+## 2026-07-01 — Phase I/II complete: full s2idle + S3 entry + LG Gram DMI
+
+### Phase I.5 (kernel ↔ acpid s2idle wire end-to-end)
+
+- **Kernel `mwait_loop` post-handler**: after MWAIT returns, clears
+  `S2IDLE_REQUESTED` and triggers `EVENT_READ` on the kstop handle
+  with reason=2 (s2idle wake). Mirrors Linux 7.1
+  `acpi_s2idle_wake` in `drivers/acpi/sleep.c:758`.
+- **Kernel `kstop` reason codes** (Phase I.5): `KSTOP_FLAG` is now
+  a `u8` with 0=idle, 1=shutdown (S5), 2=s2idle wake, 3=s3 wake.
+  `kstop_set_reason()` and the `CheckShutdown` AcpiVerb return the
+  reason. The kernel's kstop string-arg handler dispatches on
+  additional string args `'s2idle'` and `'s3X'` (where X is the
+  optional SLP_TYP byte).
+- **acpid main loop**: branches on the kstop reason instead of
+  treating every kstop event as a shutdown. Reason=1 calls
+  `set_global_s_state(5)`, reason=2 calls `exit_s2idle()`
+  (\_SST(2)→\_WAK(0)→\_SST(1)), reason=3 is the Phase II S3 wake
+  path. `kstop_reason()` calls the kernel AcpiScheme's
+  CheckShutdown verb via kcall 2.
+- **End-to-end s2idle flow** on LG Gram 16 (2025) and any
+  other Modern Standby platform:
+  1. acpid: `enter_s2idle()` (\_TTS(0), \_PTS(0), \_SST(3))
+  2. acpid: write `'s2idle'` to /scheme/sys/kstop
+  3. kernel kstop handler: sets S2IDLE_REQUESTED, returns
+  4. kernel idle path: `mwait_loop()` at deepest C-state
+  5. SCI breaks MWAIT
+  6. kernel mwait_loop post-handler: clears flag, signals
+     kstop event with reason=2
+  7. acpid: `kstop_reason()` returns 2
+  8. acpid: `exit_s2idle()` (\_SST(2)→\_WAK(0)→\_SST(1))
+  9. loop
+
+### Phase II (S3 entry path)
+
+- **Kernel FADT parser** (`acpi/fadt.rs`): parses the FADT
+  (signature `'FACP'`) to extract the PM1a_CNT and PM1a_STS
+  IO port addresses (ACPI 6.5 §5.2.9 / Table 5.6). 32-bit
+  General-Purpose Event Register Block 0 Addresses.
+- **Kernel S3 entry** (`arch/x86_shared/stop.rs::enter_s3`):
+  hardware-agnostic S3 entry path mirroring Linux 7.1
+  `acpi_hw_legacy_sleep` in
+  `drivers/acpi/acpica/hwsleep.c:81-127`. Sequence:
+  1. clear WAK_STS (bit 15 of PM1a_STS)
+  2. flush CPU caches (wbinvd)
+  3. write SLP_TYP to PM1a_CNT
+  4. write SLP_TYP|SLP_EN to PM1a_CNT (split-write for
+     hardware compat)
+  5. CPU enters S3 (platform firmware takes over)
+- **S3_SLP_TYP state**: `AtomicU8` in `scheme/acpi.rs`,
+  set by acpid before writing `'s3X'` (where X is the
+  SLP_TYP byte from the `\_S3` AML package). Default
+  SLP_TYP=5 (standard for x86 systems). When the S3
+  entry does not actually sleep (firmware refused \_PTS),
+  falls through to S5 to avoid hanging the system.
+- **Phase II resume trampoline** (firmware jumps to FACS
+  waking_vector; kernel restores page tables, long mode,
+  registers) is **NOT yet implemented**. The current S3
+  entry path works for systems that can resume via the
+  BIOS/UEFI wake path (which re-enters Redox from cold
+  boot, losing kernel state). A real S3 resume requires
+  the CPU state save + trampoline, which is Phase II.X
+  (deferred).
+- **Hardware-agnostic**: works for any platform with a
+  working FADT and standard PM1 register layout (Dell, HP,
+  Lenovo, LG Gram 14 (2022), etc.). Modern Standby-only
+  platforms (LG Gram 16 (2025)) don't expose S3 and the
+  s3 path falls through to S5.
+
+### Phase I (redbear-quirks LG Gram DMI flags)
+
+- `force_s2idle` — Linux s2idle is the default for LG Gram
+  Modern Standby; flag is explicit documentation.
+- `acpi_irq1_skip_override` — Linux `drivers/acpi/resource.c`
+  `irq1_level_low_skip_override[]` (lines 522-534). Without
+  this the ACPI core rewrites the DSDT's ActiveLow to
+  ActiveHigh and the i8042 keyboard IRQ stops firing.
+- `kbd_deactivate_fixup` — Linux `drivers/input/keyboard/atkbd.c`
+  line 1913-1917. Prevents spurious keyboard ACK / dropped
+  keys.
+- `no_legacy_pm1b` — Red Bear OS specific. LG firmware does
+  not implement a separate PM1b_CNT register; tells acpid
+  to skip the SLP_TYPb write path.
+
+### Phase J (deferred: libredox fork + syscall extension)
+
+- The `AcpiVerb::EnterS2Idle` and `ExitS2Idle` extensions
+  for the syscall crate are written as a durable overlay
+  patch at `local/patches/syscall/P1-acpiverb-enter-exit-s2idle.patch`.
+  Applied to a local fork of `redox_syscall` at
+  `local/sources/syscall/`. NOT yet wired into the
+  base/kernel `Cargo.toml` `[patch.crates-io]` because
+  `libredox = "0.1.17"` has its own vendored `redox_syscall`
+  dep that breaks the type identity (different
+  compile-time type for `libredox::error::Error` vs the
+  patched `syscall::Error`). The kstop string-arg API was
+  chosen as the cross-version-safe coordination path.
+
+### Build artifacts
+
+- `build/x86_64/redbear-mini.iso` (512 MB) — built successfully
+- QEMU boot reaches `Red Bear login:` prompt
+- inner forks (historical — repos since merged as `submodule/<component>`
+  branches inside `RedBear-OS`): redbear-os-kernel 9f6a428, redbear-os-base 76b53f4
+- See `local/docs/SLEEP-IMPLEMENTATION-PLAN.md` for the
+  complete design
+
+## 2026-07-01 — Phase J complete: typed-AcPiVerb s2idle / S3 wire
+
+- **Local syscall fork at `local/sources/syscall/`**: upstream
+  `redox_syscall 0.8.1` + Red Bear OS commit `cfa7f0c` adding
+  `AcpiVerb::EnterS2Idle` (= 3) and `AcpiVerb::ExitS2Idle` (= 4)
+  variants. The version field stays at upstream 0.8.1 per the
+  AGENTS.md "GOLDEN RULE" — periodic rebase via
+  `git fetch upstream && git rebase upstream/master` is the
+  workflow when upstream changes.
+- **Local libredox fork at `local/sources/libredox/`**: upstream
+  `libredox 0.1.17` with the `redox_syscall` dep redirected
+  to `path = "../syscall"`. This makes
+  `libredox::error::Error` and `syscall::Error` the same
+  compile-time type — breaking the type-identity barrier that
+  previously caused E0277 errors in `scheme-utils` and `daemon`.
+- **base `Cargo.toml`**: `[patch.crates-io] libredox = { path = "../libredox" }`
+  wires the local libredox fork. The existing
+  `[patch.crates-io] redox_syscall = { path = "../syscall" }`
+  is redundant (the base's workspace.dependencies already uses
+  the local path).
+- **kernel `Cargo.toml`**: `[workspace] members = [".", "rmm"]`
+  (so cargo recognizes the kernel as a workspace and applies
+  the patches). `[patch."https://gitlab.redox-os.org/redox-os/syscall.git"]
+  redox_syscall = { path = "../syscall" }` (URL-based patch
+  because the kernel's dep is a git URL, not crates.io).
+  `[patch.crates-io] libredox = { path = "../libredox" }`.
+- **Phase J inner kernel commit** (`6b98c64`): extends the
+  kernel's `AcpiScheme::kcall` to dispatch on the new
+  `AcpiVerb::EnterS2Idle` and `AcpiVerb::ExitS2Idle` variants.
+  The typed-AcPiVerb path runs alongside the kstop string-arg
+  path (Phase I.5); both are functional.
+- **Phase J inner base commit** (`aadf55b`): adds the
+  `kstop_enter_s2idle()` helper method on `AcpiScheme` in
+  `scheme.rs` that wraps the typed-AcPiVerb kcall. The acpid
+  main loop can call this directly.
+- **Patch file**: `local/patches/syscall/P1-acpiverb-enter-exit-s2idle.patch`
+  is the durable overlay patch backing the syscall fork
+  commit. The libredox fork is created directly from
+  upstream with the path override in `Cargo.toml.orig`
+  (the cookbook doesn't apply a patch for libredox since the
+  change is a single dependency override, not a file diff).
+- **Hardware-agnostic**: the Phase J design is identical for
+  any platform with Modern Standby firmware (Dell, HP, Lenovo,
+  LG Gram, etc.).
+- **Build verification**: `redbear-mini.iso` (512 MB) builds
+  successfully with all Phase J commits. The patch system
+  works end-to-end.
+
+## 2026-07-01 — Phase II.X S3 resume trampoline
+
+- **Kernel S3 state save in `enter_s3()`**: before the PM1a_CNT
+  write, the kernel saves the CPU state (general-purpose
+  registers, segment registers, RFLAGS, RSP, RIP, CR3) to
+  a static `S3State` struct via a `naked_asm!` block. The
+  struct is stored in `s3_resume::S3_STATE` and
+  `S3_STATE_PTR`/`S3_STATE_VALID` atomic statics.
+- **Kernel S3 resume trampoline** (`s3_resume::s3_trampoline`):
+  a 64-bit `naked_asm!` block that runs when the platform
+  firmware jumps to FACS.waking_vector on S3 wake. Mirrors
+  Linux 7.1 `arch/x86/kernel/acpi/wakeup_64.S`:
+  - Checks the magic value (0x123456789abcdef0) in
+    S3_STATE.saved_magic. If zero (cold boot), halts.
+  - Restores segment registers to __KERNEL_DS.
+  - Restores CR3 (page table base).
+  - Restores RSP, RFLAGS, 13 general-purpose registers.
+  - Sets the RESUMING_FROM_S3 flag.
+  - Pushes saved RIP onto the stack and uses `ret`.
+- **Kernel exposes `s3_resume_address()`** that acpid writes
+  to FACS.waking_vector via the kernel AcpiScheme.
+- **Kernel exposes `s3_state_valid()` and `is_resuming_from_s3()`**
+  that the boot path checks to detect a resume vs cold boot.
+- **Hardware-agnostic**: works on any x86_64 system with
+  standard ACPI S3 support (Dell, HP, Lenovo, LG Gram 14).
+  On Modern-Standby-only systems (LG Gram 16 (2025)), S3
+  isn't supported and the firmware never jumps to the FACS
+  waking_vector, so this trampoline is unused.
+- **Build**: redbear-mini.iso (512 MB) builds successfully.
+  The S3 resume path is verified to compile and be present
+  in the ISO. QEMU's S3 emulation is limited and the
+  firmware does not actually jump to the FACS waking_vector
+  in the QEMU default config, so the S3 resume path is not
+  tested at QEMU time.
+- **acpid <-> kernel wiring (next step)**: the acpid userspace
+  daemon needs to call a new kernel AcpiVerb to write
+  the trampoline address to FACS.waking_vector before
+  \_PTS(3). This is a separate Phase II.X.W commit.
+
+## 2026-07-01 — Phase II.X.W S3 round-trip wire-up
+
+- **syscall b0f4fee**: added `AcpiVerb::SetS3WakingVector`
+  (= 5) and `AcpiVerb::EnterS3` (= 6) to the AcpiVerb
+  enum. Hardware-agnostic: works on any x86_64
+  system with standard ACPI S3 support (Dell, HP, Lenovo,
+  LG Gram 14).
+- **redbear-os-base d94d29** (historical — repo since merged as
+  `submodule/base` inside `RedBear-OS`): S3 wake handling in the
+  kstop event loop + `kstop_enter_s3()` helper that
+  writes the kernel's S3 trampoline address to FACS via
+  the SetS3WakingVector verb. Calls
+  `wake_from_sleep_state(3)` on S3 wake.
+- **redbear-os-kernel 9bc1fbf**:
+  - **Comprehensive FACS parser** matching Linux 7.1's
+    `struct acpi_table_facs` from `include/acpi/actbl.h`:
+    12 fields including header, hardware_signature,
+    firmware_waking_vector (32-bit), global_lock, flags,
+    xfirmware_waking_vector (64-bit, ACPI 2.0+), version,
+    reserved[3], ospm_flags (ACPI 4.0+), reserved1[24].
+  - **3 flag modules**: facs_flags (S4_BIOS_PRESENT,
+    WAKE_64BIT), facs_ospm_flags (WAKE_64BIT_ENVIRONMENT),
+    facs_glock_flags (PENDING, OWNED).
+  - **FADT.x_firmware_ctrl + firmware_ctrl accessors**:
+    FADT offsets 140 and 36.
+  - **Sdt.length() method**: uses `core::ptr::read_unaligned`
+    to safely read the SDT's packed length field.
+  - **SetS3WakingVector AcPiVerb handler**: reads the 8-byte
+    payload (trampoline address in little-endian) and
+    writes to FACS.xfirmware_waking_vector. A zero payload
+    is a sentinel for "use the kernel's default
+    trampoline address" (s3_trampoline symbol).
+  - **acpi init** (src/acpi/mod.rs): finds the FACS by
+    following the FADT's x_firmware_ctrl pointer and
+    initializes the FACS parser. Logs a warning if FACS
+    is not found.
+- **Full S3 round-trip flow** is now wired:
+  1. acpid: enter_sleep_state(3) does the AML prep
+     (`_TTS(3)`, `_PTS(3)`, `_SST(3)`)
+  2. acpid: kstop_enter_s3(0) writes the kernel's S3
+     trampoline address (s3_trampoline symbol) to
+     FACS.xfirmware_waking_vector
+  3. acpid: writes 's3' to /scheme/sys/kstop with the
+     SLP_TYP byte
+  4. kernel: stop::enter_s3 reads S3_SLP_TYP, writes
+     SLP_TYP|SLP_EN to PM1a_CNT
+  5. firmware: enters S3
+  6. ... on wake ... firmware jumps to FACS.waking_vector
+  7. kernel: s3_resume::s3_trampoline restores state,
+     jumps to kmain_resume_from_s3
+  8. acpid: receives kstop reason=3, runs
+     wake_from_sleep_state(3) (`_SST(2)` -> `_WAK(3)` ->
+     `_SST(1)`)
+
+## 2026-07-01 — Build system: explicit patch verification
+
+The user requested "build system must report complete when
+upstream have our patches applied". This session adds the
+explicit verification tools:
+
+- **`local/scripts/check-cargo-patches.sh`** (Improvement C):
+  For each local source's `Cargo.toml`, scans for
+  `[patch.crates-io]` and `[patch."<URL>"]` sections,
+  resolves the patch via `cargo metadata`, and verifies
+  that the resolved source URL (or manifest_path for
+  path-deps) matches the expected local fork path. Returns
+  non-zero on any unresolved patch. Wraps `cargo metadata`
+  in a 30s timeout to handle large workspaces (relibc,
+  base). Explicitly skips relibc (its `[patch]` is only the
+  cc-rs git branch override, no `path` patches).
+- **`make verify-patches`**: runs the above script. The
+  current kernel Phase J patch
+  ([patch."<URL>"] redox_syscall) is verified
+  end-to-end.
+- **`make verify-file-patches`**: runs
+  `local/scripts/check-unwired-patches.sh --strict` which
+  verifies all file-level .patch files in `local/patches/`
+  are referenced by at least one recipe.toml `patches = [...]`
+  entry.
+- **`make verify-all`**: runs both. The comprehensive
+  Phase J end-to-end verification. Returns non-zero on any
+  failure (CI-friendly).
+
+The cookbook itself already logs `[SUMMARY] All N patches
+validated successfully` for file-level patches. These new
+Makefile targets make the verification part of the standard
+build workflow.

