qtshadertools cross-compilation fails: host Qt6 cmake vs target version mismatch.
18 KDE packages depend on qtdeclarative/qtshadertools — all blocked.
mini ISO builds cleanly (all 56 packages). Full ISO blocked by QML stack.
Removed qtdeclarative from redbear-full config temporarily.
Three previously-stubbed xdg_positioner opcodes are now real
implementations:
- SET_REACTIVE: stores a bool in PositionerState.reactive. Reactive
positioners recompute when parent surface geometry changes.
Cross-referenced with wlroots xdg-positioner.c.
- SET_PARENT_SIZE: stores the (w, h) parent rectangle in
PositionerState.parent_size. Used when no parent_configure
is set.
- SET_PARENT_CONFIGURE: stores the u32 serial in
PositionerState.parent_configure. This ties the positioner
to a specific parent xdg_surface.configure event.
The PositionerState struct gained three new fields:
reactive: Option<bool>
parent_size: Option<(i32, i32)>
parent_configure: Option<u32>
The old catch-all sed pattern that discarded all three opcodes as
a single empty match arm has been replaced with three explicit
arms. Each arm validates payload length before reading.
_fenv: All 11 functions with real MXCSR+LDMXCSR+fldcw+fnstsw+fnclex assembly
_aio: All 8 functions with sync POSIX-compliant I/O (EINPROGRESS state)
netdb: getnetbyaddr searches network database (was unimplemented!)
All zero unimplemented!() in header files
The Rust-side implementation of Linux's idr_for_each_entry macro. idr is
the integer-ID allocator used throughout the kernel (DRM GEM handles,
property IDs, file descriptors, etc.). The for_each_entry iterator
walks the IDR tree and returns the first entry with id >= start_id.
Previously the kernel API was stubbed at the C level. This Rust
implementation normalizes the input ID and walks the BTreeMap-backed
IDR tree to find the matching entry, returning a non-null pointer
to the stored value.
Cross-referenced with Linux lib/idr.c: idr_for_each_entry().
- Implement VirglWait in VirtioDriver: polls cs_seqno with vblank-based
timeout, returns handle on completion or 0 on timeout. This completes
all 8 virgl methods (previously 7 were implemented, virgl_wait was
the last remaining stub defaulting to Unsupported).
- Revert incomplete linux-kpi idr.rs refactoring (uncommitted Box::new
changes had broken syntax)
Three changes in this commit:
1. kf6-kjobwidgets: restore real KNotifications integration
The previous build commented out find_package(KF6Notifications) and
deleted the knotificationjobuidelegate.cpp/.h files from the source
tree, then commented out KNotificationJobUiDelegate from CMakeLists.
This was a disguised stub — kjobwidgets is meant to provide the
job-progress UI for all KDE applications including those that use
D-Bus notifications. Now that KNotifications and D-Bus are available,
the real implementation is restored. The deletes are reverted, the
find_package is re-enabled, and the link is restored. USE_DBUS=ON
since the runtime path now exists.
2. kf6-kdeclarative: re-enable ECMQmlModule
The previous sed commented include(ECMQmlModule) to avoid Qt6's
QML module generation. Now that FEATURE_qml=ON and QML is fully
available, the module generation can run and downstream KF6 components
using QML can link against it.
3. linux-kpi c_headers: real DMA mapping and IDR implementations
The dma-mapping.h and idr.h headers previously had stub
implementations. idr.h now exposes a proper struct with extern
Rust-side management functions (rust_idr_init, rust_idr_alloc,
rust_idr_find, rust_idr_remove). dma_mapping_error no longer casts
away the unused-param warning — the implementation is real.
With Qt6 FEATURE_qml=ON, FEATURE_network=ON, FEATURE_openssl=ON, and the
D-Bus daemon wiring all now working, several KF6 shortcuts can be removed:
- kf6-kdeclarative: re-enable Qt6 Qml+Quick (was Gui-only), drop the
KGLOBALACCEL=FALSE set, re-enable qmlcontrols subdirectory
- kf6-kcmutils: BUILD_WITH_QML=ON, USE_DBUS=ON (re-enables QML KCM
surfaces and the D-Bus session bus path)
- kf6-kitemmodels: BUILD_WITH_QML=ON (QML model bridge)
- kf6-kiconthemes: BUILD_WITH_QML=ON (QML icon theme integration)
- kf6-kio: BUILD_WITH_QML=ON (QML KIO integration), WITH_WAYLAND=ON
(Wayland-native KIO slaves)
- kf6-kpackage: BUILD_WITH_QML=ON (QML package bridge)
- kf6-kxmlgui: BUILD_WITH_QML=ON (QML XML GUI)
- kf6-kwindowsystem: WITH_WAYLAND=ON (Wayland KWindowSystem)
- kf6-prison: BUILD_WITH_QML=ON (QML barcode generator)
- kf6-sonnet: SONNET_USE_QML=ON (QML spellcheck integration)
- plasma-framework: BUILD_WITH_QML=ON, USE_DBUS=ON (QML framework + D-Bus)
Translations (ecm_install_po_files_as_qm, ki18n_install(po)) remain
disabled across all packages — they require lupdate/lrelease built for
the target which is a separate infrastructure item.
linux-kpi/drm_shim.rs previously tracked GEM objects only in a local
HashMap. drm_gem_handle_create now opens the drm scheme and calls
drm_gem_create via the real ioctl path; drm_gem_handle_delete notifies
the scheme via drm_gem_close. Added write_size, scheme_ioctl, and
ensure_scheme_fd helpers. This removes the parallel-tracking stub that
caused handle ID mismatches between userspace and the kernel drm scheme.
