- Bump submodule/base to the acpid AML-handler hardening (bounded stall,
mutex owner-check, static _PSS/_PSD/_CST/_CPC cache, panic-free scheme
path, observability). Proven NOT a regression: a mutex-only baseline
wedges identically under load in a 3/3 framebuffer-ground-truth test,
so the residual under-load boot wedge is head-of-line blocking in
initnsmgr, not acpid.
- Add local/docs/INITNSMGR-CONCURRENCY-DESIGN.md: the concrete
worker-offload design (Design A) that decouples the blocking openat
from the initnsmgr dispatch loop, plus Design B (kernel O_NONBLOCK +
deferred single-thread), a staged plan, and validation rules. Key
finding baked in: redox_rt's Mutex is a spinlock, so the cap_fd must be
resolved under a short lock and the openat run with the lock released.
- Update INIT-NAMESPACE-MANAGER-SCALABILITY-PLAN.md with the acpid
hardening section (done vs the still-deferred #1 transport decoupling).
- Add local/patches/wip-initnsmgr/step1-send-refactor.patch: the
compiled-but-not-yet-boot-validated Step 1 (Rc<RefCell> -> Arc<Mutex>
Send refactor) of initnsmgr, saved durably. It is intentionally NOT in
the base gitlink: bootstrap is the earliest-boot component and this
must be boot-validated on an idle host (the current host is under heavy
external load) before landing. Steps 2-5 (worker bring-up) likewise
need an idle host.
