allocate_logical_cpuid

Name:Should use this API to allocate logical CPU IDs to keep nr_logical_cpuids* and cpuid_to_apicid[] synchronized.

Proto:static int allocate_logical_cpuid(int apicid)

Type:int

Parameter:

Type	Parameter	Name
int	apicid

2379

When i < The number of allocated logical CPU IDs. Since logical CPU IDs are allocated* contiguously, it equals to current allocated max logical CPU ID plus 1.* All allocated CPU IDs should be in the [0, nr_logical_cpuids) range, cycle

2380

If Used to store mapping between logical CPU IDs and APIC IDs.[i] == apicid Then Return i

2385

If The number of allocated logical CPU IDs. Since logical CPU IDs are allocated* contiguously, it equals to current allocated max logical CPU ID plus 1.* All allocated CPU IDs should be in the [0, nr_logical_cpuids) range, >= nr_cpu_ids Then

2386

WARN_ONCE(1, "APIC: NR_CPUS/possible_cpus limit of %u reached. Processor %d/0x%x and the rest are ignored.\n", nr_cpu_ids, The number of allocated logical CPU IDs.

Return -EINVAL

Used to store mapping between logical CPU IDs and APIC IDs.[The number of allocated logical CPU IDs. Since logical CPU IDs are allocated* contiguously, it equals to current allocated max logical CPU ID plus 1.* All allocated CPU IDs should be in the [0, nr_logical_cpuids) range,] = apicid

2393

Return The number of allocated logical CPU IDs. Since logical CPU IDs are allocated* contiguously, it equals to current allocated max logical CPU ID plus 1.* All allocated CPU IDs should be in the [0, nr_logical_cpuids) range,++
