◆ ongoing_term_reqs

odp_atomic_u32_t core_map_t::ongoing_term_reqs[ODP_THREAD_COUNT_MAX]

Number of ongoing TERM_THREAD_REQ operations per thread

Definition at line 69 of file em_core_types.h.

◆ proc_tid_stat_paths

char core_map_t::proc_tid_stat_paths[EM_MAX_CORES][32]

Store file paths to each EM-core's /proc/[tid]/stat file so that the paths don't have to be generated each time.

Definition at line 125 of file em_core_types.h.

◆ rwlock

odp_rwlock_t core_map_t::rwlock

Read-write lock for the 'rwlocked'-struct below.

Multiple readers of core-map data are allowed at the same time, but only one writer. The only two scenarios where the lock is taken for writes are adding an EM-core via em_init_local/core() and removing an EM-core via em_term_local/core() - thus taking the lock for reads in control operations is not time crtitical since add/rem core operations can afford to wait.

This lock is also used to block EM-core adds or rems when an internal control operation is under way that needs info about the cores available and sends control events to them - cores can not be allowed to be removed in the middle of this.

Definition at line 86 of file em_core_types.h.

Definition at line 109 of file em_core_types.h.

◆ tids

pid_t core_map_t::tids[EM_MAX_CORES]

Thread ids of EM-cores (worker and control)

Definition at line 114 of file em_core_types.h.

◆ worker_core_count