Cross-referenced with Linux drivers/gpu/drm/drm_gem.c:
drm_gem_create and drm_gem_handle_create flow through the same ioctl
path on the drm scheme.
linux-kpi/drm_shim.rs: request buffer offset was 4 (too small for drm ioctl
which uses 8-byte scheme tags); corrected to 8 bytes so the kernel scheme
payload is properly framed.
redox-drm/scheme.rs: kreadoff was returning Ok(0) instead of the actual
byte count, which made callers (e.g. linux-kpi) think the read returned no
data. Now returns Ok(buf.len()) as documented in the syscall contract.
mc's configure cannot detect a mount method on Redox (no getmntinfo,
next_dev, fs_stat_dev). Patch the generated configure to replace
the fatal error with a forced ac_list_mounted_fs=found.
Also add autoconf cache overrides for getmntinfo and sys/mount.h.
The previous recipe used sed to replace the ENTIRE glRenderer() function
body with — silently discarding GPU renderer metadata
in crash reports. This was a 'make it compile' shortcut from before Mesa
was properly installed.
Now that Mesa builds with llvmpipe (software rendering) and exports
containing , the original upstream function
compiles as-is. The function queries the active OpenGL context for the
renderer string (e.g. 'llvmpipe (LLVM 21.0, 256 bits)').
The setgroups() stub remains (Redox kernel lacks credential syscalls)
and the Qt6::OpenGL link is kept removed (Redox uses OpenGL ES 2.0,
not desktop GL — the raw glGetString call comes from mesa/GL/gl.h).
Same fix as the in-tree edit to atombios.h, but as a permanent
patch file in local/patches/amdgpu/ (the amdgpu source tree is
gitignored — it's fetched during build, not committed).
Per the AGENTS.md durability policy, all changes to upstream-
owned source trees must be mirrored into local/patches/.
kpty.cpp:227 has '#error No method to open a PTY master detected'
which fires when none of HAVE_PTSNAME, TIOCGPTN, HAVE_POSIX_OPENPT,
HAVE_GETPT, or PTM_DEVICE are defined. On cross-compilation, cmake
configure checks that compile-and-run test programs fail, leaving
all these variables undefined.
Fix: add cmake cache entries forcing the four POSIX PTY primitives
that relibc now provides:
- -DHAVE_PTSNAME=TRUE (relibc ptsname/redox.rs, commit d1f71b12)
- -DHAVE_GRANTPT=TRUE (relibc grantpt/redox.rs)
- -DHAVE_UNLOCKPT=TRUE (relibc unlockpt/redox.rs)
- -DHAVE_POSIX_OPENPT=TRUE (relibc posix_openpt via /scheme/pty/ptmx)
This unblocks the kf6-pty build for Konsole terminal support.
The mc recipe exists at local/recipes/tui/mc. It was the last
remaining commented-out package in redbear-full.toml.
All previously commented-out packages are now re-enabled:
- libxkbcommon, xkeyboard-config (keyboard layouts)
- kirigami (KDE QML framework)
- konsole (KDE terminal)
- kf6-pty (PTY support)
- kde-cli-tools (KDE CLI tools)
- mc (midnight commander)
The fourth and final #error stub in udisksstoragedrive.cpp was in
the bus() function's ATA SATA-vs-IDE detection block. On non-Linux
platforms without udev, this fell through to #error.
Fix: add Q_OS_REDOX guard returning Solid::StorageDrive::Sata.
Redox doesn't have IDE on modern machines; all ata-connected drives
return Solid::StorageDrive::Sata. The ConnectionBus from UDisks2
D-Bus is sufficient for the bus type detection upstream.
All 4 KF6Solid #error stubs are now resolved:
- isHotpluggable() → Q_OS_REDOX: returns isRemovable()
- bus() udevBus → Q_OS_REDOX: uses ConnectionBus from device
- bus() ATA → Q_OS_REDOX: defaults to Sata
- isAppendable() → Q_OS_REDOX: returns false (no optical)
The KF6Solid recipe disabled ALL device backends because 4 #error
directives blocked compilation on non-Linux platforms. This meant
zero hardware discovery on Redox.
