Robert Allan JamesandClaude Sonnet 5 b9c540a78b Artemis Milestone 2f: Configuration descriptor read + Mass Storage/BOT class confirmation
Chains off the device descriptor request via a new deferred-action mechanism
on xhci_dev_t (next_action/next_action_slot_id/next_action_length): a short
9-byte Configuration descriptor read learns wTotalLength, then a full read
retrieves Config+Interface+Endpoint descriptors, walked for the Interface
descriptor to confirm bInterfaceClass/SubClass/Protocol == Mass Storage/
SCSI/Bulk-Only Transport.

The deferral exists because ringing the next doorbell synchronously inside
xhci_poll_events()'s event-processing loop -- before the current event's
ERDP write -- hung the guest outright (confirmed live via checkpoint
logging, amd64). Fixed by moving the actual control-transfer submission to
a small dispatch at the end of xhci_poll_events(), after ERDP is updated.

A debug hack that shipped mid-session (forcing a repeated 9-byte read
instead of chaining into the real 44-byte length, to isolate whether the
hang was doorbell-ordering or length-specific) has been reverted: restored
the real length and re-verified live. The doorbell-ordering fix was the
whole story -- the 44-byte read completes cleanly.

Verified live via QMP hotplug, all three architectures, byte-identical
results: wTotalLength=0x2c, bInterfaceClass=0x08, bInterfaceSubClass=0x06,
bInterfaceProtocol=0x50 -- confirmed Mass Storage/SCSI/BOT. Disconnect
confirmed clean on every arch, no wedge. FABRIC-2.md Section X Milestone 2f
updated with the full writeup.

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).
