docs: rewrite testing guidelines — accurate, comprehensive, actionable
...
Major rewrite of TESTING_GUIDELINES.md based on audit of actual codebase:
Key corrections:
- uos-target.py is a target-definition validator, NOT a test orchestrator
- No in-kernel test harness exists (only inline smoke tests)
- No CI boot testing (only build verification)
- No kernel code coverage (only tool-level coverage)
- uos-cover tools ARE operational with 11 test files
New content:
- Current state vs planned state clearly separated
- Host-side testing (pytest) documented with examples
- Firmware testing with uos-check.sh documented
- Code coverage workflow with uos-cover tools
- Test environment requirements
- Risk-based test prioritization (P0-P3)
- Test categories (smoke, functional, regression, performance, stress, security)
- 5-phase roadmap: CI boot tests → test harness → coverage in CI → MC/DC → perf
- Appendices with file locations, CI status, common commands
Document now accurately reflects what exists and provides actionable guidance.

- PikeOS-style flat 4GB MMU section map + proper enable (unblocked device MMIO)
- guest.h MAX_GUEST_IMAGE_SIZE 256MB->16MB (BSS was 259MB)
- C/C++ linkage fixes, duplicate-virtio_net_init, MMIO access-size handling
Phase D (PikeOS ARMv7 Microkernel Port):
- D-1: Per-VM address spaces — cloned pgdirs, ASID-tagged TLB, 4K page walker,
isolation PASSED (two guests, same VA->different PAs), guest fault recovery
- D-2: IRQ dispatch backbone — 1024-slot dispatch table, real GICv2 hardware
(GICD_CTLR/GICC_CTLR/GICC_PMR/GICC_IAR/GICC_EOIR), arm_irq_handler wired
- D-3: Time subsystem — CNTVCT ns-since-boot, CNTP periodic ticker via D-2
- D-4: KDEV framework — linker-section driver registration, uos_kdev_init_all,
name lookup
- D-5: VFP/NEON — lazy enable (undef trap->CPACR+FPEXC.EN), FPEXC=0x40000000
- D-6: SMP — per-CPU state, MPIDR, IPI/SGI framework (reschedule+TLB flush)
All uos_ naming (PikeOS p4_ convention adapted). Compiles -Werror freestanding C++17.
