vasilito 7c2ea9b5e3 amdgpu/linux-kpi: replace remaining stubs with real implementations
- Implement krealloc in linux-kpi memory.rs with GFP-aware tracker lookup,
  copying, and zeroing of grown regions; add krealloc declaration to slab.h
- Align __GFP_ZERO/__GFP_NOWARN and GFP_* values between linux-kpi/slab.h
  and redox_glue.h; make __GFP_ZERO a meaningful flag bit
- Add missing POSIX/errno base constants (EFBIG, EISDIR, ESPIPE, etc.) to
  linux-kpi linux/errno.h so firmware-size checks and other drivers compile
- Harden linux-kpi bug.h: BUG()/BUG_ON() abort, WARN_ON_ONCE only warns once,
  BUILD_BUG_ON uses _Static_assert
- Harden redox_glue.h: add PCI_COMMAND_* flags, CONFIG_HZ/HZ, jiffies
  conversion macros, once-only WARN_ON_ONCE, _Static_assert BUILD_BUG_ON
- Implement redox_pci_enable_device/redox_pci_set_master with real local state
  and command-bit updates; document pcid-spawner pre-enable
- Remove realloc-only krealloc from redox_stubs.c; it now links from linux-kpi
- Fix wait_for_completion_timeout to interpret timeout as jiffies and convert
  to milliseconds, and update msecs/usecs_to_jiffies to use HZ
- Stage previously completed firmware-loader path deps and constructor fix
- Stage base and relibc submodule pointer updates from prior work

vasilito 8ba00f2880 firmware-loader: use path dependencies for redox forks
Replace version-string deps on redox_syscall, redox-scheme, and
libredox with path dependencies pointing to local/sources/ forks.
This aligns with local/AGENTS.md local-fork-dependency rule and
eliminates the crates.io vs local fork ambiguity that causes
mismatched-type link errors.

vasilito 5acd4b4c23 firmware-loader: premium upgrade — BuiltinRegistry, LoadStats, builder API
- BuiltinFirmware + BuiltinRegistry: compile-time embedded firmware
  (Linux 7.1 firmware_request_builtin_buf pattern)
- LoadStats: hits/misses/timeouts/cache_hits/latency tracking
  (Linux 7.1 fw_cache stats pattern)
- Builder API: with_builtins(), with_retry(), with_max_bytes()
- stats() accessor for runtime monitoring
- All new fields initialized in with_components constructor

vasilito 836e6d2645 iommu: fix unsafe-as-cast syntax in host stubs (Rust 2024 edition)
Parenthesize  because Rust 2024 edition does
not allow bare  — it requires .
Affected geteuid/getuid/getegid/getgid host stubs.

vasilito 33107cb323 firmware-loader: refactor CacheMetadata/FirmwareFallback to use named constructors
Replace ad-hoc struct literals scattered across the source with
named constructor methods (CacheMetadata::placeholder, CacheMetadata::from_source,
FirmwareFallback::load_defaults, FirmwareFallback::load_from_dir,
FirmwareFallback::builtins). This is not a behavior change — it's a
readability fix that makes the field semantics explicit.

Why this matters:
- Previously every struct literal had to remember the full set of
  fields including the cache/stats/retry tunables. Adding a new field
  required finding every literal in the source tree.
- With named constructors, new fields only need to be set once in
  the canonical builder. Test/placeholder sites stay minimal.
- Type-checked signatures at call sites: a placeholder takes (key, len),
  a from_source takes (requested_key, source_key, signature). The
  compiler now verifies you pass a SourceSignature when you need one.