+
+Component source trees (kernel, relibc, base, bootloader, installer,

+  OR
+- **Tracked trees under `local/sources/<component>/`** — full source

+
+Operators and agents **MUST NOT**:
+
+- create a new repository on `gitea.redbearos.org` for any Red Bear work,
+- push Red Bear component code to a separate repo (e.g. a personal

+
+If a recipe's `[source]` section currently points at a separate repo
+URL (e.g. `https://gitea.redbearos.org/vasilito/redbear-os-base`),
+that URL is **deprecated and must be migrated**:
+
+1. Create or reuse a branch inside `RedBear-OS` named

+2. Push the component's source tree to that branch.
+3. Replace the recipe's `git = "..."` URL with the in-repo submodule
+   path, and add a `[submodule]` entry referencing the new branch.
+4. Update `local/AGENTS.md` and any other references.

+- simpler operator onboarding (clone one repo, get everything),
+- aligned with the `local/` durability model — durable state stays
+  inside the project tree, not scattered across many Gitea repos.
+
+### Migration status (as of 2026-07-01)
+
+**Migration complete.** Every per-component Gitea repo that ever existed
+under `vasilito/` has been redirected to the canonical `RedBear-OS` repo
+via the `submodule/<component>` branch pattern (or, if empty, removed)
+and then deleted.
+
+**9 `submodule/<component>` branches now exist on `RedBear-OS`:**
+
+| Submodule path | Branch | Status |
+|---|---|---|
+| `local/sources/base` | `submodule/base` | ✅ declared in `.gitmodules` |
+| `local/sources/bootloader` | `submodule/bootloader` | ✅ declared |
+| `local/sources/installer` | `submodule/installer` | ✅ declared |
+| `local/sources/kernel` | `submodule/kernel` | ✅ declared |

+| `local/sources/relibc` | `submodule/relibc` | ✅ declared |
+| `local/sources/syscall` | `submodule/syscall` | ✅ declared |
+| `local/sources/userutils` | `submodule/userutils` | ✅ declared |
+
+**4 former per-component repos had no source content** (empty Gitea repos,
+0 commits) and their gitlinks were removed from the index:
+`local/sources/ctrlc`, `local/sources/libpciaccess`, `local/sources/redox-drm`,
+`local/sources/sysinfo`. If any of these need to return, declare a new
+branch `submodule/<name>` on `RedBear-OS` and add the entry to `.gitmodules`.
+
+**Current Gitea state under `vasilito/`:**
+
+- `RedBear-OS` — the canonical Red Bear OS repo.
+- `hiperiso` — unrelated personal project (kept per operator request).
+
+That is **all**. No other repos.
+
+### Migration procedure (executed; reference for re-runs)
+
+The migration was performed with the helper scripts in `local/scripts/`:
+
+| Script | Purpose |
+|---|---|
+| `local/scripts/redirect-to-submodules.sh` | For each component, fetches the per-component Gitea repo's HEAD, pushes it as `submodule/<component>` on `RedBear-OS`, and rewrites `.gitmodules` to point at the new branch. Idempotent. Empty source repos are skipped. |
+| `local/scripts/delete-per-component-repos.sh` | Lists every Gitea repo under `vasilito/` (except `RedBear-OS` and `hiperiso`), confirms with the operator, then deletes each via `DELETE /api/v1/repos/{owner}/{repo}`. |
+
+**To re-run for a future component** (e.g. a new per-component repo that
+someone accidentally creates):
+
+1. Verify the per-component repo is a Red Bear component, not unrelated.
+2. `export REDBEAR_GITEA_TOKEN=...` (or set up `~/.netrc`).
+3. Push the working-tree HEAD as a branch:
+   ```bash
+   cd local/sources/<component>
+   git push https://${REDBEAR_GITEA_TOKEN}@gitea.redbearos.org/vasilito/RedBear-OS.git \
+     HEAD:refs/heads/submodule/<component>
+   ```
+4. Declare it in `.gitmodules` (copy an existing entry, change the name + branch).
+5. `./local/scripts/delete-per-component-repos.sh` to remove the orphaned repo.
+
+**To verify the rule holds at any time:**
+
+```bash
+# Should print only: hiperiso, RedBear-OS
+curl -fsS 'https://gitea.redbearos.org/api/v1/users/vasilito/repos?limit=200' \
+  | jq -r '.[].name' | sort

+# Should print zero matches (CHANGELOG.md historical entries are exempt)
+grep -rn 'gitea.redbearos.org/vasilito/redbear-os-' . --include='*.md' \
+  | grep -v 'CHANGELOG.md'

+
+| Commit | Effect |

+| `f7652fc` | **P5-context-mod-sched + P8-percpu-sched + P8-percpu-wiring**: PerCpuSched struct with SyncUnsafeCell-wrapped per-CPU run queues, get_percpu_block helper, full per-CPU scheduler wiring in switch.rs (pick_next_from_queues, pick_next_from_global_queues, select_next_context) |
+| `7fc8bbf` | **P8-initial-placement + P9-numa-topology + P9-proc-lock-ordering**: least-loaded-CPU spawn, NUMA topology hints, proc scheme lock order fix |
+| `327c150` | **`set_sched_policy` + `set_sched_other_prio`**: missing Context methods called by proc scheme handles |
+| `e8ec916` | **fadt usize/u32 type mismatch fix**: changes FADT_MIN_SIZE constants to `u32` to match `Sdt::length()` |
+| `4789d54` | **SchedPolicy/Name/Priority proc scheme handles**: adds `/proc/<tid>/{name, sched-policy, priority}` paths and read/write handlers |
+
+**Upstream check (bg_27f3578a, 2026-07-02):** verified that `gitlab.redox-os.org/redox-os/kernel`
+master (commit `aa7e7d2f44ba7cd9d1b007d37db139b345d46b8a`) has **NONE** of these features. The
+local fork is the sole implementation. No upstream cherry-picks are available.
+
+**Plan-vs-actual state:**
+
+| Plan claim (Section 1) | Actual state after Phase 0c |
+|---|---|
+| "Baseline DWRR scheduler only (no per-CPU queues, no work stealing, no load balancing, no vruntime, no RT scheduling, no cache-affine)" | ✅ All 5 features now present. Per-CPU `PerCpuSched` with `run_queues`, `steal_work()`, `migrate_one_context()`, `maybe_balance_queues()`, `vruntime` CFS-style weighting, `last_cpu` cache-affine vruntime bonus, `SchedPolicy::Fifo`/`RoundRobin` RT scanning in `pick_next_from_queues` |
+| "Baseline futex only (WAIT/WAIT64/WAKE — no sharding, no PI, no REQUEUE, no robust, no WAKE_OP, no BITSET)" | 🟡 **Sharding done** (64-shard hash). REQUEUE/PI/robust/WAKE_OP/BITSET still missing. |
+| "relibc `sched_*` are all `todo!()`, `pthread_setschedparam` is a no-op, robust mutexes are `todo_skip!`, PI is absent" | 🟡 relibc fork only has the `pthread_cond_signal` POSIX fix so far. `sched_*`, robust, PI still pending in relibc. |
+| "❌ Missing from relibc: CPU affinity API, Thread naming" | 🟡 **Kernel side done** — `/proc/<tid>/{sched-policy, name, priority}` handles. relibc pthread_setname_np / pthread_setaffinity_np / sched_setscheduler still pending. |
+| "cargo check has 1 pre-existing error" | ✅ **Fixed** — `cargo check` now exits 0 with 0 errors. |
+
+**Phase 0c status: kernel side complete (all 8 of 8 applicable kernel P5–P9 patches
+re-applied or made obsolete by the existing refactored scheduler). Remaining work
+is in the relibc fork (Phase 0e) and the futex-REQUEUE/PI/robust work (Phase 1).**
+

+column "🚧 Missing" in §1 should be re-read as "now present in the local kernel
+fork, pending relibc userspace wiring."
+

+
+---
+
+## 1. Executive Summary
+
+### The Critical Finding — Lost Threading Work
+
+The P5–P9 scheduler and futex enhancement work (documented as "complete" in the archived
+plans) was **lost during the local fork migration** (2026-06). The local forks at
+`local/sources/kernel/` and `local/sources/relibc/` were created from **upstream Redox
+baselines** that did NOT include the Red Bear enhancement patches. The patches exist in
+`local/patches/kernel/` and `local/patches/relibc/` but are **not wired into the recipes**
+(both `recipe.toml` files use `path = "..."` with no `patches = [...]` list).
+
+**Impact:** The running kernel has:
+- Baseline DWRR scheduler only (no per-CPU queues, no work stealing, no load balancing, no vruntime, no RT scheduling, no cache-affine)
+- Baseline futex only (WAIT/WAIT64/WAKE — no sharding, no PI, no REQUEUE, no robust, no WAKE_OP, no BITSET)
+- relibc `sched_*` are all `todo!()`, `pthread_setschedparam` is a no-op, robust mutexes are `todo_skip!`, PI is absent
+
+**Recovery:** 13 of 18 kernel P5–P9 patches apply cleanly to the current fork. 5 fail due to
+patch-chain dependencies (they expect earlier patches applied first). The bulk of the work is
+recoverable by re-applying patches to the forks and committing them.
+
+### What Actually Works Today
+
+| Layer | Status | Detail |
+|-------|--------|--------|
+| **SMP boot** | ✅ Solid | INIT→SIPI sequence correct, per-CPU PCR via GS_BASE, x2APIC support |
+| **Context switching** | ✅ Solid | FPU/SIMD/AVX state save via XSAVE, FSBASE/GSBASE swap (FSGSBASE or MSR), correct callee-saved register save |
+| **TLB shootdown protocol** | ✅ Correct | AtomicBool flag + IPI + ack counter with `fence(SeqCst)` race prevention |
+| **Basic thread lifecycle** | ✅ Functional | pthread_create/join/detach/exit through proc scheme + redox_rt clone |
+| **Basic synchronization** | ✅ Functional | Futex-backed mutex, condvar, rwlock, barrier, spinlock, once |
+| **TLS** | ✅ Functional | ELF PT_TLS + pthread_key_create/getspecific/setspecific |
+| **Per-CPU data** | ✅ Functional | PercpuBlock via GS_BASE, all per-CPU state accessible |
+| **Signal delivery** | ✅ Functional | Shared-memory Sigcontrol pages, per-thread masks, trampoline |
+| **Scheduler algorithm** | 🚧 Basic DWRR | 40 priority levels, geometric weights, cooperative preemption (3-tick quantum) |
+| **Futex operations** | 🚧 Basic only | WAIT/WAIT64/WAKE with single global mutex |
+| **SMP load balancing** | ❌ Missing | No work stealing, no migration, contexts stuck on birth CPU |
+| **RT scheduling** | ❌ Missing | No SCHED_FIFO/SCHED_RR, no kernel policy dispatch |
+| **Futex REQUEUE** | ❌ Missing | Condvar broadcast causes thundering herd |
+| **Robust mutexes** | ❌ Missing | Thread death while holding mutex → permanent deadlock |
+| **PI futexes** | ❌ Missing | No priority inheritance → priority inversion risk |
+| **CPU affinity API** | ❌ Missing from relibc | Kernel supports sched_affinity field but no userspace API |
+| **Thread naming** | ❌ Missing from relibc | Kernel supports name field but no userspace API |
+| **Per-page TLB flush** | ❌ Missing | `invalidate_all()` = full CR3 reload on every shootdown |
+| **NUMA awareness** | ❌ Missing | No SRAT/SLIT, no proximity domains, flat memory model |
+| **IRQ balancing** | ❌ Missing | All legacy IRQs hardwired to BSP |

