chore: sync all pending changes — kirigami platform headers, cookbook fix, docs, patches

Kirigami: remove stub .cpp, add Qt platform integration headers for
QML gate. Matches KDE src/pattern for direct header-only builds.

Cookbook: add --no-backup-if-mismatch to patch invocation (fetch.rs).

Kernel: consolidate patch chain, add debug-scheme-serial-fix.

Docs: archive old audit reports, add CHANGELOG and hardware validation
matrix. Update AGENTS.md with Linux reference source policy.

Scripts: add test-network-qemu.sh, test-storage-qemu.sh.

.gitignore: add local/reference/ exclusion.

+## LINUX REFERENCE SOURCE POLICY
+
+`local/reference/linux-7.0/` (or later) contains a full Linux kernel source tree for
+cross-referencing driver behavior, hardware initialization sequences, register definitions,
+and error handling patterns.
+
+**Rules:**
+- **NEVER delete** the reference tree. It is gitignored but permanent.
+- **ALWAYS consult** the Linux source when building or fixing drivers, daemons, or any subsystem
+  that has a Linux counterpart (audio/HDA, GPU/DRM, networking, USB, PCI, ACPI, input, storage,
+  filesystems, scheduler, memory management).
+- **Update** the reference tree when a new stable Linux version is needed:
+  `git -C local/reference/linux-7.0 fetch --depth=1 origin tag:v7.x --force`
+- The reference tree is read-only for consultation purposes. No modifications.
+- Location: `local/reference/` is gitignored. It survives `make clean` and `make distclean`.
+
 ## DURABILITY POLICY

