Subject: Phase 4: Portable Architecture Implementation

- Firmware Analyzer: Runtime firmware signature computation (CRC32, SHA256) and pattern-based RPC handler address discovery
- Dynamic RPC Dispatcher: Version-aware dispatch with native firmware handlers (550/560/570/580) and emulation fallback
- Hardware Architecture Layer: Turing, Ampere, Blackwell configs with BAR layouts, doorbell offsets, MSI-X vectors
- Driver Version Adaptation Layer: Feature detection per driver version
- Declarative YAML configs for hardware (turing/ampere/blackwell) and versions (550/560/570/580)
- Kernel unit tests for GSP emulation (gsp_emulation_test.c)
- Test infrastructure scripts (test_gsp_emu.sh, test_guest_driver.sh, test_cuda_workloads.sh, test_graphics_workloads.sh, test_windows_guest.sh, test_vgpu_stack.sh)
- Updated kernel Makefile with new source files
