Some nvidia devices, such as the Jetson family, support the Nvidia compatibility package (nvidia_compat) which allows to run executables built against a higher CUDA major version on a system with an older CUDA driver. On such platforms, the consensus among CUDA maintainers is that there is no downside in always enabling it by default.
This commit links to the relevant cuda_compat shared libraries by patching the CUDA core packages' runpaths when cuda_compat is available, in the same way as we do for OpenGL drivers currently.
After testing on a Jetson device, it turns out `cuda_compat` requires libnvdla_runtime.so which can't be satisfied by autoPatchElf, as it is provided by the runtime driver. This commit simply adds this library to the list of dependency to be ignored by autoPatchElf.
cudaPackages.cuda_compat: ignore missing libs provided at runtime
cudaPackages.gpus: Jetson should never build by default
cudaPackages.flags: don't build Jetson capabilities by default
cudaPackages: re-introduce filter for pre-existing CUDA redist packages in overrides
cudaPackages: only recurseIntoAttrs for the latest of each major version
cudaPackages.nvccCompatabilities: use GCC 10 through CUDA 11.5 to avoid a GLIBC incompatability
cudaPackages.cutensor: acquire libcublas through cudatoolkit prior to 11.4
cudaPackages.cuda_compat: mark as broken on aarch64-linux if not targeting Jetson
cudaPackages.cutensor_1_4: fix build
cudaPackages: adjust use of autoPatchelfIgnoreMissingDeps
cudaPackages.cuda_nvprof: remove unecessary override to add addOpenGLRunpath
cudaPackages: use getExe' to avoid patchelf warning about missing meta.mainProgram
cudaPackages: fix evaluation with Nix 2.3
cudaPackages: fix platform detection for Jetson/non-Jetson aarch64-linux
python3Packages.tensorrt: mark as broken if required packages are missing
Note: evaluating the name of the derivation will fail if tensorrt is not present,
which is why we wrap the value in `lib.optionalString`.
cudaPackages.flags.getNixSystem: add guard based on jetsonTargets
cudaPackages.cudnn: use explicit path to patchelf
cudaPackages.tensorrt: use explicit path to patchelf