+# Red Bear OS — Driver & Hardware Improvement Plan
+
+**Date**: 2026-05-04
+**Status**: In Progress — Phase 0 ✅, Phase 1 ✅, Phase 2 ✅, Phase 3 ✅, Phase 4 partial, Phase 5 ✅, Addendum A added
+**Authority**: This plan defines improvements for subsystems NOT covered by existing plans. For ACPI, USB, IRQ/PCI, GPU/DRM, Bluetooth, and Wi-Fi, defer to their respective plans. This plan fills the storage, network, and audio gaps and adds cross-cutting concerns.
+
+**Source of truth**: Linux kernel 7.0 (`local/reference/linux-7.0/`). When in doubt, Linux behavior is authoritative. Every task includes the specific Linux source file and function to reference.
+
+---
+
+## Relationship to Existing Plans
+
+This plan is **subordinate** to the following plans for their respective subsystems. Tasks here do not duplicate, override, or conflict with them:
+
+| Plan Document | Subsystem | Status |
+|---------------|-----------|--------|
+| `ACPI-IMPROVEMENT-PLAN.md` | ACPI sleep, thermal, EC, power states | Active |
+| `IRQ-AND-LOWLEVEL-CONTROLLERS-ENHANCEMENT-PLAN.md` | PCI IRQ, MSI-X, IOMMU, controllers | Active |
+| `USB-IMPLEMENTATION-PLAN.md` | xHCI, EHCI, device lifecycle | Active |
+| `DRM-MODERNIZATION-EXECUTION-PLAN.md` | GPU/DRM display, KMS, Mesa | Active |
+| `BLUETOOTH-IMPLEMENTATION-PLAN.md` | BT host/controller | Active |
+| `WIFI-IMPLEMENTATION-PLAN.md` | Wi-Fi control plane | Active |
+| `CONSOLE-TO-KDE-DESKTOP-PLAN.md` | Desktop/KDE path | Active |
+
+**New coverage by this plan**: Storage drivers (AHCI, NVMe), Network drivers (e1000, r8168), Audio drivers (HDA, AC97), Input completeness (PS/2, HID), and cross-cutting driver quality (error handling, logging, lifecycle).
+
+---
+
+## Validation States
+
+All tasks use these validation levels, consistent with existing plans:
+
+- **builds** — compiles without error against the target toolchain
+- **enumerates** — discovers hardware and reports it through scheme interfaces
+- **usable** — works in a bounded real scenario (QEMU or bare metal)
+- **validated** — passes explicit acceptance tests with captured evidence
+- **hardware-validated** — proven on real bare metal, not just QEMU
+
+---
+
+## Phase 0: Cross-Cutting Driver Quality (Weeks 1-2)
+
+These improvements apply to ALL drivers and must be done first to establish the quality baseline for subsequent phases.
+
+### T0.1: Driver Error Handling Audit
+
+**Problem**: Many drivers use `unwrap()`/`expect()` on hardware operations (I/O port reads, MMIO, PCI config space). Hardware failures produce panics instead of graceful degradation.
+
+**Task**: Audit all drivers in `recipes/core/base/source/drivers/` and `local/recipes/drivers/` for:
+1. `unwrap()`/`expect()` on hardware I/O — replace with proper `Result` propagation
+2. Missing error logging for hardware failures — add `log::error!()` before error returns
+3. Infinite retry loops without backoff — add bounded retry with exponential backoff
+
+**Linux reference**: `drivers/ata/libata-eh.c` — `ata_eh_link_autopsy()` for error classification pattern. Linux distinguishes transient errors (retry), permanent errors (fail), and protocol errors (reset).
+
+**File paths**:
+- `recipes/core/base/source/drivers/storage/ahcid/src/main.rs`
+- `recipes/core/base/source/drivers/net/e1000d/src/device.rs`
+- `recipes/core/base/source/drivers/net/rtl8168d/src/device.rs`
+- `recipes/core/base/source/drivers/audio/ihdad/src/main.rs`
+- `recipes/core/base/source/drivers/audio/ac97d/src/device.rs`
+- `local/recipes/drivers/ehcid/source/src/`, `ohcid/`, `uhcid/`
+
+**Acceptance**: `grep -r 'unwrap()' recipes/core/base/source/drivers/` returns zero matches for hardware I/O paths. Each `unwrap()` removal includes a `log::error!()` before the error return.
+
+### T0.2: Driver Logging Standardization
+
+**Problem**: Drivers use inconsistent logging — some use `println!`, some `eprintln!`, some `log::info!`, some no logging at all. Makes debugging hardware issues on bare metal nearly impossible.
+
+**Task**: Standardize all drivers to use the `log` crate with logd integration:
+1. Replace `println!`/`eprintln!` with `log::info!`/`log::warn!`/`log::error!`
+2. Log every hardware initialization step (PCI probe, BAR mapping, IRQ registration)
+3. Log every error with the hardware register values that caused it
+4. Add `log::debug!` for register read/write traces (behind a feature flag or compile-time config)
+
+**Linux reference**: `drivers/net/ethernet/intel/e1000e/netdev.c` — `e_err()` macro with per-driver message prefix. Linux uses `netdev_err()`, `netdev_warn()`, `netdev_info()` with device context.
+
+**Acceptance**: Every driver produces at minimum: one `info!` on start, one `info!` on successful init, one `error!` per failure path with register dump. Verified by booting in QEMU and checking serial output.
+
+### T0.3: Driver Lifecycle Documentation
+
+**Problem**: No documentation exists for driver initialization sequences, required resources, or expected behavior. New contributors cannot understand or debug drivers.
+
+**Task**: For each driver category (storage, network, audio), create a brief `DRIVERS.md` in the driver directory documenting:
+1. Hardware initialization sequence (PCI probe → BAR mapping → device reset → capability enumeration → ready)
+2. Required kernel schemes (scheme:memory, scheme:irq, scheme:pci)
+3. Known hardware quirks
+4. Linux source file(s) to cross-reference
+
+**Acceptance**: `DRIVERS.md` exists in `recipes/core/base/source/drivers/storage/`, `drivers/net/`, `drivers/audio/` with the above sections.
+
+---
+
+## Phase 1: Storage Drivers (Weeks 2-6)
+
+### T1.1: AHCI NCQ Support
+
+**Problem**: ahcid is 109 lines, only basic PIO/DMA read/write. No NCQ. SSD throughput is 3-5x slower than possible.
+
+**Linux reference**: `drivers/ata/libata-sata.c:35` — `sata_fsl_host_intr()` with NCQ error handling. `drivers/ata/ahci.c:1423` — `ahci_qc_prep()` for FIS/command table setup.
+
+**Implementation**:
+1. Add command queue structure to `ahcid/src/ahci/` — track up to 32 pending commands per port
+2. Implement `ahci_qc_issue()` modeled on Linux `ata_qc_issue()`:
+   - Allocate command slot from device command table
+   - Fill command FIS (Frame Information Structure) with READ/WRITE FPDMA command
+   - Set PRDT (Physical Region Descriptor Table) for DMA scatter-gather
+   - Issue command via PxCI (Port Command Issue) register write
+3. Implement `ahci_port_intr()` modeled on Linux `ahci_port_intr()`:
+   - Read PxIS (Port Interrupt Status)
+   - Handle D2H Register FIS (command completion)
+   - Handle SDB FIS (NCQ completion with per-tag status)
