This change extends the support for multiple envvars when
specifying swarm resources to consider ALL of the specified
environment variables instead of the first match.

This change generates one or more createContainer hooks for ensuring
that subfolders in /dev have the required permissions in the container.
As an example, a user requires read permissions to the /dev/nvidia-caps
in addition to including the specific caps devices under this folder.

This change adds an nvidia-ctk hook chmod command that can be used
to update the permissions for paths in the container.
This prepends the container root to the paths to allow these to be
updated by runtime executables.

This change ensures that the CDI spec mounts the ipc sockets with the

This change updates the docker config update for simplicitly.
This also allows for the API to match the crio update code.

This adds support for updating crio configs (instead of installing hooks)
and adds crio support to the nvidia-ctk runtime configure command.

This change includes meta devices (e.g. /dev/nvidiactl) in the
generated CDI spec. Missing device nodes are ignored.

This change generates a v0.4.0 CDI spec instead of a v0.5.0 spec.
This allows older versions of podman, for example, to be used.
This requires that the device names do not start on a numeric character
and that the HostPath for a device is unspecified.

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

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

This change adds version output to the nvidia-continer-runtime,

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"

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

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

If "legacy" is selected, the existing NVIDIA Container Runtime hooks is
discovered and injected into the OCI spec.
