Enumeration Type Documentation

vregion_mem_type

enum vregion_mem_type

Memory types for virtual region allocations.

Used to specify the type of memory allocation within a virtual region.

Note

• interim: allocation that can be freed i.e. get/set large config, kcontrols.
• lifetime: allocation that cannot be freed i.e. init data, pipeline data.

Enumerator
VREGION_MEM_TYPE_INTERIM
VREGION_MEM_TYPE_LIFETIME
