The Linux Kernel Might Drop Memory Protection Extensions Support

[GunpowaderGuy]

no need for this , or address space layout randomization ( both of which may have unfixable flaws anyways ) when using a memory safe language

Then it's supported. And the article also mentioned that Intel is still sending patches for it upstream no?

Intel sending patches does not mean it runs decently or better than other competing methods that might be generic and not bound to yet another Intel-only gimmick.

For example Intel 2D driver for linux is still "developed", but many distros are switching to the generic modesetting 2D-acceleration-over-3D driver because it's less crappy and has a better future overall.

Nobody gives a flying f*** about servers.

Might amaze you, but Linux kernel development is more oriented towards server and embedded than desktop usecase.

Maybe they should be checking if MSVC and Windows even supported those features.

If the OS used by 90% of the world's desktop and laptop computers does not even support them, then just drop them from the kernel.

I don't see how Linux should care about support of features on Windows.

Only desperate fanboys who refuse to face reality resort to referencing obsolete data from 2016.

OK, park OS wars for a second... MPX (similar to AddressSanitizer) multiples memory and runs about half the speed. Coming back to OS, that's the relevance of developer platforms, rather than desktop or I agree server. (nice to meet you here, it's my first day posting, many years lurking)

It was added to MS Visual Studio 2015 Update 1 but just like with GCC you have to actively enable it when compiling and it requires Windows 10 in order to work. If the Windows 10 kernel uses MPX or not however I do not know, just that Intel released a MPX driver for Windows 10 to support apps compiled with MPX enabled.

Probably shouldn't be dropped if that is the case methinks.

Except the server market share isn't 90%!

Also, as a developer feature (rather than MPX being server ready) Linux may have 20% market share https://en.wikipedia.org/wiki/Usage_...ystems#Desktop and laptop computers
