LG Gram Round 4: _fenv POSIX stubs + build verification + MWAIT confirmed
Round 4 deliverables:
1. relibc _fenv POSIX functions implemented (commit e5419e44):
- 11 unimplemented!() stubs replaced with real x86 MXCSR/x87 ops
- feclearexcept through feupdateenv — full fenv.h implementation
- Constants/types corrected for x86-64 ABI compatibility
2. Build verification: base cook SUCCEEDS
- All LG Gram acpid+ps2d+lid-switch+redox-driver-sys changes
compile and link for x86_64-unknown-redox
- Relibc cook fails on cross-compile denied warnings (unused
import + unnecessary unsafe) — host cargo check passes, root
cause needs further investigation
3. Phase 9.1 MWAIT idle loop confirmed COMPLETE (parallel session):
- idle_loop() + mwait_loop() with sti;monitor;mwait inline asm
- LPIT hint integration + s2idle wake post-handler
- Updates assessment: Phase 9.1 was already done
4. Build-blocker fixes for parallel agent work:
- relibc socket.rs: missing String import (commit 3c5dc9d5)
- base dhcpd: String -> &str type mismatch (commit 24ee3bb1)
- base ixgbed: pci_allocate_interrupt_vector method->free function
(base commit f9eff050)
5. Broad stub sweep:
- 11 relibc _fenv stubs fixed this round
- Remaining ~32 relibc stubs mostly in commented-out code
- All other forks clean
Submodule pointers updated for:
relibc -> e5419e44 (_fenv + String import + unsafe-block fix)
base -> f9eff050 (ixgbed + dhcpd + common path + lid-open)
kernel -> bb4a97ec (SMBIOS + ioapic + page-fault fix)
