Struct raw_cpuid::CpuId

pub struct CpuId { /* fields omitted */ }

Main type used to query for information about the CPU we’re running on.

Implementations

impl CpuId

pub fn new() -> Self

Return new CPUID struct.

pub fn with_cpuid_fn(cpuid_fn: fn(_: u32, _: u32) -> CpuIdResult) -> Self

pub fn get_vendor_info(&self) -> Option<VendorInfo>

Return information about vendor. This is typically a ASCII readable string such as GenuineIntel for Intel CPUs or AuthenticAMD for AMD CPUs.

pub fn get_feature_info(&self) -> Option<FeatureInfo>

Query a set of features that are available on this CPU.

pub fn get_cache_info(&self) -> Option<CacheInfoIter>

Query basic information about caches. This will just return an index into a static table of cache descriptions (see CACHE_INFO_TABLE).

pub fn get_processor_serial(&self) -> Option<ProcessorSerial>

Retrieve serial number of processor.

pub fn get_cache_parameters(&self) -> Option<CacheParametersIter>

Retrieve more elaborate information about caches (as opposed to get_cache_info). This will tell us about associativity, set size, line size etc. for each level of the cache hierarchy.

pub fn get_monitor_mwait_info(&self) -> Option<MonitorMwaitInfo>

Information about how monitor/mwait works on this CPU.

pub fn get_thermal_power_info(&self) -> Option<ThermalPowerInfo>

Query information about thermal and power management features of the CPU.

pub fn get_extended_feature_info(&self) -> Option<ExtendedFeatures>

Find out about more features supported by this CPU.

pub fn get_direct_cache_access_info(&self) -> Option<DirectCacheAccessInfo>

Direct cache access info.

pub fn get_performance_monitoring_info(
    &self
) -> Option<PerformanceMonitoringInfo>

Info about performance monitoring (how many counters etc.).

pub fn get_extended_topology_info(&self) -> Option<ExtendedTopologyIter>

Information about topology (how many cores and what kind of cores).

pub fn get_extended_state_info(&self) -> Option<ExtendedStateInfo>

Information for saving/restoring extended register state.

pub fn get_rdt_monitoring_info(&self) -> Option<RdtMonitoringInfo>

Quality of service informations.

pub fn get_rdt_allocation_info(&self) -> Option<RdtAllocationInfo>

Quality of service enforcement information.

pub fn get_sgx_info(&self) -> Option<SgxInfo>

pub fn get_processor_trace_info(&self) -> Option<ProcessorTraceInfo>

Intel Processor Trace Enumeration Information.

pub fn get_tsc_info(&self) -> Option<TscInfo>

Time Stamp Counter/Core Crystal Clock Information.

pub fn get_processor_frequency_info(&self) -> Option<ProcessorFrequencyInfo>

Processor Frequency Information.

pub fn deterministic_address_translation_info(&self) -> Option<DatIter>

pub fn get_soc_vendor_info(&self) -> Option<SoCVendorInfo>

pub fn get_hypervisor_info(&self) -> Option<HypervisorInfo>

pub fn get_extended_function_info(&self) -> Option<ExtendedFunctionInfo>

Extended functionality of CPU described here (including more supported features). This also contains a more detailed CPU model identifier.

pub fn get_memory_encryption_info(&self) -> Option<MemoryEncryptionInfo>

Trait Implementations

impl Debug for CpuId

Vendor Info String, that can be for example “AuthenticAMD” or “GenuineIntel”.

Technical Background

The vendor info is a 12-byte (96 bit) long string stored in ebx, edx and ecx by the corresponding cpuid instruction.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CpuId

fn default() -> CpuId

Returns the “default value” for a type.
