Binary cache to save yourself a kernel build: https://app.cachix.org/cache/atemu

FWIW (I assume anecdotal feedback is helpful for a potential reviewer which is why I am commenting here and not on the Issue): I have been using this patch the last day on nixos-unstable (20.09pre235279.5717d9d2f7c (Nightingale)) and haven't encountered any issues so far.

Built it on NixOS with nvidia's unfree drivers, did not use the cache.

I am using following snippet for /etc/nixos/configuration.nix:

let
  nixpkgs-tars = "https://github.com/NixOS/nixpkgs/archive/";
  pr94027 = import (fetchTarball
    "${nixpkgs-tars}83451174b826146cedbc31d98f16c870a0dd0c45.tar.gz")
    { config = config.nixpkgs.config; };
in {
  boot.kernelPackages = pr94027.linuxPackages_zen;
}

Successfully built with the above snippet on NixOS with Intel's drivers (20.09pre236091.28fce082c8c (Nightingale)), without the cache too. No problems so far.

I just had i3 and journald crash on me and executing anything but dmesg resulted in a segfault afterwards. Looking at the dmesg suggested that that might've been due to nGreedia's proprietary crap but it could also be an incompatibility introduced by Nixpkgs.

I've been using this kernel ever since the PR was opened, so I'd like to have at least one more Nvidia (and preferably also ZFS) user test this for a few days before we merge.

I'm testing 5.7.10-zen1 since yesterday. So far no problems.

I've tested the kernel on both Amd and Intel hardware and everything works perfectly for me.
I didn't really expect it, but most of my programs feel more responsive, especially Firefox feels noticeably snappier with this kernel.

Specific things tested:
ZFS, zram, web browsing, video playback and the rtl8821CE module; updated via overlay from: #94157

@samuelgrf - cool to see this working w/ that wifi driver--when I first switched to NixOS I gave up on trying to use the zen kernel when I couldn't get the two to play nice.

Doesn't looks like there are any changes to be made, and it doesn't looks like there are some obvious issues, so I guess it is good enough…

Thanks for the heads up, I didn't actually consider this. I assumed the patches would activate themselves by default and didn't verify. Looks like that is the case though.

The RQ related config flags aren't set but those don't seem to be used anywhere in the source.

Oh, they deleted their comment :S
