inline

Member Function Documentation

void VirtualCpu::dprintf ( const char *  format,   ...  )

inlineprivate

long long VirtualCpu::get_tsc_off ( CpuMessage &  msg )

inlineprivate

Return current TSC offset.

Works around destroyed value in msg.cpu->tsc_off when we want to change the TSC offset.

void VirtualCpu::got_event ( unsigned  value )

inlineprivate

We received an asynchronous event.

As code runs in many threads, state updates have to be atomic!

try to claim the SIPI field, if it is empty, we are waiting for a SIPI. If it fails, somebody else was faster and we do not wakeup the client.

void VirtualCpu::GP0 ( CpuMessage &  msg )

inlineprivate

void VirtualCpu::handle_cpu_init ( CpuMessage &  msg, bool  reset  )

inlineprivate

bool VirtualCpu::handle_cpuid ( CpuMessage &  msg )

inlineprivate

void VirtualCpu::handle_wrmsr ( CpuMessage &  msg )

inlineprivate

void VirtualCpu::prioritize_events ( CpuMessage &  msg )

inlineprivate

Prioritize different events.

Returns the events to clear.

bool VirtualCpu::receive ( MessageMem &  msg )

inline

Forward MEM requests to the motherboard.

bool VirtualCpu::receive ( MessageMemRegion &  msg )

inline

bool VirtualCpu::receive ( CpuEvent &  msg )
