This isn't just about Fedora bringing some things to the table to make

upstream more interested in it, and my reasoning for suggesting they
aren't is when my particular regression came up I was surprised to
learn from the Fedora kernel team that laptops don't get much upstream
testing. If they aren't looking for such regressions, they will not be
found early on. When they're looking for particular regressions, they
are found early on. Not rocket science. This responsibility also lies
with hardware manufacturers, but how can the testing and reporting be
made easier, as in, more automated?
I can bring an example of the broken hotkeys on some laptops which I
thought Fedora kernel could fix and was suggested to report upstream.
One of upstream Linux kernel developers even temporarily brought the
laptop in question (in my case Asus X550ZE) for debugging. We discovered
a new boot scheme method from BIOS/UEFI vendors used by Windows 8.1 and
onward, we realized how far behind the Linux kernel was for years.
To be fair, one of issues on Linux kernel development are manpower.
Without the involvement from the reporters, developers would have hard
time figured out the problem.
The good news is the fix just landed on the main kernel branch,
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?i...
which should be available in Rawhide in a few days. Hopefully affected
laptops notably ASUS model will regain their hotkeys functions. I just
closed the year reported bug:
