS lockdown.

Microsoft hasn't gotten any less genius about being savage against it's competition. It's just that they now see consumer choice as their competitor.

If you're not on Windows 10, you're not giving them metadata to sell to government / corporations. If they can keep you filling a page in their metadata sales catalogue, they can make money from you. If they can't, they intentfully punish you. How great is that?

You don't want windows? Have fun returning your laptop and finding one that supports installing a new operating system.

Hah, what a joke.

People continually ask why people are so upset that MS is going into big data. This is what comes with a corporate big data strategy. This is what happens when you stop valuing your privacy; someone else will.

They value it so much that they're lowering prices or even giving their goods away for free, just to record your personal day to day telemetry, social situation, financials, or whatever else other corporations can use to advertise on you.

Good thing everyone knows they're too smart to let it work on them. Otherwise presidential campaigns would just consist of buying metadata, statisticians, behavioural psychologists, and a favor or two from the big social media providers.

Luckily laws prevent all of these things.

Oh, wait, they kinda don't.
