Implementations

impl DomainControllerSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<DomainControllerEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn list_domains( &self, ___deadline: MonotonicInstant, ) -> Result<Vec<DomainInfo>, Error>

Lists info about each domain managed by the server.

The server is guaranteed to fill all fields within DomainInfo unless the field is explicitly marked as “Optional”.

pub fn get_max_frequency( &self, domain_id: u64, ___deadline: MonotonicInstant, ) -> Result<DomainControllerGetMaxFrequencyResult, Error>

Gets the index of the max frequency the CPU can run at.

max_frequency_index corresponds to the index of a frequency within this domain’s available_frequencies_hz list retrieved via [ListDomains].

If SetMaxFrequency or LeaseMaxFrequency has never been called, this will return the index that corresponds to the highest available frequency for this domain.

If domain_id is invalid, INVALID_ARGUMENTS is returned.

pub fn set_max_frequency( &self, domain_id: u64, frequency_index: u64, ___deadline: MonotonicInstant, ) -> Result<DomainControllerSetMaxFrequencyResult, Error>

Sets the max frequency the CPU can run at.

frequency_index must correspond to the index of a frequency within this domain’s available_frequencies_hz list retrieved via [ListDomains].

On products with Runtime Processor Power Management (RPPM), the CPU may briefly exceed max frequency if power limits allow.

If domain_id is invalid, INVALID_ARGUMENTS is returned. If frequency_index is invalid, INVALID_ARGUMENTS is returned.

pub fn clear_max_frequency( &self, domain_id: u64, ___deadline: MonotonicInstant, ) -> Result<DomainControllerClearMaxFrequencyResult, Error>

Clears the max frequency limit the CPU can run at.

If domain_id is invalid, INVALID_ARGUMENTS is returned.

pub fn get_min_frequency( &self, domain_id: u64, ___deadline: MonotonicInstant, ) -> Result<DomainControllerGetMinFrequencyResult, Error>

Gets the index of the min frequency the CPU can run at.

min_frequency_index corresponds to the index of a frequency within this domain’s available_frequencies_hz list retrieved via [ListDomains].

If no floor lease is currently active, this will return the index that corresponds to the lowest available frequency for this domain.

If domain_id is invalid, INVALID_ARGUMENTS is returned.

pub fn lease_max_frequency( &self, domain_id: u64, frequency_index: u64, lease_name: &str, ___deadline: MonotonicInstant, ) -> Result<DomainControllerLeaseMaxFrequencyResult, Error>

Acquires a ceiling lease on domain_id capping its maximum operating point at frequency_index.

Multiple clients may hold concurrent ceiling leases on the same domain; the server enforces the lowest maximum frequency (highest frequency_index) across all active leases. Each call creates an independent lease whose lifetime is governed solely by the returned lease_token handle; closing all handles to lease_token releases the lease.

lease_name is a human-readable label for diagnostics and Inspect only and is not required to be unique.

If domain_id or frequency_index is invalid, INVALID_ARGUMENTS is returned.

pub fn lease_min_frequency( &self, domain_id: u64, frequency_index: u64, lease_name: &str, ___deadline: MonotonicInstant, ) -> Result<DomainControllerLeaseMinFrequencyResult, Error>

Acquires a floor lease on domain_id raising its minimum operating point to frequency_index.

Multiple clients may hold concurrent floor leases on the same domain; the server enforces the highest minimum frequency (lowest frequency_index) across all active leases. Each call creates an independent lease whose lifetime is governed solely by the returned lease_token handle; closing all handles to lease_token releases the lease.

lease_name is a human-readable label for diagnostics and Inspect only and is not required to be unique.

If domain_id or frequency_index is invalid, INVALID_ARGUMENTS is returned.
