gem_scheduler_capability ()

unsigned
gem_scheduler_capability (int fd);

gem_scheduler_enabled ()

bool
gem_scheduler_enabled (int fd);

Feature test macro to query whether the driver has scheduling capability.

gem_scheduler_has_ctx_priority ()

bool
gem_scheduler_has_ctx_priority (int fd);

Feature test macro to query whether the driver supports assigning custom priorities to contexts from userspace.

gem_scheduler_has_static_priority ()

bool
gem_scheduler_has_static_priority (int fd);

Feature test macro to query whether the driver supports priority assigned from user space are statically mapping into 3 buckets.

gem_scheduler_has_preemption ()

bool
gem_scheduler_has_preemption (int fd);

Feature test macro to query whether the driver supports preempting active (currently executing on HW) workloads.

gem_scheduler_has_semaphores ()

bool
gem_scheduler_has_semaphores (int fd);

Feature test macro to query whether the driver supports using HW semaphores to schedule dependencies in parallel (using the HW to delay execution until ready to reduce latency).

gem_scheduler_has_engine_busy_stats ()

bool
gem_scheduler_has_engine_busy_stats (int fd);

Feature test macro to query whether the driver supports reporting accurate per-engine utilisation.

gem_scheduler_has_timeslicing ()

bool
gem_scheduler_has_timeslicing (int fd);

Feature test macro to query whether the driver supports using HW preemption to implement timeslicing of userspace batches. This allows userspace to implement micro-level scheduling within their own batches.

gem_scheduler_print_capability ()

void
gem_scheduler_print_capability (int fd);

Helper for pretty-printing scheduler capability.