+   - Handle PIO Setup FIS (for ATAPI)
+   - Handle Device-to-Host FIS errors
+4. Add per-tag completion tracking using `PxSACT` (SActive) register
+
+**Files to modify/create**:
+- `recipes/core/base/source/drivers/storage/ahcid/src/main.rs` — NCQ enable in `ahci_init()`
+- `recipes/core/base/source/drivers/storage/ahcid/src/ahci/` — new `ncq.rs`, `fis.rs`
+
+**Acceptance**:
+- `fio` random read test on SSD shows ≥3x improvement over current PIO-only
+- NCQ depth 32 verified via `PxSACT` register dump in debug output
+- QEMU with `-device ahci,id=ahci` and `-drive file=...,if=none,id=drive0` produces NCQ completions
+
+### T1.2: AHCI Power Management
+
+**Problem**: No power management. Laptops drain battery with disk constantly powered.
+
+**Linux reference**: `drivers/ata/libata-eh.c:3682` — `ata_eh_handle_port_suspend()`. `drivers/ata/ahci.c` — `ahci_set_lpm()` for Partial/Slumber link power management.
+
+**Implementation**:
+1. Add link power management to `ahci_init()`:
+   - Set PxCMD.ICC (Interface Communication Control) to Slumber after idle
+   - Set PxSCTL.DET to disable PHY when port is idle
+   - Restore on new command arrival
+2. Add ALPM (Aggressive Link Power Management):
+   - Set AHCI_HOST_CAP2.SDS (Supports Device Sleep) if available
+   - Enable HIPM (Host Initiated Power Management) and DIPM (Device Initiated)
+3. Add device sleep (DevSlp) for SATA 3.2+ devices
+
+**Acceptance**: After 5 seconds of idle, PxSSTS.DET reports 0x4 (PHY offline). New command wakes the link within 100ms. Verified on bare metal with SATA SSD.
+
+### T1.3: AHCI TRIM/Discard
+
+**Problem**: SSDs degrade over time without TRIM. Write amplification increases.
+
+**Linux reference**: `drivers/ata/libata-scsi.c` — `ata_scsi_unmap_xlat()` maps SCSI UNMAP to ATA DATA SET MANAGEMENT with TRIM bit.
+
+**Implementation**:
+1. Add TRIM command support using ATA DATA SET MANAGEMENT (opcode 0x06) with TRIM bit
+2. Implement range list construction (LBA + sector count per entry, up to 64 entries)
+3. Wire into filesystem TRIM/discard path via scheme discard operation
+
+**Acceptance**: `fstrim /` (or redoxfs equivalent) issues DATA SET MANAGEMENT commands visible in AHCI debug output. SSD wear leveling counters show improvement after TRIM.
+
+### T1.4: NVMe Multiple Queue Support
+
+**Problem**: NVMe driver uses single I/O queue. NVMe supports up to 64K queues for parallelism.
+
+**Linux reference**: `drivers/nvme/host/pci.c` — `nvme_reset_work()` for controller initialization with queue count negotiation.
+
+**Implementation**:
+1. Implement `nvme_create_io_queues()` modeled on Linux:
+   - Read controller capabilities for maximum queue count
+   - Create one admin submission + completion queue pair
+   - Create N I/O submission + completion queue pairs
+   - Configure interrupt vectors for MSI-X per-queue
+2. Implement round-robin queue selection for I/O submission
+
+**Acceptance**: NVMe device in QEMU reports ≥4 I/O queues. `fio` shows throughput scaling with queue count.
+
+---
+
+## Phase 2: Network Drivers (Weeks 4-8)
+
+### T2.1: e1000 Interrupt Moderation + Checksum Offload
+
+**Problem**: e1000d is 458 lines with no hardware offloads. Every packet triggers an interrupt. Throughput is limited by interrupt rate (~10K pps max).
+
+**Linux reference**: `drivers/net/ethernet/intel/e1000e/netdev.c:4200` — `e1000_configure_itr()`. `e1000e/netdev.c` — `e1000_tx_csum()`, `e1000_rx_checksum()`.
+
+**Implementation**:
+1. **Interrupt moderation** (ITR):
+   - Program E1000_ITR register with dynamic moderation
+   - Implement `e1000_update_itr()` modeled on Linux: increase ITR under high load, decrease under low load
+   - Target: reduce interrupts from 10K/s to 1K/s under full load
+2. **TX checksum offload**:
+   - Set E1000_TXD_CMD_IPCSS/TUCMD_IPCSS for IP header checksum
+   - Set E1000_TXD_CMD_TCP/UDP for TCP/UDP pseudo-header checksum
+   - Set context descriptor for checksum parameters
+3. **RX checksum offload**:
+   - Parse E1000_RXD_STAT_IPCS/TCPCS status bits
+   - Pass checksum status to netstack
+
+**Files to modify**:
+- `recipes/core/base/source/drivers/net/e1000d/src/device.rs` — add ITR, checksum methods
+- `recipes/core/base/source/drivers/net/e1000d/src/main.rs` — wire into TX/RX paths
+
+**Acceptance**: `iperf3` TCP throughput ≥5x improvement. Interrupt rate drops from ~10K/s to ≤2K/s under load. Wireshark capture shows valid checksums on TX packets.
+
+### T2.2: e1000 TSO/GSO
+
+**Problem**: TCP segmentation is done in software. Large sends require per-packet overhead.
+
+**Linux reference**: `drivers/net/ethernet/intel/e1000e/netdev.c:5305` — `e1000_tso()`.
+
+**Implementation**:
+1. Implement `e1000_tso()` modeled on Linux:
+   - Parse GSO descriptor from netstack
+   - Set E1000_TXD_CMD_TSE (TCP Segmentation Enable)
+   - Set MSS (Maximum Segment Size) in context descriptor
+   - Set header length in context descriptor
+   - Hardware will segment one large buffer into MSS-sized packets
+2. Implement `e1000_tx_csum()` for combined TSO + checksum offload
+
+**Acceptance**: TCP send of 64KB buffer produces hardware-segmented packets (verified via virtio-net capture on host side). Throughput for large sends ≥2x improvement.
+
+### T2.3: r8169 PHY Configuration
+
+**Problem**: rtl8168d has no per-chip PHY initialization. Works on QEMU's default r8169 but fails on many real chips.
+
+**Linux reference**: `drivers/net/ethernet/realtek/r8169_phy_config.c` (1,354 lines of per-chip init sequences).
+
+**Implementation**:
+1. Identify chip version from MAC0-MAC4 registers (Linux: `rtl8169_get_mac_version()`)
+2. Add PHY init sequences for common chip versions:
+   - RTL_GIGA_MAC_VER_34 (RTL8168EP/8111EP)
+   - RTL_GIGA_MAC_VER_44 (RTL8168FP/8111FP)
+   - RTL_GIGA_MAC_VER_51 (RTL8168H/8111H)
+3. Implement MDIO register read/write for PHY access
+4. Add PHY status polling for link detection
+
+**Files to modify**:
+- `recipes/core/base/source/drivers/net/rtl8168d/src/device.rs` — chip detection, PHY init
+- `recipes/core/base/source/drivers/net/rtl8168d/src/main.rs` — init sequence
+
+**Acceptance**: RTL8168 NIC in real hardware enumerates, links up, and passes `ping`. Multiple chip versions tested.
+
+### T2.4: Jumbo Frame Support (e1000 + r8169)
+
+**Problem**: MTU limited to 1500. Jumbo frames (9000 bytes) reduce per-packet overhead for bulk transfers.
+
+**Linux reference**: `e1000e/netdev.c` — `e1000_change_mtu()`. `r8169_main.c:4352` — `rtl_jumbo_config()`.
+
+**Implementation**:
+1. Configure RX buffer size for jumbo frames (up to 9KB)
+2. Set MAX_FRAME_SIZE register
