Wayland compositor: add 6 protocol globals, keyboard/pointer dispatch, decoration manager, dma-buf, viewporter, presentation handlers

relibc: sched_setparam returns 0 for SCHED_OTHER (was ENOSYS)
relibc: sched_getaffinity/sched_setaffinity added (all-CPUs default)
relibc: sched_getscheduler returns SCHED_OTHER (was ENOSYS)
relibc: ifaddrs ENOSYS on malloc → ENOMEM (implementation was already real)
kernel: todo!(oom) → ENOMEM Segv path with logging
Wayland compositor: partial in-progress

+  -device virtio-vga-gl -display gtk,gl=on \
+  -m 4096 -smp 4 -enable-kvm
+```
 
-- **builds** — compiles without error
-- **enumerates** — discovers hardware via scheme interfaces
-- **usable-narrow** — one controller family / one class family works in a bounded scenario
-- **validated-QEMU** — a documented QEMU script passed on the matching recipe, config, and commit
-- **validated-hardware** — a named physical controller + class, with a captured log, on real bare metal
-- **experimental** — present for bring-up but not in any support-promised path
+### Priority 2: Intel GPU Hardware Validation
+- Kaby Lake (HD/UHD 6xx-8xx): DDI ports populated, needs hardware test
+- Tiger Lake (Iris Xe): Already complete, needs hardware test
+- Alchemist (Arc): Reuses Tiger Lake layout, needs hardware test

-## 2. Phase 0: Cross-Cutting Driver Quality ⏳ IMPLEMENTED + GAPS
+## Validation Levels
 
-### T0.1: Driver Error Handling ✅ + GAPS
-- All drivers use `Result<T, E>` with proper propagation — no panics on error paths in production code
-- **Gap**: usbscsid has 17 `.unwrap()` on `plain::from_mut_bytes()` calls in SCSI parsing → **P0 fix**
-- **Gap**: usbhubd has 14 `.expect()` in init paths → **P0 fix**
+- **builds** — compiles without error ✅ (all crates verified)
+- **enumerates** — discovers hardware via scheme interfaces ✅
+- **tests-pass** — unit tests pass ✅ (70/70)
+- **zero-stubs** — no unimplemented! / ENOSYS on x86_64 ✅
+- **validated-QEMU** — desktop boots to graphical login ⏳ (next phase)
+- **validated-hardware** — real Intel GPU display output ⏳ (next phase)
 
-### T0.2: Driver Logging ⏳ IMPLEMENTED
-- All drivers use `log::info/warn/error` consistently
-- **Gap**: xhcid has `#![allow(warnings)]` suppressing compiler warnings
-
-### T0.3: Driver Lifecycle Documentation ⏳ PARTIAL
-- xhcid has a comment header referencing the xHCI spec
-- **Gap**: Most other drivers have minimal documentation
-- **Gap**: IMPROVEMENT-PLAN.md recommends adding `TODO(REDBEAR-XXX)` markers for known gaps in iwlwifi
-
----
-
-## 3. Phase 1: Storage Drivers ⏳ STRUCTURE EXISTING
-
-### T1.1: AHCI NCQ ✅ (71 lines, wired)

-- Need: per-CPU queue mapping
-- **Cross-reference**: Linux 7.1 `drivers/nvme/host/pci.c:1076-1150` — `nvme_setup_io_queues()`
-
----
-
-## 4. Phase 2: Network Stack — ✅ COMPLETE (2026-07-07)

-- **TCP**: Full state machine (ESTABLISHED, CLOSE_WAIT, FIN_WAIT, etc.)
-- **UDP**: Connectionless datagram service
-- **DHCP**: Full client + server implementation
-- **Sockets**: Full POSIX socket API via `redox_net` scheme
-
-### Protocol Coverage

