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.
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)
