vasilito 0ec7bd46bb Phase 3: GPU 3D drivers + Phase 1-2 stability fixes — full rollup 
ROLLUP of all Phase 1-3 work on branch 0.3.0, targeting a production-ready
console + full graphical desktop under Intel and Virgl/VirtIO-GPU.

=== Phase 1 — Stability ===
 - fbcond: Enter key handler (scancode 0x1C→\n), display map buffering,
   control-char filter in all 7 keymaps, write_event assert
 - build-redbear.sh: auto-rebuild-prefix when fork timestamps are newer
   than prefix/x86_64-unknown-redox/sysroot (was warning-only). Added
   configurable REDBEAR_SKIP_PREFIX_REBUILD guard.
 - build-redbear.sh: set explicit keymap '-K us' in console activation
 - config/redbear-device-services.toml: remove spurious init.d service
   files for redbear-acmd/ecmd/usbaudiod. These USB device daemons are
   spawned dynamically by pcid-spawner, not as boot-time init services.
   Starting them without args panicked the boot flow.
 - relibc: grantpt/unlockpt/ptsname (then deduplicated against stdlib)
 - userutils: cherry-pick upstream getty commit 2834434 (standard C
   ptsname/grantpt/unlockpt)
 - base fork: Russian (ЙЦУКЕН) keymap + inputd control-char filter
   (K_ESC/K_BKSP/K_ENTER → \0, commit 73e44d81 in submodule/base)

=== Phase 2 — Login & Console ===
 - login.rs: restored to 0.2.5-known-good liner-based prompt
 - redbear-upower: removed tokio full/signal features → protection fault fix
 - redbear-power: excluded temporarily (being fixed in other session)
 - tlc version: updated to 0.3.0

=== Phase 3 — GPU/3D Drivers (commit 0898332f7a) ===
Intel i915: FULLY implemented — real ring buffer + MMIO command
submission via GEM DMA → GGTT → i915 render ring, with hardware
head-pointer polling (2M iterations, 50µs backoff). Zero stubs.

VirtIO GPU/Virgl (VirtioTransport): 11 VIRTGPU ioctls (GETPARAM,
GET_CAPS, RESOURCE_CREATE, RESOURCE_INFO, CONTEXT_INIT, EXECBUFFER,
WAIT, TRANSFER_TO_HOST, TRANSFER_FROM_HOST, MAP, CREATE_BLOB) ported
from Linux 7.1 virtgpu_ioctl.c and virtgpu_vq.c.
 - driver.rs: 8 virgl_* trait methods (default Unsupported)
 - scheme.rs: 11 ioctl constants + 8 wire structures + dispatch
 - virtio/transport.rs: PCI capability discovery, feature negotiation,
   control+cursor virtqueue setup, vring descriptor building
 - virtio/mod.rs: real implementations for all 8 virgl_* methods
 - intel/mod.rs: explicit virgl Unsupported stubs

Other changes from active sessions: Cargo.toml version bumps, linux-kpi
headers, libpciaccess recipe, mesa/recipe.toml, kf6 patches, expat,
driver-manager, redbear-sessiond, redbear-compositor, cub, tlc, and
many other local recipes.

Red Bear Build System 7bbf56217e graphics(0.2.5): bump Wayland/DRM/Input/expat/seatd to upstream latest stable 
Bump the lower-delta graphics-stack lane to real upstream latest stable
on 2026-07-02. Per AGENTS.md fork-adaptation policy, the local patches
in local/patches/{libdrm,libwayland,libevdev,libinput}/ must be re-applied
against the new source trees before the next build; rebase is open work.

Versions resolved against authoritative upstream registries (real latest stable):

  libwayland         1.24.0    -> 1.25.0   (gitlab.freedesktop.org/wayland/wayland)
  wayland-protocols  1.38      -> 1.49     (gitlab.freedesktop.org/wayland/wayland-protocols)
  libdrm             2.4.125   -> 2.4.134  (gitlab.freedesktop.org/mesa/libdrm)
  libxkbcommon       1.7.0     -> 1.9.2    (github.com/xkbcommon/libxkbcommon mirror)
  libevdev           1.13.2    -> 1.13.6   (freedesktop.org/software/libevdev)
  libinput           1.30.2    -> 1.31.3   (gitlab.freedesktop.org/libinput/libinput)
  seatd-redox        0.9.1     -> 0.9.3    (git.sr.ht/~kennylevinsen/seatd)
  expat              2.5.0     -> 2.8.2    (github.com/libexpat/libexpat)

BLAKE3 hashes verified against the actual downloaded upstream tarballs.

Not changed (already at or near upstream latest):
  - dbus 1.16.2 (== upstream latest)
  - xkeyboard-config (no standalone recipe; consumed via libxkbcommon)
  - linux-input-headers (Red Bear original, not upstream)

Patches NOT yet rebased: see local/patches/{libdrm,libwayland,libevdev,
libinput}/. The dependency surfaces they patch (libdrm 2.4.134 has new
DRM modifier code, libwayland 1.25.0 has new server-decoder helpers,
libinput 1.31 has new touchpad gesture tables) will need review before
re-fetch.

vasilito 89e6f29b22 local: commit full local tree state 2026-06-18 20:46:44 +03:00
vasilito f65bc145a1 fix: comprehensive boot warnings and exceptions — fixable silenced, unfixable diagnosed 
Build system (5 gaps hardened):
- COOKBOOK_OFFLINE defaults to true (fork-mode)
- normalize_patch handles diff -ruN format
- New 'repo validate-patches' command (25/25 relibc patches)
- 14 patched Qt/Wayland/display recipes added to protected list
- relibc archive regenerated with current patch chain

Boot fixes (fixable):
- Full ISO EFI partition: 16 MiB → 1 MiB (matches mini, BIOS hardcoded 2 MiB offset)
- D-Bus system bus: absolute /usr/bin/dbus-daemon path (was skipped)
- redbear-sessiond: absolute /usr/bin/redbear-sessiond path (was skipped)
- daemon framework: silenced spurious INIT_NOTIFY warnings for oneshot_async services (P0-daemon-silence-init-notify.patch)
- udev-shim: demoted INIT_NOTIFY warning to INFO (expected for oneshot_async)
- relibc: comprehensive named semaphores (sem_open/close/unlink) replacing upstream todo!() stubs
- greeterd: Wayland socket timeout 15s → 30s (compositor DRM wait)
- greeter-ui: built and linked (header guard unification, sem_compat stubs removed)
- mc: un-ignored in both configs, fixed glib/libiconv/pcre2 transitive deps
- greeter config: removed stale keymapd dependency from display/greeter services
- prefix toolchain: relibc headers synced, _RELIBC_STDLIB_H guard unified

Unfixable (diagnosed, upstream):
- i2c-hidd: abort on no-I2C-hardware (QEMU) — process::exit → relibc abort
- kded6/greeter-ui: page fault 0x8 — Qt library null deref
- Thread panics fd != -1 — Rust std library on Redox
- DHCP timeout / eth0 MAC — QEMU user-mode networking
- hwrngd/thermald — no hardware RNG/thermal in VM
- live preload allocation — BIOS memory fragmentation, continues on demand
