Extract protocol-agnostic FenceTimeline from Intel to shared
src/drivers/fence.rs — atomic-based fence tracking suitable
for Intel, VIRGL, and AMD drivers.
Extract protocol-agnostic SyncobjManager from Intel to shared
src/drivers/syncobj.rs — syncobj create/destroy/signal/reset/
wait/query and sync_file fd export/import.
Wire both into VirtioDriver:
- Add FenceTimeline + SyncobjManager fields
- Implement all 5 GpuDriver syncobj trait methods
(create, destroy, wait, export_fd, import_fd)
- Track fence seqnos in virgl_submit_3d (allocate
before submit, signal after completion)
Intel fence.rs and syncobj.rs converted to thin re-export
modules pointing at shared sources — no behavioral change
for Intel driver.
This gives Mesa VIRGL userspace the standard DRM syncobj
API for GPU/compositor synchronization.
Passes the current Unix timestamp as BUILD_TIMESTAMP env var
to cargo, so rtcd can use it as a fallback when the hardware
RTC is unavailable or returns invalid data.
bison: fix __fseterr stub injection using LIBS variable instead
of ar rcs to avoid static archive member ordering issues.
Root cause chain discovered and fixed:
1. GCC built-in stddef.h shadowed by relibc's _STDDEF_H guard
→ fix_types.h with guarded typedefs for 15+ sys types
2. gnulib configure bakes raw typedefs into GL_CFLAG_GNULIB_WARNINGS
→ strip them from Makefiles after configure
3. __fseterr/__freadahead don't exist in relibc
→ compile C stubs and inject into link via Makefile patch
The recipe pattern is documented and reusable for other gnulib packages
(ninja-build, diffutils, etc.).
Also: bootloader recipe needs RUSTFLAGS=-Zunstable-options for
custom target support after redoxer toolchain restore.
Proven recipe pattern for gnulib cross-compilation on Redox:
1. fix_types.h with guarded typedefs for ALL sys/types.h types
2. Strip raw typedefs from GL_CFLAG_GNULIB_WARNINGS after configure
3. Set cache vars for functions gnulib can't detect
Remaining: __fseterr/__freadahead stubs for linker (need relibc-level
or recipe-level .o injection)
Root cause: gnulib configure bakes raw typedef statements
(typedef long unsigned int size_t; etc.) into the generated
Makefile's GL_CFLAG_GNULIB_WARNINGS variable. These break
shell command parsing when expanded on recipe lines.
Fix:
1. Strip raw typedefs from all generated Makefiles after configure
2. Provide fix_types.h with guarded typedefs for size_t, ptrdiff_t,
off_t, wchar_t, ssize_t, time_t
3. Force-include fix_types.h via CPPFLAGS to work around the
cross-compiler's GCC built-in stddef.h ordering issue
Also: comprehensive upstream relibc comparison and import plan
The cross-compiler's GCC built-in stddef.h is blocked by relibc's
_STDDEF_H guard, causing size_t/off_t/ptrdiff_t to be undefined.
Add fix_types.h with guarded typedefs and force-include via CPPFLAGS.
Also: comprehensive upstream relibc comparison for systematic import.
Remaining: redoxer env overrides CC, injecting broken stdint typedefs
from its toolchain. This needs a redoxer-level fix to clean the
injected flags before passing to build commands.
Without this cache variable, gnulib's configure incorrectly assumes
time_t is unavailable when cross-compiling for Redox, generating
broken fallback headers that fail with 'time_t undeclared' at
the compile-time integrality check.
Red Bear OS is a full fork. All sources must be available from git clone
with zero network access. Removed gitignore rules that excluded fetched
source trees under recipes/*/source/, local/recipes/kde/*/source/,
local/recipes/qt/*/source/, and vendor source trees.
Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded.
127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt
frameworks, mesa, wayland, DRM drivers, and every other recipe source.
