Class Documentation

◆ HPET::TimerConfigAndCapabilitiesRegister

union HPET::TimerConfigAndCapabilitiesRegister

Configuration register for comparators.

In addition to global configuration and value registers, every HPET timer comes with its own configuration register containing config used locally by the respective timer.

Class Members
struct TimerConfigAndCapabilitiesRegister	__unnamed__
uint64_t	value

◆ HPET::TimerFSBInterruptRouteRegister

union HPET::TimerFSBInterruptRouteRegister

Front-Side Bus Interrupt Message Route Register.

Currently, this register is not used by StuBS; it's definition is here for the sake of completeness.

Class Members
struct TimerFSBInterruptRouteRegister	__unnamed__
uint64_t	value
