Robert Allan JamesandClaude Sonnet 5 dd043bbfeb Artemis Milestone 2e: PORTSC connect/disconnect detection, verified live
xhci_poll_events()'s Port Status Change branch now decodes the Port ID
from the event TRB (XHCI_PSC_EVT_PORT_ID, new in xhci.h), reads that
port's PORTSC.CCS via a new xhci_port_regs() helper, and logs connect vs.
disconnect. Acknowledges by writing back only PP (preserved) and CSC (the
bit being cleared) -- PED/PR/other _C bits written 0 so nothing is
accidentally disabled, reset, or silently cleared, matching the RW1C
discipline already used for ERDP.EHB in 2d.

Verified with the real target scenario via QMP hotplug on all three
architectures: boot with the xHCI controller present but no USB device
attached (confirmed zero port activity at ok>), then live
attach/detach/re-attach of a virtual USB thumb drive
(disk/usb-thumbdrive-test.img via usb-storage on xhci0.0). Full
connect->disconnect->connect cycle confirmed clean (no port wedge) on
amd64; single connect confirmed on aarch64 and riscv64.

Still open: correlating Command Completion Events back to their issuing
command, driving Enable Slot/Address Device from this connect path
(currently only a boot-time smoke test), and the callback surface into
Section U's higher-level code.

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).
