Hi,
The stable kernel 4.9.112 has supported Intel uncore feature in perf core. While it also needs the perf tool supporting to let perf uncore feature work.
Following backport patches enables basic perf uncore feature in 4.9.112.
For example, on skylake desktop,
Why would anyone care about this on a "desktop" for 4.9? No one should be using 4.9.y on a desktop anymore, it's over 2 years old, why would they expect any "new" hardware support to work for them? Why can't they
It's actually not new hardware support: Skylake is fairly old hardware at this point.
just use 4.14.y or better yet. 4.17.y? Desktops should NOT be using a 2 year old kernel.
Heck, servers shouldn't either, but that's a totally different rant.
These chips are not only used in desktops but also in servers.
However, for hardware that is newer than the base kernel version release, I have no sympathy. Just use a newer kernel, right?
We have customers which are on old kernels with new hardware. The backports happen either way. This is just an attempt to do it in a coordinated fashion.
What distro relies on a 4.9 kernel for brand new hardware that does not already support a newer kernel release for such hardware?
None afaik, but there is a lot of Linux use beyond distros.
