Ummm..giving it a glance

@pdp7, or anyone else skilled in the #Linuxkernel arts, I have been chasing this bug [1] for months in my simulator and would really appreciate some hints. What would be a good strategy for finding out what the kernel is waiting for? I have checked the VirtIO implementation (which I didn't write) and I don't see anything obvious wrong, but no more requests are issued after the first few reads.
very long shot: do i know anyone who knows anything about linux's schedutil CPU governor?
i have this old microserver and the clock never leaves the lowest frequency (unless i tell it to manually). i have checked A Lot of things and everything looks correct, it just does not do anything even under high load.
it's a basic nixos install, but from everything i have checked i would be surprised if it's a disto specific issue.

Pro tip: always keep Hanlon's razor and Murphy's law in mind when considering writing headlines like the one show below – and then discard the headline.
Which would have been wise in this case, too, as the problem that triggered that reddit post turned out to be a script doing something odd that was hard to spot:

Linux 6.16 needs GCC 8 and Binutils 2.30
The upcoming version of Linux now needs at least GCC 8 and GNU Binutils 2.30 to be able to successfully build, because this was needed to remove all legacy code that provided workarounds for build systems prior to GCC 8, which became a maintenance burden. Previously, GCC 5 and Binutils 2.25 were required to build Linux, and the latest version, 6.15, had this requirement before 6.16 increased it.
GCC 8 and Binutils 2.30 brought new features that Linux 6.16 needed, while LLVM Clang 13 was the minimum requirement for Linux in case you’ll need to use LLVM instead of the legacy GCC.
You can see the merge request below.
See merge requestThe reasoning for this minimum version requirement bump is here:
x86 already uses gcc-8 as the minimum version, this changes all other architectures to the same version. gcc-8 is used is Debian 10 and Red Hat Enterprise Linux 8, both of which are still supported, and binutils 2.30 is the oldest corresponding version on those.
Ubuntu Pro 18.04 and SUSE Linux Enterprise Server 15 both use gcc-7 as the system compiler but additionally include toolchains that remain supported.
With the new minimum toolchain versions, a number of workarounds for older versions can be dropped, in particular on x86_64 and arm64. Importantly, the updated compiler version allows removing two of the five remaining gcc plugins, as support for sancov and structeak features is already included in modern compiler versions.
I tried collecting the known changes that are possible based on the new toolchain version, but expect that more cleanups will be possible.
Since this touches multiple architectures, I merged the patches through the asm-generic tree.”
