Gnulib generates lib/sched.h which wraps the system sched.h via
#include_next, but the #if @HAVE_SCHED_H@ guard evaluates to 0 during
cross-compilation, preventing sched_param typedef from being visible.
Adding ac_cv_header_sched_h=yes fixes the guard.
fstools.mk: Use canonical local/sources/ paths for installer and redoxfs
cargo install --path. The recipes/ symlink chain caused cargo to resolve
path dependencies (../libredox, ../redoxfs, ../syscall) relative to the
recipe directory instead of the canonical source location, breaking
the host build.
bison: Add cross-compilation cache variables for POSIX spawn support.
Gnulib's configure couldn't detect the system spawn.h during cross-compile,
causing generated lib/spawn.h to omit #include_next, leaving
POSIX_SPAWN_* constants undefined.
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.
Previously: host_redox_stubs returned ENOSYS for all syscalls except
close/munmap/get_euid/ruid/egid/rgid — silent failures when IOMMU
code was tested on the host.
Now (host only):
- open/read/write/close → real libc file I/O
- mmap → real libc memory allocation (MAP_ANON|MAP_PRIVATE)
- munmap → real libc munmap
- clock_gettime → real libc CLOCK_REALTIME
- fstat → real libc fstat
- fsync/fdatasync/ftruncate → real libc ops
- getpid/getuid/geteuid/getgid/getegid → real libc
- strerror → real libc strerror (not hardcoded message)
- 12 remaining unsupported ops: ENOSYS with same semantics
(dup, signals, waitpid, namespaces — not needed for IOMMU tests)
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.
