This change ensures that the update-ldcache hook is created in a manner
consistent with other nvidia-ctk hooks ensuring that a full path is
used.
Without this change the update-ldcache hook on Tegra-based sytems had an
invalid path.

If this is not done, the default config which sets the nvidia-ctk.path
option as "nvidia-ctk" will result in an invalid OCI spec if a hook is
injected. This change ensures that the path used is always an absolute
path as required by the hook spec.

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 adds the discovery of DRM devices associated with requested
devices. This means that the /dev/dri/card* and /dev/dri/renderD*
devices associated with each requested NVIDIA GPU are injected into
the container and that the /dev/dri/by-path symlinks associated with
these devices are created in the container.

This change adds support for filtering entities by specifying a filter.
This can be used, for example, to check whether a mount or device
has a particular property and removing it from the set of discovered
entities if it does not.

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 root member to the mounts type that is used to
perform most of the lookups for files and devices. This allows
for consistent handling of relative paths.

This change adds a charDevices discoverer and using this
for CSV, GDS, and MOFED discovery. Internally the discoverer
is a "mounts" discoverer with a charDevice locator.
Signed-off-by: Evan Lezar <elezar@nvidia.com>
Instead of creating a set of discoverers per file, this change creates
a discoverer per type by first concatenating the mount specifications
from all files. This will allow all device nodes, for example, to
be treated as a single device.

This adds a Relative function to the Locator interface and uses
this to determine the host and container paths for located files
(and devices). This ensures that the root (e.g. the nvidia driver
root) is stripped from the container path.

This change updates the create-symlinks hook to also create symlinks for
libcuda.so, libGLX_indirect.so.0, and libnvidia-opticalflow.so

This change adds a DefaultExecutableDir = /usr/bin constant that is used
to construct default paths for executables instead of specifying these
explicitly.

This change adds a cache to the mounts type. This means that if called to get
a list of folders, for example, the result is reused instead of recalculated.
This also avoids duplicate logging.

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.
Signed-off-by: Evan Lezar <elezar@nvidia.com>
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 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.
