Operation

Assembler Syntax

RESET

Privilege

Supervisor only

RESET serializes earlier memory effects, applies the complete architectural warm-reset state to the executing logical processor, and resumes execution at BOOTPC.

RESET is supervisor-only and affects only the executing logical processor. Before the reset-state transition commits, all earlier memory effects and pending write-combining stores from that logical processor complete. No younger instruction effect becomes visible.

The complete register, hidden-state, and cache effects of the transition are defined under Event Reset and Context State. Instruction-fetch synchronization completes before the first instruction at BOOTPC is fetched.