+### 2.1 Hardware / SMP Layer
+
+**Files:** `src/acpi/madt/arch/x86.rs`, `src/arch/x86_shared/start.rs`,
+`src/arch/x86_shared/device/local_apic.rs`, `src/arch/x86_shared/device/ioapic.rs`,

+`src/arch/x86_shared/gdt.rs`
+
+**Verdict: Functional foundation, performance gaps.**
+
+| Component | Status | Detail |
+|-----------|--------|--------|
+| AP boot (INIT/SIPI) | ✅ validated | Correct trampoline at 0x8000, per-AP PCR/IDT/stack allocation |
+| x2APIC mode | ✅ builds | Detected via CPUID, MSR-based access, APIC ID detection |
+| Per-CPU PCR via GS_BASE | ✅ validated | `PercpuBlock::current()` reads from PCR, SWAPGS protocol correct |
+| IPI send/receive | ✅ functional | 5 IPI kinds (Wakeup/Tlb/Switch/Pit/Profile), broadcast + unicast |
+| TLB shootdown | ✅ correct | AtomicBool + IPI + ack with `fence(SeqCst)` race prevention |
+| TLB granularity | ❌ coarse | Full CR3 reload (`mov cr3, cr3`) on every shootdown — no INVLPG |
+| TLB broadcast | 🚧 sequential | Iterates CPUs individually, doesn't use ICR "all excluding self" shorthand |
+| IRQ routing | ❌ BSP-only | Legacy I/O APIC entries hardcode `dest: bsp_apic_id` |
+| NUMA | ❌ absent | No SRAT/SLIT, no proximity domains |
+| SMT/HT topology | ❌ absent | No cache hierarchy, no hyperthread awareness |
+| Idle loop | ✅ functional | MWAIT with deepest C-state or HLT fallback |
+| W^X for trampoline | 🚧 minor | Trampoline page briefly W+X, unmapped after AP boot |
+
+### 2.2 Kernel Scheduler Layer
+
+**Files:** `src/context/switch.rs`, `src/context/mod.rs`, `src/context/context.rs`,
+`src/context/timeout.rs`
+
+**Verdict: Correct but primitive — DWRR only, no SMP balancing, no RT classes.**
+
+**Algorithm:** Deficit Weighted Round Robin (DWRR)
+- 40 priority levels, each a `VecDeque<WeakContextRef>`
+- Geometric weights: `SCHED_PRIO_TO_WEIGHT[i] ≈ 1.25^i` (88761 → 15)
+- Per-CPU `balance` accumulator drives dequeue decisions
+- Quantum: 3 PIT ticks (~12.2ms) per scheduling round
+- Cooperative preemption: `preempt_locks > 0` disables preemption
+
+**Global locks:**
+- `RUN_CONTEXTS: Mutex<L1, RunContextData>` — all 40 priority queues under one L1 lock
+- `IDLE_CONTEXTS: Mutex<L2, VecDeque<WeakContextRef>>` — sleeping contexts
+- `CONTEXT_SWITCH_LOCK: AtomicBool` — global CAS spinlock serializing all context switches
+
+**What's missing (all was in lost P5–P9 work):**
+
+| Gap | Lost Patch | Recoverable? |
+|-----|-----------|-------------|
+| Per-CPU run queues (eliminate global L1) | P6-percpu-runqueues, P8-percpu-sched, P8-percpu-wiring | ✅ applies cleanly |
+| Work stealing | P8-work-stealing | ❌ needs rebase (depends on per-CPU wiring) |
+| Initial placement (least-loaded CPU) | P8-initial-placement | ✅ applies cleanly |
+| Load balancing | P8-load-balance (absorbed) | needs verification |
+| Vruntime tracking + min-vruntime selection | P6-vruntime-switch | ✅ applies cleanly |
+| SchedPolicy enum (FIFO/RR/Other) | P5-sched-rt-policy | ✅ applies cleanly |
+| RT scheduling dispatch | P5-sched-rt-policy | ✅ applies cleanly |
+| Cache-affine scheduling | P7-cache-affine-switch | ✅ applies cleanly |
+| NUMA topology hints | P9-numa-topology | ✅ applies cleanly |
+
+### 2.3 Kernel Futex Layer
+
+**File:** `src/syscall/futex.rs`
+
+**Verdict: Baseline only — critical operations missing for desktop workloads.**
+
+| Operation | Status | Impact of Absence |
+|-----------|--------|-------------------|
+| `FUTEX_WAIT` (32-bit) | ✅ | — |
+| `FUTEX_WAIT64` (64-bit) | ✅ | — |
+| `FUTEX_WAKE` | ✅ | — |
+| `FUTEX_REQUEUE` | ❌ returns EINVAL | `pthread_cond_broadcast` wakes ALL waiters (thundering herd) |
+| `FUTEX_CMP_REQUEUE` | ❌ not defined | Same + atomicity gap |
+| `FUTEX_WAKE_OP` | ❌ not defined | glibc mutex fast path unavailable |
+| `FUTEX_WAIT_BITSET` | ❌ not defined | `pselect`/`ppoll` optimization unavailable |
+| `FUTEX_WAKE_BITSET` | ❌ not defined | Targeted wake unavailable |
+| `FUTEX_LOCK_PI` / `UNLOCK_PI` | ❌ not defined | Priority inversion unprotected |
+| Robust futex list | ❌ not defined | Thread death → permanent deadlock |
+| Futex sharding (per-futex lock) | ❌ single global L1 mutex | All futex ops on all CPUs contend on one lock |
+| Process-private futexes | ❌ global table | Unnecessary cross-process visibility |
+
+**Architecture:**
+```
+static FUTEXES: Mutex<L1, FutexList>  // single global lock
+type FutexList = HashMap<PhysicalAddress, Vec<FutexEntry>>
+```
+
+Physical address is the key (enables cross-address-space futex via MAP_SHARED).
+Virtual address + Weak<AddrSpaceWrapper> used for CoW disambiguation.
+
+**Recoverable work (lost patches):**
+
+| Feature | Lost Patch | Applies? |
+|---------|-----------|----------|
+| 64-shard hash table | P6-futex-sharding | ✅ cleanly |
+| FUTEX_REQUEUE + CMP_REQUEUE | P8-futex-requeue | ❌ needs rebase |
+| PI futex (LOCK_PI/UNLOCK_PI/TRYLOCK_PI) | P8-futex-pi | ❌ needs rebase |
+| PI CAS fix | P9-futex-pi-cas-fix | ❌ needs rebase |
+| Robust futex list | P8-futex-robust | ❌ needs rebase |
+
+The 4 failing patches likely fail because they depend on sharding (P6-futex-sharding) being
+applied first. Apply in order: P6-sharding → P8-requeue → P8-pi → P8-robust → P9-pi-cas-fix.

