vasilito e01466a6a6 state: max KDE surface reached — 40 enabled, 41 pkgar 
Hard platform limit: kirigami requires QML JIT (QQuickWindow/QQmlEngine
headers) which is disabled on Redox. kirigami blocks plasma-framework,
plasma-workspace, plasma-desktop.

Built this session:
- Qt6::Sensors v6.11.0 (520KB pkgar, dummy backend)
- libinput v1.30.2 + libevdev v1.13.2 (both pkgar in repo)
- 9 previously-commented KDE packages now enabled + building
- KWin: cmake build attempt with Sensors + libinput deps
- 42 KDE source archives all versioned (zero vunknown)

Remaining gated by QML JIT: kirigami, plasma-framework,
plasma-workspace, plasma-desktop
Remaining with source issues: breeze, kde-cli-tools, kf6-prison
Remaining empty package: kf6-knewstuff

vasilito 761e0d9de7 state: 36/48 KDE packages build, 12 blocked — honest final state 
The literal task 'build ALL KDE packages' cannot be 100% completed
because 12 packages require upstream dependencies not available on Redox:
- kirigami + plasma* (4): QML JIT disabled — no QQuickWindow/QQmlEngine
- kwin real build (1): Qt6::Sensors port needed
- breeze + kf6-kio + kf6-knewstuff + kde-cli-tools (4): source issues
- plasma extras (3): transitive blockers

What WAS completed:
- Cookbook topological sort fix (root cause — all deps now correct order)
- kf6-attica recipe (183 files, 2.4MB pkgar)
- 12 I2C/GPIO/UCSI daemons archived as durable patches
- Source archival system (make sources)
- Config + all docs synced, no contradictions

vasilito 10caab7085 boot: real Wayland compositor, Intel DRM Gen8-Gen12, kernel 4GB fix, virtio-gpu driver 
Comprehensive boot process improvement across the entire stack:

Compositor (NEW): Real Rust Wayland display server (690 lines)
- Full XDG shell protocol (15/15 protocols implemented and verified)
- wl_shm.format, xdg_wm_base, xdg_surface.get_toplevel support
- wl_buffer.release lifecycle, buffer composite to framebuffer
- Framebuffer mapping via scheme:memory (Redox) with fallback
- PID/status files for greeterd health checks
- Integration test suite (3 cases passing)
- Diagnostic tool: redbear-compositor-check

DRM/KMS Chain:
- KWIN_DRM_DEVICES=/scheme/drm/card0 wired through init→greeterd→compositor
- session-launch propagates KWIN_DRM_DEVICES (new test, 11/11 pass)
- DRM auto-detect + 5s wait loop in compositor wrapper
- Boot verified: compositor uses DRM backend in QEMU

Intel DRM:
- Gen8-Gen12 supported with firmware (SKL/KBL/CNL/ICL/GLK/RKL/DG1/TGL/ADLP/DG2/MTL/ARL/LNL/BMG)
- Gen4-Gen7 device IDs recognized, unsupported with clear error message
- Linux 7.0 i915 reference for all 200+ device IDs
- Display fixes: sticky pipe refresh, PIPE=4/PORT=6, 64-bit page flip, EDID skeleton
- 4 durability patches wired into recipe

VirtIO GPU Driver (NEW):
- 220-line DRM/KMS backend for QEMU virtio-gpu
- Full GpuDriver trait implementation (11 methods)
- PCI BAR0 framebuffer mapping, connector/mode info, GEM management

Kernel:
- 4GB RAM hang root cause: MEMORY_MAP overflow at 512 entries → fixed to 1024
- Canary chain R S 1 2 3 4 5 6 7 (9 COM1 checkpoints through boot)
- Verified: kernel boots at 4GB with all canaries present
- 3 durability patches (P0-canary, P1-memory-overflow)

Live ISO:
- Preload capped at 1 GiB with partial preload messaging
- P5 patch wired into bootloader recipe

Greeter:
- Startup progress logging (4 checkpoints)
- QML crash diagnostic (exit code 1 → specific error message)
- greeterd tests: 8/8 pass

Boot Daemons:
- dhcpd: auto-detect interface from /scheme/netcfg/ifaces/
- i2c-gpio-expanderd: I2C decode retry (3× with 50ms delay)
- ucsid: same I2C decode hardening
- Compositor: safe framebuffer fallback (prevents crash)

Qt6 Toolchain:
- -march=x86-64 for CPU compatibility (prevents invalid_opcode on core2duo)
- -fpermissive for header compatibility (unlinkat/linkat redefinition)

Documentation:
- BOOT-PROCESS-IMPROVEMENT-PLAN.md (comprehensive, 320 lines)
- PROFILE-MATRIX.md: ISO organization, RAM requirements, known issues
- BOOT-PROCESS-ASSESSMENT.md: Phase 7 kernel hang diagnosis
- Deleted 4 stale docs (BAREMETAL-LOG, ACPI-FIXES, 02-GAP-ANALYSIS, _CUB_RBPKGBUILD)
- Cross-references updated across all docs

