//! Xenos GPU emulation for xenia-rs.
//!
//! Modules:
//! - [`pm4`]: packet format decoder + Type-3 opcode set.
//! - [`ring_view`]: ring-buffer bookkeeping (base/size/read/write pointers).
//! - [`register_file`]: 0x6000-entry register array backing the CP + state.
//! - [`gpu_system`]: top-level `GpuSystem` + PM4 executor running one packet
//!   per call (see the plan's P2 for the design rationale).
//!
//! Legacy module `ring_drain` and `command_processor` are retained while P3+
//! migrations finish; they will be removed once every caller is on
//! [`gpu_system::GpuSystem`].
