Wireless device not working during install

wamserma · June 19, 2023, 6:35am

If you have some means to circumvent the rtw89 for installation (ethernet, USB-Wifi) it might be possible to get the rtw89 working afterwards.

NixOS is using this driver:

It is packaged here:

let
  modDestDir = "$out/lib/modules/${kernel.modDirVersion}/kernel/drivers/net/wireless/realtek/rtw89";
in
stdenv.mkDerivation {
  pname = "rtw89";
  version = "unstable-2022-12-18";

  src = fetchFromGitHub {
    owner = "lwfinger";
    repo = "rtw89";
    rev = "e834edfe8bee6e27e31c2f783817a9c13ff45665";
    sha256 = "19ApYiEvA0E6qgf5XQc03paZ+ghjZL8JoC3vSYYw3xU=";
  };

  nativeBuildInputs = kernel.moduleBuildDependencies;
  makeFlags = kernel.makeFlags ++ [ "KSRC=${kernel.dev}/lib/modules/${kernel.modDirVersion}/build" ];

  enableParallelBuilding = true;

and it probably needs an update which hopefully also fixes the issues with 5.15 LTS:

### Describe the bug *Working with nixos-unstable* I have a notebook `T14s G…en1` which requires the `rtw89` kernel module for wifi. This module worked for me until an upgrade on May 20 (after roughly a month of no updates). Since then, the module doesn't work anymore on Kernel 5.15 (but I had a working configuration on 5.15.36). The config I had until it broke, was simply the following line in my config: ``` boot.extraModulePackages = with config.boot.kernelPackages; [ rtw89 ]; ``` Since nothing has happened with the kernel module itself I assume it relates to following issue [splitting up firmwares](https://github.com/NixOS/nixpkgs/issues/148197). Another possibility is that there is simply a bug in the kernel module which might already be fixed upstream and we need to upgrade it. ### Steps To Reproduce 1. Have a laptop with a Realtek 8852: ``` lspci | grep Network 03:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device 8852 ``` 2. Use the following in your `hardware-configuration.nix` and use Kernel 5.15.X ``` boot.extraModulePackages = with config.boot.kernelPackages; [ rtw89 ]; hardware.firmware = [ pkgs.rtw89-firmware ]; # optionally make sure you use kernel 5.15 #boot.kernelPackages = pkgs.linuxPackages_5_15; ``` 3. Rebuild the config and reboot The following stack trace appears in dmesg and wifi won't work: ``` [ 11.387364] rtw89_pci 0000:03:00.0: Firmware version 0.13.24.0, cmd version 0, type 1 [ 11.387371] rtw89_pci 0000:03:00.0: Firmware version 0.13.24.0, cmd version 0, type 3 [ 11.389419] BUG: unable to handle page fault for address: ffffb2e9427f25d4 [ 11.390477] #PF: supervisor write access in kernel mode [ 11.391428] #PF: error_code(0x0003) - permissions violation [ 11.392056] PGD 100000067 P4D 100000067 PUD 100193067 PMD 10981e067 PTE 80000001061f8161 [ 11.392975] Oops: 0003 [#1] SMP NOPTI [ 11.393572] CPU: 2 PID: 910 Comm: systemd-udevd Tainted: G O 5.15.46 #1-NixOS [ 11.394270] Hardware name: LENOVO 20UH0056MZ/20UH0056MZ, BIOS R1CET67W(1.36 ) 10/20/2021 [ 11.394958] RIP: 0010:rtw89_fw_download+0x6a/0x3e0 [rtw89core] [ 11.395496] Code: c2 48 8b 28 44 8b 48 08 48 85 ed 0f 84 7f 0e 02 00 45 85 c9 0f 84 76 0e 02 00 0f b6 45 19 b9 e4 07 00 00 49 01 e9 48 8d 75 20 <66> 89 4d 1c 8d 78 02 88 44 24 10 c1 e7 04 89 7c 24 14 48 63 ff 48 [ 11.396292] RSP: 0018:ffffb2e94174ba98 EFLAGS: 00010296 [ 11.397184] RAX: 0000000000000003 RBX: 00000000000000ff RCX: 00000000000007e4 [ 11.397327] RDX: ffffa05574402120 RSI: ffffb2e9427f25d8 RDI: ffffa05574402000 [ 11.398330] RBP: ffffb2e9427f25b8 R08: 0000000000000088 R09: ffffb2e942853930 [ 11.399119] R10: 0000000000000000 R11: 0000000000000002 R12: 0000000000000000 [ 11.400265] R13: ffffa05574402000 R14: ffffa05574402000 R15: ffffa05540ff10c8 [ 11.400710] FS: 00007f770818cd40(0000) GS:ffffa0583f880000(0000) knlGS:0000000000000000 [ 11.401302] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 11.402054] CR2: ffffb2e9427f25d4 CR3: 0000000102434000 CR4: 0000000000350ee0 [ 11.402908] Call Trace: [ 11.403531] <TASK> [ 11.404990] ?