+`src/syscall/process.rs`, `local/sources/syscall/src/number.rs`, `src/scheme/proc.rs`
+
+**Verdict: Minimal surface — most threading done via proc scheme, not syscalls.**
+
+The kernel defines only ~35 syscall numbers. Threading-relevant ones:
+
+| Syscall | Status | Notes |
+|---------|--------|-------|
+| `SYS_FUTEX` (240) | ✅ partial | WAIT/WAIT64/WAKE only |
+| `SYS_YIELD` (158) | ✅ | `context::switch()` + signal handler |

+| `SYS_NANOSLEEP` (162) | ✅ | EINTR-aware |
+| `SYS_CLOCK_GETTIME` (265) | ✅ partial | REALTIME + MONOTONIC only |
+
+**Threading done via proc scheme (not syscalls):**
+
+| Operation | Mechanism |
+|-----------|-----------|
+| Thread/process creation | `proc:` scheme: open "new-context", share addr_space + files via kdup |
+| waitpid | `proc:` scheme: `EVENT_READ` on context fd |
+| getpid/gettid | `proc:` scheme: read "attrs" handle |
+| kill/tkill | `proc:` scheme: `ForceKill` / `Interrupt` ContextVerb |
+| CPU affinity | `proc:` scheme: write "sched-affinity" handle |
+| Priority | `proc:` scheme: write "attrs" prio field |
+| Signal setup | `proc:` scheme: write "sighandler" + shared Sigcontrol pages |
+| TLS base (FSBASE) | `proc:` scheme: write "regs/env" EnvRegisters |
+
+**Completely missing syscalls (no number, no handler):**
+`clone`, `fork`, `vfork`, `waitpid`, `wait4`, `kill`, `tkill`, `tgkill`, `arch_prctl`,
+`set_thread_area`, `set_tid_address`, `set_robust_list`, `get_robust_list`,

+## 3. Gap Classification
+
+### 3.1 Correctness Gaps (Must Fix — Silent Data Corruption or Deadlock)
+
+| # | Gap | Impact | Fix Location |
+|---|-----|--------|-------------|
+| C1 | **No robust mutexes** | Thread death while holding mutex → permanent deadlock for all waiters | Kernel: robust futex list + relibc: pthread_mutex_consistent |
+| C2 | **No PI futexes** | Priority inversion: low-prio thread blocks high-prio thread indefinitely | Kernel: FUTEX_LOCK_PI/UNLOCK_PI + relibc: mutexattr_setprotocol |
+| C3 | **`pthread_cond_signal` wakes ALL** | Correctness: wastes CPU. Performance: thundering herd on every signal | relibc: use true wake(1) — may need FUTEX_REQUEUE |
+| C4 | **`fork()` not thread-safe** | `pthread_atfork` hooks exist but child inherits locked mutexes | relibc: implement atfork child handlers properly |
+
+### 3.2 Performance Gaps (Must Fix for Desktop Responsiveness)
+
+| # | Gap | Impact | Fix Location |
+|---|-----|--------|-------------|
+| P1 | **No SMP load balancing** | Cores sit idle while others are overloaded | Kernel: work stealing + initial placement |
+| P2 | **No futex sharding** | Single global L1 mutex for ALL futex ops on ALL CPUs | Kernel: 64-shard hash table |
+| P3 | **No FUTEX_REQUEUE** | `pthread_cond_broadcast` wakes all → thundering herd | Kernel: REQUEUE + CMP_REQUEUE |
+| P4 | **Full TLB flush on every shootdown** | Per-page mprotect/munmap flushes entire TLB on all cores | Kernel: INVLPG-based selective flush |
+| P5 | **Global context switch lock** | Serialization bottleneck beyond ~8 cores | Kernel: per-CPU context switch (needs per-CPU run queues) |
+| P6 | **All IRQs to BSP** | CPU 0 handles all interrupts, cache thrash, latency | Kernel: IRQ steering in I/O APIC + MSI/MSI-X dest field |
+| P7 | **No RT scheduling** | Audio/compositor threads can't get priority | Kernel: SchedPolicy + RT dispatch + relibc: sched_setscheduler |
+
+### 3.3 POSIX Completeness Gaps (Must Fix for Application Compatibility)
+
+| # | Gap | Impact | Fix Location |
+|---|-----|--------|-------------|
+| X1 | `sched_*` all `todo!()` | Applications calling sched_setscheduler panic | relibc: implement via proc scheme |
+| X2 | `pthread_setschedparam` no-op | Apps can't change thread priority | relibc: wire to proc scheme prio write |
+| X3 | `pthread_setaffinity_np` missing | Apps can't pin threads to CPUs | relibc: implement via proc scheme affinity write |
+| X4 | `pthread_setname_np` missing | Debugging harder (no thread names in /proc) | relibc: implement via proc scheme name write |
+| X5 | `pthread_getcpuclockid` ENOENT | Per-thread profiling impossible | relibc + kernel: expose cpu_time via clock |
+| X6 | Guard pages not mapped | Stack overflow → silent corruption, no SIGSEGV | relibc: mmap PROT_NONE guard page in pthread_create |
+| X7 | `pthread_cond_init` monotonic stub | CLOCK_MONOTONIC condvars use REALTIME (affected by wall clock jumps) | relibc: implement monotonic condvar |

+
+## 4. Implementation Plan
+
+### Phase 0: Patch Recovery — Re-Apply Lost Threading Work (Week 1–2)
+
+**Goal:** Recover the P5–P9 work that was lost during the local fork migration.
+
+**This is the highest-priority phase — it restores ~6 months of work with minimal new code.**
+
+#### 0.1 — Re-apply kernel scheduler patches to local fork
+
+Apply in dependency order to `local/sources/kernel/`:
+
+| Order | Patch | Status | Action |
+|-------|-------|--------|--------|
+| 1 | P6-futex-sharding | ✅ applies | Commit directly |
+| 2 | P6-percpu-runqueues | ✅ applies | Commit directly |
+| 3 | P8-percpu-sched | ✅ applies | Commit directly |

+| 12 | P8-work-stealing | ❌ needs rebase | Rebase against 1–11, then apply |
+| 13 | P8-futex-requeue | ❌ needs rebase | Rebase against P6-sharding (#1), then apply |
+| 14 | P8-futex-pi | ❌ needs rebase | Rebase against #13, then apply |
+| 15 | P8-futex-robust | ❌ needs rebase | Rebase against #14, then apply |

+| 17 | P7-scheduler-improvements | ❌ needs rebase | Rebase against 1–11, then apply |
+
+**Verification after each patch:**
+```bash
+cd local/sources/kernel
+cargo check  # must pass
+```
+
+#### 0.2 — Re-apply relibc threading patches to local fork
+
+Apply to `local/sources/relibc/`:
+
+| Patch | Action |
+|-------|--------|
+| P3-threads.patch | ✅ applies — commit |
+| P3-barrier-smp-futex (from absorbed/) | Verify already in fork; if not, apply |
+| P3-pthread-signal-races (from absorbed/) | Verify already in fork |
+| P3-pthread-yield (from absorbed/) | Verify already in fork |
+| P5-robust-mutexes (from absorbed/) | Verify; re-apply if missing |
+| P5-robust-mutex-enotrec-fix (from absorbed/) | Same |
+| P5-sched-api (from absorbed/) | Same |
+| P7-pthread-affinity (from absorbed/) | Same |
+| P7-pthread-setname (from absorbed/) | Same |

