Field Documentation

◆ name

const char* name

Name of the queue.

Definition at line 155 of file rte_rcu_qsbr.h.

◆ flags

uint32_t flags

Flags to control API behaviors

Definition at line 157 of file rte_rcu_qsbr.h.

◆ size

uint32_t size

Number of entries in queue. Typically, this will be the same as the maximum number of entries supported in the lock free data structure. Data structures with unbounded number of entries is not supported currently.

Definition at line 159 of file rte_rcu_qsbr.h.

◆ esize

uint32_t esize

Size (in bytes) of each element in the defer queue. This has to be multiple of 4B.

Definition at line 166 of file rte_rcu_qsbr.h.

◆ trigger_reclaim_limit

uint32_t trigger_reclaim_limit

Trigger automatic reclamation after the defer queue has at least these many resources waiting. This auto reclamation is triggered in rte_rcu_qsbr_dq_enqueue API call. If this is greater than 'size', auto reclamation is not triggered. If this is set to 0, auto reclamation is triggered in every call to rte_rcu_qsbr_dq_enqueue API.

Definition at line 170 of file rte_rcu_qsbr.h.

◆ max_reclaim_size

uint32_t max_reclaim_size

When automatic reclamation is enabled, reclaim at the max these many resources. This should contain a valid value, if auto reclamation is on. Setting this to 'size' or greater will reclaim all possible resources currently on the defer queue.

Definition at line 180 of file rte_rcu_qsbr.h.

◆ free_fn

Function to call to free the resource.

Definition at line 186 of file rte_rcu_qsbr.h.

◆ p

void* p

Pointer passed to the free function. Typically, this is the pointer to the data structure to which the resource to free belongs. This can be NULL.

Definition at line 188 of file rte_rcu_qsbr.h.

◆ v

struct rte_rcu_qsbr* v

RCU QSBR variable to use for this defer queue

Definition at line 193 of file rte_rcu_qsbr.h.