KWin stubs replaced with real compositor delegation.
redbear-kde-session script created for post-login session launch.
30+ files, 10 patches, 3 binaries, 22 tests, 0 errors.

vasilito 752bceb3e9 Enable IPv6 foundation in relibc: inet_pton/ntop, TCP socket options, DNS AAAA 
Add three relibc patches (42 total) to close QtNetwork-critical socket gaps:
- P3-inet6-pton-ntop: AF_INET6 address parsing/formatting with RFC 5952
  shorthand, IPv4-mapped suffix support
- P3-tcp-sockopt-forward: forward IPPROTO_TCP getsockopt/setsockopt to
  scheme daemon instead of hitting todo_skip
- P3-dns-aaaa-getaddrinfo-ipv6: AAAA DNS record queries, lookup_host_v6,
  dual-stack getaddrinfo with sockaddr_in6 entries

Also fix P3-tcp-nodelay to use sys_call_wo + from_raw_parts (const) in the
SOL_SOCKET setsockopt fallback — setsockopt sends data to the kernel, not
reads from it.

vasilito 7edce33927 Code review fixes: branding consistency, exec euid check, netdb retry robustness 
- Fix login prompt: 'RedBear login:' → 'Red Bear login:' (consistent branding)
- exec-root-bypass: check both ruid and euid for root bypass (Linux checks effective UID)
- netdb-retry: remove dead variables, check send() return on retry, clarify timeout comment

vasilito 65acab85bb Split base cumulative patch and add relibc AIO stubs, KDE recipes 
Base patch extraction (8 topic-grouped patches from the 17k-line monolith):
- P2-ps2d-improvements: PS/2 controller flush/retry, mouse state machine, named producers
- P2-storage-error-handling: AHCI/IDE/NVMe/VirtIO unwrap/expect removal
- P2-usb-pm-and-drivers: suspend/resume, SCSI enablement, staged port fallback
- P2-network-error-handling: e1000/ixgbe/rtl8139/rtl8168d/virtio-net error propagation
- P2-pcid-cfg-access: PCI config I/O port and ECAM graceful fallbacks
- P2-ihdad-hda-stream: InputStream support, public stream types, Debug derives
- P2-init-acpid-wiring: acpid weak dependency on drivers/hwd/pcid-spawner
- P2-misc-daemon-fixes: audiod/usbhidd/zerod graceful degradation

relibc P3-aio.patch: synchronous POSIX AIO fallback (aio_read, aio_write,
aio_error, aio_return, aio_cancel, aio_suspend, aio_fsync, lio_listio)
for Qt6 QIODevice compatibility. 36 patches total in relibc recipe.

KDE recipes: breeze (widget style, decorations disabled), kde-cli-tools
(kioclient, kreadconfig, etc., kdesu disabled).

vasilito 530eb841db Add relibc fenv and sched POSIX implementations 
P3-fenv: x86_64 SSE/x87 inline asm for 10 FP environment functions
(feclearexcept, fegetenv, fegetexceptflag, fegetround, feholdexcept,
feraiseexcept, fesetenv, fesetexceptflag, fesetround, fetestexcept,
feupdateenv) with proper MXCSR and x87 CW register access.

P3-sched: 6 scheduler functions (sched_get_priority_max/min,
sched_getparam, sched_rr_get_interval, sched_setparam,
sched_setscheduler) with EINVAL for bad policy and no-op validation
since Redox has no real-time scheduler.

vasilito 9ddf68ce7b Add 8 relibc POSIX compatibility patches for desktop stack 2026-04-25 17:37:54 +01:00
vasilito 296861f1ce Fix mc 100% CPU hang: select() non-epoll timeout and signal.h stdint include 
relibc select_epoll() forced timeout=0 when any FD doesn't support epoll
(e.g. TTY on Redox), causing busy-loop. Poll with 100ms interval instead.

Also add stdint.h to signal/cbindgen.toml sys_includes so signalfd_siginfo
struct types (uint32_t, int32_t) resolve without build errors.

vasilito 843f30ba42 Fix relibc netdb/lookup: use-after-move and unsafe block errors 
Upstream relibc netdb DNS lookup has two bugs exposed by Rust 2024 edition
strict unsafe handling:

1. packet_data is moved into Box::via into_boxed_slice() but the retry
   loop tries to call packet_data.as_ptr() on the moved value. Use the
   already-created raw pointer packet_data_ptr instead.

2. close() is a safe function in relibc, so wrapping it in unsafe{}
   triggers unused-unsafe (promoted to error by -D unused-unsafe). Remove
   the unnecessary unsafe blocks around close() calls.

Patch carries in local/patches/relibc/P3-netdb-lookup-retry-fix.patch and
is applied via the relibc recipe patches list.

vasilito 619fd0f2d1 Fix relibc strtold linkage for C++ consumers 
Keep the relibc overlay consistent so the generated stdlib header preserves C linkage for strtold and the existing toolchain can still satisfy stale C++ callers while it is refreshed.

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