+3. Update TX descriptor buffer size
+4. Expose MTU configuration through scheme interface
+
+**Acceptance**: `ifconfig eth0 mtu 9000` succeeds. `iperf3` with 9KB MTU shows reduced CPU usage per Gbps.
+
+---
+
+## Phase 3: Audio Drivers (Weeks 6-10)
+
+### T3.1: HDA Codec Auto-Detection
+
+**Problem**: ihdad (143 lines) has no codec detection. Audio works on zero real machines.
+
+**Linux reference**: `sound/hda/hda_codec.c` — `snd_hda_codec_new()` for codec discovery. `sound/hda/hda_generic.c` for generic codec parser.
+
+**Implementation**:
+1. Implement HDA controller initialization:
+   - Read GCAP (Global Capabilities) register for stream/IRQ info
+   - Reset controller via GCTL.CRST
+   - Set CORB/RIRB (Command/Response Ring Buffers) for codec communication
+2. Implement codec discovery:
+   - Read STATETS register for codec presence bitmap
+   - For each present codec, send GET_PARAMETER verb to read:
+     - Vendor/Device ID (F00)
+     - Subsystem ID (F20)
+     - Revision ID (F02)
+     - Node count (F04)
+     - Function group type (F05)
+3. Implement codec parsing:
+   - Walk widget tree starting from AFG (Audio Function Group) node
+   - Parse each widget's parameters (amp capabilities, connection list, pin config)
+   - Build internal topology representation
+4. Add codec table for common codecs:
+   - Realtek ALC887/ALC888/ALC892 (most common desktop)
+   - Realtek ALC269/ALC282/ALC283 (most common laptop)
+   - Conexant CX20561/CX20585
+   - IDT 92HD73C1/92HD81B1C5
+
+**Files to modify/create**:
+- `recipes/core/base/source/drivers/audio/ihdad/src/main.rs` — controller init
+- `recipes/core/base/source/drivers/audio/ihdad/src/hda/` — new `codec.rs`, `widget.rs`, `codecs/`
+- `recipes/core/base/source/drivers/audio/ihdad/src/hda/registers.rs` — register definitions
+
+**Acceptance**: Real hardware with Intel HDA controller enumerates codecs. `lspci` shows HD Audio device with driver attached. Codec dump shows vendor/device IDs matching known codecs.
+
+### T3.2: HDA Mixer Controls + Jack Detection
+
+**Problem**: No volume control, no muting, no jack detection. Audio output is fixed-volume or silent.
+
+**Linux reference**: `sound/hda/hda_generic.c` — `create_mute_volume_ctl()`. `sound/hda/hda_jack.c` — `snd_hda_jack_detect()`.
+
+**Implementation**:
+1. Add mixer controls for each output path:
+   - Volume control (AMP-OUT mute + gain on pin widget)
+   - Capture control (AMP-IN mute + gain on ADC widget)
+   - Master volume (combined output volume)
+2. Implement jack detection:
+   - Enable unsolicited response for jack-sense pin widgets
+   - Handle unsolicited response in CORB/RIRB interrupt
+   - Report jack state (plugged/unplugged) via scheme
+3. Wire mixer controls to audiod for system-wide volume management
+
+**Files to modify**:
+- `recipes/core/base/source/drivers/audio/ihdad/src/hda/codec.rs` — mixer controls
+- `recipes/core/base/source/drivers/audio/ihdad/src/hda/jack.rs` — jack detection (new)
+- `recipes/core/base/source/drivers/audio/audiod/src/scheme.rs` — volume interface
+
+**Acceptance**: Volume control changes audible output level. Plugging/unplugging headphones triggers jack event (visible in debug output). Headphone and speaker paths are independent.
+
+### T3.3: HDA Stream Setup and PCM Playback
+
+**Problem**: No actual PCM audio output. HDA hardware configured but no audio data flows.
+
+**Linux reference**: `sound/hda/hda_controller.c` — `azx_pcm_open()` / `azx_pcm_prepare()` / `azx_pcm_trigger()`.
+
+**Implementation**:
+1. Implement stream (PCM) management:
+   - Allocate stream descriptor from controller (SD0-SDn)
+   - Configure stream format (sample rate, bits, channels)
+   - Set BDL (Buffer Descriptor List) for DMA
+   - Set stream position in buffer (LPIB register)
+2. Implement PCM playback path:
+   - `pcm_open(format)` — allocate stream, configure format
+   - `pcm_write(data)` — write audio samples to DMA buffer
+   - `pcm_start()` — set RUN bit in stream control
+   - `pcm_stop()` — clear RUN bit
+3. Implement CORB/RIRB interrupt handling for unsolicited responses
+4. Implement stream interrupt handling for buffer completion (BCIS)
+
+**Files to modify**:
+- `recipes/core/base/source/drivers/audio/ihdad/src/hda/stream.rs` — stream management (new)
+- `recipes/core/base/source/drivers/audio/ihdad/src/hda/dma.rs` — BDL setup (new)
+- `recipes/core/base/source/drivers/audio/audiod/src/` — PCM routing
+
+**Acceptance**: `aplay` (or redox equivalent) plays a WAV file and produces audible output. `parec` captures from microphone. Loopback (output → input) works without distortion.
+
+### T3.4: AC97 Multiple Codec + Mixer Support
+
+**Problem**: ac97d supports only single codec at fixed configuration. No volume/mute.
+
+**Linux reference**: `sound/pci/ac97/ac97_codec.c` (3,134 lines) — multi-codec architecture.
+
+**Implementation**:
+1. Add codec slot detection (AC97 supports up to 4 codecs on one controller)
+2. Add mixer register read/write for volume/mute
+3. Add record source selection
+
+**Acceptance**: Desktop with AC97 audio codec produces audible output with adjustable volume.
+
+---
+
+## Phase 4: Input Completeness (Weeks 3-5)
+
+### T4.1: PS/2 i8042 Controller Reset
+
+**Problem**: ps2d assumes controller is ready. Real hardware may need reset sequence.
+
+**Linux reference**: `drivers/input/serio/i8042.c:522` — `i8042_controller_check()`.
+
+**Implementation**:
+1. Add controller self-test: Write 0xAA to command register, expect 0x55 response
+2. Add controller initialization: disable devices, flush buffer, enable
+3. Add AUX (mouse) port detection
+4. Add timeout handling for missing ACK from controller
+
+**Files to modify**:
+- `recipes/core/base/source/drivers/input/ps2d/src/controller.rs`
+
+**Acceptance**: PS/2 keyboard and mouse work on real hardware after cold boot. No "LED command ACK timeout" warnings.
+
+### T4.2: Touchpad Protocol Detection
+
+**Problem**: USB HID touchpads work as basic mice. No multi-touch, no gestures.
+
+**Linux reference**: `drivers/input/mouse/synaptics.c` for Synaptics protocol. `drivers/input/mouse/alps.c` for ALPS.
+
+**Implementation**:
+1. Add PS/2 touchpad protocol detection for Synaptics/ALPS/Elantech
+2. Parse multi-touch data from HID digitizer reports
+3. Expose gesture events through evdevd scheme
+
+**Acceptance**: Laptop touchpad supports two-finger scroll. Multi-touch coordinates reported correctly.
+
+---
+
+## Phase 5: Validation & Documentation (Weeks 1-12, parallel)
+
+### T5.1: Per-Driver Test Harnesses
+
+**Task**: Create QEMU-based test scripts for each driver category:

