radeon_fence_count_emitted - get the count of emitted fences
: radeon device pointer : ring index the fence is associated with
Get the number of fences emitted on the requested ring (all asics). Returns the number of emitted fences on the ring. Used by the dynpm code to ring track activity.

| void radeon_fence_driver_fini | ( | struct radeon_device * | rdev | ) |
radeon_fence_driver_fini - tear down the fence driver for all possible rings.
: radeon device pointer
Tear down the fence driver for all possible rings (all asics).
Definition at line 855 of file radeon_fence.c.
| int radeon_fence_driver_init | ( | struct radeon_device * | rdev | ) |
radeon_fence_driver_init - init the fence driver for all possible rings.
: radeon device pointer
Init the fence driver for all possible rings (all asics). Not all asics have all rings, so each asic will only start the fence driver on the rings it has using radeon_fence_driver_start_ring(). Returns 0 for success.

radeon_fence_driver_start_ring - make the fence driver ready for use on the requested ring.
: radeon device pointer : ring index to start the fence driver on
Make the fence driver ready for processing (all asics). Not all asics have all rings, so each asic will only start the fence driver on the rings it has. Returns 0 for success, errors for failure.

| int radeon_fence_emit | ( | struct radeon_device * | rdev, |
| struct radeon_fence ** | fence, | ||

radeon_fence_emit - emit a fence on the requested ring
: radeon_device pointer : radeon fence object : ring index the fence is associated with
Emits a fence command on the requested ring (all asics). Returns 0 on success, -ENOMEM on failure.

| bool radeon_fence_need_sync | ( | struct radeon_fence * | fence, |

radeon_fence_need_sync - do we need a semaphore
: radeon fence object : which ring to check against
Check if the fence needs to be synced against another ring (all asics). If so, we need to emit a semaphore. Returns true if we need to sync with another ring, false if not.

radeon_fence_process - process a fence
: radeon_device pointer : ring index the fence is associated with
Checks the current fence value and wakes the fence queue if the sequence number has increased (all asics).

radeon_fence_ref - take a ref on a fence
: radeon fence object
Take a reference on a fence (all asics). Returns the fence.
Definition at line 642 of file radeon_fence.c.
| bool radeon_fence_signaled | ( | struct radeon_fence * | fence | ) |
radeon_fence_signaled - check if a fence has signaled
: radeon fence object
Check if the requested fence has signaled (all asics). Returns true if the fence has signaled or false if it has not.
Definition at line 244 of file radeon_fence.c.
| void radeon_fence_unref | ( | struct radeon_fence ** | fence | ) |
radeon_fence_unref - remove a ref on a fence
: radeon fence object
Remove a reference on a fence (all asics).

radeon_fence_wait - wait for a fence to signal
: radeon fence object : use interruptable sleep
Wait for the requested fence to signal (all asics). selects whether to use interruptable (true) or non-interruptable (false) sleep when waiting for the fence. Returns 0 if the fence has passed, error for all other cases.
Definition at line 383 of file radeon_fence.c.
| int radeon_fence_wait_any | ( | struct radeon_device * | rdev, |
| struct radeon_fence ** | fences, | ||

radeon_fence_wait_any - wait for a fence to signal on any ring
: radeon device pointer : radeon fence object(s) : use interruptable sleep
Wait for any requested fence to signal (all asics). Fence array is indexed by ring id. selects whether to use interruptable (true) or non-interruptable (false) sleep when waiting for the fences. Used by the suballocator. Returns 0 if any fence has passed, error for all other cases.

radeon_fence_wait_empty_locked - wait for all fences to signal
: radeon device pointer : ring index the fence is associated with
Wait for all fences on the requested ring to signal (all asics). Returns 0 if the fences have passed, error for all other cases. Caller must hold ring lock.
Definition at line 612 of file radeon_fence.c.
| int radeon_fence_wait_next_locked | ( | struct radeon_device * | rdev, |

radeon_fence_wait_next_locked - wait for the next fence to signal
: radeon device pointer : ring index the fence is associated with
Wait for the next fence on the requested ring to signal (all asics). Returns 0 if the next fence has passed, error for all other cases. Caller must hold ring lock.