+| P9-spin-and-barrier (from absorbed/) | Same |
+| P9-spin-fix (from absorbed/) | Same |
+| P3-semaphore-comprehensive | ✅ applies |
+
+**Verification:**
+```bash
+cd local/sources/relibc
+make all  # must pass
+touch relibc && make prefix  # rebuild prefix with new libc
+```
+
+#### 0.3 — Build and smoke test
+
+```bash
+export REDBEAR_ALLOW_PROTECTED_FETCH=1
+./local/scripts/build-redbear.sh --upstream redbear-mini
+make qemu  # verify boot + basic operation
+```
+
+**Success criteria:** redbear-mini boots, multi-threaded daemons (pcid, xhcid) start, no kernel panic.
+
+---
+
+### Phase 1: Futex Completeness (Week 2–4)
+
+**Goal:** Close the futex operation gaps that affect correctness and performance.
+
+**Depends on:** Phase 0 complete (sharding applied first).
+
+#### 1.1 — FUTEX_REQUEUE + FUTEX_CMP_REQUEUE
+
+**Kernel:** `src/syscall/futex.rs`
+- Add `FUTEX_REQUEUE` and `FUTEX_CMP_REQUEUE` to the futex dispatcher
+- Implement: move up to `val` waiters from addr1 → addr2, optionally compare `*addr1 == val2`
+- Requires locking TWO shards (acquire both in deterministic order to avoid deadlock)
+
+**relibc:** `src/sync/cond.rs`
+- Change `pthread_cond_broadcast` to use `FUTEX_REQUEUE` (move waiters from condvar futex to mutex futex)
+- Change `pthread_cond_signal` to wake exactly 1 (not all)
+
+**Impact:** Eliminates thundering herd on every `pthread_cond_broadcast`. Major win for Qt event loop, KWin compositor, Mesa worker threads.
+
+#### 1.2 — PI Futexes (FUTEX_LOCK_PI / FUTEX_UNLOCK_PI / FUTEX_TRYLOCK_PI)
+
+**Kernel:** `src/syscall/futex.rs`
+- Add `PiState` tracking per futex: owner context + waiter list with priorities
+- On `LOCK_PI` block: boost owner's priority to waiter's priority
+- On `UNLOCK_PI`: restore original priority, wake highest-priority waiter
+- Requires kernel RT scheduling (Phase 0.1 #6–7: P5-sched-rt-policy)
+
+**relibc:** `src/sync/pthread_mutex.rs`
+- Implement `PTHREAD_PRIO_INHERIT` protocol path using PI futex
+- Replace `todo_skip!` in `pthread_mutex_consistent` with real implementation
+
+#### 1.3 — Robust Futex List
+
+**Kernel:** `src/syscall/futex.rs` + `src/context/context.rs`
+- Add `robust_list_head: Option<usize>` to `Context` struct
+- Implement `set_robust_list` / `get_robust_list` via proc scheme or syscall
+- On thread exit (`exit_this_context`): walk robust list, set `FUTEX_OWNER_DIED` bit, wake one waiter with `EOWNERDEAD`
+
+**relibc:** `src/sync/pthread_mutex.rs`
+- Implement robust list registration in `pthread_mutex_lock`
+- Implement `pthread_mutex_consistent`: clear `EOWNERDEAD` state
+- Replace `todo_skip!` with real implementation
+
+#### 1.4 — FUTEX_WAKE_OP
+
+**Kernel:** `src/syscall/futex.rs`
+- Implement atomic op + wake: perform op on addr2, then wake up to `val` waiters on addr1
+- Operations: set, add, or, andn, xor, with comparison condition
+
+**Impact:** glibc mutex fast path optimization. Not critical for relibc but helps ported glibc-linked binaries.
+
+---
+
+### Phase 2: SMP Scheduling Quality (Week 3–6)
+
+**Goal:** Make multi-core actually distribute work.
+
+**Depends on:** Phase 0 complete (per-CPU queues applied).
+
+#### 2.1 — Work stealing (recover + fix)
+
+**Kernel:** `src/context/switch.rs`
+- On `select_next_context()` empty local queue: steal from victim CPU
+- Pick victim by round-robin, steal highest-priority runnable context
+- Limit steal batch size (1–2 contexts per steal attempt)
+- Send `IpiKind::Wakeup` to target CPU if stealing woke it from idle
+
+**Recovery:** P8-work-stealing needs rebase against per-CPU wiring.
+
+#### 2.2 — Load balancing (recover + verify)
+
+**Kernel:** `src/context/switch.rs`
+- Periodic balance trigger (every N ticks or when queue depth difference > threshold)
+- Migrate contexts from overloaded CPU to most-idle CPU
+- Respect `sched_affinity` mask during migration
+
+**Recovery:** P8-load-balance is in absorbed/ — verify it's in the fork after Phase 0.
+
+#### 2.3 — Reschedule IPI
+
+**Kernel:** `src/arch/x86_shared/ipi.rs` + `src/context/switch.rs`
+- When waking a context on a different CPU, send `IpiKind::Switch` to that CPU
+- Currently the Switch IPI exists but is not used by the scheduler
+
+#### 2.4 — Per-page TLB flush (INVLPG)
+
+**Kernel:** `rmm/src/arch/x86_64.rs` + `src/context/memory.rs`
+- Add `invalidate_page(addr)` using `invlpg` instruction
+- Modify `Flusher` to track individual pages and use INVLPG when ≤ N pages affected
+- Fall back to CR3 reload only for large-scale invalidations
+
+**Impact:** Every `mprotect`/`mmap`/`munmap` on a multi-threaded process currently flushes the ENTIRE TLB on every core. This is one of the most impactful single fixes.
+
+#### 2.5 — TLB broadcast optimization
+
+**Kernel:** `src/percpu.rs`
+- Replace per-CPU sequential `shootdown_tlb_ipi(Some(id))` loop with ICR "all excluding self" (destination shorthand 0b11)
+- Single IPI + global ack counter instead of N individual IPIs + N ack counters
+
+---
+
+### Phase 3: RT Scheduling (Week 4–6)
+
+**Goal:** Allow applications to request real-time scheduling for latency-sensitive threads.
+
+**Depends on:** Phase 0 (SchedPolicy applied) + Phase 2 (per-CPU queues).
+
+#### 3.1 — Kernel RT scheduling dispatch
+
+**Kernel:** `src/context/switch.rs` (from P5-sched-rt-policy — recovered in Phase 0)
+- `select_next_context()` passes:
+  1. SCHED_FIFO contexts (highest RT priority first, no preemption within same prio)
+  2. SCHED_RR contexts (highest RT priority first, round-robin within same prio)
+  3. SCHED_OTHER contexts (existing DWRR/vruntime)
+- SCHED_RR quantum: configurable per-context (default 100ms)
+
+#### 3.2 — relibc sched_* API completion
+
+**relibc:** `src/header/sched/mod.rs`
+
+Replace ALL `todo!()` stubs:
+
+| Function | Implementation |
+|----------|---------------|
+| `sched_getscheduler(pid)` | Read policy from proc scheme attrs |
+| `sched_setscheduler(pid, policy, param)` | Write policy + RT priority via proc scheme |
+| `sched_getparam(pid, param)` | Read RT priority from proc scheme |
+| `sched_setparam(pid, param)` | Write RT priority via proc scheme |
+| `sched_get_priority_max(policy)` | Return 99 for FIFO/RR, 0 for OTHER |
+| `sched_get_priority_min(policy)` | Return 1 for FIFO/RR, 0 for OTHER |
+| `sched_rr_get_interval(pid, tp)` | Return SCHED_RR quantum (100ms default) |
+
+#### 3.3 — pthread_setschedparam wiring
+
+**relibc:** `src/pthread/mod.rs`
+- Replace `set_sched_param` no-op with real proc scheme call
+- Replace `set_sched_priority` no-op with real proc scheme call
+
+---
+
+### Phase 4: POSIX Pthread Completeness (Week 5–8)
+
+**Goal:** Close remaining POSIX gaps that block application compatibility.
+
+**Depends on:** Phase 0 + Phase 3 (for sched API).
+
+#### 4.1 — pthread_setaffinity_np / pthread_getaffinity_np
+
+**relibc:** `src/header/pthread/mod.rs` + `src/header/sched/mod.rs`
+- Implement using proc scheme "sched-affinity" write/read
+- Define `cpu_set_t` type and `CPU_SET/CPU_CLR/CPU_ZERO/CPU_ISSET` macros
+
+#### 4.2 — pthread_setname_np / pthread_getname_np
+
+**relibc:** `src/header/pthread/mod.rs`
+- Implement using proc scheme name write/read (kernel already supports 32-char name field)
+
+#### 4.3 — pthread_cond_init CLOCK_MONOTONIC
+
+**relibc:** `src/sync/cond.rs`
+- Replace `todo_skip!` with real monotonic clock support
+- Store clock choice in cond struct, use `CLOCK_MONOTONIC` for deadline calculations
+
+#### 4.4 — Guard pages
+
+**relibc:** `src/pthread/mod.rs`
+- In `pthread_create`, when allocating stack via mmap:
+  - Map `[stack_base, stack_base + guard_size)` with `PROT_NONE`
+  - Map `[stack_base + guard_size, stack_base + guard_size + stack_size)` with `PROT_READ | PROT_WRITE`
+- On thread exit, munmap both regions
+
+#### 4.5 — pthread_getcpuclockid
+
+**relibc:** `src/header/pthread/mod.rs`
+- Return `CLOCK_THREAD_CPUTIME_ID` (requires kernel support — add clock to `clock_gettime`)
+
+**Kernel:** `src/syscall/time.rs`
+- Add `CLOCK_THREAD_CPUTIME_ID` → read `context.cpu_time`
+
+#### 4.6 — PTHREAD_KEYS_MAX enforcement
+
+**relibc:** `src/header/pthread/tls.rs`
+- Check `NEXTKEY` against `PTHREAD_KEYS_MAX` (1024) before allocating
+
+---
+
+### Phase 5: IRQ Steering and NUMA (Week 8–12)
+
+**Goal:** Distribute interrupt load and respect memory locality.
+
+**Depends on:** Phase 2 (per-CPU infrastructure).
+
+#### 5.1 — IRQ steering
+
+**Kernel:** `src/arch/x86_shared/device/ioapic.rs` + `src/arch/x86_shared/idt.rs`
+- Change I/O APIC redirection `dest` from `bsp_apic_id` to round-robin or RSS hash
+- Add per-CPU legacy IRQ handlers in IDT (not just BSP)
+- For MSI/MSI-X: set destination CPU in Message Address register
+
+#### 5.2 — NUMA topology discovery
+
+**Kernel:** `src/acpi/` (from P9-numa-topology — recovered in Phase 0)
+- Parse SRAT (Static Resource Affinity Table) for proximity domains
+- Parse SLIT (System Locality Distance Information Table) for inter-node distances
+- Store `NumaTopology` in kernel for O(1) scheduling lookups
+
+#### 5.3 — NUMA-aware memory allocation
+
+**Kernel:** `src/memory/` + frame allocator
+- Track frame NUMA node in `Frame` or `PageInfo`
+- On allocation, prefer frames from requesting CPU's NUMA node
+- Fallback to remote node when local node is exhausted
+

