Structs

Section titled “Structs”

scheduler_group

Section titled “scheduler_group”
struct scheduler_group (6 fields) source

per-group: cluster of CPUs in one domain node

§ struct cpu_mask cpus

CPUs in this group (copy of topology_node->cpus)

§ struct cpu_mask idle

idle map (mirrors topology_node->idle)

§ uint64_t load

aggregated load metric for group (normalized)

§ uint32_t capacity

capacity hint for the group (sum of CPU capacities)

§ int32_t parent_index

index into sched_domain->groups for parent group (-1 none)

§ int32_t topo_index

index of topology_node used to build this group

scheduler_domain

struct scheduler_domain (4 fields) source

per-domain: list of groups at same level

§ enum topology_level level

which topology level this domain maps to

§ struct scheduler_group *groups cc_counted_by(ngroups)
§ size_t ngroups
§ struct scheduler_domain *parent
