Implementations

impl Waet

pub fn get(acpi_tables: &AcpiTables) -> Option<&Waet>

Finds the WAET in the given AcpiTables and returns a reference to it.

pub fn rtc_good(&self) -> bool

Returns whether the RTC has been enhanced not to require acknowledgment after it asserts an interrupt.

If this returns true, an interrupt handler can bypass reading the RTC register to unlatch the pending interrupt.

pub fn acpi_pm_timer_good(&self) -> bool

Returns whether the ACPI PM timer has been enhanced not to require multiple reads.

If this returns true, only a single read of the ACPI PM timer is necessary to obtain a reliable value from it.
