This helper library contains functions used for getting information on currently used hardware submission method. Different generations of hardware support different submission backends, currently we're distinguishing 3 different methods: legacy ringbuffer submission, execlists, GuC submission.
void
gem_submission_print_method (int fd);
Helper for pretty-printing currently used submission method
bool gem_engine_has_mutable_submission (int fd,unsigned int engine);
Returns boolean value if the engine allows batch modifications post execbuf.
bool gem_class_has_mutable_submission (int fd,int class);
Returns boolean value if the engine class allows batch modifications post execbuf.
bool gem_engine_has_cmdparser (int i915,const intel_ctx_cfg_t *cfg,unsigned int engine);
Returns true if the given engine has a command parser
unsigned int gem_submission_measure (int i915,const intel_ctx_cfg_t *cfg,unsigned int engine);
void
gem_test_all_engines (int fd);
Execute a nop batch on the engine specified, or ALL_ENGINES for all, and check it executes.
bool
gem_has_relocations (int fd);
Feature test macro to query whether kernel allows for generation to use relocations.
bool
gem_allows_obj_alignment (int fd);
Check does i915 driver allows setting object alignment in exec object to handle in kernel and adjust object offset accordingly.
