Linux 5.12 Released With Intel Xe Variable Rate Refresh, Clang LTO, KFENCE + More

[Aeder]

So Intel doesn't even have their graphics cards out yet and they have adaptive sync, but yet my video card from another vendor is just finally getting it after many years.

It could be worse, you could have the same problems I do with my Intel+AMD laptop which went from perfectly supported to not booting with Kernel 5.11

Are you talking about nouveau, or yet another vendor? amdgpu DC has had the corresponding support for years.

It was a smooth upgrade this time around.
Custom Linux 5.12, with Virtualbox 6.1.20, NVidia 465.24.02 building right out of the box, without fixes.

Maybe I'm out of the loop, but does this mean there are no issues building the kernel with Clang? I thought only GCC was really supported.

OpenMandriva use Clang kernel.

As mentioned in the article about it, the Xe graphics targeted by this change are primarily found in Tiger Lake (in Laptops & SFF PCs since late last year) and Rocket Lake (in desktops since the end of last month):

This is going to be the coolest version of Linux:

5.12 = 2⁹ / 10²

...until 10.24, which has an even nicer symmetry.

Xe has been available for a while, as iGPUs.

I'd love to see Paragon's NTFS replace the old driver
As far as I know PATCHv26 has been sitting in the mailing list since April 4

I mean the driver is still buggy (broken inodes? I don't know how to call it), which does not happen on the proprietary UFSD NTFS driver made by them, so I guess the kernel people at least wants that kind of quality before merging it into tree.

Also I don't see signs of 5.12.0 on kernel.org, which made me really confused


There's also no signs of 5.12.0 builds on Fedora Bodhi

On Ubuntu, the mainline monkey compiled the kernel-headers to require Hirsute/21.04 for this kernel.

One day, I'll stop installing dot zeros.

In the time needed to complain you could have already built one for yourself using the older distribution's compilers.

Does this release contain the the bits needed to operate both the Intel iGPU and the Xe dGPU together, without resorting to VM trickery?