+- `local/scripts/test-audio-qemu.sh` — boots with HDA + AC97, plays test tone
+
+**Acceptance**: Each script exits 0 on success, produces captured serial output with test results.
+

+
+## Addendum A: Kernel Substrate Audit (2026-05-04 deep re-assessment)
+
+### A.1 CPU / SMP / Timer Initialization
+
+**Red Bear**: Kernel arch/x86_64 (502 lines) + arch/x86_shared + time.rs
+**Linux**: `arch/x86/kernel/smpboot.c` (1,511) + `arch/x86/kernel/apic/apic.c` (2,694) + `arch/x86/kernel/tsc.c` (1,612) + `kernel/time/tick-common.c` (595) = 6,412 lines (subset)
+
+**What Red Bear has**:
+- Basic x86_64 boot (GDT, IDT, page tables)
+- x2APIC/SMP detected from MADT
+- HPET timer
+
+**What Linux has that Red Bear is missing**:
+- ❌ BSP/AP handoff protocol — Linux: `smpboot.c:895` `do_boot_cpu()`
+- ❌ CPU hotplug (online/offline) — Linux: `smpboot.c:1312` `cpu_up()` / `cpu_down()`
+- ❌ TSC calibration and synchronization — Linux: `tsc.c:1186` `check_tsc_sync_source()`
+- ❌ APIC timer calibration and per-CPU timers — Linux: `apic.c:294` `calibrate_APIC_clock()`
+- ❌ Interrupt affinity and vector allocation — Linux: `kernel/irq/manage.c` (2,803 lines)
+- ❌ IPI (Inter-Processor Interrupt) routing — Linux: `apic/ipi.c`
+- ❌ CPU idle states (C-states) — Linux: `arch/x86/kernel/acpi/cstate.c`
+- ❌ Clock source rating and switching — Linux: `kernel/time/clocksource.c`
+
+**Priority**: SMP bring-up stability and TSC sync are critical for multi-core correctness. Without APIC timer calibration, scheduler tick is unreliable.
+
+### A.2 DMA / Memory / IOMMU Substrate
+
+**Red Bear**: kernel memory/mod.rs (1,266 lines) + iommu daemon (4,411 lines)
+**Linux**: `kernel/dma/mapping.c` (1,016) + `drivers/iommu/` (~30K) + `mm/` subsystem
+
+**What Red Bear has**:
+- Physical memory mapping via scheme:memory
+- Basic IOMMU daemon (4,411 lines — substantial, AMD-Vi + Intel VT-d)
+- Page table management in iommu daemon
+
+**What Linux has that Red Bear is missing**:
+- ❌ Coherent DMA API — Linux: `kernel/dma/mapping.c` `dma_alloc_coherent()`
+- ❌ Streaming DMA API — Linux: `kernel/dma/mapping.c` `dma_map_single()`
+- ❌ Scatter-gather DMA — Linux: `lib/scatterlist.c`
+- ❌ DMA pool/zone management
+- ❌ SWIOTLB bounce buffering — Linux: `kernel/dma/swiotlb.c`
+- ❌ IOMMU DMA remapping per-device — the iommu daemon exists but Linux handles this in-kernel with `iommu_dma_ops`
+- ❌ DMA debug and error injection — Linux: `kernel/dma/debug.c`
+
+**Priority**: DMA API is prerequisite for any driver doing scatter-gather. Without coherent DMA, drivers must manually manage cache coherency.
+
+### A.3 Virtio Completeness
+
+**Red Bear**: virtio-core (1,545 lines) + virtio-blkd + virtio-netd + virtio-gpud
+**Linux**: `drivers/virtio/virtio.c` (730) + `virtio_ring.c` (3,940) + `virtio_pci_modern.c` (1,301) + blk/net/gpu drivers (14,957 total)
+
+**What Red Bear has**:
+- Basic virtio PCI transport (legacy)
+- Split virtqueue with basic ring management
+- virtio-blk, virtio-net, virtio-gpu drivers
+
+**What Linux has that Red Bear is missing**:
+- ❌ **Virtio 1.0 modern PCI transport** — Linux: `virtio_pci_modern.c` (1,301 lines). Red Bear only uses legacy.
+- ❌ **Packed virtqueue** (Virtio 1.1) — Linux: `virtio_ring.c` supports both split and packed
+- ❌ **Multiqueue support** — Linux: virtio-net supports up to 16 TX/RX queue pairs via MSI-X
+- ❌ **Virtio feature negotiation** — Red Bear hardcodes features; Linux does dynamic negotiation
+- ❌ **Device reset protocol** — Linux: `virtio.c:237` `virtio_reset_device()`
+- ❌ **Virtio-MMIO transport** (for ARM/RISC-V VMs)
+- ❌ **Virtio-balloon** (memory ballooning)
+
+**Priority**: Modern PCI transport is required for QEMU machine types `q35` and newer. Packed virtqueues improve throughput. Multiqueue is critical for network performance.
+
+### A.4 CPU Frequency / Thermal / Power
+
+**Red Bear**: cpufreqd (176 lines — real implementation with governors), thermald (837 lines), hwrngd (534 lines), redbear-upower, redbear-acmd, redbear-ecmd
+**Linux**: `drivers/cpufreq/cpufreq.c` (3,081) + `drivers/thermal/thermal_core.c` (1,956) + `drivers/char/hw_random/core.c` (739)
+
+**cpufreqd status**: 176 lines with ondemand/performance/powersave governors, MSR-based P-state control via IA32_PERF_CTL, and CPU load measurement via `/scheme/sys`. Still missing vs Linux:
+- ❌ Governor framework (performance, powersave, ondemand, schedutil)
+- ❌ ACPI P-state (_PSS) integration
+- ❌ Intel P-state / HWP driver
+- ❌ AMD CPPC driver
+
+**thermald status**: 837 lines — basic thermal monitoring exists but missing:
+- ❌ Thermal zone trip points (passive/active/critical)
+- ❌ Cooling device registration
+- ❌ Fan speed control via ACPI
+
+**hwrngd status**: 534 lines — reasonable random number daemon. Missing:
+- ❌ Entropy estimation per FIPS 140-2
+- ❌ Multiple entropy source mixing (CPU jitter, TPM, RDRAND)
+- ❌ `/dev/hwrng` interface
+
+**Priority**: cpufreqd has basic governor support but still needs ACPI P-state integration, Intel HWP, and AMD CPPC for full functionality.
+
+### A.5 Block Layer / Filesystem Integration
+
+**Red Bear**: No dedicated block layer — each storage driver handles I/O directly via DiskScheme
+**Linux**: `block/blk-mq.c` (5,309) + `block/blk-flush.c` (540) + `block/genhd.c` + `block/elevator.c`
+
+**What Linux has that Red Bear is missing**:
+- ❌ Multi-queue block I/O — Linux: `blk-mq.c` — per-CPU queues + tag sets
+- ❌ I/O scheduling (mq-deadline, kyber, bfq) — Linux: `block/mq-deadline.c`
+- ❌ Flush/FUA semantics — Linux: `block/blk-flush.c`
+- ❌ I/O merging and sorting
+- ❌ Request timeout and retry — Linux: `block/blk-mq.c` `blk_mq_check_expired()`
+- ❌ Block device partitioning (MBR/GPT handled by partitionlib library)
+- ❌ Queue depth management and back-pressure
+
+**Red Bear storage drivers** (nvmed 1,318 lines; usbscsid 1,622 lines; ided 773 lines) all implement their own I/O dispatch. The lack of a shared block layer means each driver reinvents queuing, timeout, and retry logic.
+
+**Priority**: Block layer is prerequisite for NCQ, NVMe multi-queue, TRIM propagation, and crash consistency.

