Detailed Description

ThreadContext is the external interface to all thread state for anything outside of the CPU.

It provides all accessor methods to state that might be needed by external objects, ranging from register values to things such as kernel stats. It is an abstract base class; the CPU can create its own ThreadContext by deriving from it.

The ThreadContext is slightly different than the ExecContext. The ThreadContext provides access to an individual thread's state; an ExecContext provides ISA access to the CPU (meaning it is implicitly multithreaded on SMT systems). Additionally the ThreadState is an abstract class that exactly defines the interface; the ExecContext is a more implicit interface that must be implemented so that the ISA can access whatever state it needs.

Member Enumeration Documentation

◆ Status

enum gem5::ThreadContext::Status

Enumerator
Active	Running. Instructions should be executed only when the context is in this state.
Suspended	Temporarily inactive. Entered while waiting for synchronization, etc.
Halting	Trying to exit and waiting for an event to completely exit. Entered when target executes an exit syscall.
Halted	Permanently shut down. Entered when target executes m5exit pseudo-instruction. When all contexts enter this state, the simulation will terminate.

Flat register interfaces.

Some architectures have different registers visible in different modes. Such architectures "flatten" a register (see flattenRegId()) to map it into the gem5 register file. This interface provides a flat interface to the underlying register file, which allows for example serialization code to access all registers.
