First real GPU implementation. Ring/PM4 frontend (ring_view,
ring_drain, pm4) drains the command processor; gpu_system owns the
threaded backend (DrainFence RPC + parker/fence helpers from M1) and
the MMIO-mapped register block (mmio_region).
Xenos shader frontend: ucode/{alu,control_flow,fetch,mod}.rs decode
the Xbox 360 microcode, translator.rs lowers it onto the WGSL
xenos_interp interpreter shader (shaders/xenos_interp.wgsl).
shader_metrics.rs counts decode/translate work.
Render state: draw_state, primitive, render_target_cache,
texture_cache, tiled_address (Xenos's swizzled tiled-memory layout),
xenos_constants (register field constants), edram (the 10 MiB EDRAM
model with MSAA), and resolve.rs (TILE_FLUSH copy-out — clear-resolve
plus bitwise-equivalent 32 bpp + 64 bpp paths landed). handle.rs
owns the typed GPU-resource handles the kernel hands out.

//! 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`].
