Implementations

impl ApmInfo

pub fn has_mca_overflow_recovery(&self) -> bool

Is MCA overflow recovery available?

If set, indicates that MCA overflow conditions (MCi_STATUS[Overflow]=1) are not fatal; software may safely ignore such conditions. If clear, MCA overflow conditions require software to shut down the system.

Platforms

✅ AMD ❌ Intel (reserved=false)

pub fn has_succor(&self) -> bool

Has Software uncorrectable error containment and recovery capability?

The processor supports software containment of uncorrectable errors through context synchronizing data poisoning and deferred error interrupts.

Platforms

✅ AMD ❌ Intel (reserved=false)

pub fn has_hwa(&self) -> bool

Has Hardware assert supported?

Indicates support for MSRC001_10[DF:C0].

Platforms

✅ AMD ❌ Intel (reserved=false)

pub fn cpu_pwr_sample_time_ratio(&self) -> u32

Specifies the ratio of the compute unit power accumulator sample period to the TSC counter period.

Returns a value of 0 if not applicable for the system.

Platforms

✅ AMD ❌ Intel (reserved=0)

pub fn has_ts(&self) -> bool

Is Temperature Sensor available?

Platforms

✅ AMD ❌ Intel (reserved=false)

pub fn has_freq_id_ctrl(&self) -> bool

Frequency ID control.

Note

Function replaced by has_hw_pstate.

Platforms

✅ AMD ❌ Intel (reserved=false)

pub fn has_volt_id_ctrl(&self) -> bool

Voltage ID control.

Note

pub fn has_ro_effective_freq_iface(&self) -> bool

Has Read-only effective frequency interface?

Indicates presence of MSRC000_00E7 [Read-Only Max Performance Frequency Clock Count (MPerfReadOnly)] and MSRC000_00E8 [Read-Only Actual Performance Frequency Clock Count (APerfReadOnly)].

Platforms

✅ AMD ❌ Intel (reserved=false)

pub fn has_feedback_iface(&self) -> bool

Trait Implementations

impl Debug for ApmInfo

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

Formats the value using the given formatter.

impl PartialEq for ApmInfo

fn eq(&self, other: &ApmInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
