Pass Registration#

Macros to register a plugin’s passes.

Pass registration macros should be called at global scope (not within a function/method).

In order to avoid accidentally registering a pass twice, it is recommended to call registration macros from a *.cpp* file rather than a *.h* file.

Registration macros only add the pass to a list of passes to register. This is useful if you have passes defined in several **.cpp** files in your module. It is up to the module developer to call registerModulePasses() and deregisterModulePasses() to perform the actual registration.

See Passes for more pass related functionality.

Classes#

omni::graph::exec::unstable::IPassFactory: Factory interface for creating omni::graph::exec::unstable::IPass objects.
omni::graph::exec::unstable::IPassRegistry: Registry (database) of known omni::graph::exec::unstable::IPass objects.
omni::graph::exec::unstable::IPassTypeRegistry: omni::graph::exec::unstable::IPassFactory registry for a particular omni::graph::exec::unstable::PassType .

Macros#

OMNI_GRAPH_EXEC_REGISTER_GLOBAL_PASS: Adds an omni::graph::exec::unstable::IGlobalPass to a list to be registered as type omni::graph::exec::unstable::PassType::eGlobal at the module's (i.e.g DLL) startup.
OMNI_GRAPH_EXEC_REGISTER_PARTITION_PASS: Adds an omni::graph::exec::unstable::IPartitionPass to a list to be registered as type omni::graph::exec::unstable::PassType::ePartitioning at the module's (i.e.g DLL) startup.
OMNI_GRAPH_EXEC_REGISTER_PASS: Adds an omni::graph::exec::unstable::IPass to a list to be registered at the module's (i.e.g DLL) startup.
OMNI_GRAPH_EXEC_REGISTER_POPULATE_PASS: Adds an omni::graph::exec::unstable::IPopulatePass to a list to be registered as type omni::graph::exec::unstable::PassType::ePopulate at the module's (i.e.g DLL) startup.

Enumerations#

omni::graph::exec::unstable::PassType: Grouping type for different passes.

Functions#

void omni::graph::exec::unstable::deregisterModulePasses() noexcept: Deregisters the module's omni::graph::exec::unstable::IPass factories with IPassRegistry .
IPassRegistry * omni::graph::exec::unstable::getPassRegistry() noexcept: Returns the singleton pass registry.
void omni::graph::exec::unstable::registerModulePasses() noexcept: Registers the module's omni::graph::exec::unstable::IPass factories with omni::graph::exec::unstable::IPassRegistry .

Enumerations#

enum class omni::graph::exec::unstable::PassType#

Grouping type for different passes.

Graph transformation pass is registered with a given type and type can’t be changed after.

See Passes for more pass related functionality.

Note

We are not yet using all these states…expect changes.

Values:

enumerator ePopulate#: open-up graph types

enumerator ePartitioning#: change granularity of executions (including executors)

enumerator eGlobal#: pass is running over entire graph. no other passes can run now

enumerator eTypeInference#: resolve types

enumerator eOverrideExecution#: override compute methods, executors, etc

enumerator eScheduling#: memory access, pipeline stages, etc

enumerator eCount#: total number of known pass types

Functions#

inline void omni::graph::exec::unstable::deregisterModulePasses( ) noexcept#

Deregisters the module’s omni::graph::exec::unstable::IPass factories with IPassRegistry.

Failure to call this function may lead to crashes during program shutdown.

This function should be called in the module’s function registered with omni::core::OMNI_MODULE_ON_MODULE_UNLOAD(). This is usually called onUnload().

When developing a Kit extension, prefer calling OMNI_KIT_EXEC_CORE_ON_MODULE_UNLOAD() rather than this function.

See Pass Registration for more information about pass registration.

Thread Safety: This function is not thread safe.

inline IPassRegistry *omni::graph::exec::unstable::getPassRegistry( ) noexcept#

Returns the singleton pass registry.

Returns a singleton containing the pass registry.

See Pass Registration for more information about pass registration.

inline void omni::graph::exec::unstable::registerModulePasses( ) noexcept#

Registers the module’s omni::graph::exec::unstable::IPass factories with omni::graph::exec::unstable::IPassRegistry.

This function should be called in the module’s function registered with omni::core::OMNI_MODULE_ON_MODULE_STARTED(). This is usually called onStarted().

When developing a Kit extension, prefer calling OMNI_KIT_EXEC_CORE_ON_MODULE_STARTED() rather than this function.

See Pass Registration for more information about pass registration.

Thread Safety: This function is not thread safe.
