Struct nvml_wrapper::bitmasks::device::ThrottleReasons

pub struct ThrottleReasons { /* private fields */ }

Flags used to specify why a GPU is throttling.

Implementations

impl ThrottleReasons

pub const GPU_IDLE: Self = Self{bits: nvmlClocksThrottleReasonGpuIdle as u64,}

Nothing is running on the GPU.

This limiter may be removed in a future release.

pub const APPLICATIONS_CLOCKS_SETTING: Self = Self{bits: nvmlClocksThrottleReasonApplicationsClocksSetting as u64,}

GPU clocks are limited by the current applications clocks setting.

pub const USER_DEFINED_CLOCKS: Self = Self{bits: nvmlClocksThrottleReasonUserDefinedClocks as u64,}

👎 Deprecated:

Renamed to APPLICATIONS_CLOCKS_SETTING.

pub const SW_POWER_CAP: Self = Self{bits: nvmlClocksThrottleReasonSwPowerCap as u64,}

Software power scaling algorithm is reducing clocks.

pub const HW_SLOWDOWN: Self = Self{bits: nvmlClocksThrottleReasonHwSlowdown as u64,}

Hardware slowdown (reducing the core clocks by a factor of 2 or more) is engaged.

This is an indicator of:

• Temperature being too high
• External Power Brake Asseration being triggered (e.g. by the system power supply)
• Power draw being too high and Fast Trigger protection reducing the clocks

This may also be reported during powerstate or clock change, behavior that may be removed in a later release.

pub const SYNC_BOOST: Self = Self{bits: nvmlClocksThrottleReasonSyncBoost as u64,}

This GPU is being throttled by another GPU in its sync boost group.

Sync boost groups can be used to maximize performance per watt. All GPUs in a sync boost group will boost to the minimum possible clocks across the entire group. Look at the throttle reasons for other GPUs in the system to find out why this GPU is being held at lower clocks.

pub const SW_THERMAL_SLOWDOWN: Self = Self{bits: nvmlClocksThrottleReasonSwThermalSlowdown as u64,}

Software thermal slowdown.

This is an indicator of one or more of the following:

• The current GPU temperature is above the max GPU operating temperature
• The current memory temperature is above the max memory operating temperature

pub const HW_THERMAL_SLOWDOWN: Self = Self{bits: nvmlClocksThrottleReasonHwThermalSlowdown as u64,}

Hardware thermal slowdown is engaged, reducing core clocks by 2x or more.

This indicates that the temperature of the GPU is too high.

pub const HW_POWER_BRAKE_SLOWDOWN: Self = Self{bits: nvmlClocksThrottleReasonHwPowerBrakeSlowdown as u64,}

Hardware power brake slowdown is engaged, reducing core clocks by 2x or more.

This indicates that an external power brake assertion is being triggered, such as by the system power supply.

pub const DISPLAY_CLOCK_SETTING: Self = Self{bits: nvmlClocksThrottleReasonDisplayClockSetting as u64,}

GPU clocks are limited by the current setting of display clocks.

pub const NONE: Self = Self{bits: nvmlClocksThrottleReasonNone as u64,}

Clocks are as high as possible and are not being throttled.

pub const fn empty() -> Self

Returns an empty set of flags.

pub const fn all() -> Self

Returns the set containing all flags.

pub const fn bits(&self) -> u64

Returns the raw value of the flags currently stored.

pub const fn from_bits(bits: u64) -> Option<Self>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u64) -> Self

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u64) -> Self

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

Safety

The caller of the bitflags! macro can chose to allow or disallow extra bits for their bitflags type.

The caller of from_bits_unchecked() has to ensure that all bits correspond to a defined flag or that extra bits are valid for this bitflags type.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: Self) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: Self) -> bool

Returns true if all of the flags in other are contained within self.

pub fn insert(&mut self, other: Self)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: Self)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: Self)

Toggles the specified flags in-place.

pub fn set(&mut self, other: Self, value: bool)

Inserts or removes the specified flags depending on the passed value.

pub const fn intersection(self, other: Self) -> Self

Returns the intersection between the flags in self and other.

Specifically, the returned set contains only the flags which are present in both self and other.

This is equivalent to using the & operator (e.g. ops::BitAnd), as in flags & other.

pub const fn union(self, other: Self) -> Self

Returns the union of between the flags in self and other.

Specifically, the returned set contains all flags which are present in either self or other, including any which are present in both (see Self::symmetric_difference if that is undesirable).

This is equivalent to using the | operator (e.g. ops::BitOr), as in flags | other.

pub const fn difference(self, other: Self) -> Self

Returns the difference between the flags in self and other.

Specifically, the returned set contains all flags present in self, except for the ones present in other.

It is also conceptually equivalent to the “bit-clear” operation: flags & !other (and this syntax is also supported).

This is equivalent to using the - operator (e.g. ops::Sub), as in flags - other.

pub const fn symmetric_difference(self, other: Self) -> Self

Returns the symmetric difference between the flags in self and other.

Specifically, the returned set contains the flags present which are present in self or other, but that are not present in both. Equivalently, it contains the flags present in exactly one of the sets self and other.

This is equivalent to using the ^ operator (e.g. ops::BitXor), as in flags ^ other.

pub const fn complement(self) -> Self

Returns the complement of this set of flags.

Specifically, the returned set contains all the flags which are not set in self, but which are allowed for this type.

Alternatively, it can be thought of as the set difference between Self::all() and self (e.g. Self::all() - self)

This is equivalent to using the ! operator (e.g. ops::Not), as in !flags.