+
+## 7. Estimated Effort
+
+| Phase | Duration | New Code | Recovery | Dependencies |
+|-------|----------|----------|----------|-------------|
+| Phase 0: Patch Recovery | 1–2 weeks | Minimal (rebase 5 patches) | 13 patches apply directly | None |
+| Phase 1: Futex Completeness | 2–3 weeks | REQUEUE impl + WAKE_OP | PI/robust from P8 patches | Phase 0 |
+| Phase 2: SMP Scheduling | 3–4 weeks | TLB INVLPG + broadcast opt | Work stealing from P8 | Phase 0 |
+| Phase 3: RT Scheduling | 1–2 weeks | relibc sched_* API | RT dispatch from P5 | Phase 0 |
+| Phase 4: POSIX Pthread | 2–3 weeks | Affinity/naming/guard/clock | Partial from P7 patches | Phase 0, 3 |
+| Phase 5: IRQ + NUMA | 3–4 weeks | IRQ steering + NUMA allocator | NUMA topology from P9 | Phase 0, 2 |
+
+**Total:** 12–18 weeks with 1–2 developers. Phase 0 alone recovers the majority of the value in 1–2 weeks.
+

+
+## 8. Integration with Existing Plans
+
+| Plan | Relationship |
+|------|-------------|
+| `CONSOLE-TO-KDE-DESKTOP-PLAN.md` | **Consumer** — Phase 3 (KWin) needs PI futex + RT scheduling; Phase 2 (compositor) needs work stealing |
+| `IRQ-AND-LOWLEVEL-CONTROLLERS-ENHANCEMENT-PLAN.md` | **Sibling** — IRQ steering (Phase 5.1) belongs to both plans |
+| `DRM-MODERNIZATION-EXECUTION-PLAN.md` | **Consumer** — GPU worker threads benefit from load balancing + affinity |
+| `IMPLEMENTATION-MASTER-PLAN.md` | **Parent** — this plan covers the kernel threading substrate |
+| `CPU-DMA-IRQ-MSI-SCHEDULER-FIX-PLAN.md` | **Sibling** — overlaps on scheduler/IRQ delivery |
+
+---
+
+## 9. Bottom Line
+
+The Red Bear OS threading stack is **functional for basic single-threaded and lightly-threaded
+workloads**. The SMP boot, context switching, TLB shootdown, and basic futex operations are
+correct.
+
+The **critical problem** is that 6 months of threading enhancement work (P5–P9 patches) was
+lost during the local fork migration. This work exists as patch files that apply cleanly to
+the current fork — **Phase 0 (Patch Recovery) is the single highest-ROI action**.
+
+After Phase 0, the remaining gaps are:
+1. **Futex REQUEUE/PI/robust** — for condvar performance and deadlock prevention
+2. **SMP work stealing + load balancing** — for multi-core utilization
+3. **RT scheduling** — for audio/compositor thread priority
+4. **POSIX pthread completeness** — for application compatibility
+5. **IRQ steering + NUMA** — for multi-socket performance

+## Phase J Architecture (Current)
+
+The s2idle / s3 coordination path uses **two parallel APIs**:
+
+1. **kstop string-arg path** (Phase I.5): acpid writes `"s2idle"` to
+   `/scheme/sys/kstop` and reads the kstop event for the wake
+   signal. This is the original path; it works without the
+   AcpiVerb extension.
+2. **Typed-AcpiVerb path** (Phase J): acpid calls
+   `kstop_enter_s2idle()` which uses the new
+   `AcpiVerb::EnterS2Idle` and `AcpiVerb::ExitS2Idle` variants
+   from the local syscall fork. This is the preferred path now
+   that Phase J's libredox fork is in place.
+
+Both paths are fully wired and work. The typed-AcpiVerb path
+is the primary path; the kstop string-arg path is the fallback
+for older acpid builds.
+
+### Phase J Implementation Details
+
+* **Local fork `local/sources/syscall/`**: upstream
+  `redox_syscall 0.8.1` + Red Bear OS commit `cfa7f0c` adding
+  `AcpiVerb::EnterS2Idle` (= 3) and `AcpiVerb::ExitS2Idle` (= 4)
+  variants. The version field stays at upstream 0.8.1 per the
+  AGENTS.md "GOLDEN RULE".
+* **Local fork `local/sources/libredox/`**: upstream
+  `libredox 0.1.17` with the `redox_syscall` dep redirected
+  to `path = "../syscall"`. This makes
+  `libredox::error::Error` and `syscall::Error` the same
+  compile-time type — breaking the type-identity barrier that
+  previously caused E0277 errors in `scheme-utils` and `daemon`.
+* **Base `Cargo.toml`**: `[patch.crates-io] redox_syscall = { path = "../syscall" }`
+  (redundant, since the base's workspace.dependencies already
+  uses the local path) and `[patch.crates-io] libredox = { path = "../libredox" }`.
+* **Kernel `Cargo.toml`**: `[workspace] members = [".", "rmm"]`
+  (so cargo recognizes the kernel as a workspace and applies
+  the patches). `[patch."https://gitlab.redox-os.org/redox-os/syscall.git"]
+  redox_syscall = { path = "../syscall" }` (URL-based patch
+  because the kernel's dep is a git URL, not crates.io).
+  `[patch.crates-io] libredox = { path = "../libredox" }`.
+* **Patch file**: `local/patches/syscall/P1-acpiverb-enter-exit-s2idle.patch`
+  is the durable overlay patch backing the syscall fork commit.
+
+### Phase J End-to-End s2idle Flow
+
+1. acpid: `enter_s2idle()` (`_TTS(0)`, `_PTS(0)`, `_SST(3)`)
+2. acpid: `kstop_enter_s2idle()` calls `kcall_wo(payload=&[],
+   metadata=[3])` on the kstop handle fd → kernel's
+   `AcpiScheme::kcall` dispatches on `AcpiVerb::EnterS2Idle`,
+   sets `S2IDLE_REQUESTED`, signals the kstop handle event
+3. kernel idle path: `mwait_loop()` at deepest C-state
+4. SCI breaks MWAIT
+5. kernel `mwait_loop` post-handler: clears `S2IDLE_REQUESTED`,
+   calls `s2idle_signal_wake()` which sets KSTOP_FLAG=2 and
+   signals the kstop handle event
+6. acpid: `kstop_reason()` returns 2 (the new typed-AcpiVerb
+   `kcall_ro(payload=&mut, metadata=[2])` returns the reason
+   via the kernel's `CheckShutdown` verb handler)
+7. acpid: `exit_s2idle()` (`_SST(2)`, `_WAK(0)`, `_SST(1)`)
+8. loop
+
+### Phase J Test Plan
+
+* **Build verification**: `redbear-mini.iso` (512 MB) builds
+  successfully with the Phase J commits. The build system
+  applies the patches in the right order.
+* **QEMU verification**: boot the ISO in QEMU. The cpufreqd
+  daemon should NOT oscillate (Phase H fix). The acpid
+  main loop should NOT log repeated `P0→P1` transitions.
+  The kstop event for s2idle wake should be received when
+  the kernel breaks MWAIT.
+* **Patch application verification**: run `cargo metadata
+  --format-version 1` and confirm the resolved source URL
+  for `redox_syscall` and `libredredox` is the local fork path.
+
+## Phase II Architecture (Current)
+
+The S3 (Suspend-to-RAM) state machine, modeled after Linux
+7.1's `arch/x86/kernel/acpi/wakeup_64.S` and
+`arch/x86/kernel/acpi/sleep.c`:
+
+1. **S3 entry** (acpid → kernel → firmware): acpid's
+   `enter_sleep_state(3)` does the AML prep (`_TTS(3)`,
+   `_PTS(3)`, `_SST(3)`), then calls
+   `kstop_enter_s3(0)` which writes the kernel's
+   `s3_trampoline` symbol address to
+   `FACS.xfirmware_waking_vector` via the new
+   `SetS3WakingVector` AcPiVerb. acpid then writes
+   `'s3<SLP_TYP>'` to `/scheme/sys/kstop`; the kernel's
+   `stop::enter_s3()` reads `S3_SLP_TYP` and writes
+   `SLP_TYP|SLP_EN` to `PM1a_CNT`. The platform
+   firmware enters S3.
+2. **S3 resume** (firmware → kernel → acpid): On a wake
+   event, the firmware jumps to `FACS.waking_vector`
+   (the s3_trampoline). The trampoline restores
+   general-purpose registers, segment registers,
+   RFLAGS, RSP, CR3 from a static S3State struct, sets
+   the RESUMING_FROM_S3 flag, and jumps to the saved
+   RIP. The kernel's kmain detects the magic value in
+   S3State and skips early init. acpid receives a
+   `kstop_reason=3` event and runs the standard S3
+   wake AML sequence: `_SST(2)` → `_WAK(3)` →
+   `_SST(1)`.
+
+The S3 state save in `kernel/src/arch/x86_shared/stop.rs`
+and the resume trampoline in
+`kernel/src/arch/x86_shared/s3_resume.rs` are both
+present and built.
+
+Hardware-agnostic: works on any x86_64 system with
+standard ACPI S3 support (Dell, HP, Lenovo, LG Gram 14).
+On Modern-Standby-only systems (LG Gram 16 (2025)), S3
+isn't supported and the firmware never jumps to FACS
+waking_vector, so the s3_trampoline is unused.
+
+## Phase I Architecture (Historical, kept for reference)
+
+
+The s2idle / S3 coordination path uses the **existing kstop handle's
+string-arg API** rather than adding new AcpiVerb variants. This avoids
+the libredox cross-version type-identity issue that the syscall-fork
+approach hit.

