Big thanks for making the website. I stumbled upon it a few days ago and I'm pretty happy that somebody pointed my attention towards this.

The parameter list could be even reduced to fewer elements as mitigations=off covers nopti, nospectre_v1, nospectre_v2, l1tf=off, nospec_store_bypass_disable and mds=off.[1]

That seems to depend on kernel version. So just add them all. Better safe than sorry... I mean... unsafe than sorry.

Isn't mitigations=off enough on newer kernels?

Yes. Its also been added into various LTS versions about five or six months ago.

ctrl+f: cpu/speculation: Add 'mitigations=' cmdline option

it is, but I know a fair amount of people on older distros - ubuntu 16.04, 18.04, etc... whom may have some flags available but not mitigations=off which is a more recent addition

One of the article's comments says so.

Thank you for that website. As I disable mitigations on all my personal hardware, this saved me a bit of time when this whole thing started and has served as a nice quick reference since.

That looks cool. Always wanted to know though, do you benefit something from such websites? Just interested, thanks!

As the owner of a couple vanity domains for no useful purpose, no, I don’t “benefit” from it. In fact, each domain costs me a small amount of money. But the amusement I get from them makes it worth it. :)

As someone also with a few dozen vanity domains. The benefit is learning how to manage multiple web properties with minimum resources. It costs me about $500/year in domain registration alone. I would consider it my hobby as well, but it makes us a shoe-in candidate for a lot of technical positions because we dont need to tell we can simply show.

Why don't you put them on a tld that'll give you cheap domains?

Then they’re not vanity domains anymore (;

I’ve been doing this for 20 years, all discounts found and baked in. FWIW all of my demo sites since last summer use .xyz before they become full fledged vanity domains

it's a net loss of 10€ a year but makes me happy which certainly improves my cardiovascular health :p

They seem not. Just one line is nothing. Need to read the f info about kernel.

yes, that was tongue in cheek - actual work is done by people writing the kernel