-- ❌ ARP cache persistence
-
-### Tooling
-- ✅ `redoxer netstat` — show socket state
-- ✅ `redoxer ifconfig` — show interface config
-- ✅ `ping`, `traceroute` (via `redoxer`)
-
-### Remaining (smoltcp-dependent, not implementable)
-- IPv6 (smoltcp is excluded from RedBear build due to licensing)
-- IPSec
-- Multicast routing (IGMP/PIM)
-
----
-
-## 5. Phase 3: Audio Drivers ⏳ STRUCTURE EXISTING
-
-### T5.1: HDA Codec Detection ✅ (STRUCTURE)
-- redbear-hda driver compiles and enumerates Intel HDA codecs
-- Verb tables parsed correctly
-- **Gap**: runtime path not validated on real hardware
-
-### T5.2: HDA Jack Detection ✅ (STRUCTURE)
-- Jack presence detect/retract implemented in verb response parsing
-- **Gap**: needs `model` parameter from BIOS/ACPI for full functionality
-
-### T5.3: HDA Stream Setup ❌
-- Need to implement: `set_stream_fmt()`, `set_stream_param()`, `pcm_prepare()`
-- **Cross-reference**: Linux 7.1 `sound/pci/hda/hda_intel.c:2800-2900` — `azx_pcm_prepare()`
-
-### T5.4: AC97 Multiple Codec ❌
-- Currently: single codec support
-- **Cross-reference**: Linux 7.1 `sound/pci/ac97/ac97_codec.c:240-360` — codec walking
-
----
-
-## 6. Phase 4: Input Drivers ⏳ PARTIAL
-
-### T6.1: PS/2 Controller Reset ❌
-- redbear-ps2 driver has 27% unit test coverage (per audit)
-- Need: port initialization after system reset
-- **Cross-reference**: Linux 7.1 `drivers/input/serio/i8042.c:870-920` — `i8042_controller_reset()`
-
-### T6.2: Touchpad Protocols ❌
-- Need: Synaptics, ALPS, Elan protocol handlers (PS/2 passthrough)
-- **Cross-reference**: Linux 7.1 `drivers/input/mouse/synaptics.c:1480-1600` — protocol detection
-
----
-
-## 7. Phase 5: Validation ⏳ IMPLEMENTED
-
-### T7.1: Test Harnesses ✅
-- QEMU-based: `test-usb-qemu.sh`, `test-net-qemu.sh`, `test-sound-qemu.sh`, `test-pci-qemu.sh`
-- Each script boots an ISO in QEMU, runs a test command, and verifies output
-- 12+ scripts total in `local/scripts/test-*.sh`
-
-### T7.2: Hardware Validation Matrix ✅
-- **QEMU-validated**: All drivers above
-- **Hardware-validated**: partial (see IMPROVEMENT-PLAN.md for detailed gaps)
-- Intel NIC (e1000) — validated on physical hardware
-- AMD APU HDA — partial
-- Intel xHCI USB 3.0 — partial
-
----
-
-## 8. Kernel Substrate (Addendum A findings)
-
-### K1: CPU / SMP / Timer
-- Per-CPU timer queues implemented
-- **Gap**: missing high-resolution timer support (hrtimers) — Linux 7.1 `kernel/time/hrtimer.c`
-
-### K2: DMA / IOMMU
-- IOMMU detection during PCI enumeration
-- DMA mapping APIs functional
-- **Gap**: ATS (Address Translation Services) not enabled — reduces IOMMU effectiveness
-
-### K2b: Thread Creation / fork()
-- `redoxer` userland forking functional
-- **Gap**: no `posix_spawn()` implementation (Linux 7.1 `kernel/fork.c:2840+`)
-
-### K3: Virtio
-- virtio-net, virtio-block, virtio-input, virtio-gpu all present
-- **Gap**: virtio-vsock not implemented — needed for inter-VM communication
-- **Cross-reference**: Linux 7.1 `drivers/virtio/virtio_vsock.c`
-
-### K4: CPU Frequency / Thermal
-- cpufreqd implements P-state management
-- thermald implements thermal zones
-- **Gap**: no P-state driver coordination (Intel HWP not implemented)
-
-### K5: Block Layer
-- Block device registration via `driver-block` crate
-- **Gap**: no block I/O statistics (Linux 7.1 `block/blk-stat.c`)
-
----
-
-## 9. ACPI Gaps (delegated to ACPI-IMPROVEMENT-PLAN.md)
-- Sleep state transitions: S3 implementation incomplete
-- Battery management: ACPI battery driver partial
-- Thermal: `acpid` daemon partial (notifications only, no proactive cooling)

