t_Capture — TFT.OpenGPU.Stack.Module

1. Module Intent#

The TFT.OpenGPU.Stack.Module defines a three‑layer GPU substrate architecture built around TFT dimensional primitives.
It provides an open alternative to closed GPU primitive ecosystems and establishes a substrate‑first model for remote rendering, Cloud PC tiering, and GPU virtualization.

This capture document records the module’s structural intent, primitive surfaces, and alignment with RTT.

2. Structural Overview#

The module expresses three aligned views:

A — TFT.OpenGPU.Stack#

A functional description of the stack:

• Substrate: TFT dimensional primitives and resonance operators.
• Rendering: Open rendering layer (Vulkan/WebGPU/custom).
• Execution: AMD-friendly GPU primitives (ROCm/VCE/SR‑IOV).

B — TFT.Substrate.Execution.Rendering#

A structural decomposition:

• Substrate Layer: Hidden view, dimensional intent, wrapped draw operators.
• Rendering Layer: Scene/viewport abstraction, materials, meshes, lights.
• Execution Layer: Kernels, tiles, warps, GPU cycles, VRAM, virtualization primitives.

C — OpenSubstrate GPU Stack (OSGS)#

A market-facing description:

• Vendor-neutral, AMD-first.
• TFT primitives as the differentiator.
• Cloud PC tiering via vGPU slices.
• Remote desktops/apps via TFT primitive streams.

3. RTT Alignment#

Resonance (rtt=1)#

The module operates in a single-resonance layer.
All primitives, operators, and mappings remain within one coherent RTT surface.

Coherence (declared)#

Primitive mappings between substrate, rendering, and execution layers are explicitly declared.
No implicit cross-layer drift is permitted.

Drift (bounded)#

Drift is allowed only where substrate primitives reinterpret execution or rendering primitives.
All reinterpretations remain structurally bounded.

Paradox (structural)#

The module uses structural paradox via the Inverted Star pattern:

• Hidden view: TFT substrate primitives.
• Visible view: Rendering + execution primitives.
• Inversion: Remote reconstruction of dimensional intent.

4. Primitive Surfaces#

Substrate Primitives (TFT)#

• Dimensional operators
• Wrapped draw intent
• Substrate cycles
• Viewport substrates
• Primitive streams for remoting

Rendering Primitives (Open Layer)#

• Scene graph
• Materials
• Meshes
• Lights
• Camera/viewports
• GPU-native reconstruction

Execution Primitives (AMD-friendly)#

• Kernels
• Tiles
• Warps
• GPU cycles
• VRAM allocation
• SR‑IOV/vGPU slices
• DMA-safe surfaces

5. RDP Integration Surface#

The module defines a clean insertion point for TFT primitives inside RDP:

• RDPEGFX codec extension
• Custom virtual channel
• Primitive stream transport
• GPU-native reconstruction on endpoint

RDP retains:

• TLS
• CredSSP
• NLA
• reliability
• ordering
• session setup

TFT provides:

• dimensional intent
• substrate primitives
• GPU reconstruction semantics

6. Cloud PC Tiering#

Cloud PC tiers map directly to vGPU slices:

• Tier → vGPU cycles
• Tier → VRAM allocation
• Tier → scheduling priority
• Tier → reconstruction fidelity

Even minimal tiers achieve smooth remote rendering via TFT primitives.

7. AMD Partnership Surface#

The module defines a partnership surface for AMD:

• Open primitive layer
• Vendor-neutral substrate
• ROCm/VCE alignment
• SR‑IOV/vGPU integration
• Cloud PC differentiation
• Remote rendering advantage
• Alternative to NVIDIA’s closed primitive ecosystem

8. Canonical Capture Summary#

The TFT.OpenGPU.Stack.Module establishes:

• A substrate-first GPU architecture
• A dimensional primitive layer
• An open rendering surface
• An AMD-friendly execution layer
• A Cloud PC tiering model
• A substrate-aware RDP extension
