Proto:static void add_rmid_to_limbo(struct rmid_entry *entry)

Type:void

Parameter:

struct rmid_entry *	entry

r = rdt_resources_all[RDT_RESOURCE_L3]

174

busy = 0

175

cpu = get_cpu()

177

If pumask_test_cpu - test for a cpu in a cpumask*@cpu: cpu number (< nr_cpu_ids)*@cpumask: the cpumask pointer* Returns 1 if @cpu is set in @cpumask, else returns 0 Then

178

val = __rmid_read(rmid, Event IDs are used to program IA32_QM_EVTSEL before reading event* counter from IA32_QM_CTR)

179

If val <= This is the threshold cache occupancy at which we will consider an* RMID available for re-allocation. Then Continue

187

If Not has_busy_rmid(r, d) Then cqm_setup_limbo_handler(d, CQM_LIMBOCHECK_INTERVAL)

189

Atomically set a bit in memory

190

busy++

192

194

If busy Then @rmid_limbo_count count of currently unused but (potentially)* dirty RMIDs.* This counts RMIDs that no one is currently using but that* may have a occupancy value > intel_cqm_threshold. User can change* the threshold occupancy value.++

196

Else list_add_tail - add a new entry*@new: new entry to be added*@head: list head to add it before* Insert a new entry before the specified head.* This is useful for implementing queues.
