Robert Allan JamesandClaude Sonnet 5 7df2e1bae3 FABRIC.md: item 4.5d -- fortification and putc/getc fixed, PM Timer stall now blocks
Finding 2 (putc/getc) fixed via shim.c backfill (previous commit). With
both Finding 1 (-U_FORTIFY_SOURCE) and Finding 2 fixed, amd64 links clean
at -O2 -- rigorously confirmed zero new warnings by diffing normalized
warning text between -O0 and -O2 builds (empty diff, ~3040 pre-existing
warnings in vendored code unchanged).

New Finding 3, not fixed, now blocking: amd64 boot stalls for minutes
inside calibrate_tsc_with_pmtimer() (timer.c:560-589) at -O2 -- a
mainline busy-wait loop reading the ACPI PM Timer via genuinely-volatile
inl() until 1000 real ticks elapse, bounded by a 5M-iteration timeout. A
one-shot diagnostic probe (reverted after capture) caught exactly one
checkpoint in 55 seconds of observation, then nothing -- not yet
root-caused whether this is the 5M-iteration timeout itself taking several
minutes to exhaust under -O2, or a genuine non-terminating condition.

Makefile.starkernel reverted to -O0 again; nothing broken landed in
history. Routine artifacts from this session's boot attempts included.

logs/

QEMU acceptance-run history and Tripod smoke-test results.

  • <timestamp>/{amd64,aarch64,riscv64}/ — 255 timestamped three-arch QEMU acceptance run directories, one per invocation of the kernel QEMU acceptance workflow.
  • qemu-screenshot-*.png, qemu-screenshot-*.log, qemu-{amd64,aarch64,riscv64}-*.log, fbtest-console-*.png — loose timestamped QEMU serial captures and framebuffer screenshots from individual manual runs (not part of the timestamped-directory convention above).
  • hermes-tripod-smoke-results.md, hermes-channel-smoke-results.md — captured output from tools/hermes_tripod_smoke.sh and tools/hermes_channel_smoke.sh.
  • hermes-tripod-integration-design.md — design notes for the Tripod integration test.

Note: QEMU_BASELINE.log at the repo root (not in this directory) is the primary kernel regression baseline referenced by .claude/CLAUDE.md; the logs here are supplementary historical captures. See also logs2/ (a separate, flatter QEMU log archive) and experiments/bare_metal/runs/ (DoE-specific run output).