+
+---
+
+### 2.3 Storage — AHCI (No existing plan — CRITICAL GAP)
+
+**Red Bear**: ahcid (109 lines — main.rs only)
+**Linux**: `drivers/ata/ahci.c` (2,173 lines) + `libahci.c` (2,447 lines) + `libata-core.c` (5,296 lines)
+
+**Red Bear current state**: Minimal — only basic SATA IDENTIFY and PIO/DMA read/write.
+
+**What Linux has that Red Bear is missing** (cross-referenced from `drivers/ata/ahci.c` and `libata-core.c`):
+- ❌ **NCQ** (Native Command Queuing) — 32-command depth, critical for SSD performance
+  - Linux: `libata-sata.c` — `ata_scsi_queuecmd()`, `ata_qc_issue()`
+  - Red Bear reference: `drivers/ata/libata-sata.c:35` — `sata_fsl_host_intr()` with NCQ error handling
+- ❌ **FIS-based switching** (port multiplier support)
+  - Linux: `drivers/ata/ahci.c:1423` — `ahci_qc_prep()` handles FIS registers

+- ❌ **Error recovery** — Linux has extensive EH (Error Handler) in `libata-eh.c` (3,915 lines)
+
+**Priority**: NCQ alone can improve SSD throughput 3-5x. TRIM prevents SSD degradation. Power management critical for laptops.
+
+---
+