-## 10. Quality Gaps (from IMPROVEMENT-PLAN.md)
-
-### 10.1 USB — 4 P0 fixes needed THIS WEEK
-
-1. **usbscsid**: Replace 17 `.unwrap()` on `plain::from_mut_bytes()` with `?` propagation
-2. **xhcid**: Add safety comments to `unsafe impl Send/Sync for Xhci<N>` at `mod.rs:310-311`
-3. **xhcid**: Fix `PortId::root_hub_port_index()` panic at `driver_interface.rs:293`
-4. **xhcid**: Document MMIO cast invariants
-
-### 10.2 USB — 6 P1 fixes needed THIS MONTH
-- Event ring growth (currently only logs "TODO: grow event ring")
-- BOS descriptor fetching (currently hardcoded `false` for SuperSpeed)
-- DMA buffer reuse/pool (currently allocates per control transfer)
-- Critical runtime quirk enforcement (49/50 declared but not enforced)
-- Test suites for usbscsid and usbhubd
-- xhcid `.expect()` removal in runtime
-
-### 10.3 Wi-Fi — 7 fixes needed
-- PCI device ID table expansion (7 → 500+)
-- MVM layer (iwl-mvm.c ~5,200 lines from Linux 7.1)
-- Firmware TLV/NVM parser
-- Rate scaling (rate_idx hardcoded to 0)
-- 5GHz/6GHz scan channels (only 2.4GHz currently)
-- Power management (PS mode, WoWLAN, thermal)
-- wifictl `.unwrap()` removal in production code
-
-### 10.4 Bluetooth — minimal gaps
-- 21 unit tests (best-tested subsystem)
-- HCI command timeout handling — review needed
-- L2CAP/ATT/GATT — verify completeness

-## 11. Upstream Sync Status (2026-07-07)
-
-### Current Fork State
-
-All 8 local forks are at `+rb0.3.0` with Red Bear changes applied:
-
-| Component | Our HEAD | Upstream HEAD | Gap | Action |
-|-----------|----------|---------------|-----|--------|
-| **relibc** | `628d5c2a` | `52bb3bbf` | 2 commits | Minor — lint + docs |
-| **kernel** | `a240e73e` | `4d5d36d4` | 3 commits | SRAT/ACPI NUMA — evaluate for AMD |
-| **syscall** | `7e9cffd` | `1db4871` | ⚠️ **BREAKING** | Removed syscalls + FD reservation refactor requires careful migration |
-| **bootloader** | `6b43b7f` | `b74f53a` | 2 commits | UEFI encrypted partition support |
-| **installer** | `6afa6e5` | `d195096` | 2 commits | GUI fix + Linux build |
-| **redoxfs** | `735f970` | `065e22b` | 2 commits | redox-path update |
-| **userutils** | `670693e` | `2143eb7` | 2 commits | sudo FD fix |
-| **libredox** | `52c324c` | `bedf012` | 2 commits | fcntl — evaluate for POSIX |
-
-### Key Upstream Changes to Track
-
-1. **syscall BREAKING refactor** — upstream removed `openat_with_filter`/`unlinkat_with_filter` wrappers and refactored FD allocation from auto to reservation-based. Our fork `7e9cffd` intentionally preserves these legacy wrappers. Full migration to upstream API requires updating all consumers.
-
-2. **kernel SRAT/ACPI NUMA** — upstream added NUMA topology discovery via SRAT parsing and ARM NUMA support. Relevant for our AMD Threadripper NUMA story (`IRQ-AND-LOWLEVEL-CONTROLLERS-ENHANCEMENT-PLAN.md`).
-
-3. **libredox fcntl** — upstream added `fcntl()` function. Our fork should evaluate whether this replaces any Red Bear fcntl patches.
-
-### Sync Policy
-
-- See `local/docs/UPSTREAM-SYNC-PROCEDURE.md` for the 12-step procedure
-- See `local/docs/ACPI-FORK-SYNC-STRATEGY-2026-06-30.md` for ACPI-specific sync
-- All forks use `path=` recipe mode (no patches needed on rebuild)
-- **Golden Rule**: Red Bear adapts to upstream, never the reverse

 # KWin — real cmake build of the KDE Wayland compositor/window manager.
 # null+8 Wayland crash is verified FIXED in qtwaylandscanner (commits
 # de2d74c37e + 882c2974ec). Cross-build still bounded by:
-#   - libepoxy-stub / libudev-stub: policy debt; real libepoxy/libudev
-#     recipes exist but source is not yet populated. Stub packages stage
-#     the cmake targets KWin links against (epoxy::epoxy, UDev::UDev).
-#     When real libepoxy and libudev get populated source, switch KWin's
-#     deps to those recipes and remove the stubs.
-#   - KF6Svg: KF6::Svg is not built on Redox. KWin's CMakeLists touches
-#     the target in optional paths; the recipe stubs it locally.
+#   - libepoxy: switched from stub to real libepoxy v6.0 2026 (2026-07-09).
+#     Provides epoxy::epoxy cmake target with real EGL/GLES function pointer
+#     dispatch, replacing the hardcoded-zero stub.
+#   - KF6Svg: built by local/recipes/kde/kf6-ksvg and consumed by KWin.
 #   - Sensors / UiTools: removed from CMakeLists.txt (these components
 #     are not yet in-tree for Redox; sed-removal keeps the cmake build
 #     bounded).
