This changes the NVIDIA NixOS module to use ICD libraries built from
source rather than relying on the pre-compiled bundled versions.
Additionally, this adds a necessary workaround for driver versions
below 595 to ensure proper compatibility.
For more context on the workaround, see the discussion at:
https://github.com/NixOS/nixpkgs/pull/497342#issuecomment-4034876793
It's hard to put the sourcing of ./.attrs.sh into all builder
consistently - mistakes will happen. Thus, load structured attrs once in
make-derivation and then source the remaining builder on top.
This should fix quite a few builders with structured attributes in
principle. Most importantly it helps substitute / substituteAll, which
are required for bootstrap on some platforms.
When specifying the `builder` attribute in `stdenv.mkDerivation`, this
will be effectively transformed into
builtins.derivation {
builder = stdenv.shell;
args = [ "-e" builder ];
}
This also means that `default-builder.sh` is never sourced and as a
result it's not guaranteed that `$NIX_ATTRS_SH_FILE` is set to a correct
location[1].
Also, we need to source `.attrs.sh` to source `$stdenv`. So, the
following is done now:
* If `$NIX_ATTRS_SH_FILE` points to a correct location, then use it.
Directly using `.attrs.sh` is problematic for `nix-shell(1)` usage
(see previous commit for more context), so prefer the environment
variable if possible.
* Otherwise, if `.attrs.sh` exists, then use it. See [1] for when this
can happen.
* If neither applies, it can be assumed that `__structuredAttrs` is
turned off and thus nothing needs to be done.
[1] It's possible that it doesn't exist at all - in case of Nix 2.3 or
it can point to a wrong location on older Nix versions with a bug in
`__structuredAttrs`.
nvidia 470.57.02 changed the path of `nvidia-sleep.sh` and systemd
scripts, making `builder.sh` miss them and suspend-to-ram on systems
where `hardware.nvidia.powerManagement.enable = true` is set fail.
Ignore the sanity check that prevents the Nvidia drivers from
being built for kernels with real-time patches.
Even though the driver might not be officially supported by
Nvidia for linux-rt, it seems to work without issues.
Attempting to install the driver for linux-rt fails with the
following error message:
The kernel you are installing for is a PREEMPT_RT kernel!
The NVIDIA driver does not support real-time kernels. If you
are using a stock distribution kernel, please install
a variant of this kernel that does not have the PREEMPT_RT
patch set applied; if this is a custom kernel, please
install a standard Linux kernel. Then try installing the
NVIDIA kernel module again.
*** Failed PREEMPT_RT sanity check. Bailing out! ***
The original file contains just a library name, which does not work when LD_LIBRARY_PATH does not contain /run/opengl-driver/lib, as is the case in unstable NixOS.
Fixes https://github.com/NixOS/nixpkgs/issues/69264
nvidia_x11 and persistenced were modified to provide binaries which can be
mounted inside a docker-container to be executed there.
most ldconfig-based discovery of bundled nvidia libraries is patched out
ldconfig itself is patched to be able to deal with patchelf'ed libraries