Cross-referenced with Linux drivers/base/firmware_loader.c: the
underlying semantics (placeholder for in-progress loads, persistent
cache for loaded blobs, builtin fallbacks for known drivers) are
preserved.

vasilito e00f0d7817 firmware-loader: premium upgrade — builtins, stats, retry, limits (Linux 7.1 port)
Additions cross-referenced with Linux 7.1 drivers/base/firmware_loader/:

- BuiltinFirmware + BuiltinRegistry: compile-time embedded firmware
  (main.c:755-768 firmware_request_builtin_buf())
- LoadStats: hits/misses/timeouts/cache_hits/latency tracking
  (fw_cache stats pattern)
- Retry with exponential backoff: configurable retries+delay
  (_request_firmware() retry loop)
- Configurable max firmware bytes (default 256MB)
- SHA-512 verification toggle
- Removed unnecessary #[allow(dead_code)] on used public API

FirmwareRegistry now supports: builtins, stats, retry, size limits,
sha512 verify — all gated behind builder-pattern with_* methods.

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.

vasilito 550551d8bc fix: migrate all local recipe Cargo.toml deps from local/sources/ to recipes/core/base/ symlinks
Systemic fix: all local recipes (~150 references across 40+ Cargo.toml files)
now resolve libredox, redox_syscall, and redox-scheme through
recipes/core/base/ symlinks instead of local/sources/ paths.
Eliminates lockfile collision between Cargo's resolution of the same
package through different path strings (local/sources/ vs recipes/core/base/).

This is required because the base recipe's workspace Cargo.toml resolves
these deps through recipes/core/base/ (via symlink chain from the
recipe copy location), and Cargo treats different path strings to the
same directory as different packages.

vasilito b8aac3c9bc D7: editor multi-cursor support
Add secondary_cursors field to Editor with insert_char_multi,
delete_back_multi, delete_forward_multi methods. Right-to-left
processing ensures position shifts don't corrupt earlier insertions.

7 new tests: add/clear, all_positions, insert, delete_back,
delete_forward, unicode, duplicate-add.

vasilito a140014226 feat: recipe durability guard — prevents build system from deleting local recipes
Add guard-recipes.sh with four modes:
- --verify: check all local/recipes have correct symlinks into recipes/
- --fix: repair broken symlinks (run before builds)
- --save-all: snapshot all recipe.toml into local/recipes/
- --restore: recreate all symlinks from local/recipes/ (run after sync-upstream)

Wired into apply-patches.sh (post-patch) and sync-upstream.sh (post-sync).
This prevents the build system from deleting recipe files during
cargo cook, make distclean, or upstream source refresh.

vasilito f5e760ea39 Desktop Phase 1: add 77 tests to evdevd, udev-shim, firmware-loader
Phase 1 desktop substrate test coverage for the three runtime services
that must be runtime-trusted before compositor work begins:

- evdevd device.rs: 44 tests (input device constructors, capability
  bitmaps, key/led state tracking, abs_info defaults/overrides,
  bitmap_from_codes edge cases)
- udev-shim device_db.rs: 13 tests (DeviceInfo construction, subsystem
  naming, id_path formatting, input kind detection, property formatting
  for GPU/keyboard/mouse, device_info/uevent output, PCI fallback)
- firmware-loader scheme.rs: 20 tests (openat validation, read offsets,
  fstat/fsize, EROFS enforcement, mmap_prep bounds, mmap/munmap/on_close
  deferred cleanup lifecycle)

Total: 65 evdevd, 15 udev-shim, 24 firmware-loader — all passing.

vasilito 50b731f1b7 Red Bear OS — microkernel OS in Rust, based on Redox
Derivative of Redox OS (https://www.redox-os.org) adding:
- AMD GPU driver (amdgpu) via LinuxKPI compat layer
- ext4 filesystem support (ext4d scheme daemon)
- ACPI fixes for AMD bare metal (x2APIC, DMAR, IVRS, MCFG)
- Custom branding (hostname, os-release, boot identity)

Build system is full upstream Redox with RBOS overlay in local/.
Patches for kernel, base, and relibc are symlinked from local/patches/
and protected from make clean/distclean. Custom recipes live in
local/recipes/ with symlinks into the recipes/ search path.

Build:  make all CONFIG_NAME=redbear-full
Sync:   ./local/scripts/sync-upstream.sh
