This change allows nvcdi.New to return an error in addition to the
constructed library instead of panicing.

CDI generation modes such as management and wsl don't require
NVML. This change removes the top-level instantiation of nvmllib
and replaces it with an instanitation in the nvml CDI spec generation
code.

This change generates device folder permission hooks per device instead of
at a spec level. This ensures that the hook is not injected for a device that
does not have any nested device nodes.

These changes add a wsl discovery mode to the nvidia-ctk cdi generate command.
If wsl mode is enabled, the driver store for the available devices is used as
the source for discovered entities.

This change adds --discovery-mode flag to the nvidia-ctk cdi generate
command and plumbs this through to the CDI API.
Signed-off-by: Evan Lezar <elezar@nvidia.com>
This change adds an nvcdi package that exposes a basic API for
CDI spec generation. This is used from the nvidia-ctk cdi generate
command and can be consumed by DRA implementations and the device plugin.

This makes the intent of the command line argument clearer since this
relates specifically to the root where the NVIDIA driver is installed.

This change uses the `index` mode for the --device-name-strategy when
generating CDI specifications by default. This generates device names
such as nvidia.com/gpu=0 or nvidia.com/gpu=1:0 by default.
Note that this requires a CDI spec version of 0.5.0 and for consumers
(e.g. podman) that are only compatible with older versions one of the
other stragegies (`type-index` or `uuid`) should be used instead to
generate a v0.3.0 or v0.4.0 specification.

This change adds a --create-all mode to the create-dev-char-symlinks hook.
This mode creates all POSSIBLE symlinks to device nodes for regular and cap
devices. With the number of GPUs inferred from the PCI device information.

This change adds a --watch option to the create-dev-char-symlinks hook. This
installs an fsnotify watcher that creates symlinks for ADDED device nodes under
/dev/char.

This change adds an nvidia-ctk hook create-dev-char-symlinks
subcommand that creates symlinks to device nodes (as required by
systemd) under /dev/char.

This change adds a --device-name-strategy flag for generating a CDI
specificaion. This allows a CDI spec to be generated with the following
names used for device:
* type-index: gpu0 and mig0:1
* index: 0 and 0:1
* uuid: GPU and MIG UUIDs
Note that the use of 'index' generates a v0.5.0 CDI specification since
this relaxes the restriction on the device names.

This change uses functionality from the CDI package to determine
the minimum required CDI spec version. This allows for a spec with
the widest compatibility to be specified.

This change implements the discovery of versioned driver libaries
by reusing the mounts and update ldcache discoverers use for, for example,
CVS file discovery. This allows the container paths to be correctly generated
without requiring specific manipulation.

This change adds an --nvidia-ctk-path to the nvidia-ctk cdi generate
command. This ensures that the executable path for the generated
hooks can be specified consistently.
Since the NVIDIA Container Runtime already allows for the executable
path to be specified in the config the utility code to update the
LDCache and create other nvidia-ctk hooks are also updated.

This change refactors the generation of CDI specifications
to use discoverers and generate the CDI specifications from these
discoverers. This allows for better reuse.

This change replaces the `--json` flag of the nvidia-ctk cdi generate
command with a --format flag that accepts a string format of either
json or yaml.

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
noexec flag to allow these to function in rootless mode with podman.

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)

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 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 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 adds version output to the nvidia-continer-runtime,
nvidia-container-toolkit, and nvidia-ctk CLIs. The same version

The construction of the version string mirrors what is done in runc.