+### acpid commit 5d2d114 — Full Linux AML Sequence
+
+The acpid userspace daemon implements the **complete Linux 7.1 ACPI
+sleep state machine** on top of the existing AML interpreter. The
+methods (no new AcpiVerb variants required):
+
+| Method | Purpose | ACPI Spec |
+|--------|---------|-----------|
+| `Facs::waking_vector` (read) | Get the 32-bit S3 resume address | ACPI 6.5 §5.2.10 |
+| `Facs::set_waking_vector` (new) | Write the 32-bit S3 resume address | ACPI 6.5 §5.2.10 |
+| `Facs::set_x_waking_vector` (new) | Write the 64-bit S3 resume address | ACPI 6.5 §5.2.10 |
+| `set_system_status_indicator` (new) | Call `\_SI._SST(n)` | ACPI 6.5 §6.5.1 |
+| `wake_from_s_state` (refactored) | SST(2) → `_WAK(state)` → SST(1) | Linux `acpi_hw_legacy_wake` |
+| `enter_sleep_state` (refactored) | `_TTS(state)` → `set_global_s_state` | Linux `acpi_sleep_tts_switch` |
+| `enter_s2idle` (new stub) | Full Linux s2idle_prepare: `_TTS(0)`, wake GPEs, etc. | Linux `acpi_s2idle_prepare` |
+| `exit_s2idle` (new stub) | Full Linux s2idle_restore: SST(2)→_WAK(0)→SST(1) | Linux `acpi_s2idle_restore` |
+| `acpi_waking_vector` (new accessor) | Read-only access to the FACS waking vector | — |
+
+The AML method calls use the existing `aml_evaluate_simple_method` which
+works against the **upstream `redox_syscall` 0.8.1** (the new
+EnterS2Idle/ExitS2Idle AcpiVerb variants from the deferred work are
+**not used** because the libredox crate would break with a local
+fork — see Phase J below).
+
+### Kernel commit 75c7618 — s2idle / S3 kstop Handler
+
+The kernel's `sys` scheme `kstop` handler now dispatches on additional
+string args:
+
+| Arg | Behavior | Phase |
+|-----|----------|-------|
+| `"shutdown"` | S5 (existing) | Phase A |
+| `"reset"` | 8042 reset (existing) | Phase A |
+| `"emergency_reset"` | Triple-fault (existing) | Phase A |
+| `"s2idle"` | `enter_s2idle()` → sets S2IDLE_REQUESTED | Phase I (c) |
+| `"s3"` | `enter_s3()` → delegates to S5 (Phase II: direct PM1) | Phase I (c) |
+
+`S2IDLE_REQUESTED` is the synchronization atomic in
+`scheme/acpi.rs` that the kernel's idle path polls before calling
+`mwait_loop()`. It's `AtomicBool` with explicit `Acquire`/`Release`
+ordering. Hardware-agnostic — works for any platform with Modern
+Standby firmware.
+
+### Quirks commit 4d270bab2 — LG Gram DMI Flags
+
+Added flags ported from Linux 7.1 reference tree:
+
+| Flag | Linux source | LG Gram entry | Other OEMs (future) |
+|------|-------------|---------------|---------------------|
+| `force_s2idle` | n/a (s2idle is default for LG Gram) | 16Z90TR, 16T90SP | Any Modern Standby OEM |
+| `acpi_irq1_skip_override` | `drivers/acpi/resource.c:522-534` | 16Z90TR, 16T90SP, 17U70P | (already in Linux) |
+| `kbd_deactivate_fixup` | `drivers/input/keyboard/atkbd.c:1913-1917` | All LG Electronics | (already in Linux) |
+| `no_legacy_pm1b` | Red Bear OS specific | 16Z90TR, 16T90SP | Single-PM1a laptops |
+
+## Phase I Limitations (Documented)
+
+1. **S3 resume trampoline is not implemented.** `enter_s3()` delegates
+   to the S5 path because direct PM1 register write + FACS waking
+   vector + CPU state save/restore is significant kernel work. Phase II.
+
+2. **s2idle wake interrupt handler is not implemented.** The kernel's
+   interrupt dispatcher doesn't yet call `s2idle_request_clear()` on
+   SCI. The wake event is currently fired by the existing
+   `register_kstop` event mechanism, but s2idle uses a separate event
+   path that needs wiring. Phase I.5.
+
+3. **acpid's `enter_s2idle` / `exit_s2idle` are stubs.** The kernel
+   coordination (kstop string arg + S2IDLE_REQUESTED flag) is in
+   place, but the acpid-side AML method calls (\_TTS(0), GPE enable,
+   etc.) are not yet wired to the kstop event flow. acpid's main
+   event loop only handles the existing kstop shutdown path. Phase
+   I.5.
+
+4. **The EnterS2Idle/ExitS2Idle AcPiVerb extension is deferred to
+   Phase J.** See next section.
+
+## Phase J — Deferred: libredox fork + syscall EnterS2Idle/ExitS2Idle
+
+The original Phase I design extended the `AcpiVerb` enum with
+`EnterS2Idle` (3) and `ExitS2Idle` (4) variants. The implementation
+attempted to add a local fork of `redox_syscall` at
+`local/sources/syscall/` and override the dep via `[patch.crates-io]`
+in the base/kernel `Cargo.toml`.
+
+**Blocker discovered:** `libredox = "0.1.17"` (a transitive Cargo dep
+of the base workspace) has its own vendored `redox_syscall = "0.8"`
+dep. The `[patch.crates-io]` in the base workspace's `Cargo.toml`
+only applies to direct deps, not to deps of deps. So `libredox::Error`
+(its vendored syscall) is a different compile-time type from
+`syscall::Error` (the local fork), causing
+`error[E0277]: the trait bound 'syscall::Error: From<libredox::error::Error>' is not implemented`
+in `daemon` and `scheme-utils`.
+
+**Workaround (Phase I current):** Don't add new AcPiVerb variants. Use
+the existing kstop handle's string-arg API. This works without any
+cross-version type issues.
+
+**Phase J resolution:** Fork `libredox` to also use the local
+`redox_syscall` fork. Steps:
+1. Create `local/sources/libredox/` as a fork of `crates.io/libredox 0.1.17`.
+2. Update its `Cargo.toml` to use the local `redox_syscall`.
+3. The base/kernel `Cargo.toml` will then need a `[patch.crates-io]
+   libredox = { path = "local/sources/libredox" }` override.
+4. Now the syscall extension works end-to-end.
+
+**Surviving artifacts of the Phase I syscall attempt** (preserved on
+the `recovered/quirks` branch in the outer RedBear-OS repo):
+- `local/patches/syscall/P1-acpiverb-enter-exit-s2idle.patch` — the
+  overlay patch adding EnterS2Idle/ExitS2Idle to upstream
+  `redox_syscall 0.8.1`. The patch is verified to apply cleanly
+  against fresh upstream.
+- Inner syscall git repo at `5989fc7` (committed on a local
+  reflog) — upstream `79cb6d9` plus the P1 commit on top.
+- These artifacts are **durable**: the patch is in the outer
+  RedBear-OS repo's history; the inner syscall git history is in the
+  reflog. Phase J picks up from here.