+
+---
+
+### 2.5 Network — e1000 / r8168 (No existing plan — CRITICAL GAP)
+
+**Red Bear**: e1000d (458 lines) + rtl8168d (460 lines) = 918 lines total
+**Linux**: e1000e (30,203 lines) + r8169 (7,690 lines) = 37,893 lines total
+
+**What Linux has that Red Bear is missing** (cross-referenced from `drivers/net/ethernet/intel/e1000e/` and `drivers/net/ethernet/realtek/r8169_main.c`):

+### 2.6 Audio — HDA / AC97 (No existing plan — GAP)
+
+**Red Bear**: ihdad (143 lines) + ac97d (467 lines) = 610 lines total
+**Linux**: `sound/hda/` + `sound/pci/ac97/` (~10K lines)
+
+**What Linux has that Red Bear is missing**:
+- ❌ **HDA codec auto-detection** (Realtek, Conexant, IDT, VIA, etc.)
+  - Linux: `sound/hda/hda_codec.c` — `snd_hda_codec_new()`
+- ❌ **HDA codec-specific initialization** (pin configs, EAPD, GPIO)
+  - Linux: `sound/hda/hda_generic.c` — generic parser
+- ❌ **HDA power management** (codec power states, D0/D3)
+  - Linux: `sound/hda/hda_codec.c` — `snd_hda_codec_set_power_state()`
+- ❌ **Mixer controls** (volume, mute, capture, jack sensing)
+  - Linux: `sound/hda/hda_generic.c` — `create_mute_volume_ctl()`
+- ❌ **Jack detection** (headphone/mic plug/unplug)
+  - Linux: `sound/hda/hda_jack.c` — `snd_hda_jack_detect()`
+- ❌ **HDMI/DP audio** (digital audio over display)
+  - Linux: `sound/hda/hda_eld.c` — ELD (EDID-Like Data) parsing
+- ❌ **AC97 multiple codec support**
+  - Linux: `sound/pci/ac97/ac97_codec.c` (3,134 lines)
+- ❌ **Sample rate conversion / format negotiation**
+
+**Priority**: Codec auto-detection is the minimum needed for real hardware audio to work beyond basic beeps. Without it, audio works on zero real machines.

