When a process is first created, it occupies the "created" or "new" state. In this state, the process awaits admission to the "ready" state. Admission will be approved or delayed by a long-term, or admission, scheduler. Typically in most desktop computer systems, this admission will be approved automatically.
The state-components can be subdivided into two groups: user-state (state-items that are visible to the application, e.g. AVX-512 vector registers), and supervisor-state (state items that affect the application but are not directly user-visible, e.g. user-mode interrupt configuration).
Process state data define the status of a process when it is suspended, allowing the OS to restart it later. This always includes the content of general-purpose CPU registers, the CPU process status word, stack and frame pointers, etc. During context switch, the running process is stopped and another process runs. The kernel must stop the ...
Instruction set extensions that have been added to the x86 instruction set in order to support hardware virtualization.These extensions provide instructions for entering and leaving a virtualized execution context and for loading virtual-machine control structures (VMCSs), which hold the state of the guest and host, along with fields which control processor behavior within the virtual machine.
The CPU power states C0–C3 are defined as follows: C0 is the operating state. C1 (often known as Halt) is a state where the processor is not executing instructions, but can return to an executing state essentially instantaneously. All ACPI-conformant processors must support this power state.
While the machine state register found in the PowerPC architecture and the model-specific registers found in IA-32 and x86-64 architectures fulfill similar functions and the initialism "MSR" can refer to either, there are important differences that distinguish them. The machine state register, a single register, provides coarse-grained control ...

While microarchitectural state can change to suit the needs of each processor implementation in a processor family, binary compatibility among processors in a processor family requires a common architectural state. Architectural state naturally does not include state-less elements of a computer such as busses and computation units (e.g., the ALU).