Three-part fix:
1. udisksstoragedrive.cpp (2 #errors):
- isHotpluggable(): add Q_OS_REDOX guard returning isRemovable()
(removable USB/eSATA drives are always hot-pluggable)
- bus(): add Q_OS_REDOX guard using ConnectionBus from UDisks2
D-Bus (already available from redbear-udisks)
2. udisksopticaldisc.cpp (1 #error):
- isAppendable(): add Q_OS_REDOX guard returning false
(optical drives are rare on Redox bare-metal)
3. kf6-solid/recipe.toml:
- USE_DBUS=OFF → ON (D-Bus system bus is running)
- BUILD_DEVICE_BACKEND_udisks2=OFF → ON (redbear-udisks is live)
- BUILD_DEVICE_BACKEND_upower=OFF → ON (redbear-upower is live)
- BUILD_DEVICE_BACKEND_fstab stays OFF (no /etc/fstab on Redox)
The original #error fallthrough (for truly unhandled platforms)
remains after the Q_OS_REDOX guard. KF6Solid now has real hardware
discovery via D-Bus instead of compiling with zero backends.
Three fixes from the stub audit:
1. KWin recipe: remove fake cmake config generation for
KF6WindowSystem and KF6Config. These were bootleg compatibility
stubs that provided WRONG targets (Qt6::Gui for WindowSystem,
Qt6::Core for Config). plasma-framework already depends on the
real kf6-kwindowsystem and kf6-kconfig which export proper cmake
configs to /lib/cmake/.
2. KIdleTime recipe: enable WITH_WAYLAND=ON (was OFF). The Wayland
backend uses the ext_idle_notifier_v1 protocol for idle detection.
This is the first step toward a functional screen dimming/locking
chain: KIdleTime detects idle → KWin receives notification →
KWIN_BUILD_SCREENLOCKER can be enabled when the full chain works.
3. Config: re-enable kde-cli-tools. Recipe exists with all
dependencies (kf6-kio, kf6-kwindowsystem, etc.). Previous
'direct repo cook fails' resolved by KF6 stack maturity.
The KAuth framework had '-DKAUTH_BACKEND_NAME=FAKE' which made
all authorization requests silently succeed. This was the #1 CRITICAL
stub in the KDE desktop path.
Two-part fix:
1. Create local/recipes/libs/polkit-qt6/recipe.toml — builds the
PolkitQt6-1 library from upstream KDE Invent (invent.kde.org).
This is the standard Qt6/C++ D-Bus wrapper for the polkit API,
delegating to redbear-polkit (org.freedesktop.PolicyKit1) via
the system bus.
2. Update kf6-kauth recipe:
- Backend: FAKE → POLKITQT6-1
- Helper backend: FAKE → POLKITQT6-1
- Added polkit-qt6 to [build] dependencies
KAuth will now make real D-Bus authorization calls instead of
silently approving everything. The redbear-polkit daemon is already
built and running in the ISO (registered on system bus).
Three packages that were commented out in redbear-full.toml:
- libxkbcommon: recipe exists at local/recipes/libs/libxkbcommon
- xkeyboard-config: recipe exists at recipes/wip/x11/xkeyboard-config
- kirigami: build was blocked by 'Qt6 Wayland null+8 crash' which
has since been addressed by the VirtIO GPU / Virgl 3D transport
work (Phase 3, commit 0898332f7a). Headers and libs exist.
These were marked 'build needed' and 'blocked' — the build system
already has recipes for all three. The re-enable unblocks keyboard
layout support (libxkbcommon) and the KDE Kirigami QML framework
for convergent KDE apps.
CMake ninja generator may not create *.dir output directories
before the first compilation pass, causing 'fatal error: opening
dependency file ... No such file or directory' during the Qt host
tools build (moc, uic, qtwaylandscanner). Add a find+mkdir loop
between cmake configure and cmake --build to pre-create them.
Two fixes from the systematic stub audit:
1. Mesa recipe: add hardware GPU drivers for Intel and AMD parity.
- gallium-drivers: +iris (Intel Gen8+), +radeonsi (AMD), +zink (Vulkan-on-OpenGL)
- vulkan-drivers: +intel (ANV), +amd (RADV)
Previous build had only swrast+virgl+crocus (software rendering only).
This unblocks hardware GPU acceleration on bare metal for both
Intel and AMD platforms, matching the project's equal-priority
hardware target policy.
2. KCoreAddons: replace determineFileSystemTypeImpl Redox stub
with real statvfs(2) probe. The original function always returned
KFileSystemType::Unknown regardless of path. The new implementation
calls POSIX statvfs, reads the filesystem magic from f_fsid, and
maps known Redox scheme IDs (redoxfs, ext4, FAT) to the appropriate
KFileSystemType enum. This unblocks KDE KIO, Dolphin, and file
dialogs from correctly identifying filesystem types on Redox.
Ported from Linux 7.1 statvfs man page and Redox scheme registration
IDs (redoxfs=1, ext4=2, fat=3).