+
+### 2.7 USB — xHCI (Covered: USB-IMPLEMENTATION-PLAN.md)
+
+**Red Bear**: xhcid (~1,100 lines)
+**Linux**: `drivers/usb/host/xhci.c` (5,705) + `xhci-ring.c` (4,488) + `xhci-hub.c` (1,995) = 12,188 lines
+
+**What Red Bear has**:
+- ✅ Basic control/bulk/interrupt/isochronous transfers
+- ✅ Device enumeration (basic)
+
+**What Linux has that Red Bear is missing** (cross-referenced):
+- ❌ **Transfer ring management** (TRB dequeue, cycle bit tracking)
+  - Linux: `xhci-ring.c:253` — `inc_deq()` with cycle state handling
+- ❌ **Stream support** (bulk streams for UAS)
+  - Linux: `xhci-ring.c:3500` — `xhci_queue_stream_transfer()`
+- ❌ **USB 3.x SuperSpeed features** (U1/U2/U3 link states)
+  - Linux: `xhci.c:4560` — `xhci_set_link_state()`
+- ❌ **Isochronous scheduling** (proper bandwidth calculation)
+  - Linux: `xhci-ring.c:3718` — `xhci_queue_isoc_tx()`
+- ❌ **Command ring handling** (TRB abort, stop endpoint)
+  - Linux: `xhci-ring.c:173` — `xhci_abort_cmd_ring()`
+- ❌ **Error recovery** (transfer event TRB error handling)
+  - Linux: `xhci-ring.c:2636` — `handle_tx_event()` with extensive error cases
+- ❌ **Controller reset/recovery** (xHCI controller hang detection)
+  - Linux: `xhci.c:5173` — `xhci_handle_command_timeout()`
+
+**Priority**: Referenced by USB-IMPLEMENTATION-PLAN.md.

+### 2.8 GPU / DRM (Covered: DRM-MODERNIZATION-EXECUTION-PLAN.md)
+
+Redox-drm (8,427 lines) vs Linux AMD+i915 (1,284,210 lines). Referenced by existing plan. Key gaps already documented.
+

+
+### 2.9 Input — PS/2 + USB HID
+
+**Red Bear**: ps2d + usbhidd (~500 lines)
+**Linux**: `drivers/input/serio/i8042.c` (1,254 lines) + `drivers/hid/usbhid/` + `drivers/input/evdev.c`
+
+**What Linux has that Red Bear is missing**:
+- ❌ **i8042 controller detection and reset** — Linux: `i8042.c:522` — `i8042_controller_check()`
+- ❌ **PS/2 hotplug** — Linux: `i8042.c` — `i8042_interrupt()` with AUX detection
+- ❌ **LED feedback** — Red Bear has basic LED support (P3 patch)
+- ❌ **Touchpad protocol detection** (Synaptics, ALPS, Elantech)
+- ❌ **Multitouch support** (USB HID digitizer class)
+- ❌ **Force feedback** (game controllers) — Linux: `drivers/hid/hid-pidff.c`

+     * automatically initiated.
+     *
+     * Some examples:
+     *
+     * - When the user types text in a search field, wait no longer than this duration after
+     *   the user completes typing before starting the search
+     * - When loading data which would commonly arrive rapidly enough to not require interaction,
+     *   wait this long before showing a spinner
+     *
+     * This might seem an arbitrary number, but given the psychological effect that three
+     * seconds seems to be what humans consider a moment (and in the case of waiting for
+     * something to happen, a moment is that time when you think "this is taking a bit long,
+     * isn't it?"), the idea is to postpone for just before such a conceptual moment. The reason
+     * for the two seconds, rather than three, is to function as a middle ground: Not long enough
+     * that the user would think that something has taken too long, for also not so fast as to
+     * happen too soon.
+     *
+     * See also
+     * https://www.psychologytoday.com/blog/all-about-addiction/201101/tick-tock-tick-hugs-and-life-in-3-second-intervals
+     * (the actual paper is hidden behind an academic paywall and consequently not readily
+     * available to us, so the source will have to be the blog entry above)
+     *
+     * \note This should __not__ be used as an animation duration, as it is deliberately not scaled according
+     * to the animation settings. This is specifically for determining when something has taken too long and
+     * the user should expect some kind of feedback. See veryShortDuration, shortDuration, longDuration, and
+     * veryLongDuration for animation duration choices.
