This change allows the swarm-resource config option to specify a
comma-separated list of environment variables instead of a single
environment variable.
The first environment variable matched is considered and other
environment variables are ignored.

This change adds functionality to generate CDI specifications
for all devices detected on the system. A specification containing
all GPUs and MIG devices is generated. All libraries on the host
ldcache that have an NVIDIA Driver Version suffix are included as
are the required binaries and IPC sockets.
A hook (based on the nvidia-ctk hook subcommand) to update the ldcache
in the container for the libraries being injected is also added to the
CDI specificiation.

This change allows the NVIDIA Container Runtime to inject vulkan
loaders and libraries by modifying the OCI runtime specification.
This allows vulkan applications to run in containers without
additional modifications.

This change adds a modifier to that injects the tegra platform files
* /etc/nv_tegra_release
* /sys/devices/soc0/family
allowing these files to be used for platform detection in a containerized
context such as the GPU device plugin.

This change improves the error message when invoking the NVIDIA
Runtime Hook in non-legacy mode. This should guide users to specifying
the --runtime=nvidia flag when using docker.

This change adds a `runtime configure` command to the nvidia-ctk CLI. This
command is currently limited to configuring the docker config on the
system by modifying the daemon.json config file associated with docker.

This change renames the nvidia-container-toolkit executable

This change creates GDS and MOFED modifiers and adds them to the

This change uses modifier compositioning and the discoverModifier to
refactor the existing CSV modifier.
This change adds a discoverModifier to the internal/modifier package and
refactors the CSV modifier to use this abstraction.

This change adds version output to the nvidia-continer-runtime,
nvidia-container-toolkit, and nvidia-ctk CLIs. The same version
is used in all cases and includes a version string and a git
revision if set.
The construction of the version string mirrors what is done in runc.

These changes replace the nvidia-container-runtime config options
experimental and discover-mode with a single mode config option.
Note that mode is now a string with a default value of "auto"
and a mode value of "legacy" is equivalent to experimental == false.

This also removes a test that invokes nvidia-container-runtime run --bundle

This change adds a DefaultExecutableDir = /usr/bin constant that is used

This change adds a discovered hook for updating the ldcache as a container-create
hook. The mounts from a discoverer are inspected to determine the folders that must
be added to the cache using the nvidia-ctk hook update-ldcache command.
This is added to the "csv" discovery mode for the experimental runtime.

This change adds an 'auto' discover mode that attempts to select the correct mode
for a given platform. This currently attempts to detect whether the platform is a
Tegra-based system in which case the 'csv' discover mode is used. The 'legacy'
discover mode is used as the fallback.

This change ensures that by default, the CSV discovery only considers the base CSV
files (l4t.csv, drivers.csv, devices.csv) and skips the rest unless the
NVIDIA_REQUIRE_JETPACK is set to "csv-mounts=all", in which case, all CSV files in the
specified folder are considered.

This change adds support for a "csv" discovery mode to the experimental runtime.
If this is set with experimental = true, a CSV-based discovery of devices and
mounts are used to define the modifications required to the OCI spec. The edits
are expressed as CDI ContainerEdits.

This change enables the experimental mode of the NVIDIA Container Runtime. If
enabled, the nvidia-container-runtime.discover-mode config option is
queried to determine how required OCI spec modifications should be defined.
If "legacy" is selected, the existing NVIDIA Container Runtime hooks is
discovered and injected into the OCI spec.

This change moves the code defining the insertion of the nvidia-container-runtime

This change imports the modifying runtime abstraction from the
experimental branch. This encapsulates the checks for whether
modification is required, and forwards the loaded spec to

This change adds support for a supported-driver-capabilities config
